PHP uses curl_init to initiate http requests to simulate login_PHP tutorial

There are two types of http requests, one is our ordinary http request login, and the other is another https request login. Let me introduce to you in detail how to use curl_init to implement http and https login.

Note: To use the curl_init function, this php extension must be turned on.

1. Open php.ini and enable extension=php_curl.dll
2. Check which directory the extension_dir value of php.ini is, and check whether there is php_curl.dll. If not, please download php_curl.dll, and then copy libeay32.dll and ssleay32.dll in the php directory to c:/windows/system32. .

Initiate http request

The code is as follows

Copy code

代码如下

复制代码

function _http_curl_post($url,$data) {     $ch = curl_init();     curl_setopt($ch, CURLOPT_URL, $url);     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);     curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 4);     curl_setopt($ch, CURLOPT_TIMEOUT,4);               if($data){         curl_setopt($ch, CURLOPT_POST, 1);         curl_setopt($ch, CURLOPT_POSTFIELDS, "value=".json_encode($data));  //请求参数转为json格式     }     curl_setopt($ch, CURLOPT_HEADER, false);     $string = curl_exec($ch);     curl_close($ch);     return $string; }

function _http_curl_post($url,$data)

{

$ch = curl_init();

代码如下	复制代码
$params = array(); $params['id']       = 1 $params['web_name']   = '好脚本'; $params['web_url']    = 'http://www.bKjia.c0m/'; $params['web_miaoshu']      = '脚本编程示例'; $data = _curl_post($url,$params); $arr =json_decode($data);

curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 4); curl_setopt($ch, CURLOPT_TIMEOUT,4);                                                                             If($data){ curl_setopt($ch, CURLOPT_POST, 1);           curl_setopt($ch, CURLOPT_POSTFIELDS, "value=".json_encode($data)); // Convert request parameters to json format } curl_setopt($ch, CURLOPT_HEADER, false); $string = curl_exec($ch); curl_close($ch); Return $string; }

Call method

The code is as follows	Copy code
$params = array(); $params['id'] = 1 $params['web_name'] = 'Good script'; $params['web_url'] = 'http://www.bKjia.c0m/'; $params['web_miaoshu'] = 'Script programming example'; $data = _curl_post($url,$params); $arr =json_decode($data);

In addition to the http request, there is also an https request. Last time I did a one-click login on Renren.com, and its interface was the https url. Using the above function, an error was reported. If you also encounter such a problem, you can refer to the following methods to solve it.

https request example

The code is as follows

代码如下

复制代码

function _https_curl_post($url, $vars)  {      foreach($vars as $key=>$value)     {         $fields_string .= $key.'='.$value.'&' ;     }      $fields_string = substr($fields_string,0,(strlen($fields_string)-1)) ;     $ch = curl_init();       curl_setopt($ch, CURLOPT_URL,$url);      curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);  // this line makes it work under https     curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);     curl_setopt($ch, CURLOPT_POST, count($vars) );     curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);          $data = curl_exec($ch);             curl_close($ch);               if ($data)     {         return $data;     }     else     {         return false;     } }

Copy code

function _https_curl_post($url, $vars)
{
foreach($vars as $key=>$value)
{
$fields_string .= $key.'='.$value.'&' ;
}  
$fields_string = substr($fields_string,0,(strlen($fields_string)-1));
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // this line makes it work under https
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POST, count($vars) );
Curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
$data = curl_exec($ch); $data = curl_exec($ch);
curl_close($ch);
                                 
If ($data)
{
         return $data;
}  
else
{
         return false;
}  
}
