php curl post數據不被接收

Question

下面的代碼發送數據到一個測試頁面，只是var_dumps _REQUEST變量。頁面沒有得到post參數，但獲取get參數。爲什麼發生這種情況？

<?php 
    $jsonData = '{"Page":"index.html","KeyNumber":12132321}'; 
    $timeout = 20; 
    $options = array(
     CURLOPT_URL => "http://myadmin/postdump.php?AID=100&age=5&ishide=0", 
     CURLOPT_RETURNTRANSFER => true, 
     CURLOPT_CONNECTTIMEOUT => $timeout, 
     CURLOPT_POST => true, 
     CURLOPT_POSTFIELDS =>'jsonData='.$jsonData, 
     CURLOPT_ENCODING=>"", 
     CURLOPT_FOLLOWLOCATION=>true 
     ); 

    $ch = curl_init(); 
    curl_setopt_array($ch, $options); 
    $file_contents = curl_exec($ch); 
    curl_close($ch); 

    echo $file_contents; 
?> 

Answer 1

這些選項在curl_setopt手冊頁中進行了說明。 CURLOPT_POSTFIELDS提供的信息是這樣的：

要在HTTP「POST」操作中發佈的完整數據。要發佈文件， 需要在文件名前添加@並使用完整路徑。文件類型可以是 ，其格式爲： 格式'; type = mimetype'。 此參數可以作爲 urlencoded字符串傳遞，如'para1 = val1 & para2 = val2 & ...'或作爲數組與 字段名稱作爲鍵和字段數據作爲值。如果value是一個數組，則 的Content-Type標題將被設置爲multipart/form-data。從PHP 開始5.2.0，如果使用@前綴將文件傳遞給此選項，則值必須是數組。

所以我想，與其這樣：

CURLOPT_POSTFIELDS =>'jsonData='.$jsonData, 

...你想是這樣的：

CURLOPT_POSTFIELDS => array('jsonData' => $jsonData), 

Answer 2

嘗試使用進行urlencode函數來編碼字段的值和我還建議將請求頭添加到請求中，以模擬將包含頭的數組傳遞給CURLOPT_HTTPHEADER選項的表單請求，例如

$headers = array(
     'Host: domain.com', 
     'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 
     'Accept-Encoding: gzip, deflate', 
     'Content-Type: application/x-www-form-urlencoded' 
    ); 

最近還我在下面附着在測試某種形式的幫助捲曲實用類的工作，希望這有助於：
