Lua - multi-part/form submission (Paperless-ngx API)
parkercP

Hi

I’ve been investing a lot of time recently trying to digitise everything I can, and my current adventure is with all my paper documents.

My tool of choice is Paperless-ngx, which so far is an amazing open source solution, and highly recommended if you’re interest in such a thing…

Such a move to Paperless would not be complete without some form of integration into Vera / openLuup, and thankfully it has a nice Rest API (https://paperless-ngx.readthedocs.io/en/latest/api.html) I can use. So far I’ve been able to make use the GET requests, to provide document counts etc., but it’s the mutipart/form data piece where I’m struggling..

The Curl command to upload a document, is as follows

curl -H "Authorization: Basic Y2hyaXM62tgbsgjunotmeY2hyaXNob3N0aW5n" -F "title=Companies House File 10" -F "correspondent=12" -F "document=@/mnt/nas/10.pdf" http://192.168.102.134:8777/api/documents/post_document/

But, I’d like to know how to do this with Lua code, more just to help me in my Lua learning curve, and what I thought would be reasonably straight forward thing to do, has turned out to be quite the opposite 🙂 Sending a multipart form data submission via http.request, is not as straight forward as I hoped. If anyone has any time to help, I’d appreciate some guidance on what I’m missing with the following, as based on the feedback, it looks like it not seeing the file (which I think I’ve confirmed by trying to sending both the curl and Lua commands to httbin.org ) …

local http = require("socket.http") local ltn12 = require("ltn12") local mime = require("mime") local lfs = require("lfs") local username = "username" local password = "password" local httpendpoint = 'http://httpbin.org/post' local filepath = "/mnt/nas/10.pdf" local file = io.open(filepath, "rb") local contents = file:read( "*a" ) -- https://stackoverflow.com/questions/3508338/what-is-the-boundary-in-multipart-form-data local boundary = "-----BoundaryePkpFF7tjBAqx29L" local send = "--"..boundary..

Lua : Downloading a file over https
parkercP

Hi,

I’m sure this is not a unique question about Vera (& Lua 5.1) and I’ve seen this reference in place,, but I can’t seem to find a fix to make an https download request work..

To give you an example, the code below aims to download 2 different files, the http call works fine, returning a 200 code, but the https one doesn’t, it doesn’t return anything ?

Please could some highlight what I’m missing?

print("--------DOWNLOAD http---------") local http = require("socket.http") local body, code = http.request("http://pbs.twimg.com/media/CCROQ8vUEAEgFke.jpg") print(code) if not body then error(code) end local f = assert(io.open('mnt/nas/webtest1.jpg', 'wb')) -- open in "binary" mode f:write(body) f:close() print("--------DOWNLOAD https---------") local https = require "ssl.https" --luasec local body, code = https.request("https://u.cubeupload.com/jbcooper/16146313918060.jpg") print(code) if not body then error(code) end local f = assert(io.open('mnt/nas/webtest2.jpg', 'wb')) -- open in "binary" mode f:write(body) f:close()

Luup : Fitbit API
parkercP

Hi

I’m trying out the Fitbit api, not only to extract some activity data for a potential plugin, but also to learn more about OAuth 2.0. More details can be found here..

Fitbit Development: Getting Started Fitbit Development: Getting Started

You'll fit in here. Using JavaScript, CSS, and SVG, developers now have a fast, easy way to build apps and clock faces for Fitbit OS.

In addition to having a fitbit account, to get going with any integration, you need to register your app, via here..

Login

With an app registered, I’ve called mine “VERA” , I’ve written chunks of Lua code to support the various steps, (completed manually) my goal now is to try and put them all together into functions to be called in sequence on my Vera and/or OpenLuup.

Where I’m getting stuck is with the authorisation code step, which Fitbit provides appended to the domain name I registered with them when registered my app ..

Here’s an example of a redirect URL that Fitbit will redirect the user too, with their associated authorisation code, which I need in the process later on to obtain the required access token. (More specific details are here - https://dev.fitbit.com/build/reference/web-api/developer-guide/authorization/ )

https://myapp.com/callback?code=d62d6f5bdc13df79d9a5f#_=_

And it’s the d62d6f5bdc13df79d9a5f part of that new page/URL which I need..

How best do i capture/process the URL call Fitbit issues?

I assume this is where a luup.register_handler would come in, and I could register my Vera handle (using https ?, as that’s required by Fitbit) as the redirect domain/url e.g.

https://veraip:3480/data_request?id=lr_fitbit&

So Fitbit would redirect to..

https://veraip:3480/data_request?id=lr_fitbit&/?code=d62d6f5bdc13df79d9a5f#_=_

But that doesn’t seem to work..

