前言

最近自己做了团队内部的http调试工具，github开源地址 https://github.com/diandianxiyu/ApiTesting ，通过这个项目又重新操作了PHP的curl函数，通过本篇博客进行记录，和大家一起学习~

Code

本代码通过PHP7环境运行。

function curl($url, $method='GET',$fields = [], $headers=[],$auth = false){        //如果是get的获取方式，拼接参数到url上        if($method == "GET"){            $fields_string = http_build_query($fields);            $url=$url."?".$fields_string;        }        $curl = curl_init($url); //初始化        curl_setopt ($curl, CURLOPT_CUSTOMREQUEST, $method ); //设定HTTP请求方式        curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($curl, CURLOPT_VERBOSE, 1);        curl_setopt($curl, CURLOPT_HEADER, 1);        $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,";        $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5";        $header[] = "Cache-Control: max-age=0";        $header[] = "Connection: keep-alive";        $header[] = "Keep-Alive: 300";        $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7";        $header[] = "Accept-Language: en-us,en;q=0.5";        $header[] = "Pragma: "; // browsers keep this blank.        curl_setopt($curl, CURLOPT_HTTPHEADER, array_merge($header,$headers)); //和参数中的header一起传递过去        if($auth){            curl_setopt($curl, CURLOPT_USERPWD, "$auth");            curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);        }        if($fields){            //POST            if($method == "POST"){//单独对POST方法设置参数传递                $fields_string = http_build_query($fields);                curl_setopt($curl, CURLOPT_POST, true);                curl_setopt($curl, CURLOPT_BINARYTRANSFER, true);                curl_setopt($curl, CURLOPT_POSTFIELDS, $fields_string);            }else{                curl_setopt($curl, CURLOPT_RETURNTRANSFER, true) ;                curl_setopt($curl, CURLOPT_BINARYTRANSFER, true) ;            }        }        $response = curl_exec($curl); //执行curl        $header_size = curl_getinfo($curl, CURLINFO_HEADER_SIZE);        $header_string = substr($response, 0, $header_size);        $body = substr($response, $header_size);        $header_rows = explode(PHP_EOL, $header_string);        foreach($header_rows as $key => $value){            $header_rows[$key]=trim($header_rows[$key]);        }        $i=0;        foreach((array)$header_rows as $hr){            $colonpos = strpos($hr, ':');            $key = $colonpos !== false ? substr($hr, 0, $colonpos) : (int)$i++;            $headers[$key] = $colonpos !== false ? trim(substr($hr, $colonpos+1)) : $hr;        }        $j=0;        foreach((array)$headers as $key => $val){            $vals = explode(';', $val);            if(count($vals) >= 2){                unset($headers[$key]);                foreach($vals as $vk => $vv){                    $equalpos = strpos($vv, '=');                    $vkey = $equalpos !== false ? trim(substr($vv, 0, $equalpos)) : (int)$j++;                    $headers[$key][$vkey] = $equalpos !== false ? trim(substr($vv, $equalpos+1)) : $vv;                }            }        }        curl_close($curl);        return array($body, $headers); //最终返回 result[0]为body,result[1]为header    }
