Android Question Body ContentType not supported

[Bernaert Dominique]

Hi,

I'm having a problem uploading an image to a REST-api.
I get the following error Body contentType 'multipart/form-data;boundary=---------------------------1461124740692' not supported

This is the code I'm using:

Dim j As HttpJob
j.Initialize("", Me)
Dim fd As MultipartFileData
       
fd.Initialize
fd.KeyName = "Content"
fd.Dir = Provider.SharedFolder
fd.FileName = tempImageFile
fd.ContentType = "application/octet-stream"
   
j.PostMultipart(Main.BaseUrl & "projects/files/upload_image", CreateMap( "hash": "Test","user": "Hallo"), Array(fd))
j.GetRequest.SetHeader("Authentication", "bearer " & Main.Token)
   
Wait For (j) JobDone(j As HttpJob)
If j.Success Then
    Log(j.GetString)
End If
   
j.Release

I've tried several ContentTypes, but i cannot get it working.

What am i doing wrong?

Thx for some help

Are you sure that your server expects a multipart request?

Are you sure that your server expects a multipart request?

It expects a base64 json.
Sorry if i pose stupid questions, I'm pretty new to this.

Erel,

I tried with ContentType "application/json", but then i get an error message from the REST-api: No mapping for the Unicode character exists in the target multi-byte code page.

It expects a base64 json.

so instead of j.postmultipart then use j.postString instead and create the json with the JSON library.

"application/json"

if it is expecting a base64, then it is not a "application/json" but you should try both, with base64 json and raw json