Any suggestions on how to do this would be appreciated..

function FitbitRequestHandler(lul_request, lul_parameters, lul_outputformat) for k,v in pairs(lul_parameters) do luup.log ('fitbit_Handler: parameters are: '..tostring(k)..'='..tostring(v)) end if next(lul_parameters) == nil then luup.log("lul_parameters Table is empty") end local html = "</html><head>" .. "</head>" .. "<body>" .. "PRINTING" .. "\n" .. " lul_request: " .. tostring(lul_request) .. "\n" .. " lul_parameters: " .. tostring(lul_parameters) .. "\n" .. " lul_outputformat: " .. tostring(lul_outputformat) .. "\n" .. "</body></html>" return html, "text/html" end luup.register_handler("FitbitRequestHandler", "fitbit")

Thanks is advance…

Luup : Error Handling
parkercP

Hi,

Please could people share how they are presenting and handling errors in their Vera / OpenLuup plugins, I’ve tried to look through various Implementation files, but very few seem to have anything, other than perhaps a luup.task (which for some reason doesn’t work for me) ?

Below is the startup and check/validation functions for a plugin I’m working on..

function checkIPPowerSetUp(lul_device) log("Checking if parent device is configured correctly...") ipAddress = luup.devices[lul_device].ip -- check if parent device has an ip address assigned if ipAddress == nil or ipAddress == "" then -- if not stop and present error message luup.task('ERROR: IP Address is missing',2,'IPPower',-1) debug("ERROR: IP Address is missing " ..ipAddress.. " unable to progress") return false else -- if one is provided, present success message luup.task('IP Address for IPPower 9258 present, setup continues',4,'IPPower',-1) debug("IPPower StartUp activated - Device #" .. lul_device .. " now creating children") createChildIPPowerOutlets(lul_device) luup.call_delay("IPPowerPoller", 5) return true end end function IPPowerStartup(lul_device) -- set attributes for parent device luup.attr_set( "name", "IPPower 9258", lul_device) luup.attr_set( "category_num", "3", lul_device) luup.attr_set( "subcategory_num", "1", lul_device) luup.variable_set("urn:nodecentral-net:serviceId:IPPower1", "Icon", 1, lul_device) luup.variable_set("urn:nodecentral-net:serviceId:IPPower1", "PluginVersion", PV, lul_device) checkIPPowerSetUp(lul_device) log("Start up, Parent device created...") end </functions> <startup>IPPowerStartup</startup>

What’s the best way to present errors to the user, and make iot clear what they need to do ?

Under certain circumstances (thanks @DesT!) I see that it's causing a luup reload infinite cycle, because child devices are being created, then deleted. Specifically, I see this in the logs:

Vera StaticJSON Help - Showing a button’s status/selection (in/out) in the UI ?
parkercP

Hi

I’m putting the finishing touches to a HDMI Matrix plugin, and while I have it working well - I can’t find anything on the Vera/MIOS wikis that tells me how I can show if a UI button is pressed or not (to reflect a input choice that is selected)

Here’s a screenshot of the child outputs I’ve created for the Matrix switcher. (The plugin creates a parent device and then 4 children to show the Matrix Outputs - parent is not shown - and the idea is that’s you select the input number for the respective output)

BB5B6001-294E-4AE9-A095-D2E639F56B9C.jpeg

Here is an extract of the button element in the associated JSON file used for the child devices..

{ "ControlGroup": "1", "ControlType": "button", "top": "0", "left": "0", "Label": { "lang_tag": "Input1", "text": "Input1" }, "Display": { "Top": 60, "Left": 50, "Width": 75, "Height": 20 }, "Command": { "Service": "urn:nodecentral-net:serviceId:SYMatrix1", "Action": "SYCall", "Parameters": [ { "Name": "action", "Value": "I1" } ] } },

The associated command calls the parent implementation file SYCall - (The value “I1” relates to a element of the URL that needs to be called to select that associated input)

<action> <serviceId>urn:nodecentral-net:serviceId:SYMatrix1</serviceId> <name>SYCall</name> <run> SYMatrix.SYCall(lul_device, lul_settings.action, lul_settings) </run> </action>

And then the Lua file (L_****) has holds the SYCall function

function SYCall (deviceNo, action, settings) ….. end

I’ve just started to have a play with iOS Shortcut and one of my test cases is to see if I can do the following

select a a file (.lua or .txt) on my iPad extract the entire script/contents encode the data obtained append the encode content to the end of the RunLua action. call the URL http://myIP/data_request?id=lu_action&serviceId=urn:micasaverde-com:serviceId:HomeAutomationGateway1&action=RunLua&Code=

Below is a screenshot of the workflow I have built in Shortcuts, which seems pretty straight forward, and it does generate a encoded URL, however the actual request itself does not complete. I get an ‘OK’ response back eventually, but the code is not actioned, and the logs don’t seem to tell me anything..

