Detailed explanation of using Php's CURL POST to submit form login examples_PHP tutorial

I have talked a lot about the php curl function to implement post submission data. Now I will introduce to you one way to submit xml and one way to submit form data.

Example 1

CURL uses POST to submit XML data

The code is as follows

Copy code

代码如下

复制代码

$url = "http://www.bKjia.c0m";    $ch = curl_init(); $header[] = "Content-type: text/xml";//定义content-type为xml curl_setopt($ch, CURLOPT_URL, $url); //定义表单提交地址 curl_setopt($ch, CURLOPT_POST, 1);   //定义提交类型 1：POST ；0：GET curl_setopt($ch, CURLOPT_HEADER, 1); //定义是否显示状态头 1：显示 ； 0：不显示 curl_setopt($ch, CURLOPT_HTTPHEADER, $header);//定义请求类型 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);//定义是否直接输出返回流 curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //定义提交的数据，这里是XML文件  curl_close($ch);//关闭

$url = "http://www.bKjia.c0m";

$ch = curl_init();

$header[] = "Content-type: text/xml";//Define content-type as xml curl_setopt($ch, CURLOPT_URL, $url); //Define form submission address curl_setopt($ch, CURLOPT_POST, 1); //Define submission type 1: POST; 0: GET

curl_setopt($ch, CURLOPT_HEADER, 1); //Define whether to display the status header 1: display; 0: not display

curl_setopt($ch, CURLOPT_HTTPHEADER, $header);//Define request type
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0); //Define whether to directly output the return stream

curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //Define the submitted data, here is the XML file

代码如下

复制代码

set_time_limit(0); @date_default_timezone_set('Asia/Shanghai'); function curlrequest($url,$postfield,$proxy=""){ $proxy=trim($proxy); $user_agent ="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)"; $ch = curl_init(); // 初始化CURL句柄 if(!empty($proxy)){ curl_setopt ($ch, CURLOPT_PROXY, $proxy);//设置代理服务器 } curl_setopt($ch, CURLOPT_URL, $url); //设置请求的URL //curl_setopt($ch, CURLOPT_FAILONERROR, 1); // 启用时显示HTTP状态码，默认行为是忽略编号小于等于400的HTTP信息 //curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);//启用时会将服务器服务器返回的“Location:”放在header中递归的返回给服务器 curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);// 设为TRUE把curl_exec()结果转化为字串，而不是直接输出 curl_setopt($ch, CURLOPT_POST, 1);//启用POST提交 curl_setopt($ch, CURLOPT_POSTFIELDS, $postfield); //设置POST提交的字符串 //curl_setopt($ch, CURLOPT_PORT, 80); //设置端口 curl_setopt($ch, CURLOPT_TIMEOUT, 25); // 超时时间 curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);//HTTP请求User-Agent:头 //curl_setopt($ch,CURLOPT_HEADER,1);//设为TRUE在输出中包含头信息 //$fp = fopen("example_homepage.txt", "w");//输出文件 //curl_setopt($ch, CURLOPT_FILE, $fp);//设置输出文件的位置，值是一个资源类型，默认为STDOUT (浏览器)。 curl_setopt($ch,CURLOPT_HTTPHEADER,array( 'Accept-Language: zh-cn', 'Connection: Keep-Alive', 'Cache-Control: no-cache' ));//设置HTTP头信息 $document = curl_exec($ch); //执行预定义的CURL $info=curl_getinfo($ch); //得到返回信息的特性 //print_r($info); if($info[http_code]=="405"){ echo "bad proxy {$proxy}n"; //代理出错 exit; } //curl_close($ch); return $document; } //请求URL $url="http://example.cn/getInfo.php"; //POST提交数据，可用HTTPWATCH查看 $postfield="userName=test&year=2008&passWord=123456&Submit=%CC%E1%BD%BB"; //代理服务器 $proxy = ''; //请求 $str=curlrequest($url,$postfield,$proxy); //输出结果 echo $str;

curl_close($ch);//Close<🎜>

Example 3, a simple login example using curl post

Simulate post login submission form problem

SOOPY class:
I wrote a program before to simulate a post to push some resources
At first, like everyone else, the first thing that came to mind was to use PHP’s own library CURL to simulate various Baidu and Google
I want to be lazy and see if there is a simpler class to implement it?
I discovered him anyway, he is a snoopy type. (Chinese name Shi Lu)

