项目效果预览

1. 准备工作

• PHP环境：确保你的开发环境中安装了PHP。
• DeepSeek API密钥：注册并获取DeepSeek API的访问密钥。

2. 创建PHP文件，编写API调用脚本

创建一个PHP脚本（api.php），用于调用DeepSeek API。假设API密钥为YOUR_API_KEY。

<?php
header('Content-Type: application/json');

function callDeepSeekAPI($message) {
   
   
    $apiKey = 'YOUR_API_KEY';
    $url = 'https://api.deepseek.com/chat/completions';

    $data = [
        "model" => "deepseek-chat",
        'messages' => [
            ["role" => "system", "content" => "You are a helpful assistant."],
            ["role" => "user", "content" => $message]
        ],
        'stream'=>false
    ];

    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_HTTPHEADER, [
        'Content-Type: application/json',
        'Authorization: Bearer ' . $apiKey
    ]);

    $response = curl_exec($ch);
    if (curl_errno($ch)) {
   
   
        $error_msg = curl_error($ch);
        curl_close(
