#?或者?↓↓

$?curl?http://www.linuxidc.com?>?page.html

To capture a specific file, use -O (capital), and the following URL must be specific to a certain file, otherwise it will not be captured. We can also use regular expressions to capture things, but the file name still has to be specific

Transfer data, it is best to use the login page to test, because after you pass the value, curl will capture the data, and you can see that you passed Is it successful?

curl?-d?log=aaaa??http://www.codesky.net/wp-login.php

Forge the source address. Some websites will judge and request the source address

curl?-e?http://localhost?http://www.codesky.net/wp-login.php

When we often use curl to get other people’s things, they will block your IP. At this time, we You can use a proxy

Use of curl under PHP scripts

Install cURL Library

WAMP environment
Open the following 2 files respectively:
wampbinphp(your php version)php.ini
wampbinApache(your apache version)binphp.ini
Search for extension=php_curl.dll, and then delete the previous symbols;
Restart WAMP That’s it.
//↑↑Follow the above operations first, if not, then refer to the following two;
Note: If it is a 64-bit system, you also need to visit http://www.anindya.com/ to download the corresponding version of 64-bit php Compressed package, after decompression, overwrite the php_curl.dll file in the ext directory with the php_curl.dll file in the ext directory of wamp php corresponding version wampbinphpphp5.4.12, and then restart WAMP
Reference website: http://blog.csdn.net/ewili/ article/details/9008493

window
1.php.ini remove the semicolon in front of extension=php_curl.dll;
2.php_curl.dll,libeay32.dll,ssleay32.dll and copy them to %windir%/system32

linux
If php has been compiled in the system, new extensions need to be added later. One way is to completely recompile PHP, and the other way is to compile the extension library separately and extend it in the form of extension. The following is an example of installing the curl extension:
./configure
make
php requires that the curl directory must have include and lib directories, and there must be two files easy.h and curl.h under include, and libcurl.a must be under lib. . After compilation, the files in include exist, but not in the lib directory. It was originally generated in the lib/.libs directory, so you need to copy it to the lib directory

2. Enter the source code directory where the original php was installed,
cd ext
cd curl
phpize
./configure --with-curl=DIR
make
The curl.so file will be generated under PHPDIR/ext/curl/moudles/. U Curl function library
