问题描述
好的，
我正在使用 System.Runtime.Serialization 和 DataContractJsonSerialization.
问题是在请求中我发送了一个带有 & 字符的属性值.比如说，AT&T，我得到一个错误响应:Invalid JSON Data.
The problem is that in the request I send a value of a property with the & character. Say, AT&T, and I get a response with error: Invalid JSON Data.
我认为转义将在库内完成，但现在我看到序列化未触及&符号 & 字符.
I thought that the escaping would be done inside the library but now I see that the serialization is left untouched the ampersand & character.
是的，对于 JSON 格式，这是有效的.但这对我的 POST 请求来说是个问题，因为我需要将它发送到一个服务器，如果该服务器包含一个&符号，则会出现错误响应，因此我在这里.
Yes, for a JSON format this is valid.But it will be a problem to my POST request since I need to send this to a server that if contains an ampersand will response with error, hence here I am.
HttpUtility.HtmlEncode 在 System.Web 库中，所以要走的路是使用 Uri.EscapeUriString.我这样做是为了尝试，但无论如何，如果没有它，所有请求都可以正常工作，除了一个&符号在一个值中.
HttpUtility.HtmlEncode is in the System.Web library and so the way to go is using Uri.EscapeUriString. I did this to try, but anyway, and without it all requests are working fine, except an ampersand is in a value.
HttpUtility 类已移植到 Windows Phone SDK，但编码字符串的首选方法仍应为 Uri.EscapeUriString.
HttpUtility class is ported to the Windows Phone SDK but the prefer way to encode a string should be still Uri.EscapeUriString.
首先想到的是弄脏手并开始替换会导致服务器出现问题的特殊字符，但是，我想知道我应该做的另一种解决方案是高效且正确"的吗?
First thought was to get hands dirty and start replacing the special character which would cause a problem in the server, but, I wonder, is there another solution I should do, that it would be efficient and 'proper'?
我应该说我使用
// Convert the string into a byte array.
byte[] postBytes = Encoding.UTF8.GetBytes(data);
将 JSON 转换为 byte[] 并写入 Stream.还有，
To convert the JSON to a byte[] and write to the Stream.And,
request.ContentType = "application/x-www-form-urlencoded";
作为 WebRequest.ContentType.
那么，我是因为某种原因还是我想念的事情搞砸了?
So, am I messed up for a reason or something I miss?
谢谢.
推荐答案
问题是我正在对包括键在内的整个请求字符串进行编码.我有一个请求 data={JSON} 并且我正在格式化它，但是 {JSON} 部分应该只被编码.
The problem was that I was encoding the whole request string including the key.I had a request data={JSON} and I was formatting it, but the {JSON} part should only be encoded.
string requestData = "data=" + Uri.EncodeDataString(json) // worked perfect!
要进入的愚蠢洞.
