PHP Curl请求不起作用，但在POSTMAN中可以正常工作

本文介绍了PHP Curl请求不起作用，但在POSTMAN中可以正常工作的处理方法，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：

任何想法都丢失了吗？

解决方案

该站点进行重定向，因此您需要添加

CURLOPT_FOLLOWLOCATION => 1

到您的期权数组。如果对cURL有疑问，请尝试

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

给予：

{ url： http：\ / \ / www.mca.gov.in\ / mcafoportal\ / loginValidateUser.do？userNamedenc = hGJfsdnk％601t& passwordenc = 675894242fa9c66939d9fcf4d5c39d1830f4ddb9& ; accessCode = -825374456， content_type：文本\ /普通， 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： http：\ / \ / 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 }

如您所见，您得到了 302 重定向状态，但 redirect_count 为 0 。添加选项后，我得到：

{ url： http：\ / \ / 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 ：1，1，总时间：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编码请求参数，并按照重定向进行操作

$ str = urlencode（ userNamedenc = hGJfsdnk％601t& passwordenc = 675894242fa9c66939d9fcf4d5c39d1830f4ddb9& accessCode = -825374456）; curl_setopt_array（ $ curl，array（ CURLOPT_URL => www.mca.gov.in/mcafoportal/loginValidateUser.do，//<-删除的参数这里 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，//<--在此添加 CURLOPT_HTTPHEADER => ; array（ cache-control：no-cache ），））;

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": "http:\/\/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": "http:\/\/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": "http:\/\/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" ) , ) );