FAB8DB5F-9003-4624-BCF3-8F536A660D21.jpeg

The code I’m extracting from the Lua file works fine in the test Lua window, so i’m not sure what’s occurring differently, between the two routes, maybe it’s the encryption being used ?..

Is anyone able to help me test this, and see if they can generate a long / multi line RunLua encoded URL (if not via Shortcut, then by some that can help me with the root cause to then address that in Shortcut

Add-on - Aviosys IPPower 9258
parkercP

Hi

Picking up from another thread this is to focus on the creation of the 4 key elements of a new Plugin for my Aviosys IPPower 9258, which are quite old, and I don’t believe are made anymore, but they seem to have a simple http api interface to cut my teeth on with a plugin.

First the device file, which is to support the creation/set up of the device, and here I explain what it is, tell Vera what the implementation file and .json file is, and also leverage the pre-existing Switch and HA capabilities..

Device File - D_IPPower.xml

<?xml version="1.0"?> <root xmlns="urn:schemas-upnp-org:device-1-0"> <specVersion> <major>1</major> <minor>0</minor> </specVersion> <device> <deviceType>urn:nodecentral-net:device:IPPower:1</deviceType> <staticJson>D_IPPower1.json</staticJson> <manufacturer>Aviosys</manufacturer> <modelDescription>IPPowerSwitch</modelDescription> <modelName>IPPower9258</modelName> <handleChildren>1</handleChildren> <implementationList> <implementationFile>I_IPPower1.xml</implementationFile> </implementationList> <serviceList> <service> <serviceType>urn:schemas-upnp-org:service:SwitchPower:1</serviceType> <serviceId>urn:upnp-org:serviceId:SwitchPower1</serviceId> <SCPDURL>S_SwitchPower1.xml</SCPDURL> </service> <service> <serviceType>urn:schemas-micasaverde-com:service:HaDevice:1</serviceType> <serviceId>urn:micasaverde-com:serviceId:HaDevice1</serviceId> <SCPDURL>S_HaDevice1.xml</SCPDURL> </service> </serviceList> </device> </root>

Next it is the Implementation file, which thanks to the feedback on this forum, will focus on a specific Lua file, where all the code will be, the only thing I need to add here are the Actions (what do I want it to be able to do etc.)

Implementation file - I_IPPower.xml

<?xml version="1.0"?> <!-- I_IPPower.xml; Vera/openLuup "IPPower 9258" Plug-in V1.1 Nov 2021 --> <implementation> <settings> <protocol>crlf</protocol> </settings> <files>L_IPPower1.lua</files> <startup>IPPowerStartup</startup> <actionList> <action> <serviceId>urn:upnp-org:serviceId:SwitchPower1</serviceId> <name>SetTarget</name> <job> local url = "http://" .. ipAddress .. "/set.cmd?user=admin+pass=12345678+cmd=setpower+" .. luup.devices[lul_device].id .. "=" .. lul_settings.newTargetValue luup.log("Sending command " .. url) local status, data = luup.inet.wget(url) if (data) then debug("Data received = " .. data) else log("No Data received !! ") end local value = string.match(data, luup.devices[lul_device].id.."=(%d)") if (value) then luup.variable_set("urn:upnp-org:serviceId:SwitchPower1", "Status", value, lul_device) else log("Value returned is empty") end </job> </action> </actionList> </implementation>

The other two files D_IPPower.json, and L_IPPower.lua are still being worked on so i will add later …

If anyone notices any improvement

Lua : storage.set , storage.get
parkercP

Hi

I’ve seen storage.set and storage.get used in some Lua code posted on the internet, where they need to store/retrieve somethings, e.g.

iv = encdec.base64dec(challenge_Key)     storage.set('IV', iv)

and then later on within another function I see..

iv = storage.get('IV')

It makes sense how this is meant to work, and it seems such a simple/elegant feature - hence I was wondering, is there an equivalent in Vera/OpenLuup? As I’d naturally go to use luup.variable_set and luup.variable_get - but that requires a device to be used etc.

Get your Alexa replies to the device you've asked them to with VeraAlexa plug-in
therealdbT

So, I was messing with my Alexa routines and ha bridge, and I want to share something very cool you could do with the ability to get the last Alexa that heard your command. I mentioned it a couple of times on the old place, but Vera's OS is missing the jq package, but openLuup could have it installed.

