Detailed description of obtaining email addresses based on PHPCURL

This article provides a detailed analysis of PHP's use of CURL to obtain the email address. if you need a friend, refer to CURL, which is essential for Home Travel. why is it so described? It is because of its ease of use that it can easily capture pages, simulate logon collection, and other functions.
Remember that the first time you contact CURL, you must capture the list of Mailbox users. At that time, in order to catch up with the progress, I did not study it carefully, but I found some information online to implement the function. Now we can sort out the original code and the function is still usable.
The code is as follows:
Error_reporting (0 );
Set_time_limit (0 );
Header ("Content-Type: text/html; charset = GB2312 ");

// Email user name and password
$ User = 'username ';
$ Pass = 'password ';

// Create a file to store cookie information
Define ("COOKIEJAR", tempnam (ini_get ("upload_tmp_dir"), "cookie "));

$ Url = 'http: // reg.163.com/logins.jsp? Type = 1 & url = http://entry.mail.163.com/coremail/fcg/ntesdoor2? Lightweight % 3D1% 26 verifycookie % 3D1% 26 language % 3D-1% 26 style % 3D-1 ';
$ Refer = 'http: // mail.163.com ';
$ Fields_post = array ('username' => $ user, 'password' => $ pass, 'verifycookie '=> 1, 'Style' =>-1, 'product' => 'mail163', 'seltype' =>-1, 'Secure '=> 'on ');
$ Fields_string = http_build_query ($ fields_post ,'&');
$ Headers_login = array ('User-agent' => 'mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv: 1.9) gecko/2008052906 Firefox/3.0 ', 'referer' => 'http: // www.163.com ');

// Log on
$ Ch = curl_init ($ url );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true );
Curl_setopt ($ ch, CURLOPT_HEADER, true );
Currochelle setopt ($ ch, CURLOPT_CONNECTTIMEOUT, 120 );
Curl_setopt ($ ch, CURLOPT_POST, true );
Curl_setopt ($ ch, CURLOPT_REFERER, $ refer );
Curl_setopt ($ ch, CURLOPT_COOKIESESSION, true );
Curl_setopt ($ ch, CURLOPT_COOKIEJAR, COOKIEJAR );
Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ headers_login );
Curl_setopt ($ ch, CURLOPT_POST, count ($ fields ));
Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ fields_string );
$ Result = curl_exec ($ ch );
Curl_close ($ ch );

// Jump
$ Url = 'http: // entry.mail.163.com/coremail/fcg/ntesdoor2? Lightweight = 1 & verifycookie = 1 & language =-1 & style =-1 & username = loki_wuxi ';
$ Headers = array ('User-agent' => 'mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv: 1.9) gecko/2008052906 Firefox/3.0 ');

$ Ch = curl_init ($ url );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true );
Curl_setopt ($ ch, CURLOPT_HEADER, true );
Currochelle setopt ($ ch, CURLOPT_CONNECTTIMEOUT, 120 );
Curl_setopt ($ ch, CURLOPT_POST, true );
Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ headers );
Curl_setopt ($ ch, CURLOPT_COOKIEFILE, COOKIEJAR );
Curl_setopt ($ ch, CURLOPT_COOKIEJAR, COOKIEJAR );
$ Result = curl_exec ($ ch );
Curl_close ($ ch );

// Obtain the sid
Preg_match ('/sid = [^ \ "]. */', $ result, $ location );
$ Sid = substr ($ location [0], 4,-1 );

// Address book
$ Url = 'http: // g4a30.mail.163.com/jy3/address/addrlist.jsp? Sid = '. $ sid.' & gid = all ';
$ Headers = array ('User-agent' => 'mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv: 1.9) gecko/2008052906 Firefox/3.0 ');

$ Ch = curl_init ($ url );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true );
Curl_setopt ($ ch, CURLOPT_HEADER, true );
Currochelle setopt ($ ch, CURLOPT_CONNECTTIMEOUT, 120 );
Curl_setopt ($ ch, CURLOPT_POST, true );
Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ headers );
Curl_setopt ($ ch, CURLOPT_COOKIEFILE, COOKIEJAR );
Curl_setopt ($ ch, CURLOPT_COOKIEJAR, COOKIEJAR );
$ Result = curl_exec ($ ch );
Curl_close ($ ch );
Unlink (COOKIEJAR );

// Start capturing content
Preg_match_all ('/] *> (.*?) <\/A> <\/td>] *> (.*?) <\/A> <\/td>/I ', $ result, $ infos, PREG_SET_ORDER );
// 1: Name 2: email
Print_r ($ infos );
?>

After you create a php file and copy the above code, the results will be immediate. remember to change your email account and password without the @ suffix. CURL's initial experience is not bad.
Later, I saw someone posting on CSDN asking me a question about how to obtain the express delivery query. he wanted to make some large express delivery company query services on a page, it is indeed a very good utility tool, but because the courier query has a verification code, it reminds me of the CURL tool. To help the Post Master implement the function, the idea is very simple. first use CURL to simulate the capture of the verification code, and then display it to the user submission page, at the same time, the COOKIE that saves the verification code and other user queries are submitted together to ensure COOKIE synchronization.

