Using Php CURLPOST to submit a form to log on to an instance _ PHP Tutorial

Use Php CURLPOST to submit a form to log on to the instance. I have mentioned a lot about the phpcurl function to implement post data submission. next I will introduce you to submit xml and form data. For example, 1CURL uses POST to submit XML data code. I have mentioned a lot about the php curl function to implement post to submit data. next I will introduce you to submit xml and form data.

Example 1

CURL uses POST to submit XML data

The code is as follows:

$ Url = "http://www.bKjia. c0m "; $ Ch = curl_init (); $ Header [] = "Content-type: text/xml"; // Define content-type as xml Curl_setopt ($ ch, CURLOPT_URL, $ url); // defines the form submission address Curl_setopt ($ ch, CURLOPT_POST, 1); // defines the submission Type 1: POST; 0: GET Curl_setopt ($ ch, CURLOPT_HEADER, 1); // defines whether to display Status Header 1: Display; 0: not Display Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ header); // define the request type Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 0); // you can specify whether to directly output the returned stream. Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data); // defines the submitted data, which is an XML file. Curl_close ($ ch); // Close

When using POST to submit XML data in PHP, you must define content-type as xml. Otherwise, the default value is text/html!

Example 2: post form data

Curl is a file transfer tool that uses the URL syntax to work in the command line mode.
Php Tutorial example:

The code is as follows:

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 (); // initialize the CURL handle If (! Empty ($ proxy )){ Curl_setopt ($ ch, CURLOPT_PROXY, $ proxy); // sets the proxy server } Curl_setopt ($ ch, CURLOPT_URL, $ url); // you can specify the request URL. // Curl_setopt ($ ch, CURLOPT_FAILONERROR, 1); // The HTTP status code is displayed when it is enabled. the default behavior is to ignore the HTTP information whose number is less than or equal to 400. // Curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, 1); // When enabled, the "Location:" returned by the server is put in the header and recursively returned to the server. Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); // set to TRUE to convert the curl_exec () result into a string instead of directly outputting Curl_setopt ($ ch, CURLOPT_POST, 1); // enable POST submission Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ postfield); // you can specify a string for POST submission. // Curl_setopt ($ ch, CURLOPT_PORT, 80); // Set the port Curl_setopt ($ ch, CURLOPT_TIMEOUT, 25); // timeout Curl_setopt ($ ch, CURLOPT_USERAGENT, $ user_agent); // HTTP request User-Agent: Header // Curl_setopt ($ ch, CURLOPT_HEADER, 1); // Set TRUE to include header information in the output // $ Fp = fopen ("example_homepage.txt", "w"); // output file // Curl_setopt ($ ch, CURLOPT_FILE, $ fp); // set the location of the output file. The value is a resource type. the default value is STDOUT (browser ). Curl_setopt ($ ch, CURLOPT_HTTPHEADER, array ( 'Accept-Language: zh-cn ', 'Connection: Keep-alive ', 'Cache-Control: no-cache' ); // Set HTTP header information $ Document = curl_exec ($ ch); // execute the predefined CURL $ Info = curl_getinfo ($ ch); // Obtain the returned information. // Print_r ($ info ); If ($ info [http_code] = "405 "){ Echo "bad proxy {$ proxy} n"; // proxy error Exit; } // Curl_close ($ ch ); Return $ document; } // Request URL $ Url = "http://example.cn/getInfo.php "; // Submit data in POST mode and can be viewed by HTTPWATCH. $ Postfield = "userName = test & year = 2008 & passWord = 123456 & Submit = % CC % E1 % BD % BB "; // Proxy server $ Proxy = ''; // Request $ Str = curlrequest ($ url, $ postfield, $ proxy ); // Output result Echo $ str;

Example 3: a simple curl post login instance

Simulate post login and submit a form

SOOPY class:
I wrote a program to simulate post to push some resources.
At first, like everyone else, Baidu Google first came up with the library CURL that comes with PHP to simulate
I want to secretly and lazy to see if there are simpler classes for implementation?
I found out that it is the snoopy class. (Chinese name: RS)

The code is as follows:

// Reference this class first Include ("/data/tools/pooy/Snoopy. class. php "); $ Snoopy = new Snoopy; // $ Parameters: 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: the relative path of the uploaded file, for example, "upload/taoav.jpg"; image/jpg $ Snoopy-> _ submit_type = "multipart/form-data"; // you can specify the submit type. $ Snoopy-> submit ($ serviceUrl, $ Parameters, $ postfiles );

// $ Postforms, $ postfiles is a value of type 2, where $ postfiles is an array of uploaded files

The above example shows a case of POST form submission. Due to the complex requirements, this snoopy function cannot meet my needs, so I started
Attack CURL.
CURL Extension Library:
This library is a mature extension library with powerful functions. Powerful enough to simulate any action of the browser.
The requirement is as follows:
First, log on to the background of a website.
Second interface page, and then start to push a large number of resources
(The specific logic here is reduced)
For ease of operation, I encapsulate several functions that I need to simulate into a class. The short code is as follows:

