PHP implements the cross-domain request processing method of Baidu Wenxin Yiyan interface

When developing web applications, we often encounter the problem of cross-domain requests. Cross-domain requests refer to sending AJAX requests to different domain names in the browser. Due to the browser's same-origin policy restrictions, such cross-domain requests are blocked. To solve this problem, cross-domain requests can be implemented by processing them on the server side.

This article will introduce how to use PHP to implement cross-domain request processing for Baidu Wenxin Yiyan interface. Baidu Wenxin Yiyan interface is an API interface that provides random access to chicken soup for the soul.

First, we need to create a PHP file on the server side to handle cross-domain requests. Suppose we name this file baidu_wenxin.php and place it in the root directory of the server.

Next, we need to write PHP code to implement the request to Baidu Wenxin Yiyan interface. The specific code is as follows:

<?php
header('Content-Type: application/json');  // 设置响应头的Content-Type为json格式

// 获取百度文心一言接口的内容
$url = 'https://api.lovelive.tools/api/SweetNothings/';
$response = file_get_contents($url);

// 解析响应内容并以json格式返回
echo $response;
?>

In the above code, we first set the Content-Type of the response header to json format through the header() function to ensure that the returned data is presented in json format. Then use the file_get_contents() function to obtain the content from the Baidu Wenxin Yiyan interface and assign it to the $response variable. Finally, the response content is returned in json format through the echo statement.

In the client-side JavaScript code, we can call the server-side baidu_wenxin.php file through AJAX request to obtain Chicken Soup for the Soul. The specific code is as follows:

$.ajax({
  url: 'http://your_domain.com/baidu_wenxin.php',
  type: 'GET',
  dataType: 'json',
  success: function(response) {
    // 处理响应内容
    console.log(response);
  },
  error: function(jqXHR, textStatus, errorThrown) {
    // 处理错误
    console.log(textStatus, errorThrown);
  }
});

In the above code, we use jQuery's AJAX method to send cross-domain requests. By setting the url parameter to the server-side file path http://your_domain.com/baidu_wenxin.php, the type parameter is GET, The dataType parameter is json to specify the target and data type of the request. In the success callback function, we can handle the returned chicken soup data; in the error callback function, we can handle the error situation.

In actual deployment, you need to replace http://your_domain.com with your server domain name or IP address.

Through the above steps, we successfully implemented cross-domain request processing for Baidu Wenxin Yiyan interface. According to the above method, you can also implement cross-domain request processing for other API interfaces.

Summary:

This article introduces how to use PHP to implement cross-domain request processing for Baidu Wenxin Yiyan interface. By creating a PHP file on the server side to handle cross-domain requests, and using the AJAX method to call the file on the client side, we can easily achieve access to Baidu Wenxin Yiyan interface. This method can be widely used in cross-domain request processing of other API interfaces and brings convenience to web development.
