ContentLoaderFunctions PostMultipart Help Needed

  • May 1, 2018

I am trying to manually import an XML file to the Thingworx Manual Importer feature using the service "PostMultipart" in the ContentLoaderFunctions resource.  Does anyone have any examples of using this service?

I have the needed file in the correct repository, however, the POST isn't doing anything.  I suspect I need to do something with the service parameter "partsToSend", but I don't know what.  I am not even sure what the structure of the InfoTable needs to be for that parameter.

 

Anyone have any ideas?

I did an import using the standard Thingworx import dialog and below is the HTTP request structure from Chrome Dev Tools.  Anyone know how to specify the "Request Payload" in an HTTP request from a Thingworx service?

 

From Chrome Dev Tools:

Request URL: http://server/Thingworx/Importer?purpose=import&usedefaultdataprovider=false&WithSubsystems=false
Request Method: POST

This guide his some pertinent information:

https://developer.thingworx.com/resources/guides/rest-api-how-guide/extensions-rest-api-how

 

You must include this header in your request:

X-XSRF-TOKEN:TWX-XSRF-TOKEN-VALUE

The format of multi-part POSTs is fairly complicated, you should use an HTTP client library to create it in whatever language you are programming in

I did find that I need to include that header.  I have been able to successfully import an xml file using Postman, but I haven't had any success doing the same from a Thingworx service.

 

I could create a Java extension, but I'd rather use the standard platform if possible.

Here's the example on how to use PostMultipart from ContentLoaderFunctions:

 

  • To send the Request Parameters as text (InfoTable) :-
var table = Resources["InfoTableFunctions"].CreateInfoTable();

//Add new fields to the InfoTable:
table.AddField({name: "name", baseType: "TEXT"});
table.AddField({name: "email", baseType: "TEXT"});
table.AddField({name: "age", baseType: "NUMBER"});

// add data row
table.AddRow({
 name : "Your Name",
 email : "youremail@domain.com",
 age : 24
});

var params = {
	url: "http://www.example.com/api/yourservice" /* STRING */,
	partsToSend: table /* INFOTABLE */,
};

// result: JSON
var result = Resources["ContentLoaderFunctions"].PostMultipart(params);

 

  • To send the Request Parameters as file :-

 

var params = {
	url: "http://www.example.com/api/yourservice" /* STRING */,
	repository: "FilesStorage" /* STRING */,
	pathOnRepository: "path/to/your/file/testfile.txt" /* STRING */,
};

// result: JSON
var result = Resources["ContentLoaderFunctions"].PostMultipart(params);

(Here value of repository represents the name of the FileRepository on your Thingworx Environment)

 

Hope it will help 🙂
