PHP を使用して Baidu Smart Writing API に接続するコードを記述する方法

<?php

// 设置请求参数
$apiKey = '你的API Key';
$secretKey = '你的Secret Key';
$url = 'https://aip.baidubce.com/oauth/2.0/token';
$params = array(
    'grant_type' => 'client_credentials',
    'client_id' => $apiKey,
    'client_secret' => $secretKey
);

// 获取 access_token
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
$result = curl_exec($ch);
curl_close($ch);

$access_token = json_decode($result)->access_token;

// 使用 access_token 调用智能写作 API
$url = 'https://aip.baidubce.com/rpc/2.0/creation/v1/article';
$headers = array(
    'Content-Type: application/json',
    'Authorization: Bearer ' . $access_token
);
$data = array(
    'type' => 0,  // 生成文章的类型，0代表通用型
    'title' => '这是生成的文章标题',
    'content' => '这是生成的文章内容'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
$result = curl_exec($ch);
curl_close($ch);

// 处理返回结果
$article = json_decode($result)->article;

// 输出生成的文章
echo $article;
