Question

我的webapp（php，kohana 2.x）有问题，我真的不知道如何解决它。这只发生在一些用户身上，无论如何，我都无法通过更改浏览器来复制它。通常，登录表单正在运行，但有时会发送NULL post：

language en_US
2012-01-07 19:55:24 +01:00 --- info: Called login, but POST is empty.
2012-01-07 19:55:24 +01:00 --- info: <pre>(array) Array
(
)
</pre>
2012-01-07 19:55:24 +01:00 --- info: <pre>(array) Array
(
)
</pre>

这是表格代码：

<div id="form">

<form action="/index.php/user/login" method="post">
<input type="text" id="username" name="username"  style="width:140px">
<input type="password" id="password" name="password"  style="width:140px">
<input type="submit" id="submit" value="Enter" class="submit"  />           
</form>

</div>

任何线索？

感谢。

Answer 1

我了解到有些浏览器插件正在执行用户正在访问的其他请求链接。

一个示例是Chrome插件，它在地址栏中显示一些服务器标头，插件正在向服务器发送其他请求以读取标头信息，在用户不知情的情况下生成第二个请求。我的网上银行和几个基于cookie的会话处理网站因此而破产。

要确定问题的根源，您应该记录尽可能多的数据，例如对该链接的请求的完整$ _SERVER和$ _REQUEST数组。为了更好地理解这种情况，您应该将分析与Web服务器日志文件结合起来，以便在“null”提交之前查看同一客户端发送给服务器的所有其他请求。

Answer 2

我认为Kohana不应该归咎于此。我在Apache / PHP设置中看到过相同的内容。在某些情况下，如果在对服务器的请求中未正确设置标头，则$ _POST为空。

在这些情况下，请查看来自felixsigl的代码片段，将原始http输入转换为$ _POST

PHP some $_POST values missing but are present in php://input

Answer 3

尝试在表单操作中添加“/”：

<form action="/index.php/user/login/" method="post">

表单发送空POST（有时）
