(C# UWP/WinRT) 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).

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

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

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

Chilkat.AuthGoogle gAuth = new Chilkat.AuthGoogle();
//  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

Chilkat.Rest rest = new Chilkat.Rest();

//  Connect using TLS.
bool bAutoReconnect = true;
success = await rest.ConnectAsync("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..
Chilkat.JsonObject jsonReqBody = new Chilkat.JsonObject();
success = jsonReqBody.AddStringAt(-1,"name","chilkat-bucket-c");
success = jsonReqBody.AddStringAt(-1,"kind","storage#bucket");
success = jsonReqBody.AddStringAt(-1,"location","US");
success = jsonReqBody.AddObjectAt(-1,"versioning");

Chilkat.JsonObject pObjVersioning = jsonReqBody.ObjectOf("versioning");
success = pObjVersioning.AddBoolAt(-1,"enabled",true);

//  Show the HTTP request body we'll be sending.
Debug.WriteLine(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");

string jsonResponseStr = await rest.FullRequestStringAsync("POST","/storage/v1/b",jsonReqBody.Emit());
if (rest.LastMethodSuccess != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

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