比方说，我想打电话给一些服务器的方法，并把它传递以下JSON对象：

Let's say I want to call some server method and pass it the following JSON object:

var t = { "test": 0};

我用用下面的选项jQuery库$阿贾克斯方式：

I'm using jQuery library $.ajax method with the following options:

type: "POST",
async: true,
url: 'mypage.aspx?Action=myAction,
data: {
   test: JSON.stringify(t, null, 2)
},
contentType: 'application/x-www-form-urlencoded',
dataType: 'json',
.
.
.

在服务器端获取我用下面的code中的数据：

On the server side I fetch the data using following code:

  public string GetInputStream()
  {
     string inputContent;
     using (var sr = new System.IO.StreamReader(Request.InputStream))
        inputContent = sr.ReadToEnd();

     return Server.UrlDecode(inputContent.Split('=')[1]);
  }

当从其他浏览器比苹果的Firefox版本3.6.12，getInputStream方法返回名为：

When called from browsers other than Mac Firefox version 3.6.12, getinputstream method returns:

test=%7B%0A++%22test%22%3A+0%0A%7D

这是有效的，然后可以反序列化对象，但调用的时候 从Mac OS X 10.5.8的Firefox 3.6.12这个方法我不能反序列化的字符串：

which is valid and can then be deserialized into an object, but when calling this method from Mac OS X 10.5.8 Firefox 3.6.12 I got a string that cannot be deserialized:

test=%7B%0A++%22test%22%3A0%0A%Pr

我相信，在参数在字符串的结尾是搞乱了我，而不是变成一个右括号。任何想法？

I believe that the Pr at the end of the string is messing me up and not turning into a closing bracket. Any ideas?

编辑： 我一直在寻找的萤火虫网>通话> POST选项卡，惊讶地看到，POST字符串是有效的：测试=％7B％0A ++％22test％22％3A％220％22％0A％7D 还有什么地方可以这个帖子的字符串进行修改，在服务器与一个无效的字符串的到来？

I was looking at the Firebug Net > Call > POST tab and was surprised to see that the POST string is valid: test=%7B%0A++%22test%22%3A%220%22%0A%7D where else can this POST string be modified to arrive at the server with an invalid string?

EDIT2： 有趣的发现，一切问题都如果HTTPS（安全）的:-)用于解决。 我想这一定是在Mac上的Firefox中的安全设置？

Interesting finding, all problems are resolved if HTTPS (secure) is used :-). I guess it must be a security setting on Mac Firefox?

推荐答案

我觉得这是JQuery在Firefox AJAX错误在Mac上使用＆QUOT;管理和QUOT;用户

现在的问题是Firefox和在Mac OS X 10.5的家长控制功能之间的冲突。 POST数据的最后两个字符将被替换为镨。这个问题被首次报道，两年前，它看起来并不像它会被修复。

The problem is a conflict between Firefox and the parental controls in Mac OS X 10.5. The last two characters of the POST data are replaced with Pr. The problem was first reported two years ago, and it doesn't look like it will be fixed.

最好的工作，围绕我所知道的是，使用SSL，因为这似乎是prevent问题。如果这不是一个选项，那么你需要至少2个字符添加到您的POST数据的末尾，可忽略不计。在一个形式，这将意味着增加类似＆LT;输入类型=隐藏名称无用的价值=无​​用＆GT; 的形式结束（信贷米克尔Botanch ）。对于JSON / XML请求，最后几个人物是解析重要。如果你不能只是添加空格或新行（也许这会的工作，我没有尝试过），那么你需要添加一些其他的虚值的客户端。最后，服务器端你需要检测并删除这个多余的虚拟值（如克鲁尔的回答一样）。

The best work around I am aware of is to use SSL because that seems to prevent the problem. If that isn't an option, then you need to add at least 2 characters to the end of your POST data which can be ignored. In a form that would mean adding something like <input type="hidden" name "useless" value="useless"> to the end of the form (credit to Miquel Botanch). For JSON/XML requests, the last few characters are important for parsing. If you can't just add spaces or new lines (maybe that would work, I haven't tried), then you need to add some other dummy value client side. Finally, server side you'd need to detect and remove this extra dummy value (as krul's answer does).
