Upload Files to a Web Server - Simplest Example

See more Upload Examples

This is the simplest example for uploading some files to a web server. the BlockingUpload call is synchronous and returns when the upload is finished (or failed).

A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload

React Native

import { Upload } from '@chilkat/react-native'

async function chilkatExample() {
  const upload = new Upload();

  // Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
  // that will receive and process the HTTP Upload.
  upload.hostname = 'www.mywebserver.com';
  upload.path = '/receiveUpload.aspx';

  // Add one or more files to be uploaded.
  upload.addFileReference('file1', 'dude.gif');
  upload.addFileReference('file2', 'swordfish.xml');
  upload.addFileReference('file3', 'sample.doc');

  // Do the upload.  The method returns when the upload
  // is completed.
  // This component also includes asynchronous upload capability,
  // which is demonstrated in another example.
  try {
    await upload.blockingUploadAsync();
    console.log('Files uploaded!');
  } catch {
    console.log(upload.lastErrorText);
  }
}
