TSslHttpRest with multipart/form-data

Recommended Posts

How to send files to an API using TSslHttpRest? In Postman I can, this is the http code:

POST /api/br-invoice-integration/v1/batches HTTP/1.1
Host: qed.onvio.com.br
Accept: application/json
Authorization: Bearer 42dc0b99-2d17-4898-9c85-0b52ae364c63Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

Content-Disposition: form-data; name="file[]"; filename="/C:/MyFile.xml"
Content-Type: text/xml

Content-Disposition: form-data; name="query"


With SslHttpRest, I'm trying to SendStream, like that (similar to the sample OverbyteIcsHttpPost1):

  FileName := 'C:\MyFile.xml';

  RandBoundary := '-----------------------------' +
    IntToHex(Random(MaxInt), 8) + IntToHex(Random(MaxInt), 8);

  SslHttpRest1.ContentTypePost := 'multipart/form-data; boundary=' + RandBoundary;

  Header := RandBoundary + #13#10 +
    'Content-Disposition: form-data; name="file[]"; filename="' +
    'MyFile.xml' + '"' + #13#10 +
    'Content-Type: text/xml' +
    #13#10 + #13#10;

  Footer := RandBoundary + #13#10 +
    'Content-Disposition: form-data; name="query"' + #13#10 + #13#10 +
    '{"boxe/File":true}' + #13#10 + RandBoundary + #13#10;

  SslHttpRest1.SendStream := TMultiPartFileReader.Create(Filename, Header, Footer);
  SslHttpRest1.SendStream.Position := 0;

  SslHttpRest1.RestRequest(httpPOST, Myurl);

But it doesn't work, just get error:

Request completed: 500 
Request done, StatusCode #500
{"error":{"code":500,"errors":[],"message":"HTTP 400 Bad Request"}}

Has anyone ever needed to do something similar, would this be the way? If anyone can help, I appreciate it.

While ICS has MIME decoding units,  the only multipart/form-data encoding is in the OverbyteIcsHttpPost1 sample you've found. 


I think you need to set DebugLevel to DebugBody and makes sure your POST content is logged to see what the component is actually sending to the server.
