PHP's curl implements Get,post and cookies (example) _php tutorial

Similar to dreamhost such as host service providers, is to display the use of fopen. Use of PHP's curl can be implemented to support FTP, FTPS, HTTP htpps SCP SFTP TFTP, TELNET DICT file and LDAP. Curl supports SSL certificates, HTTP POST, http PUT, FTP uploads, Kerberos, HTT-based uploads, proxies, cookies, user + password proofs, File transfer recovery, HTTP proxy channels are most commonly used, HTTP-based Get and Post methods.
Code implementation:
1. Get implementation of HTTP
Copy CodeThe code is as follows:
$ch = Curl_init ("Http://www.domain.com/api/index.php?test=1");
curl_setopt ($ch, Curlopt_returntransfer, true); Get Data back
curl_setopt ($ch, Curlopt_binarytransfer, true); Gets the data back when Curlopt_returntransfer is enabled
echo $output = curl_exec ($ch);

/* Write file */
$fh = fopen ("out.html", ' W ');
Fwrite ($FH, $output);
Fclose ($FH);

2, the HTTP POST implementation
Copy CodeThe code is as follows:
$url = ' http://www.domain.com/api/';
$fields = Array (
' lname ' = ' justcoding ',
' fname ' = ' phplover ',
' Title ' = ' MyApi ',
' Age ' = ' 27 ',
' Email ' = ' 1353777303@gmail.com ',
' Phone ' = ' 1353777303 '
);
$post _data = Implode (' & ', $fields);

Note:The parameters of the post request are to be connected as a string by a Get method:
such as:$params = ' userid= '. $this->user_id. ' &auth= '. $this->auth. ' &sig= '. $this->sig

There are cross-platform requests, curl_setopt ($ch, curlopt_followlocation, 1); Use Auto jump (very important)

Open connection
$ch = Curl_init ();
Set the URL, number of post VARs, post data
curl_setopt ($ch, Curlopt_url, $url);
curl_setopt ($ch, Curlopt_post,count ($fields)); When enabled, a regular post request is sent with the type: application/x-www-form-urlencoded, just as the form was submitted.
curl_setopt ($ch, Curlopt_postfields, $fields); The "POST" operation in HTTP. If you want to transfer a file, you need a filename at the start of the @

Ob_start ();
Curl_exec ($ch);
$result = Ob_get_contents ();
Ob_end_clean ();

echo $result;

Close connection
Curl_close ($ch);

Copy CodeThe code is as follows:

if ($_get[' test ')
{
Print_r ($_get);
}

if ($_post)
{
Print_r ($_post);
}

PHP's Curl transfer cookie

two different ways:
One is automatic:
Copy CodeThe code is as follows:
curl_setopt ($curlHandle, Curlopt_cookiejar, ' cookie.txt '); Save
curl_setopt ($curlHandle, Curlopt_cookiefile, ' cookie.txt '); Read

This will automatically keep the cookie up.
But two times, one is to first access the cookie, then the link to use the cookie
Example:
Copy CodeThe code is as follows:

function Get_curlcuconent2 ($filename, $referer)
{
$cookie _jar = Tempnam ('./tmp ', ' Jsessionid ');

$ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, $filename);
curl_setopt ($ch, Curlopt_header, false);
curl_setopt ($ch, Curlopt_returntransfer, 1);

Set cookie path for file read and submit
curl_setopt ($ch, Curlopt_cookiejar, $cookie _jar);
$filecontent =curl_exec ($ch);
Curl_close ($ch);

$ch = Curl_init ();
$hostname = "www.domain.com";
$referer = "http://www.domain.com/";
curl_setopt ($ch, Curlopt_url, $filename);
curl_setopt ($ch, Curlopt_referer, $referer); Look here, you can also say you come from Google
curl_setopt ($ch, Curlopt_useragent, "www.domain.com");

$request = "jsessionid=abc6szw15ozvz_pu9b-8r"; Set Post Parameters
curl_setopt ($ch, Curlopt_postfields, $request);
Above this sentence, of course you can say you are Baidu, get rid of the value here OK, can realize the function of Thief, $_server[' http_user_agent ']
You can make yourself a spider, so pretend to be the curlopt_useragent.
If you want to put this program on Linux with Php-q execution that also write specific $_server[' http_user_agent ', forged can also
curl_setopt ($ch, Curlopt_returntransfer, 1);
curl_setopt ($ch, Curlopt_cookiefile, $cookie _jar);
curl_setopt ($ch, Curlopt_header, false);//Set whether to output page content
curl_setopt ($ch, Curlopt_get, 1); Post,get Past

$filecontent = curl_exec ($ch);
Preg_match_all ("/charset= (. +?) [null\ "\ ']/is", $filecontent, $charsetarray);
if (Strtolower ($charsetarray [1][0]) = = "Utf-8")
$filecontent =iconv (' utf-8 ', ' Gb18030//ignore ', $filecontent);
Curl_close ($ch);
return $filecontent;
}

?>

A custom:
Copy CodeThe code is as follows:
$header []= ' Accept:image/gif, Image/x-xbitmap, Image/jpeg, Image/pjpeg, Application/x-shockwave-flash, text/html, * '. '/* ';
$header []= ' ACCEPT-LANGUAGE:ZH-CN ';
$header []= ' user-agent:mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1;. NET CLR 2.0.50727) ';
$header []= ' Host: '. $ your target host;
$header []= ' connection:keep-alive ';
$header []= ' Cookie: '. $ your cookie string;

curl_setopt ($curlHandel, Curlopt_httpheader, $header);