The source code is as follows:
-GetEms.html
The code is as follows:



EMS Express query


Fclose(fopen('cookie.txt ', 'w'); // The cookie.txt file is used to store the obtained cookie.
$ Cookiejar = realpath('cookie.txt ');
$ Fp = fopen ("example_homepage.txt", "w"); // The example_homepage.txt file is used to store the obtained page content.
$ Ch = curl_init ("http://www. EMS .com.cn/servlet/ImageCaptchaServlet ");
Curl_setopt ($ ch, CURLOPT_FILE, $ fp );
Curl_setopt ($ ch, CURLOPT_COOKIESESSION, 1 );
Curl_setopt ($ ch, CURLOPT_COOKIEJAR, $ cookiejar );
Curl_setopt ($ ch, CURLOPT_COOKIEFILE, $ cookiejar );
Curl_setopt ($ ch, CURLOPT_HEADER, 0 );
Curl_exec ($ ch );
Curl_close ($ ch );
Fclose ($ fp );

// Readfile ($ cookiejar); // view the obtained cookie
// Readfile ("example_homepage.jpg"); // view the obtained image
?>





-Getems. php
The code is as follows:
If ($ _ POST ){
// Cookie file using the previous verification code
$ Cookiejar = realpath('cookie.txt ');
// Get the variable name of myEmsbarCode and verification code
$ Ch = curl_init ("http://www. EMS .com.cn ");
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true );
Curl_setopt ($ ch, CURLOPT_HEADER, 0 );
Curl_setopt ($ ch, CURLOPT_COOKIEFILE, $ cookiejar );
Curl_setopt ($ ch, CURLOPT_COOKIEJAR, $ cookiejar );
$ Result = curl_exec ($ ch );
Curl_close ($ ch );
Preg_match ("/ /IsU ", $ result, $ myEmsbarCode );
Preg_match ("/<\/span>
$ Parm = array ($ codename [1] => $ _ POST ['code'],
MailNum => $ _ POST ['mailnum'],
MyEmsbarCode => $ myEmsbarCode [1],
ReqCode => 'browsebase'
);

$ Ch = curl_init ("http://www. EMS .com.cn/qcgzOutQueryAction.do ");
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 );
Curl_setopt ($ ch, CURLOPT_HEADER, 0 );
Curl_setopt ($ ch, CURLOPT_COOKIEFILE, $ cookiejar );
Curl_setopt ($ ch, CURLOPT_COOKIEJAR, $ cookiejar );
Curl_setopt ($ ch, CURLOPT_POST, 1 );
Curl_setopt ($ ch, CURLOPT_REFERER, "http://www. EMS .com.cn ");
Curl_setopt ($ ch, CURLOPT_POSTFIELDS, http_build_query ($ parm ));
$ _ Source = curl_exec ($ ch );
Curl_close ($ ch );

// Handle
Var_dump ($ _ source );
Exit;
}
?>

With this callback function, the response header information is automatically processed. The response header is the entire string. Set the return value to the string length.
Other CURL examples (from the network)
The code is as follows:
/*
* Determine whether a url is a valid link
*/
Function isRealUrl ($ url ){
$ Ch = curl_init ();
$ Options = array (
CURLOPT_URL => $ url,
CURLOPT_HEADER => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_NOBODY => true
);
Curl_setopt_array ($ ch, $ options );
Curl_exec ($ ch );
If (! Curl_errno ($ ch )){
Return 200 = curl_getinfo ($ ch, CURLINFO_HTTP_CODE )? True: false;
}
Curl_close ($ ch );
}

$ Url = 'http: // response ';
If (isRealUrl ($ url) {echo 'yes';} else {echo 'no ';}

/Asynchronous request example:

When you have mastered the php curl library, you can do a lot of things you want to do, I directly wrote a combat assistant, which is very easy to use. this code is not open-source. :) The principle is the same as that of open-source implementation.
