php获取curl头_php中CURL请求头和响应头获取方法

在有的时候，我们需要通过获取接口相应的请求头信息，可以在curl_exec函数执行前，添加代码

curl_setopt($ch,CURLINFO_HEADER_OUT,true);

然后在curl_exec函数执行后，通过 curl_getinfo($ch,CURLINFO_HEADER_OUT) 来获取curl执行请求的请求数据

直接上代码：

public static function httpRequest($url, $method = 'GET', $params = null, $headers = array(), $pem = array(), $debug = false, $timeout = 60) {        $method = strtoupper($method);        $ci = curl_init();                curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);        curl_setopt($ci, CURLOPT_USERAGENT, 'Google/5.0 (Windows NT 11.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36');        // curl_setopt($ci, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);        curl_setopt($ci, CURLOPT_CONNECTTIMEOUT, $timeout);        curl_setopt($ci, CURLOPT_RETURNTRANSFER, TRUE);        curl_setopt($ci, CURLOPT_POST, TRUE);        if(!empty($params)) {           $tmpdatastr = is_array($params) ? http_build_query($params) : $params;           curl_setopt($ci, CURLOPT_POSTFIELDS, $tmpdatastr);        }        curl_setopt($ci, CURLOPT_URL, $url);        curl_setopt($ci, CURLOPT_MAXREDIRS, 2);        curl_setopt($ci, CURLOPT_HTTPHEADER, $headers);        curl_setopt($ci, CURLINFO_HEADER_OUT, true);        curl_setopt($ci , CURLOPT_HEADER, true );        $response = curl_exec($ci);        $requestinfo = curl_getinfo($ci);        $http_code = curl_getinfo($ci, CURLINFO_HTTP_CODE);        $headerSize = curl_getinfo($ci , CURLINFO_HEADER_SIZE);        $headerStr = substr( $response , 0 , $headerSize );        $bodyStr = substr( $response , $headerSize );        $responseHeader = self::headerHandler($headerStr);        yii::info('响应header信息'.json_encode($responseHeader), 'app');        yii::info('响应body信息'.$bodyStr, 'app');        if($debug) {            echo "=====post data======\r\n";            var_dump($params);            echo "=====info===== \r\n";            print_r($requestinfo);            echo "=====response=====\r\n";            print_r($response);        }        curl_close($ci);        return $bodyStr;    }   public static function headerHandler($str) {        $headers = array();        $headersTmpArray = explode("\r\n", $str);        for($i = 0; $i < count($headersTmpArray); ++$i) {            if(strlen($headersTmpArray[$i]) > 0) {                if(strpos($headersTmpArray[$i], ':')) {                    $headerName = substr($headersTmpArray[$i], 0, strpos($headersTmpArray[$i], ':'));                    $headerValue = substr($headersTmpArray[$i], strpos($headersTmpArray[$i], ':') + 1);                    $headers[$headerName] = $headerValue;                }            }        }        return $headers;    }

看一下结果：

这个是响应头的信息：

可以看到里面可以设置一些请求id之类的东西。
