ASP.NET MVC4的WebAPI和发布XML数据 [英] ASP.NET MVC4 WebAPI and Posting XML data

问题描述

我错过一招新的WebAPI - 我想通过POST请求提交XML字符串，并没有多少运气

I'm missing a trick with the new webapi - I'm trying to submit an xml string through a post request and not having much luck.

在前端使用jQuery这样的：

The front end is using jQuery like this:

    $(document = function () {
    $("#buttonTestAPI").click(function () {

        var d = " <customer><customer_id>1234</customer_id></customer>";
        $.ajax({
            type: 'POST',
            contentType: "text/xml",
            url: "@Url.Content("~/api/Customer/")",
            data: d,
            success: function (result) {
                var str = result;
                $("#output").html(str);
            }
        });
    });
});

我的控制器是pretty此刻简单 - 只是默认为后行动 - 试图返回什么传递：

My controller is pretty simple at the moment - just the default for the post action - trying to return what was passed in:

    public string Post(string value)
    {
        return value;
    }

不过，价值是反复空。奇怪的是，当我改变我的数据在jQuery来是这样的：

However, "value" is repeatedly null. The odd thing is, when I change my data in the jquery to be something like this:

d = "<customer_id>1234</customer_id>";

然后，我在我的控制器得到价值为1234。

Then I get "value" in my controller as 1234.

怎样才能在我的控制器访问更复杂的XML字符串？

How can I get access to the more complex xml string in my controller?

推荐答案

下面将让你通过POST到Web API方法读取原始XML消息：

The following will allow you to read a raw XML message via a POST to a Web API method:

public void PostRawXMLMessage(HttpRequestMessage request)
{
   var xmlDoc = new XmlDocument();
   xmlDoc.Load(request.Content.ReadAsStreamAsync().Result);   
}

您可以调试和检查身体，头部等，并会看到原始的XML发布。我用小提琴手的作曲家做出HTTP POST，这工作得很好。

You can debug and inspect the body, headers, etc. and will see the raw XML posted. I used Fiddler's Composer to make a HTTP POST and this works well.
