(JavaScript) Send JSON REST Request, Get JSON Response

Demonstrates sending a RESTful JSON request, and receiving a JSON response. This example will create a bucket in Google Cloud Storage (which involves sending and receiving JSON).

Note: This example requires Chilkat v11.0.0 or greater.

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;

// This example will create a bucket in Google Cloud Storage.

// It requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var gAuth = new CkAuthGoogle();
// Obtain an access token as shown in one of the following examples:
// See Get Access Token using a Service Account JSON Key
// See Get Access Token using a P12 File

var rest = new CkRest();

// Connect using TLS.
var bAutoReconnect = true;
success = rest.Connect("www.googleapis.com",443,true,bAutoReconnect);

// Provide the authentication credentials (i.e. the access key)
success = rest.SetAuthGoogle(gAuth);

// Build the JSON request body for creating a bucket.
// The only required property is the "name", but we'll add more
// to make a better example..
var jsonReqBody = new CkJsonObject();
jsonReqBody.AppendString("name","chilkat-bucket-c");
jsonReqBody.AppendString("kind","storage#bucket");
jsonReqBody.AppendString("location","US");

var objVersioning = new CkJsonObject();
jsonReqBody.AppendObject2("versioning",objVersioning);
objVersioning.AppendBool("enabled",true);

// Show the HTTP request body we'll be sending.
console.log(jsonReqBody.Emit());

// Add the required query parameter.
// See https://cloud.google.com/storage/docs/json_api/v1/buckets/insert
success = rest.AddQueryParam("project","chilkattest-1050");

// Add the Content-Type HTTP request header.
success = rest.AddHeader("Content-Type","application/json; charset=UTF-8");

var jsonResponseStr = rest.FullRequestString("POST","/storage/v1/b",jsonReqBody.Emit());
if (rest.LastMethodSuccess == false) {
    console.log(rest.LastErrorText);
    return;
}

// Show the JSON response.  (See below for a sample JSON response.)
console.log("Json Response: " + jsonResponseStr);
