(C#) Creating an application/json HTTP POST RequestDemonstrates how to create an HTTP POST request having the Content-Type application/json, where the body of the HTTP request is the following JSON: { "username" : "my_username", "password" : "my_password", "validation-factors" : { "validationFactors" : [ { "name" : "remote_address", "value" : "127.0.0.1" } ] } } The generated HTTP request looks like this: POST /something HTTP/1.1 Content-Type: application/json Accept: application/json Host: domain Content-Length: 216 { "username": "my_username", "password": "my_password", "validation-factors": { "validationFactors": [ { "name": "remote_address", "value": "127.0.0.1" } ] } }
// This example demonstrates building an application/json request. Chilkat.HttpRequest req = new Chilkat.HttpRequest(); // The ContentType, HttpVerb, and Path properties should // always be explicitly set. req.HttpVerb = "POST"; req.Path = "/something"; req.ContentType = "application/json"; // We may wish to add an "Accept" header to the request. // This tells the server we'll accept an application/json response. req.AddHeader("Accept","application/json"); // We'll use Chilkat's JSON API to create the JSON body of the HTTP request. Chilkat.JsonObject json = new Chilkat.JsonObject(); json.AppendString("username","my_username"); json.AppendString("password","my_password"); Chilkat.JsonObject vFactors = json.AppendObject("validation-factors"); Chilkat.JsonArray vArray = vFactors.AppendArray("validationFactors"); vArray.AddObjectAt(0); Chilkat.JsonObject factorObj = vArray.ObjectAt(0); factorObj.AppendString("name","remote_address"); factorObj.AppendString("value","127.0.0.1"); // Use the JSON for the HTTP request body // By default, the Emit method will output compact JSON. // This is best for generating the smallest size request. // To generate a more human-readable (pretty-printed) JSON request body, // set the EmitCompact property to FALSE json.EmitCompact = false; req.LoadBodyFromString(json.Emit(),"utf-8"); // View the request that would be sent if SynchronousRequest was called: string requestMime = req.GenerateRequestText(); Debug.WriteLine(requestMime); // A few important comments about the HTTP request that is generated: // // 1) The Content-Length header is automatically generated based on the actual length of the MIME message // that follows the intial (topmost) MIME header. // 2) The HOST header will automatically get filled in with the actual domain when SynchronousRequest // is called |
