Question

以下代码将数据发送到测试页面，该测试页面只是var_dumps _REQUEST变量。页面没有得到post参数但获取了get参数。为什么会发生这种情况？

<?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

curl_setopt手册页中介绍了这些选项。 CURLOPT_POSTFIELDS提供的信息是：

要在HTTP“POST”操作中发布的完整数据。要发布文件，使用@预先添加文件名并使用完整路径。文件类型可以是通过跟随文件名中的类型明确指定 format'; type = mimetype'。此参数可以作为传递 urlencoded字符串，如'para1 = val1＆amp; para2 = val2＆amp; ...'或作为数组字段名称为键，字段数据为值。如果value是一个数组， Content-Type标头将设置为multipart / form-data。自PHP起 5.2.0，如果使用@前缀将文件传递给此选项，则value必须是数组。

所以我猜这不是这个：

CURLOPT_POSTFIELDS =>'jsonData='.$jsonData,

......你想要这样的东西：

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

Answer 2

尝试使用urlencode函数对字段的值进行编码，我还建议将标头添加到请求中以模拟表单请求，并将带有标头的数组传递给CURLOPT_HTTPHEADER选项，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'
   );

最近我还在下面附带的curl实用程序类中帮助测试某些表单，希望这会有所帮助：
