Read the REST Response Body into a StringBuilder

Demonstrates Rest.ReadRespSb, which reads the response body as text into a StringBuilder, replacing its previous contents.

Background. The staged request model separates sending from reading: a SendReq method transmits the request, ReadResponseHeader reads the status line and headers, and a ReadResp method reads the body. This gives fine control over large or streamed messages compared with the single-call full-request methods.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

success = rest.SendReqNoBody("GET","/api/items/123");
if (success == false) {
    console.log(rest.LastErrorText);
    return;
}

var statusCode = rest.ReadResponseHeader();
if (statusCode < 0) {
    console.log(rest.LastErrorText);
    return;
}

//  Read the response body as text into a StringBuilder, replacing its previous contents.
