(JavaScript) Google Translate Text
Demonstrates how to use the Cloud Translation API to translate text from one spoken language to another. The example translates from English to Spanish.
var success = false;
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// --------------------------------------------------------------------------------
// IMPORTANT:
// Don't forget you need to 1st enable the Cloud Translation API in your Google Developers Console at https://console.cloud.google.com
// --------------------------------------------------------------------------------
// It is assumed we previously obtained an OAuth2 access token.
// This example loads the JSON access token file
var jsonToken = new CkJsonObject();
success = jsonToken.LoadFile("qa_data/tokens/_googleTranslate.json");
if (success !== true) {
console.log("Failed to load _googleTranslate.json");
return;
}
var http = new CkHttp();
http.AuthToken = jsonToken.StringOf("access_token");
// The following JSON is sent in the request body.
// {
// "q": "The quick brown fox jumped over the lazy dog.",
// "source": "en",
// "target": "es",
// "format": "text"
// }
var json = new CkJsonObject();
// The following code creates the JSON request body.
json.UpdateString("q","The quick brown fox jumped over the lazy dog.");
json.UpdateString("source","en");
json.UpdateString("target","es");
json.UpdateString("format","text");
json.EmitCompact = false;
console.log(json.Emit());
var resp = new CkHttpResponse();
success = http.HttpJson("POST","https://translation.googleapis.com/language/translate/v2",json,"application/json",resp);
if (success == false) {
console.log(http.LastErrorText);
return;
}
var jResp = new CkJsonObject();
resp.GetBodyJson(jResp);
jResp.EmitCompact = false;
console.log("Response Body:");
console.log(jResp.Emit());
var respStatusCode = resp.StatusCode;
console.log("Response Status Code = " + respStatusCode);
if (respStatusCode >= 400) {
console.log("Response Header:");
console.log(resp.Header);
console.log("Failed.");
return;
}
// Sample JSON response:
// (Sample code for parsing the JSON response is shown below)
// {

// {
// "translatedText": "El zorro r�pida salt� sobre el perro perezoso."
// }
// ]
// }
