PostMultipart : have problem as there's chinese character in partsToSend

[RC_8716579]

Hello, recently I use PostMultipart, and these's chinese character in my partsToSend
so I set the headers like this:

var params = {
proxyScheme: undefined /* STRING */,
headers: {"Content-type":"multipart/form-data; charset=UTF-8"} /* JSON */,
ignoreSSLErrors: undefined /* BOOLEAN */,
useNTLM: undefined /* BOOLEAN */,
partsToSend: formData /* INFOTABLE */,
workstation: undefined /* STRING */,
useProxy: undefined /* BOOLEAN */,
repository: undefined /* STRING */,
proxyHost: undefined /* STRING */,
url: url /* STRING */,
};

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

Here I print out the content which api server received:

Red: If I remove the content of headers, every chinese character  will become to "?"
Orange: There's no problem as I use Postman to test the api

Green: the content which api server received will become to nothing as setting the headers

I also try to set headers: {"Content-type":"charset=Big5"} but the result is the same as UTF-8

anyone can help me?
thanks a lot!

Hi @RC_8716579 

What version of ThingWorx are you running?  Can you provide more detail around your use case?  What are you sending it to?

Regards.

The version of Thingworx is 8.4.

In the detail, I write the RESTful API by golang and test it by postman, it seems work normally.
And I want Thingworx to get the data from the API by POST method.

Is it not ok to use form-data ?

Hi @RC_8716579 

Do you get any results for non-chinese characters or is it always blank?

Can you clarify what the target and source servers are?

We're going to test this under a recent release as ThingWorx 8.4 is no longer supported.

Regards.

Hi Slangley,

Sorry for the late reply.

We always get the "?" characters while using the "PostMultipart" function to post form-data to our owned APIs.

Our APIs server is just run by simple GET/POST HTTP methods for RESTful services.

Recently we solved this problem by using the "PostJSON" function, it's weird it works with a different function but the same body and server.

Hope that we can find out the problem with the "PostMultipart" function, thank you.

Hi @RC_8716579.

Glad you found a workaround.  Is it possible you were working with JSON instead of an infotable?  Can you provide the code you used for generating the infotable?

Regards.
