POST请求

function httpPost($url,$data){ // 模拟提交数据函数
    $curl = curl_init(); // 启动一个CURL会话
    curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 禁用对认证证书来源的检查
    curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // 模拟用户使用的浏览器
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转
    curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer
    curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Post提交的数据包
//    curl_setopt($curl, CURLOPT_COOKIEFILE, $GLOBALS['cookie_file']); // 读取上面所储存的Cookie信息
    curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循环
    curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回
    $res = curl_exec($curl); // 执行操作
    if (curl_errno($curl)) {
        echo 'Errno'.curl_error($curl);
    }
    url_close($curl); // 关键CURL会话
    return $res; // 返回数据
}

GET请求

function httpGet($url) {
    header("Content-Type:text/html;charset=UTF-8");
    $curl = curl_init();
    curl_setopt($curl,CURLOPT_HTTPHEADER,array (
        "Content-Type: text/xml; charset=utf-8"
    ));
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_TIMEOUT, 500);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($curl, CURLOPT_URL, $url);
    $res = curl_exec($curl);
    curl_close($curl);
    return $res;
}

file_get_contents实现GET请求

function httpGet($url){
    $res = file_get_contents($url);
    $res = json_decode($s, true);
    return $res;
}
