The Get Video Information function can obtain meta information for a specified video resource. This article describes how to obtain video information through the TOS Node.js SDK.

Sample code

The following code shows how to obtain video information.

// Import SDK, if the TOS Node.JS SDK version is less than 2.5.2, please change "TosClient" to "TOS" in the code below.​
import { TosClient, TosClientError, TosServerError } from '@volcengine/tos-sdk';​
​
// Create a client.​
const client = new TosClient({​
  accessKeyId: process.env['TOS_ACCESS_KEY'],​
  accessKeySecret: process.env['TOS_SECRET_KEY'],​
  region: "Provide your region", // Fill in the region where the Bucket is located. For example, if it is in China North 2 (Beijing), fill in "Provide your region" as cn-beijing.​
  endpoint: "Provide your endpoint", // Enter the domain address.​
});​
​
function handleError(error) {​
  if (error instanceof TosClientError) {​
    console.log('Client Err Msg:', error.message);​
    console.log('Client Err Stack:', error.stack);​
  } else if (error instanceof TosServerError) {​
    console.log('Request ID:', error.requestId);​
    console.log('Response Status Code:', error.statusCode);​
    console.log('Response Header:', error.headers);​
    console.log('Response Err Code:', error.code);​
    console.log('Response Err Msg:', error.message);​
  } else {​
    console.log('unexpected exception, message: ', error);​
  }​
}​
​
const bucketName = 'node-sdk-test-bucket';​
async function main() {​
  try {​
    // Video Title​
    const videoKey = 'video.mp4';​
​
    const style = 'video/info'; /* Get video information. */​
    const { data, requestId, headers } = await client.getObjectV2({​
      bucket: bucketName,​
      key: videoKey,​
      dataType: 'buffer',​
      process: style,​
    });​
    console.log('getObjectV2 Request ID: ', requestId);​
    console.log('ContentType: ', headers['content-type']);​
​
    const info = JSON.parse(data.content.toString());​
    console.log('info: %o', info);​
  } catch (error) {​
    handleError(error);​
  }​
}​
​
main();​
