PHP调用API接口的几种方法

$url = "https://api.example.com/users/1";

// 初始化cURL
$ch = curl_init();

// 设置请求选项
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  // 不直接输出结果
curl_setopt($ch, CURLOPT_TIMEOUT, 30);          // 请求超时时间
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Content-Type: application/json',
    'Authorization: Bearer your-access-token'   // 如果需要认证
]);

// 执行请求
$response = curl_exec($ch);

// 检查是否有错误
if (curl_error($ch)) {
    die("请求出错: " . curl_error($ch));
}

// 关闭cURL
curl_close($ch);

// 解析JSON响应
$data = json_decode($response, true);

// 使用数据
if ($data) {
    echo "用户名: " . $data['name'];
} else {
    echo "无法解析数据";
}

$url = "https://api.example.com/login";
$postData = [
    'username' => 'testuser',
    'password' => 'testpass'
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($postData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Content-Type: application/json',
    'Accept: application/json'
]);

$response = curl_exec($ch);

if (curl_error($ch)) {
    die("请求失败: " . curl_error($ch));
}

curl_close($ch);

$result = json_decode($response, true);
print_r($result);
