ASP.NET MVC读取原始JSON数据后 [英] ASP.NET MVC Read Raw JSON Post Data
问题描述
这是推动我疯了。我使用ASP.NET MVC。我有与作为由另一台服务器（不在我的控制）调用的回调URL的HttpPost作用的控制器。我想动态读取JSON张贴到它，而无需使用的WebAPI或模型绑定。该网址也有传递给它的查询字符串参数。
This is driving me crazy. I'm using ASP.NET MVC. I have a controller with an HttpPost action that acts as a callback URL that is called by another server (not under my control). I want to dynamically read JSON posted to it without using WebAPI or Model Binding. The URL also has a query string parameter passed to it.
回调URL看起来是这样的：
The callback URL looks something like this:
http://domain.com/callback?secret=1234
我试着阅读使用贴输入：
I've tried reading the posted input using:
[HttpPost]
public ActionResult Callback( String secret )
{
String jsonData = new StreamReader(this.Request.InputStream).ReadToEnd();
// ...
}
不过jsonData始终为空或空。
However "jsonData" is always null or empty.
我只是想获得张贴的输入，将其放入JsonFx这样我就可以动态访问的内容。如何做到这一点的最简单的方式任何想法？
I just want to get the posted input and stick it into JsonFx so I can dynamically access the contents. Any ideas on how to do this the easiest possible way?
更新
我发现下面的...
虽然上述不起作用（jsonData将为空或空），则下列情况，如果我什么配置的小选项我有呼叫服务器上，从而忽略了秘密查询字符串参数，这是所有我可以为此做的，因为它不是我的服务器。在这种情况下，jsonData将具有正确的贴JSON字符串
While the above DOES NOT work (jsonData will be null or empty), the following DOES if I configure what little options I have on the calling server so as to omit the "secret" query string parameter, which is about all I can do on that end since it is not my server. In this case, jsonData will have the correct posted JSON string:
[HttpPost]
public ActionResult Callback( /* String secret */ )
{
String jsonData = new StreamReader(this.Request.InputStream).ReadToEnd();
// ...
}
这是很无奈的解决，我不知道一个简单的方法来同时接受查询字符串并张贴了标准的MVC控制器上的JSON数据。
This is very frustrating to work around and I don't know an easy way to accept both a query string and posted JSON data on a standard MVC controller.
我有一个回调控制器与行动方法接受各种数据（通过GET，通过表单POST，通过JSON POST，通过JSON POST瓦特/查询字符串，等等）从不同的第三方服务器。这些商人型的回调，我有超过用来传递信息的格式或方法无法控制的。我只需要接受回调和处理应该在那里的信息。
I have a "callback controller" with Action methods that accept various data (via GET, via form POST, via JSON POST, via JSON POST w/ a Query String, etc.) from different third-party servers. These are merchant-type callbacks where I have no control over the formats or methods used to convey information. I just need to accept the callbacks and process the information that should be there.
在我的控制器所有这一切工作正常，但中JSON POST瓦特/查询字符串的情况。
All of it works fine in my Controller, except the case of "JSON POST w/ a Query String".
此出现（至少对我来说）是在标准的ASP.NET MVC控制器的一个缺点。 ???
任何人都可以提出一个解决的办法，可以在一个标准的ASP.NET MVC控制器一起使用？
Can anyone suggest a solution to this that can be used in a standard ASP.NET MVC controller?
推荐答案
如果你考虑到一个事实，即ASP.NET MVC模型绑定已读取流，所以你应该倒带你最初的做法应该工作：
Your initial approach should work if you take into consideration the fact, that ASP.NET MVC model binding has already read the stream, so you should rewind it:
[HttpPost]
public ActionResult Callback(string secret)
{
Request.InputStream.Seek(0, SeekOrigin.Begin);
string jsonData = new StreamReader(Request.InputStream).ReadToEnd();
// ...
}
