问题描述
使用默认的Web API路线
With the default web api route
config.Routes.MapHttpRoute(
name: "API Default",
routeTemplate: "api/{controller}/{id}",
defaults: new
{
id = RouteParameter.Optional
}
);
和控制器
public class TestController : ApiController
{
[HttpGet]
public HttpResponseMessage Get(string id)
{
return Request.CreateResponse(HttpStatusCode.OK, id);
}
}
要请求API /测试/ 1
收益 1
如果由于某种原因,你发送一个请求到API /测试/ 1%20
If for some reason you send a request to 'api/test/1%20'
路线404的。
现在这个例子可能看起来很傻,因为浏览器修剪尾随空格,但
Now this example may seem silly since browsers trim trailing spaces, but
对于像路线API / {控制器} / {ID} / {} extrastuff
在 1
将转换成 1%20
和要求空间将404上路线不被发现。
the space in '1 '
would convert to '1%20'
and the request will 404 on the route not being found.
推荐答案
您的问题已无关的WebAPI本身,而是Asp.Net如何处理某些特定的URL。
而且Asp.Net在处理一个很偏执的方式这些URL,所以你需要告诉它to放松。
Your issue has nothing to do with WebAPI itself but how Asp.Net handles some specific urls.And Asp.Net handles these urls in a very paranoid way, so you need to tell it to relax.
这行添加到你的web.config在的System.Web
:
Add this line to your web.config under system.web
:
<httpRuntime relaxedUrlToFileSystemMapping="true" />

- Putting the Con (COM1, LPT1, NUL, etc.) Back in your URLs
同样在这样:
- 结尾的网址(它描述了一个不同的环境,所以我不认为这是一个真正的副本)
- "The resource cannot be found." error when there is a "dot" at the end of the url
- Problem with a URL that ends with %20 (it describes a different context so I don't think that this is a real duplicate)
