Curl is a must-have killer for home travel. It's because he's easy to use. It can achieve a series of functions such as page capture simulation login collection.
Remember the first time you touch curl is to achieve the completion from the mailbox user list crawl. At that time in order to catch up without careful study just online to find some information to achieve the function. Now the original code to tidy up the function can still be used
Copy CodeThe code is as follows:
error_reporting (0);
Set_time_limit (0);
Header ("content-type:text/html; charset=gb2312 ");
Mailbox User name Password
$user = ' username ';
$pass = ' password ';
Create a file to hold cookie information

Create a php file copy the above code saved immediately after the effect, remember to change the mailbox account and password, the account does not need the @ suffix. Curl first experience, how, not bad.
Later on in the CSDN and see others posted asked a query to get express queries, he wants to put some big Express Company query business to do in a page, is indeed a very good practical gadgets, but because the express query has a verification code, not from the I think of Curl sharp weapon. Later to help the main implementation of the function, the idea is simple, first use curl simulation to crawl the verification code, and then display to the user submission page, while saving the verification code of the cookie and other user queries together to ensure that the cookie synchronization.
The source code is as follows:
-getems.html
Copy CodeThe code is as follows:
<title>EMS Express Query</title>
Fclose (fopen (' Cookie.txt ', ' W ')); File cookie.txt for storing the cookie obtained
$cookiejar = Realpath (' cookie.txt ');
$fp = fopen ("Example_homepage.txt", "w"); File example_homepage.txt for storing the content of the page obtained
$ch = Curl_init ("Http://www.ems.com.cn/servlet/ImageCaptchaServlet");
curl_setopt ($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 cookie that was taken
ReadFile ("example_homepage.jpg"); To view the pictures taken
?>

Copy CodeThe code is as follows:

$cookiejar = Realpath (' cookie.txt ');
Get the Myemsbarcode number and Authenticode variable names

When you mastered the PHP Curl library You can do a lot of things you want to do, hehe, not long ago to play the X world of happy, fighting is really cumbersome, I directly wrote a combat assistant very useful, this code is not open Source:) Master principle as open source implementation.
