PHP发送post请求的三种方法

实现方法分为三种
为三种不同的函数实现

/** * 发送post请求
 * @param string $url 请求地址
 * @param array $post_data post键值对数据
 * @return string
 */

function send_post($url, $post_data)
{
    $postdata = http_build_query($post_data);
    $options = array(
        'http' => array(
            'method' => 'POST',
            'header' => 'Content-type:application/x-www-form-urlencoded',
            'content' => $postdata,
            'timeout' => 15 * 60 // 超时时间(单位:s)
        )
    );
    $context = stream_context_create($options);
    $result = file_get_contents($url, false, $context);
    return $result;
}

//使用方法
$post_data = array(
    'username' => 'stclair2201',
    'password' => 'handan'
);
send_post('http://localhost', $post_data);

/**
 * Socket版本
 * 使用方法:
 * $post_string = "app=socket&version=beta";
 * 吃猫的鱼 www.fish9.cn
 */
function request_by_socket($remote_server, $remote_path, $post_string, $port = 80, $timeout = 30)
{
    $socket = fsockopen($remote_server, $port, $errno, $errstr, $timeout);
    if (!$socket) die("$errstr($errno)");
    fwrite($socket, "POST $remote_path HTTP/1.0");
    fwrite($socket, "User-Agent: Socket Example");
    fwrite($socket, "HOST: $remote_server");
    fwrite($socket, "Content-type: application/x-www-form-urlencoded");
    fwrite($socket, "Content-length: " . (strlen($post_string) + 8) . "");
    fwrite($socket, "Accept:*/*");
    fwrite($socket, "");
    fwrite($socket, "mypost=$post_string");
    fwrite($socket, "");
    $header = "";
    while ($str = trim(fgets($socket, 4096))) {
        $header .= $str;
    }
    $data = "";
    while (!feof($socket)) {
        $data .= fgets($socket, 4096);
    }
    return $data;
}

/**
 * Curl版本
 * 使用方法:
 * $post_string = "app=request&version=beta";
 * 吃猫的鱼 www.fish9.cn
 */

function request_by_curl($remote_server, $post_string) {

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $remote_server);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'mypost=' . $post_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "jb51.net's CURL Example beta");
    $data = curl_exec($ch);
    curl_close($ch);
  
    return $data;
