Dart Requires Chilkat v11.0.0+

OneDrive -- Upload a String

See more OneDrive Examples

Uploads a string to the signed-in user's OneDrive. This uses OneDrive's simple upload API to upload in a single API call, which only supports uploads up to 4MB in size. (See the other example(s) for uploading larger files.) Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // This example uses the OAuth client credentials flow.
  // See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

  // Use your client ID, client secret, and tenant ID in the following lines
  final json = CkJsonObject();
  json.updateString('client_id', '2871da2c-8176-4b7f-869b-2311aa82e743');
  json.updateString('client_secret', '2hu9Q~r5QuryUcEkNbg1btLtnfU1VUXzhSCG6brH');
  json.updateString('scope', 'https://graph.microsoft.com/.default');
  json.updateString('token_endpoint', 'https://login.microsoftonline.com/114d7ed6-71bf-4dbe-a866-748364121bf2/oauth2/v2.0/token');

  final http = CkHttp();
  http.authToken = json.emit();

  // To upload in a single HTTP request, send a PUT request such as the following:

  // 	PUT /v1.0/users/{user_id}/drive/root:/{item-path}:/content
  // 	Content-type: text/plain
  // 	Content-Length: <the actual content length>
  // 
  // 	The contents of the file goes here.

  // Note: Chilkat automatically adds the Content-Length header.

  // This example will upload a string that happens to be XML.
  final someString = '<location><city>Chicago</city><state>IL</state></location>';

  // Upload to /TestDir/location.xml
  http.setUrlVar('dest_path', '/TestDir/location.xml');
  http.setUrlVar('user_id', '4fe732c3-322e-4a6b-b729-2fd1eb5c6104');
  final url = 'https://graph.microsoft.com/v1.0/users/{\$user_id}/drive/root:{\$dest_path}:/content';

  final resp = CkHttpResponse();
  try {
    http.httpStr('PUT', url, someString, 'utf-8', 'application/xml', resp);
  } on ChilkatException catch (e) {
