Send a Staged REST Request with a Streamed Body

See more REST Examples

Demonstrates Rest.SendReqStreamBody, which sends a request whose body is read from a Stream, then reads the response in separate steps.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

bool success = false;

Chilkat.Rest rest = new Chilkat.Rest();
bool bTls = true;
bool bAutoReconnect = true;
success = rest.Connect("example.com",443,bTls,bAutoReconnect);
if (success == false) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

//  The file paths are relative to the application's current working directory.  Absolute paths
//  may also be used.  Supply the paths appropriate to your own environment.

//  The request body is read from a Stream whose source is a local file.
Chilkat.Stream bodyStream = new Chilkat.Stream();
bodyStream.SourceFile = "qa_data/upload.json";

rest.AddHeader("Content-Type","application/json");

//  Send the request, reading the body from the stream.  The 3rd argument is the Stream.
success = rest.SendReqStreamBody("POST","/api/upload",bodyStream);
if (success == false) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

//  After sending, read the response status line and header fields.  The return value is the HTTP
//  status code, or -1 if no response was received.
int statusCode = rest.ReadResponseHeader();
if (statusCode < 0) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

Debug.WriteLine("Response status code: " + Convert.ToString(statusCode));

//  Read the response body as text.
string responseBody = rest.ReadRespBodyString();
if (rest.LastMethodSuccess == false) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

Debug.WriteLine(responseBody);
