Problems with PHP Impersonation login

Problems with PHP Impersonation login
On the Internet to read a series of articles to simulate Renren login, exactly now need to use, but appeared "the URL has moved here" is what reason AH. Thank you, the code is as follows:

PHP Code

  $login _url = ' http://passport.renren.com/PLogin.do ';    $post _fields[' email '] = ' xxx@gmail.com ';    $post _fields[' password '] = ' xxx ';    $post _fields[' origurl '] = ' http://www.renren.com/indexcon ';    $post _fields[' domain '] = ' renren.com ';    The cookie file is stored under the Temp folder in the root directory of the Web site $cookie _file = Tempnam ('./temp ', ' Cookie ');    $ch = Curl_init ($login _url); curl_setopt ($ch, Curlopt_useragent, ' mozilla/5.0 (Windows; U Windows NT 5.1; ZH-CN;    rv:1.9.1.5) gecko/20091102 firefox/3.5.5 ');    curl_setopt ($ch, Curlopt_header, 0);    curl_setopt ($ch, Curlopt_returntransfer, 1);    curl_setopt ($ch, Curlopt_maxredirs, 1);    curl_setopt ($ch, curlopt_followlocation, 1);    curl_setopt ($ch, Curlopt_autoreferer, 1);    curl_setopt ($ch, Curlopt_post, 1);    curl_setopt ($ch, Curlopt_postfields, $post _fields);    curl_setopt ($ch, Curlopt_cookiejar, $cookie _file);    Curl_exec ($ch);    Curl_close ($ch);    Bring a cookie file, visit Renren homepage $send _url= ' http://home.renren.com/Home.do ';    $ch = Curl_init ($send _url); Curl_Setopt ($ch, Curlopt_header, 0);    curl_setopt ($ch, Curlopt_returntransfer, 1);    curl_setopt ($ch, Curlopt_cookiefile, $cookie _file);    $contents = curl_exec ($ch);    Curl_close ($ch);    Clean cookie file unlink ($cookie _file); Output Renren Home page content Print_r ($contents);

------Solution--------------------
The following content is posted.

This two-day simulation browser submits the login form, after submission is complete, the URL has movedhere.

Each time you need to click Connect to open the Login home page. That's not what I want.

Read again the description, see parameter-L

As follows:-l/--location follow location:hints (H)
--location-trusted follow Location:and send auth to other hosts (H)

A little impulsive, feeling this is the key to the problem:

Curl--output "./rr.html"--dump-header "d_cookie01"--cookie-jar "c_cookie01"--create-dirs--location--data "email= test&password=test&autologin=ture&origurl=&domain=renren.com&formname=&method=& isplogin=true&submit= Login "Http://www.renren.com/PLogin.do

Wowowo Login after the homepage download down!!



Take a closer look at the D_COOKIE01 (containing content from C_COOKIE01, but the more concise--cookie-jar produced) there is such a

location:http://www.renren.com/callback.do?t=9d5201d04d44156fb070037e9493f5fd3&origurl=http%3a%2f% 2fwww.renren.com%2fhome.do&neednotify=false

The original after each submission of login form also need to jump, and-L is to follow the jump link.



We can also do it in two steps:

1. Submit the form first to save the returned cookie
Curl--output "./rr.html"--dump-header "d_cookie01"--data "email=test&password=test&autologin=ture& origurl=& domain=renren.com&formname=&method=&isplogin=true& submit= Login "http://www.renren.com /plogin.do
2. Locate the location in the D_COOKIE01 and submit the cookie and location together
Curl--output "./rr.html"--dump-header "d_cookie01"--location http://www.renren.com/callback.do?t= 9d5201d04d44156fb070037e9493f5fd3&origurl=http%3a%2f%2fwww.renren.com%2fhome.do&neednotify=false

OK, you get the home page after you sign in.
