Summary of the example of submitting data using php curl to simulate post requests

In php, we will use the curl function to simulate post request data submission. Below I will give you a few examples of curl simulating post request data submission. For more information, see.

Note: The curl function is not supported by default in php. If you need to use the curl function, you need to modify your php. set the INI file and find php_curl.dll to remove the previous ";".

Example 1

The Code is as follows:

Copy code

<? Php $ Uri = "http://tanteng.duapp.com/test.php "; // Parameter Array $ Data = array ( 'Name' => 'tanteng' // 'Password' => 'Password' );   $ Ch = curl_init (); // Print_r ($ ch ); Curl_setopt ($ ch, CURLOPT_URL, $ uri ); Curl_setopt ($ ch, CURLOPT_POST, 1 ); Curl_setopt ($ ch, CURLOPT_HEADER, 0 ); Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1 ); Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data ); $ Return = curl_exec ($ ch ); Curl_close ($ ch );   Print_r ($ return ); Accept php page Remote Server: <? Php If (isset ($ _ POST ['name']) { If (! Empty ($ _ POST ['name']) { Echo 'hello, ', $ _ POST ['name'].'! '; } } ?>

Example 2

Use CURL to simulate POST request grabbing zip code and address

Complete code:

The Code is as follows:

Copy code

#! /Usr/local/php/bin/php <? Php $ Runtime = new runtime (); $ Runtime-> start (); $ Cookie_jar = tempnam ('/tmp', 'cooke ');   $ Filename = $ argv [1]; $ Start_num = $ argv [2]; $ End_num = $ argv [3];   For ($ I = $ start_num; $ I <$ end_num; $ I ++ ){ $ Zip = sprintf ('6s ', $ I ); $ Fields_post = array ( 'Postcode' => $ zip, 'Querykind' => 2, 'Reqcode' => 'goopsearch ', 'Search _ button. x' => 37, 'Search _ button. y' => 12 ); $ Fields_string = http_build_query ($ fields_post ,'&'); $ Ch = curl_init (); Curl_setopt ($ ch, CURLOPT_URL, "URL? ReqCode = gotoSearch & queryKind = 2 & postcode = ". $ zip ); Curl_setopt ($ ch, CURLOPT_HEADER, true ); Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true ); Curl_setopt ($ ch, CURLOPT_POST, true ); Currochelle setopt ($ ch, CURLOPT_CONNECTTIMEOUT, 120 ); Curl_setopt ($ ch, CURLOPT_REFERER, $ refer ); Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ headers_login ); Curl_setopt ($ ch, CURLOPT_COOKIEFILE, $ cookie_jar ); Curl_setopt ($ ch, CURLOPT_COOKIEJAR, $ cookie_jar ); Curl_setopt ($ ch, CURLOPT_USERAGENT, $ _ SERVER ['HTTP _ USER_AGENT ']); Curl_setopt ($ ch, CURLOPT_POST, 1); // send a regular Post request Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ fields_string ); $ Data = curl_exec ($ ch ); Preg_match_all ('/id = "table1"> [s] *? <Tr> [s] *? <Td class = "maintext"> [sS] *? </Td> [s] *? </Tr>/', $ data, $ matches ); If (! $ Handle = fopen ($ filename, 'a + ')){ Echo "the file $ filename cannot be opened "; Echo "n "; Exit; } If (fwrite ($ handle, $ matches [0] [1]) === FALSE ){ Echo "cannot be written to file $ filename "; Echo "n "; Exit; } Echo "successfully writes $ somecontent to the file $ filename "; Echo "n "; Fclose ($ handle ); Curl_close ($ ch ); }   Class runtime { Var $ StartTime = 0; Var $ StopTime = 0; Function get_microtime () { List ($ usec, $ sec) = explode ('', microtime (); return (float) $ usec + (float) $ sec ); } Function start () { $ This-> StartTime = $ this-> get_microtime (); } Function stop (){ $ This-> StopTime = $ this-> get_microtime (); } Function spent () { Return ($ this-> StopTime-$ this-> StartTime ); } }   $ Runtime-> stop (); $ Con = 'processed in'. $ runtime-> spent (). 'seconds '; Echo 'processed in'. $ runtime-> spent (). 'seconds ';

Simulate a POST request to submit data or upload files.

.

The Code is as follows:

Copy code

Http://www.a.com/a.php Send POST request Function execUpload (){ $ File = '/doucment/Readme.txt '; $ Ch = curl_init (); $ Post_data = array ( 'Loginfield' => 'username ', 'Username' => 'ybb ', 'Password' => '123 ', 'File' => '@ d: usrwwwtranslatedocumentReadme.txt' ); Curl_setopt ($ ch, CURLOPT_HEADER, false ); // When enabled, a conventional POST request will be sent. The type is application/x-www-form-urlencoded, just like form submission. Curl_setopt ($ ch, CURLOPT_POST, true ); Curl_setopt ($ ch, CURLOPT_BINARYTRANSFER, true ); Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ post_data ); Curl_setopt ($ ch, CURLOPT_URL, 'HTTP: // www. B .com/handleUpload.php '); $ Info = curl_exec ($ ch ); Curl_close ($ ch ); Print_r ($ info ); } 2. http://www. B .com/handleUpload.php Function handleUpload (){ Print_r ($ _ POST ); Echo '= file upload info :'; Print_r ($ _ FILES ); }
