(JavaScript) Upload Application Specific Data

Uploads a text file (application specific data) where the contents of the file are contained in a string variable.

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;

success = true;

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

// This example uses a previously obtained access token having permission for the 
// Google Drive application specific data scope.
var jsonToken = new CkJsonObject();
success = jsonToken.LoadFile("qa_data/tokens/googleDriveAppData.json");

var gAuth = new CkAuthGoogle();
gAuth.AccessToken = jsonToken.StringOf("access_token");

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 token)
rest.SetAuthGoogle(gAuth);

// A multipart upload to Google Drive needs a multipart/related Content-Type
rest.AddHeader("Content-Type","multipart/related");

// Specify each part of the request.

// The 1st part is JSON with information about the file.
rest.PartSelector = "1";
rest.AddHeader("Content-Type","application/json; charset=UTF-8");

var json = new CkJsonObject();
json.EmitCompact = false;

json.UpdateString("name","helloWorld.txt");
json.UpdateString("description","A simple text file that says Hello World.");
json.UpdateString("mimeType","text/plain");
// Specifiy the application-specific data folder.
json.UpdateString("parents[0]","appDataFolder");
rest.SetMultipartBodyString(json.Emit());

console.log(json.Emit());

// The JSON looks like this:
// {
//   "name": "helloWorld.txt",
//   "description": "A simple text file that says Hello World.",
//   "mimeType": "text/plain",
//   "parents": [
//     "appDataFolder"
//   ]
// }

// The 2nd part is the file content.
// In this case, we'll upload a simple text file containing "Hello World!"
rest.PartSelector = "2";
rest.AddHeader("Content-Type","text/plain");

var fileContents = "Hello World!";
rest.SetMultipartBodyString(fileContents);

var jsonResponse = rest.FullRequestMultipart("POST","/upload/drive/v3/files?uploadType=multipart");
if (rest.LastMethodSuccess !== true) {
    console.log(rest.LastErrorText);
    return;
}

// A successful response will have a status code equal to 200.
if (rest.ResponseStatusCode !== 200) {
    console.log("response status code = " + rest.ResponseStatusCode);
    console.log("response status text = " + rest.ResponseStatusText);
    console.log("response header: " + rest.ResponseHeader);
    console.log("response JSON: " + jsonResponse);
    return;
}

// Show the JSON response.
json.Load(jsonResponse);

// Show the full JSON response.
json.EmitCompact = false;
console.log(json.Emit());

// A successful response looks like this:
// {
//   "kind": "drive#file",
//   "id": "0B53Q6OSTWYoldmJ0Z3ZqT2x5MFk",
//   "name": "Untitled",
//   "mimeType": "text/plain"
// }

// Get the fileId:
console.log("fileId: " + json.StringOf("id"));
