# Issue Network Requests

## Using `fetch` to Make Network Requests <a href="#vrr9c" id="vrr9c"></a>

The `fetch` function is a tool for accessing network resources, allowing you to send HTTP requests and handle response processing. The `fetch` function supports many different types of requests, including `GET`, `POST`, `PUT`, and `DELETE`, and supports custom formats for request and response bodies.

By using the `fetch` function, you can easily access network resources and control the request and response process. For example, you can use the following code to send a `GET` request and process the response after the request is fulfilled:

```javascript
fetch('https://example.com/api/endpoint')
    .then(response => response.json())
    .then(data => {
    	// Process the response here
    });
```

This example code sends a GET request to the specified network resource, then parses the response body into JSON format after the request is completed, and processes the parsed response body here.

## Using `https` to Make Requests <a href="#oowx7" id="oowx7"></a>

Due to the default security limitations of browsers, the `fetch` method sometimes encounters some restrictions. In this case, we can switch to using Node.js native networking APIs to send network requests for greater flexibility.

Sending an HTTP GET request using the `https.get` method is very simple; you only need to provide the URL of the request. For example, you can use the following code to send an HTTP GET request:

```javascript
const https = require('https');

https.get('https://www.example.com', (res) => {
  console.log(`Got response: ${res.statusCode}`);

  res.on('data', (d) => {
    // Process response data
  });

}).on('error', (e) => {
  console.error(`Got error: ${e.message}`);
});
```
