php模擬post行為代碼總結

GET行為比較簡單,POST比較復雜一些。這裡提供兩種方法供選擇:第一:手寫代碼。第二:利用HttpClient php類庫

第一種方法:

PHP代碼
<?PHP           
    $flag = 0;       
    //要post的數據        
$argv = array(       
     var1=>abc,        
     var2=>你好嗎);        
//構造要post的字符串        
foreach ($argv as $key=>$value) {        
     if ($flag!=0) {       
             $params .= "&";        
             $flag = 1;        
     }        
     $params.= $key."="; $params.= urlencode($value);        
     $flag = 1;        
     }        
     $length = strlen($params);       
         //創建socket連接        
     $fp = fsockopen("127.0.0.1",80,$errno,$errstr,10) or exit($errstr."—>".$errno);        
     //構造post請求的頭        
     $header = "POST /mobile/try.php HTTP/1.1";        
     $header .= "Host:127.0.0.1";        
     $header .= "Referer:/mobile/sendpost.php";        
     $header .= "Content-Type: application/x-www-form-urlencoded";        
     $header .= "Content-Length: ".$length."";        
     $header .= "Connection: Close";       
     //添加post的字符串        
     $header .= $params."";        
     //發送post的數據        
     fputs($fp,$header);        
     $inheader = 1;        
     while (!feof($fp)) {       
             $line = fgets($fp,1024); //去除請求包的頭隻顯示頁面的返回數據        
             if ($inheader && ($line == "
" || $line == "")) {       
                 $inheader = 0;        
             }        
             if ($inheader == 0) {        
                 echo $line;        
             }        
     }        
fclose($fp);        
?>       

第二種方法是:使用httpclient類

PHP代碼
$pageContents = HttpClient::quickPost(https://example.com/someForm, array(       
    name => Some Name,       
    email => email@example.com      
));   

使用httpclient類庫,可以去官方下載最新的類庫,官方地址為:https://scripts.incutio.com/httpclient/index.php

附加一些點php httpclient的其他幾個用法

靜態方法獲取網頁:

PHP代碼
$pageContents = HttpClient::quickGet(https://example.com/);     

Get方法獲取

PHP代碼
$client = new HttpClient(example.com);       
if (!$client->get(/)) {       
    die(An error occurred: .$client->getError());       
}       
$pageContents = $client->getContent();    

帶調試的Get方法獲取

PHP代碼
$client = new HttpClient(example.com);       
$client->setDebug(true);       
if (!$client->get(/)) {       
    die(An error occurred: .$client->getError());       
}       
$pageContents = $client->getContent();     

帶自動轉向的Get方法

PHP代碼
$client = new HttpClient(www.amazon.com);       
$client->setDebug(true);       
if (!$client->get(/)) {       
    die(An error occurred: .$client->getError());       
}       
$pageContents = $client->getContent();     

檢查頁面是否存在

PHP代碼
$client = new HttpClient(example.com);       
$client->setDebug(true);       
if (!$client->get(/thispagedoesnotexist)) {       
    die(An error occurred: .$client->getError());       
}       
if ($client->getStatus() == 404) {       
    echo Page does not exist!;       
}       
$pageContents = $client->getContent();     

偽造客戶端

PHP代碼
$client = new HttpClient(exa
