This article mainly introduces the encapsulated php cUrl request function, which has certain reference value. Now I share it with everyone. Friends in need can refer to it

After turning on debugging mode

##Usage:

$params = [
    &#39;name&#39;=>&#39;name&#39;
    ];
$url = &#39;&#39;;
httpRequest($url,&#39;POST&#39;,$params,[],true);

/**
 * CURL请求
 * @param $url 请求url地址
 * @param $method 请求方法 get post
 * @param null $postfields post数据数组
 * @param array $headers 请求header信息
 * @param bool|false $debug 调试开启 默认false
 * @return mixed
 */
function httpRequest($url, $method = "GET", $postfields = null, $headers = array(), $debug = false)
{
    $method = strtoupper($method);
    $ci = curl_init();
    /* Curl settings */
    curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);//版本
    curl_setopt($ci, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0");//在HTTP请求中包含一个"User-Agent: "头的字符串。
    curl_setopt($ci, CURLOPT_CONNECTTIMEOUT, 60); /* 在发起连接前等待的时间，如果设置为0，则无限等待 */
    curl_setopt($ci, CURLOPT_TIMEOUT, 7); /* 设置cURL允许执行的最长秒数 */
    curl_setopt($ci, CURLOPT_RETURNTRANSFER, true);//将curl_exec()获取的信息以文件流的形式返回，而不是直接输出。
    switch ($method) {
        case "POST":
            curl_setopt($ci, CURLOPT_POST, true);//启用时会发送一个常规的POST请求，类型为：application/x-www-form-urlencoded，就像表单提交的一样。
            if (!empty($postfields)) {
                $tmpdatastr = is_array($postfields) ? http_build_query($postfields) : $postfields;
                curl_setopt($ci, CURLOPT_POSTFIELDS, $tmpdatastr);
            }
            break;
        default:

    }
    $ssl = preg_match(&#39;/^https:\/\//i&#39;, $url) ? TRUE : FALSE;

    if ($ssl) {

        curl_setopt($ci, CURLOPT_SSL_VERIFYHOST, FALSE); // 不从证书中检查SSL加密算法是否存在
    }
    //curl_setopt($ci, CURLOPT_HEADER, true); /*启用时会将头文件的信息作为数据流输出*/
    curl_setopt($ci, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ci, CURLOPT_MAXREDIRS, 2);/*指定最多的HTTP重定向的数量，这个选项是和CURLOPT_FOLLOWLOCATION一起使用的*/
    curl_setopt($ci, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ci, CURLINFO_HEADER_OUT, true);
    /*curl_setopt($ci, CURLOPT_COOKIE, $Cookiestr); * *COOKIE带过去** */
