CURL 封装好的请求方法


//可以发送https,http,get方式,post方式  post数据发送
function request($url, $https = true, $method = 'get', $data = null)
{
    //1.初始化curl
    $ch = curl_init($url);
    //2.设置相关的参数
    //字符串不直接输出,进行一个变量的存储
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    // curl_setopt($ch, CURLOPT_HEADER, 1);
    //判断是否为https请求
    if ($https === true) {
        //为了确保https请求能够请求成功
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    }
    //判断是否为post请求
    if ($method == 'post') {
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    }
    //3.发送请求
    $str = curl_exec($ch);
    // $hd = curl_getinfo($ch);
    //4.关闭连接
    curl_close($ch);
    //返回请求到的结果
    // return array('str'=>$str,'hd'=>$hd);
    return $str;
