(Go) Send JSON REST Request, Get JSON ResponseDemonstrates 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).
// This example will create a bucket in Google Cloud Storage. var success bool // It requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. gAuth := chilkat.NewAuthGoogle() // 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 rest := chilkat.NewRest() // Connect using TLS. 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.. jsonReqBody := chilkat.NewJsonObject() 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") pObjVersioning := jsonReqBody.ObjectOf("versioning") success = pObjVersioning.AddBoolAt(-1,"enabled",true) pObjVersioning.DisposeJsonObject() // Show the HTTP request body we'll be sending. fmt.Println(*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") jsonResponseStr := rest.FullRequestString("POST","/storage/v1/b",*jsonReqBody.Emit()) if rest.LastMethodSuccess() != true { fmt.Println(rest.LastErrorText()) gAuth.DisposeAuthGoogle() rest.DisposeRest() jsonReqBody.DisposeJsonObject() return } // Show the JSON response.
