本文介绍了PHP Curl 请求不起作用，但在 POSTMAN 中工作正常的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试登录 MCA 门户(POST URL:

知道缺少什么吗?

解决方案

网站做了重定向，所以需要添加

CURLOPT_FOLLOWLOCATION =>1

到您的选项数组.如果对 cURL 有疑问，请尝试

$status = curl_getinfo($curl);echo json_encode($status, JSON_PRETTY_PRINT);

给予:

{"url": "www.mca.gov.in/mcafoportal/loginValidateUser.do?userNamedenc=hGJfsdnk%601t&passwordenc=675894242fa9c66939d9fcf4d5c39d1830f4ddb9&accessCode=-825374456","content_type": "text/plain",http_code":302，header_size":1560，请求大小":245，文件时间":-1，ssl_verify_result":0，重定向计数":0，总时间":1.298891，名称查找时间":0.526375，连接时间":0.999786，pretransfer_time":0.999844，大小上传":0，大小下载":0，速度下载":0，速度上传":0，下载内容长度":0，上传内容长度":-1，starttransfer_time":1.298875，重定向时间":0，"redirect_url": "www.mca.gov.in/mcafoportal/login.do","primary_ip": "115.114.108.120",证书信息":[]，primary_port":80，"local_ip": "192.168.1.54",本地端口":62524}

如您所见，您获得了 302 重定向状态，但 redirect_count 为 0.添加选项后，我得到:

{"url": "www.mca.gov.in/mcafoportal/login.do","content_type": "text/html;charset=ISO-8859-1",http_code":200，header_size":3131，请求大小":376，文件时间":-1，ssl_verify_result":0，重定向计数":1，总时间":2.383609，名称查找时间":1.7e-5，连接时间":1.7e-5，pretransfer_time":4.4e-5，大小上传":0，大小下载":42380，速度下载":17779，速度上传":0，下载内容长度":42380，上传内容长度":-1，starttransfer_time":0.30734，重定向时间":0.915858，"redirect_url": "","primary_ip": "14.140.191.120",证书信息":[]，primary_port":80，"local_ip": "192.168.1.54",本地端口":62642}

EDIT url 编码请求参数，并遵循重定向

$str = urlencode("userNamedenc=hGJfsdnk%601t&passwordenc=675894242fa9c66939d9fcf4d5c39d1830f4ddb9&accessCode=-825374456");curl_setopt_array($curl , 数组 (CURLOPT_URL =>"www.mca.gov.in/mcafoportal/loginValidateUser.do" ,//<- 此处删除参数CURLOPT_RETURNTRANSFER =>真的 ，CURLOPT_ENCODING =>"",CURLOPT_FOLLOWLOCATION =>1、CURLOPT_MAXREDIRS =>10、CURLOPT_TIMEOUT =>30 ,CURLOPT_HTTP_VERSION =>CURL_HTTP_VERSION_1_1 ,CURLOPT_CUSTOMREQUEST =>邮政" ，CURLOPT_POSTFIELDS =>$str,//<- 在此处添加CURLOPT_HTTPHEADER =>大批 (缓存控制:无缓存") ,));

I am trying to login to MCA portal ( POST URL : www.mca.gov.in/mcafoportal/loginValidateUser.do )

I tried logging in with POSTMAN app on Google Chrome which works fine. However, it doesnt work either in PHP/Python. I am not able to login through PHP/Python

Here is the PHP Code :