Basically, just execute -lastalexa with my VeraAlexa plug-in:

local lastAlexa = luup.call_action("urn:bochicchio-com:serviceId:VeraAlexa1", "RunCommand", {Command="-lastalexa"}, 666)

Then use it in your scene, to dynamically generate your TTS response with the device you've asked your question seconds before!

local temperature = 25 -- get it from your sensor luup.call_action("urn:bochicchio-com:serviceId:VeraAlexa1", "Say", {Text="Ok, outise temperature is " .. temperature .. " degree", Volume=50, GroupZones= lastAlexa, Repeat = 2}, 666

Very cool indeed 🙂

function Delay1() --[[HDMI Matrix B1--]] local socket = require("socket") tcp = assert(socket.connect("192.168.255.204", 4998)) tcp:send("sendir,1:3,1,38000,1,69,341,171,22,21,22,21,22,21,22,21,22,21,22,21,22,21,22,21,22,64,22,64,22,64,22,64,22,64,22,64,22,64,22,64,22,21,22,21,22,64,22,21,22,64,22,21,22,21,22,21,22,64,22,64,22,21,22,64,22,21,22,64,22,64,22,64,22,1493,341,85,22,3669" .. "\r\n") luup.sleep(1050) tcp:close() end luup.call_delay("Delay1", 1) function Delay2() --[[HDMI Matrix B2--]] local socket = require("socket") tcp = assert(socket.connect("192.168.255.204", 4998)) tcp:send("sendir,1:3,1,38000,1,69,343,171,21,21,22,21,22,21,22,21,21,21,22,21,22,21,21,21,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,63,22,21,22,63,22,21,21,21,22,21,22,21,21,22,21,21,22,63,22,21,22,63,22,63,22,63,22,1528,342,85,22,1528" ..

io.popen: cannot allocate memory error
therealdbT

I have a script calling io.popen to get the file system partition info, running on the Vera to check for space, and it's getting "cannot allocate memory error".

Any suggestions, beside doing a luup.reload?

Code/Snippet library
Something smarter than string.format for user-defined patterns?
therealdbT

In my Virtual HTTP plugin I have patterns that could be specified to dynamically compose HTTP URLs based on current values. So, if you enter
http://myip/color?v=%s

it gets replaced with the current color. It's very handy when having more parameters, or if your parameter is in a different position.

The problem is that from time to time, there are users with legitimate % in their URLs (since it's the escape char in URLs, after all) and this is causing weird behavior or crash.

So, I want to find something smarter to support both.
Any hints here is appreciated.

    I’ve just started to have a play with iOS Shortcut and one of my test cases is to see if I can do the following

    1. select a a file (.lua or .txt) on my iPad
    2. extract the entire script/contents
    3. encode the data obtained
    4. append the encode content to the end of the RunLua action.
    5. call the URL
    http://myIP/data_request?id=lu_action&serviceId=urn:micasaverde-com:serviceId:HomeAutomationGateway1&action=RunLua&Code=

    Below is a screenshot of the workflow I have built in Shortcuts, which seems pretty straight forward, and it does generate a encoded URL, however the actual request itself does not complete. I get an ‘OK’ response back eventually, but the code is not actioned, and the logs don’t seem to tell me anything..

    FAB8DB5F-9003-4624-BCF3-8F536A660D21.jpeg

    The code I’m extracting from the Lua file works fine in the test Lua window, so i’m not sure what’s occurring differently, between the two routes, maybe it’s the encryption being used ?..

    Is anyone able to help me test this, and see if they can generate a long / multi line RunLua encoded URL (if not via Shortcut, then by some that can help me with the root cause to then address that in Shortcut

      Things I notice:

      1. URL does not have device number (DeviceNum=0)
      2. Should use id=action not id=lu_action (updated standard)
      3. Code value is not base64-encoded on this function, which means the code must be URL-encoded as all query parameters in a GET request must be, and if the total length of the request URL including query parameters is more than 1024 bytes, you must use POST rather than GET for the request and pass the query parameters in the body (MIME type application/x-www-form-urlencoded, specified in the Content-Type header for the request).
      4. You're not showing the final "encoded" URL as submitted, or stating what encoding you are using (you just say "encode the data obtained" and not what kind), so any of that could be incorrect and we wouldn't know/be able to tell you.
      5. Luup is pretty good at logging action requests as received, irrespective of their eventual success, so if you're not finding this in the logs, it's either not getting to the box or you're not looking for the right thing. A search for RunLua should find the entries.

        Thanks, i had it working, with lu_action, but will look to update to ensure it’s current..

        OK, that makes it interesting, I’ll have to add some sort of character count in to the workflow....

        Yeah, sorry I’m testing it with a Prowl notification URL, which has my API key in, so didn’t want to post that, but will show it as working example lower down

            That URL is 1126 bytes, too long for a GET. The browser is automatically shifting to POST as I described. You'll need to do the same.

              Okay, it will be a long road of trial and error without mastering the language yet.
