PostAgent and XMLRPC - howto?

[nata-lee]

Hello!
Huginn makes my life easier, but some times I'm confused.

I'd like to use xml-rpc with the PostAgent. Specification here: http://xmlrpc.scripting.com/spec.html
But I can't build the sctucture with multiple parameters with the same name. Huginn doesn't let me do this, it's always a json error.
My agent:
{ "post_url": "http://domain/xmlrpc.php", "expected_receive_period_in_days": "1", "content_type": "xml", "method": "post", "no_merge": "true", "xml_root": "methodCall", "payload": { "methodName": "wp.newPost", "params": { "param": { "value": "1" } } }, "headers": {}, "emit_events": "false" }

I need more and multible but how? What am I doing wrong?
Could you help me?

Hi @nata-lee, I've never actually used true XML-RPC. (As opposed to ajax, which is usually JSON these days.) You may want to have Huginn post to a server that logs your requests, to make sure they look right. http://requestb.in/ could be useful here.

Hi @cantino, thank you for the answer.
Well, I have no problem with XML-RPC then I use curl. And requests and responds are the next step.
I'm confused how to format XML-RPC xmls (and all xmls in general) with huginn interfase and the PostAgent. I tried to form the request as I wrote in the last message, but I can't understand how to get such structure as:

<methodCall>
   <methodName>examples.getStateName</methodName>
   <params>
      <param>
         <value><i4>41</i4></value>
         </param>
      <param>
         <value><user>testname</user></value>
         </param>
      </params>
   </methodCall>

I just need an example.

The following JSON options are pretty close:

{
  "post_url": "http://requestb.in/123456",
  "expected_receive_period_in_days": "1",
  "content_type": "xml",
  "method": "post",
  "payload": {
    "methodName": "examples.getStateName",
    "params": [
      {
        "value": {
          "i4": "41"
        }
      }
    ]
  },
  "headers": {},
  "emit_events": "false",
  "xml_root": "methodCall"
}

When pointing at a requestbin I made, I got this:

@cantino I think the problem is the to_xml serializer can not generate multiple params elements which have the same parent.

[cantino]

Wait, what's the problem? Isn't might output what @nata-lee is looking for?

[nata-lee]

@dsander is quite right. I can't get multiple param in the params.

<params>
 <param>123</param>
 <param>456</param>
</params>

is impossible via huginn interface :( Or I don't know how to get it, so I asked my question.
Maybe any workaround? Now I have to use Shell Command Agent insteed of the PostAgent,and it's some kind of unsecure.

[dsander]

I don't think that is possible at the moment, but I am planning to change the PostAgent to allow sending arbitrary data which can be formatted using liquid.

[dsander]

@nata-lee With #1402 merged you will be able generate the XML yourself and setting it in the payload as a string.

[dsander]

I don't think that will ever be possible with the way to_xml works however the workaround to to manually construct the XML structure should work.

Please feel free to reopen if you need further assistance!
