将 text/xml 读入 ASP.MVC 控制器 [英] Reading text/xml into a ASP.MVC Controller

问题描述

如何将 text/xml 读入 ASP.MVC 控制器上的操作?

How do I read text/xml into an action on a ASP.MVC Controller?

我有一个 Web 应用程序，它可能会从两个不同的来源接收 POSTed Xml，因此 Xml 的内容可能不同.

I have a web application that may receive POSTed Xml from two different sources so the contents of the Xml may be different.

我希望我的控制器上的默认操作能够读取 Xml，但是我正在努力了解如何首先将 Xml 放入操作中.

I want the default action on my controler to be able to read the Xml however I am struggling to see how I can get the Xml into the action in the first place.

如果 Xml 是一致的，我可以使用模型绑定器，但在这里不可能.

If the Xml was consistent I could have used a Model Binder but thats not possible here.

推荐答案

您可以从请求流中读取:

You could read it from the request stream:

[HttpPost]
public ActionResult Foo()
{
    using (var reader = new StreamReader(Request.InputStream))
    {
        string xml = reader.ReadToEnd();
        // process the XML
        ...
    }
}

并且要清除此操作，您可以为 XDocument 编写自定义模型绑定器:

and to cleanup this action you could write a custom model binder for a XDocument:

public class XDocumentModeBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        return XDocument.Load(controllerContext.HttpContext.Request.InputStream);
    }
}

您将在 Application_Start 中注册:

ModelBinders.Binders.Add(typeof(XDocument), new XDocumentModeBinder());

最后:

[HttpPost]
public ActionResult Foo(XDocument doc)
{
    // process the XML
    ...
}

这显然更干净.
