Hello I am trying to POST XML data

I have read in the documentation

postData: Optional. When doing a POST this data will be the payload of the request (body). If you provide a Lua table then this will automatically be converted to json and the request-header application/json is set. So no need to do that manually.

Does this mean that my XML is converted to JSON

Code: Select all

       
       local function url_encode(str)
            if (str) then
                str = string.gsub (str, "\n", "\r\n")
                str = string.gsub (str, "([^%w %-%_%.%~])",
                function (c) return string.format ("%%%02X", string.byte(c)) end)
                str = string.gsub (str, " ", "+")
            end
            return str
        end
       
       local press  = '<key state="press" sender="Gabbo">PRESET_4</key>';
       press = url_encode(press)
             
       domoticz.openURL({
            url = 'http://192.168.***.***:8090/key',
            method = 'POST',
            callback = 'Retrieved',
            postData = press
         })

In my call back I receive the following message from item.data: "Error parsing request"

I want to use this to start my Bose Soundtouch (I am not able to get the library that is available working)

Have you tried without the urlencode (btw, there is a url encoder in dzVents (domoticz.utils.urlEncode()) see the docs). And no, xml data is not converted to json by dzVents coz that's far from trivial. Maybe the bose interface also has json support. And you can check the response headers to see what is going on. And.. you can test the api with apps like Postman to see if your request is correct.

If I dont'use urlEncode then only PRESET_1 is sent als postData. that gave the same error.
Just did a try with the urlEncode but with dzVents (domoticz.utils.urlEncode()) also same reply.

If I go through the BOSE soundtouch documentation there is only XML requests no JSON at all.

The error I get from postman is

<?xml version="1.0" encoding="UTF-8" ?>
<errors deviceID="A81B6A28DD44">
<error value="1019" name="CLIENT_XML_ERROR" severity="Unknown">Error parsing request</error>
</errors>

If I send the request with jquery in JavaScript it works

var press = '<key state="press" sender="Gabbo">PRESET_4</key>';
var release = '<key state="release" sender="Gabbo">PRESET_4</key>';
$.ajax({
type :'post',
url : 'http://'+ip+':8090/key',
cache : false,
data : press,
dataType: 'xml',
success :function(xml) {

}
})

The problem has been solved
I had to add a header.

Code: Select all

            local press  = '<key state="press" sender="Gabbo">NEXT_TRACK</key>';
            domoticz.openURL({
                url = 'http://192.168.178.100:8090/key',
                method = 'POST',
                callback = 'Retrieved',
                headers = 'application/xml',
                postData = press
            })

If the header is missing there is a parse error. (state and sender are missing)
