使用默认的 web api 路由
With the default web api route
config.Routes.MapHttpRoute( name: "API Default", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } );和一个控制器
public class TestController : ApiController { [HttpGet] public HttpResponseMessage Get(string id) { return Request.CreateResponse(HttpStatusCode.OK, id); } }对'api/test/1'
返回1
如果您出于某种原因向 'api/test/1%20' 发送请求
If for some reason you send a request to 'api/test/1%20'
路由 404.
现在这个例子可能看起来很傻,因为浏览器修剪了尾随空格,但是
Now this example may seem silly since browsers trim trailing spaces, but
对于像 'api/{controller}/{id}/{extrastuff}'
'1' 中的空格将转换为 '1%20' 并且请求将在未找到的路由上显示 404.
the space in '1 ' would convert to '1%20' and the request will 404 on the route not being found.
推荐答案您的问题与 WebAPI 本身无关,而是与 Asp.Net 处理某些特定 url 的方式有关.Asp.Net 以一种非常偏执的方式处理这些 url,因此您需要告诉它 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.
将此行添加到 system.web 下的 web.config:
Add this line to your web.config under system.web:
<httpRuntime relaxedUrlToFileSystemMapping="true" />您可以阅读有关此主题的更多信息:

也在 SO 上:
- "找不到资源.";有点"时出错在网址的末尾
- 网址以 %20 结尾的问题(它描述了一个不同的上下文,所以我不认为这是一个真正的重复)
- "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)
