How to post file using api.

Chris Howell — Tue, 05 Oct 2021 18:46:03 GMT

Hello everyone,

I am trying to upload file as multipart/form-data using clientconnection. But it failed.

This is my code.

void ExportIFC::ExportData(const char* buffer, UINT32 size) { using namespace HTTP::Client; using namespace HTTP::MessageHeader; using namespace HTTP::Encoding; IO::URI::URI connectionUrl(LINKURL); ClientConnection clientConnection(connectionUrl); clientConnection.Connect(); GS::UniString url = "/upload/" + this->m_projectId + "/" + this->m_uploadHandle; Request postRequest(Method::Post, url); RequestHeaderFieldCollection& headers = postRequest.GetRequestHeaderFieldCollection(); GS::UniString bearer = "bearer " + this->m_token; headers.Add(HeaderFieldName::Authorization, bearer); headers.Add(HeaderFieldName::ContentType, "multipart/form-data"); headers.Add("Content-Disposition", "form-data; name=\"file\"; filename=\"test.ifc\""); BodyOBinaryChannel& outChannel = clientConnection.BeginSend(postRequest); outChannel.Write(buffer, size); Response response; clientConnection.Receive(response); StatusCode::Id code = response.GetStatusCode(); if (code == StatusCode::OK) { // post process } } clientConnection.FinishReceive(); clientConnection.Close(false); }

What is my fault? Please help me.

Don't you need a clientConnection.FinishSend(); ?

Hey! Was you able to achieve this? I'm trying it too, with clientConnection.FinishSend(), but I'm getting some errors from the server, maybe due how I'm writing. Shouldn't boundaries be written?

Hi,
I could not to upload the file with clientconnection.
So I solved the problem using cURL.

Nice! I solved as well, but using libcpr (a curl wrapper that is very easy to use)
