PHP code implements CORS cross-domain processing of response results of Baidu Wenxin Yiyan API interface

In Web development, cross-Origin Resource Sharing ) is a common question. When we request resources under one domain name from a web page under another domain name, if cross-domain processing is not performed, the browser will block the request by default. In actual development, we often need to call third-party interfaces in the front-end page to obtain data. This article will introduce how to use PHP code to implement CORS cross-domain processing of the response results of Baidu Wenxinyiyan API interface.

The Baidu Wenxin Yiyan API interface is an interface that provides random sentences. We can obtain a random Wenxin Yiyan by sending a GET request to the interface. First, we need to use XMLHttpRequest or Fetch API in the front-end page to send a GET request to the Baidu Wenxin Yiyan API interface. Due to the browser's same-origin policy, we need to perform CORS cross-domain processing on the server side.

The following is a simple PHP code example that demonstrates how to implement CORS cross-domain processing of the response results of Baidu Wenxin Yiyan API interface:

<?php
// 百度文心一言 API 接口地址
$url = 'https://v1.hitokoto.cn/';

// 使用 CURL 发送 GET 请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// 设置请求头中的 Origin 字段，用于解决 CORS 跨域问题
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Origin: https://your-domain.com', // 将 your-domain.com 替换为你实际的域名
]);

$response = curl_exec($ch);
curl_close($ch);

// 设置响应头中的 Access-Control-Allow-Origin 字段，允许跨域访问
header('Access-Control-Allow-Origin: https://your-domain.com');
// 其他 CORS 相关响应头可以根据需要进行设置

// 输出 API 响应结果
echo $response;
?>

In the above code, we first Define the address of Baidu Wenxin Yiyan API interface, and then use CURL to send a GET request to the interface. The Origin field is set in the request header, and its value is the domain name where our front-end page is located. Next, we read the data from the API response and output it. Finally, set the Access-Control-Allow-Origin field in the response header to the domain name of our front-end page to allow cross-domain access.

It should be noted that in the above code, we set the values ​​of the Origin field and the Access-Control-Allow-Origin field to the domain name where our front-end page is located. You need to replace "https://your-domain.com" in the code with your actual domain name.

Through the above code example, we can implement CORS cross-domain processing of the response results of Baidu Wenxinyiyan API interface on the PHP server side. In this way, we can call this interface in the front-end page to obtain the data of random sentences. Everyone can make corresponding modifications and expansions according to their actual needs.

Summary:
This article demonstrates how to implement CORS cross-domain processing of the response results of Baidu Wenxinyiyan API interface through PHP code examples. In actual development, for cross-domain issues, we need to handle them on the server side to ensure that the front-end page can normally obtain data from the third-party interface. I hope this article can help everyone solve the problem of cross-domain requests.
