PHP simulated post Behavior Code summary (post is not absolutely safe) _php tips

Here are two ways to choose: First: Handwriting code. Second: Using HttpClient PHP class Library
The first method:

Copy Code code as follows:

? Php
$flag = 0;
The data to post
$ARGV = Array (
' var1 ' => ' abc ',
' Var2 ' => ' How are you? '
Construct the string to post
foreach ($argv as $key => $value) {
if ($flag!=0) {
$params. = "&";
$flag = 1;
}
$params. = $key. " ="; $params. = UrlEncode ($value);
$flag = 1;
}
$length = strlen ($params);
Create a socket connection
$fp = Fsockopen ("127.0.0.1", $errno, $errstr,) or exit ($ERRSTR.) ---> ". $errno);
To construct the header of a POST request
$header = "post/mobile/try.php http/1.1";
$header. = "host:127.0.0.1";
$header. = "referer:/mobile/sendpost.php";
$header. = "content-type:application/x-www-form-urlencoded";
$header. = "Content-length:" $length. "";
$header. = "Connection:close";
Add a Post string
$header. = $params. "";
Send the Post data
Fputs ($fp, $header);
$inheader = 1;
while (!feof ($fp)) {
$line = fgets ($fp, 1024); Removing the header of the request package shows only the return data of the page
if ($inheader && ($line = = "N" | | $line = = "")) {
$inheader = 0;
}
if ($inheader = = 0) {
Echo $line;
}
}
Fclose ($FP);
?>

The second approach is to: Use the HttpClient class

Copy Code code as follows:

$pageContents = Httpclient::quickpost (' Http://example.com/someForm ', Array (
' Name ' => ' Some name ',
' Email ' => ' email@example.com '
));

Use the HttpClient class library, you can go to the official download the latest class library, the official address is: http://scripts.incutio.com/httpclient/index.php
Add a few other uses of PHP httpclient
static method to get a Web page:

Copy Code code as follows:

$pageContents = Httpclient::quickget (' http://bankcha.com ')

Get method gets

Copy Code code as follows:

$client = new HttpClient (' bankcha.com ');
if (! $client->get ('/')) {
Die (' An error occurred: '. $client->geterror ());
}
$pageContents = $client->getcontent ();
Get method with Debug gets
PHP code
$client = new HttpClient (' bankcha.com ');
$client->setdebug (TRUE);
if (! $client->get ('/')) {
Die (' An error occurred: '. $client->geterror ());
}
$pageContents = $client->getcontent ();
Get method with automatic steering
PHP code
$client = new HttpClient (' www.bankcha.com ');
$client->setdebug (TRUE);
if (! $client->get ('/')) {
Die (' An error occurred: '. $client->geterror ());
}
$pageContents = $client->getcontent ();
Check if the page exists
PHP code
$client = new HttpClient (' bankcha.com ');
$client->setdebug (TRUE);
if (! $client->get ('/thispagedoesnotexist ')) {
Die (' An error occurred: '. $client->geterror ());
}
if ($client->getstatus () = = ' 404 ') {
Echo ' Page does not exist! ';
}
$pageContents = $client->getcontent ();
Fake client
PHP code
$client = new HttpClient (' bankcha.com ');
$client->setdebug (TRUE);
$client->setuseragent (' mozilla/5.0 (Windows; U Windows NT 5.1; En-us; rv:1.3a) gecko/20021207 ');
if (! $client->get ('/')) {
Die (' An error occurred: '. $client->geterror ());
}
$pageContents = $client->getcontent ();
Logon authentication and request a Web page
PHP code
$client = new HttpClient (' bankcha.com ');
$client->post ('/login.php ', Array (
' username ' => ' Simon ',
' Password ' => ' ducks '
));
if (! $client->get ('/private.php ')) {
Die (' An error occurred: '. $client->geterror ());
}
$pageContents = $client->getcontent ();
HTTP Authorization
PHP code
$client = new HttpClient (' bankcha.com ');
$client->setauthorization (' Username ', ' Password ');
if (! $client->get ('/')) {
Die (' An error occurred: '. $client->geterror ());
}
$pageContents = $client->getcontent ();
Output header information
PHP code
$client = new HttpClient (' bankcha.com ');
if (! $client->get ('/')) {
Die (' An error occurred: '. $client->geterror ());
}
Print_r ($client->getheaders ());
Sets the maximum number of redirects in a domain
PHP code
$client = new HttpClient (' www.bankcha.com ');
$client->setdebug (TRUE);
$client->setmaxredirects (3);
$client->get ('/');

PHP Fsockopen forged Post and Get methods
Fsockopen forged Post and get methods well, if you're looking for a PHP code that forges the post and getting methods, this is good.

Copy Code code as follows:

<?php
Fsocket Analog Post Submission
$purl = "Http://localhost/netphp/test2.php?uu=rrrrrrrrrrrr";
Print_r (Parse_url ($url));
Sock_post ($purl, "uu=55555555555555555");
Fsocket Simulate Get commit
function Sock_get ($url, $query)
{
$info = Parse_url ($url);
$fp = Fsockopen ($info ["host"], $errno, $ERRSTR, 3);
$head = "Get". $info [' Path ']. $info ["Query"]. Http/1.0rn ";
$head. = "Host:". $info [' Host ']. " RN ";
$head. = "RN";
$write = fputs ($fp, $head);
while (!feof ($FP))
{
$line = Fread ($fp, 4096);
Echo $line;
}
}
Sock_post ($purl, "uu=rrrrrrrrrrrrrrrr");
function Sock_post ($url, $query)
{
$info = Parse_url ($url);
$fp = Fsockopen ($info ["host"], $errno, $ERRSTR, 3);
$head = "POST". $info [' Path ']. $info ["Query"]. Http/1.0rn ";
$head. = "Host:". $info [' Host ']. " RN ";
$head. = "referer:http://". $info [' Host ']. $info [' Path ']. " RN ";
$head. = "CONTENT-TYPE:APPLICATION/X-WWW-FORM-URLENCODEDRN";
$head. = "Content-length:". strlen (Trim ($query)). RN ";
$head. = "RN";
$head. = Trim ($query);
$write = fputs ($fp, $head);
while (!feof ($FP))
{
$line = Fread ($fp, 4096);
Echo $line;
}
}
?>