The code is as follows

Copy code

代码如下

复制代码

//首先要引用这个类 include("/data/tools/pooy/Snoopy/Snoopy.class.php"); $snoopy = new Snoopy; //$Parameters这个是要提交的数组 $Parameters["username"] = "user"; $Parameters["pass"] = "pass"; $file = "/test/test.jpg"; $serviceUrl = "http://www.你的地址/fileProcess.php"; $postfiles["image"] = $file; //$filename上传文件相对路径 例如"upload/taoav.jpg";image/jpg $snoopy->_submit_type = "multipart/form-data"; //设定submit类型 $snoopy->submit($serviceUrl,$Parameters,$postfiles);

//First reference this class include("/data/tools/pooy/Snoopy/Snoopy.class.php"); $snoopy = new Snoopy; //$Parameters is the array to be submitted $Parameters["username"] = "user"; $Parameters["pass"] = "pass"; $file = "/test/test.jpg"; $serviceUrl = "http://www.your address/fileProcess.php"; $postfiles["image"] = $file; //$filename relative path to upload file For example "upload/taoav.jpg";image/jpg $snoopy->_submit_type = "multipart/form-data"; //Set the submit type $snoopy->submit($serviceUrl,$Parameters,$postfiles);

//$postforms, $postfiles are values ​​of the 2 types, where $postfiles is an array of uploaded files

The above example implements a POST form submission case. Due to the complex requirements, the function of snoopy could not meet my needs, so I started again
Go attack CURL.
CURL extension library:
This library is a relatively mature extension library with very powerful functions. Powerful enough to simulate any action of the browser.
The requirements are like this:
Log in to a website backend for the first time
Second interface page, and then start pushing a large amount of resources
(The specific logic here is abbreviated)
For the convenience of operation, I encapsulated several functions I need to simulate into a class. The short code is as follows:

The above is a perfect solution to this problem using CURL, which can effectively solve the cookie storage problem.

The code is as follows

Copy code

/* ​​Simulation resource push class 2012-09-14 by POOY */ class TuisongPost{ //Use structure login authentication Function TuisongPost(){ //Storage COOKIE file global $cookie_jar;                 $this->cookie_jar = tempnam('./tmp','cookie');              $url = "http://www.your address";                 $post_data = array( "username" => "admin","password" => "admin" );              $ch = curl_init(); ​​​​​ curl_setopt($ch, CURLOPT_URL, $url); ​​​​​ curl_setopt($ch, CURLOPT_POST, 1); ​​​​​ curl_setopt($ch, CURLOPT_HEADER, 1); ​​​​​ curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);             curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);               curl_setopt($ch, CURLOPT_COOKIEJAR, $this->cookie_jar); //Save cookie information               $output1 = curl_exec($ch);              curl_close($ch); //echo $this->cookie_jar."n"; }   /*Get group ID*/  Function getGid($groupname,$channel,$lanmu){ $url = "http://XXXX.com/creategroup"; //Format the data to be pushed               $data = $this->getGidArr($groupname,$channel,$lanmu);              $ch = curl_init();               $Ref_url = "http://www.your address"; ​​​​​ curl_setopt($ch, CURLOPT_URL, $url);             curl_setopt($ch, CURLOPT_REFERER, $Ref_url);              curl_setopt($ch, CURLOPT_POST, 1); //Submit data in post mode                curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //Return data instead of outputting it directly                curl_setopt($ch, CURLOPT_HEADER, 0); // Set whether to display header information. 0 means not to display, 1 means to display.
