Sample Code

The following code demonstrates how to retrieve video information.

<!DOCTYPE html>​
<html lang="en">​
  <head>​
    <meta charset="UTF-8" />​
    <title>Get video information</title>​
  </head>​
​
  <body>​
    <div>Please see console for more information</div>​

        accessKeySecret: 'yourAccessKeySecret',​
        stsToken: 'yourSecurityToken',​
      });​
​
      function handleError(error) {​
        if (error instanceof TosClientError) {​