$url="www.mca.gov.in/mcafoportal/loginValidateUser.do"; $post_fields = array(); $post_fields['userNamedenc']='hGJfsdnk`1t'; $post_fields['passwordenc']='675894242fa9c66939d9fcf4d5c39d1830f4ddb9'; $post_fields['accessCode'] = "" $str = call_post_mca($url, $post_fields); $str = str_replace("&nbsp;","",$str); $dom = new DOMDocument(); $dom->loadHTML($str); $xpath = new DOMXPath($dom); $input_id = '//input[@id="login_accessCode"]/@value'; $input_val = $xpath->query($input_id)->item(0); $input_val1 = $input_val->nodeValue; $url="www.mca.gov.in/mcafoportal/loginValidateUser.do"; $post_fields['userNamedenc']='hGJfsdnk`1t'; $post_fields['passwordenc']='675894242fa9c66939d9fcf4d5c39d1830f4ddb9'; $post_fields['accessCode'] = $input_val1; //New Accesscode function call_post_mca($url, $params) { #$user_agent = getRandomUserAgent(); $user_agent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36"; $str = ""; foreach($params as $key=>$value) { $str = $str . "$key=$value" . "&"; } $postData = rtrim($str, "&"); $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); curl_setopt($ch,CURLOPT_HEADER, false); #curl_setopt($ch, CURLOPT_CAINFO, DOC_ROOT . '/includes/cacert.pem'); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); curl_setopt($ch,CURLOPT_USERAGENT, $user_agent); curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt ($ch, CURLOPT_REFERER, $url); $cookie= DOC_ROOT . "/cookie.txt"; curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); curl_setopt ($ch, CURLOPT_COOKIEFILE, $cookie); $output=curl_exec($ch); curl_close($ch); return $output; }

Any idea what is missing ?

解决方案

The site does a redirect, so you need to add

CURLOPT_FOLLOWLOCATION => 1

to your options array. When in doubt with cURL, try

$status = curl_getinfo($curl); echo json_encode($status, JSON_PRETTY_PRINT);

giving :

{ "url": "www.mca.gov.in/mcafoportal/loginValidateUser.do?userNamedenc=hGJfsdnk%601t&passwordenc=675894242fa9c66939d9fcf4d5c39d1830f4ddb9&accessCode=-825374456", "content_type": "text/plain", "http_code": 302, "header_size": 1560, "request_size": 245, "filetime": -1, "ssl_verify_result": 0, "redirect_count": 0, "total_time": 1.298891, "namelookup_time": 0.526375, "connect_time": 0.999786, "pretransfer_time": 0.999844, "size_upload": 0, "size_download": 0, "speed_download": 0, "speed_upload": 0, "download_content_length": 0, "upload_content_length": -1, "starttransfer_time": 1.298875, "redirect_time": 0, "redirect_url": "www.mca.gov.in/mcafoportal/login.do", "primary_ip": "115.114.108.120", "certinfo": [], "primary_port": 80, "local_ip": "192.168.1.54", "local_port": 62524 }

As you can see, you got a 302 redirect status, but a redirect_count was 0. After adding the option, i get:

{ "url": "www.mca.gov.in/mcafoportal/login.do", "content_type": "text/html;charset=ISO-8859-1", "http_code": 200, "header_size": 3131, "request_size": 376, "filetime": -1, "ssl_verify_result": 0, "redirect_count": 1, "total_time": 2.383609, "namelookup_time": 1.7e-5, "connect_time": 1.7e-5, "pretransfer_time": 4.4e-5, "size_upload": 0, "size_download": 42380, "speed_download": 17779, "speed_upload": 0, "download_content_length": 42380, "upload_content_length": -1, "starttransfer_time": 0.30734, "redirect_time": 0.915858, "redirect_url": "", "primary_ip": "14.140.191.120", "certinfo": [], "primary_port": 80, "local_ip": "192.168.1.54", "local_port": 62642 }

EDIT url encode the request parameters , and follow redirects

$str = urlencode("userNamedenc=hGJfsdnk%601t&passwordenc=675894242fa9c66939d9fcf4d5c39d1830f4ddb9&accessCode=-825374456"); curl_setopt_array( $curl , array ( CURLOPT_URL => "www.mca.gov.in/mcafoportal/loginValidateUser.do" , // <- removed parameters here CURLOPT_RETURNTRANSFER => true , CURLOPT_ENCODING => "" , CURLOPT_FOLLOWLOCATION => 1 , CURLOPT_MAXREDIRS => 10 , CURLOPT_TIMEOUT => 30 , CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1 , CURLOPT_CUSTOMREQUEST => "POST" , CURLOPT_POSTFIELDS => $str, // <- added this here CURLOPT_HTTPHEADER => array ( "cache-control: no-cache" ) , ) );