The code is as follows:

/* Simulate resource push class 2012-09-14 by POOY */ Class TuisongPost { // Construct login authentication Function TuisongPost (){ // The file that stores the COOKIE Global $ cookie_jar; $ This-> cookie_jar = tempnam ('./tmp', 'cooker '); $ 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 the 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); // disguise REFERER Curl_setopt ($ ch, CURLOPT_POST, 1); // submit data in post mode Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); // return data instead of directly outputting Curl_setopt ($ ch, CURLOPT_HEADER, 0); // you can specify whether to display the header information. 0 indicates that the header information is not displayed. 1 indicates that the default value is 0. Curl_setopt ($ ch, CURLOPT_COOKIEFILE, $ this-> cookie_jar); // send the cookie file Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data); // send POST data $ Output2 = curl_exec ($ ch); // send an HTTP request // The returned value is used as the basis for judgment. Return $ output2; Curl_close ($ ch ); // $ This-> unlink ($ this-> cookie_jar ); } // Push data Function sendPic ($ note, $ groupid, $ groupindex, $ img ){ $ Url = "http: // XXXX/addimage "; $ Groupid = intval ($ groupid ); $ Data = $ this-> sendPicArr ($ note, $ groupid, $ groupindex, $ img ); $ Ch = curl_init (); $ Ref_url = "http: // www. your address "; Curl_setopt ($ ch, CURLOPT_URL, $ url ); Curl_setopt ($ ch, CURLOPT_REFERER, $ Ref_url); // disguise REFERER Curl_setopt ($ ch, CURLOPT_POST, 1); // submit data in post mode Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); // return data instead of directly outputting Curl_setopt ($ ch, CURLOPT_HEADER, 0); // you can specify whether to display the header information. 0 indicates that the header information is not displayed. 1 indicates that the default value is 0. Curl_setopt ($ ch, CURLOPT_COOKIEFILE, $ this-> cookie_jar); // send the cookie file Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data); // send POST data $ Output2 = curl_exec ($ ch); // send an HTTP request Return $ output2; Curl_close ($ ch ); // $ This-> unlink ($ this-> cookie_jar ); } /* Push data operation */ Function sendMes ($ url, $ img, $ imgdesc, $ groupid, $ groupname, $ channel, $ lanmu) { // Var_dump ($ this-> cookie_jar ); // Exit (); $ Url = "http: // XXXX/add "; $ Data = $ this-> getArr ($ img, $ imgdesc, $ groupid, $ 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); // disguise REFERER Curl_setopt ($ ch, CURLOPT_POST, 1); // submit data in post mode Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); // return data instead of directly outputting Curl_setopt ($ ch, CURLOPT_HEADER, 0); // you can specify whether to display the header information. 0 indicates that the header information is not displayed. 1 indicates that the default value is 0. Curl_setopt ($ ch, CURLOPT_COOKIEFILE, $ this-> cookie_jar); // send the cookie file Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data); // send POST data $ Output2 = curl_exec ($ ch); // send an HTTP request Curl_close ($ ch ); // $ This-> unlink ($ this-> cookie_jar ); } Function getArr ($ img, $ imgdesc, $ groupid, $ groupname, $ channel, $ lanmu) { $ Post_data = array ( // Use the following statement in windows. linux is not applicable. // "Img" => "@". $ img. "; type = image/jpeg ", "Img" => "@". $ img, "Imgdesc" => $ imgdesc, "Groupid" => $ groupid, "Groupname" => $ groupname, "Channel" => $ channel, "Lanmu" => $ lanmu, "Cdate" => date ('Y-m-D ') ); Return $ post_data; } // Format getGidArr Function getGidArr ($ groupname, $ channel, $ lanmu) { $ Post_data = array ( "Groupname" => $ groupname, "Channel" => $ channel, "Lanmu" => $ lanmu, "Cdate" => date ('Y-m-D ') ); Return $ post_data; } // Format sendPicArr Function sendPicArr ($ note, $ groupid, $ groupindex, $ img) { $ Post_data = array ( "Notes" => $ note, "Id" => $ groupid, "Index" => $ groupindex, "Cdate" => date ('Y-m-D '), // Use the following statement in windows. linux is not applicable. // "Img" => "@". $ img. "; type = image/jpeg ", "Img" => "@". $ img ); Return $ post_data; } // Clear cookie files Function unlink ($ cookie_jar ){ Unlink ($ cookie_jar ); } }

The above uses CURL to solve this problem perfectly. it can effectively solve the cookie storage problem.

The curl function implements post data submission. next I will introduce a type of xml submission and a form of data submission. Example 1 CURL uses POST to submit XML data code...
