How to use methods to execute multiple requests in parallel

Use the() method to execute multiple requests in parallel

In Vue, multiple requests can be executed in parallel using the() method.

When multiple asynchronous requests need to be executed simultaneously, these requests can be encapsulated as Promise objects and executed using the() method.

Example 1

Here is a sample code that shows how to execute multiple requests in parallel through the() method:

//Define multiple requestsconst request1 = ('/api/data1');
const request2 = ('/api/data2');
const request3 = ('/api/data3');

//Execute multiple requests using the() method([request1, request2, request3])
  .then(function (results) {
    //results contains the results of all requests    const data1 = results[0].data;
    const data2 = results[1].data;
    const data3 = results[2].data;
    //TODO processing request result  })
  .catch(function (error) {
    //TODO handles request error  });

In the above example, three requests are defined: request1, request2, and request3.

Then, use the() method to execute these requests. When all requests are returned successfully, the () method returns an array containing all request results. The result of each request can be obtained through array indexing.

If any of the requests fail, the () method will immediately trigger the catch() method and return an error message.

This way of executing multiple requests in parallel can significantly improve the performance and response speed of the program. Because multiple requests can be made simultaneously, there is no need to wait for each request to complete before the next request is executed.

Example 2

let [res1, res2] = await ([
	request({
	  url: '/api/data1',
	  method: 'get',
	  params: params1
	}),
	request({
	  url: '/api/data2',
	  method: 'get',
	  params: params2
	})
]);
('res1',res1,'res2',res2);
