Skip to main content

I cannot upload to the Box by calling API in the Azure Data Factory.
I can not use SDK and I got HTTP 400 error ,
“Malformed stream”
following is the Body that I created in the Azure pipeline:( it should be in JSON format)

@concat('--------------------------9fd09388d840fef1
content-disposition: form-data; name=“attributes”

{“name”:“testdev.xlsx”, “parent”:{“id”:“0”}}
--------------------------9fd09388d840fef1
content-disposition: form-data; name=“file”; filename=“testdev.xlsx”
content-type: text/csv

‘, variables(‘varFileContents’),’

--------------------------9fd09388d840fef1–
')

Hi @Shrpmn

Welcome to the forum!

I dont see anything particularly wrong with your request, however creating a upload request by hand is always tricky.

I wonder if Azure doesn’t have a method to make this easier, you might be missing the proper binary upload it self…

As an example, here is a cUrl log from an upload to box:

POST /api/2.0/files/content?fields=id%2Ctype%2Cname HTTP/2
Host: upload.box.com
User-Agent: curl/8.4.0
Accept: */*
Authorization: Bearer 1!k...PVWw.
Content-Length: 423429
Content-Type: multipart/form-data; boundary=------------------------i2ozkLjczzSHhtVvcYCBSQ

 

--------------------------i2ozkLjczzSHhtVvcYCBSQ
Content-Disposition: form-data; name="attributes"
{.  "name": "upload-test.png",.  "parent": {.    "id": "253757099719".  }.}

Of course the binary is impossible to display as text, hence the dots.

Let us know if this helps.
