PHP http请求封装使用(POST.GET,PUT,DELETE)

封装的 sendRequest() 函数是一个通用的发送请求函数，可以发送 POST、GET、PUT、DELETE 请求。下面对该函数的代码进行具体讲解： 

"multipart/form-data",2=>"application/json",3=>"application/x-www-form-urlencoded"];
        $contentType=$contentTypeArr[$contentType];
    }
    // 创建一个 cURL 资源
    $curl = curl_init($url);
    // 判断是否为 HTTPS 请求
    if (stripos($url, "https://") !== false) {
        // 设置 SSL 选项
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 不验证证书
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); // 不验证主机名
        curl_setopt($curl, CURLOPT_SSLVERSION, 1); // 使用 TLSv1 协议
    }
    // 根据请求方法设置 cURL 选项
    switch ($method) {
        case 'POST':
            curl_setopt($curl, CURLOPT_POST, true);
            break;
        case 'GET':
            curl_setopt($curl, CURLOPT_HTTPGET, true);
            break;
        case 'PUT':
            $contentType = 'application/json';
            curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'PUT');
            break;
        case 'DELETE':
            $contentType = 'application/json';
            curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'DELETE');
            break;
    }
    // 设置 cURL 选项
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
    // 设置请求头
    $headers[] = 'Content-Type: ' . $contentType;
    if (!empty($headers)) {
        curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    }
    // 根据编码格式设置请求参数
    if ($data !== null) {
        if ($contentType == 'application/json') {
            $postData = json_encode($data);
        } elseif ($contentType == 'multipart/form-data') {
            $postData = $data;
        } elseif ($contentType == 'application/x-www-form-urlencoded') {
            $postData = http_build_query($data);
        }

        curl_setopt($curl, CURLOPT_POSTFIELDS, $postData);
    }
    // 发送请求并获取响应

    $response = curl_exec($curl);
    // 检查是否有错误发生
    if ($response === false) {
        $error = curl_error($curl);
        // 处理错误信息
    } else {
        // 处理响应数据
    }
    // 关闭 cURL 资源
    curl_close($curl);
    // 返回响应数据
    return $response;
}

1、 POST 请求示例

$data = array(
    'field1' => 'value1',
    'field2' => 'value2'
);
$headers = array(
    'Authorization: Bearer token'
);
$url='xxx.com/test.php';
$response = sendRequest('POST', $url, $data, 1, $headers, 60);
var_dump($response);

接收方式

var_dump($_POST);

2、GET 请求示例

$url='xxx.com/test.php?a=1';
$response = sendRequest('GET', $url);
var_dump($response);

接收方式

var_dump($_GET);

3、PUT 请求示例

$data = array(
    'field1' => 'value1',
    'field2' => 'value2'
);
$url='xxx.com/test.php';
$response = sendRequest('PUT', $url, $data);

接收方式

var_dump(json_decode(file_get_contents('php://input'),true));

4、DELETE 请求示例

$data = array(
    'field1' => 'value1',
    'field2' => 'value2'
);
$url='xxx.com/test.php';
$response = sendRequest('DELETE', $url, $data);

接收方式

var_dump(json_decode(file_get_contents('php://input'),true));
