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
}
);
还有一个控制器
public class TestController : ApiController
{
[HttpGet]
public HttpResponseMessage Get(string id)
{
return Request.CreateResponse(HttpStatusCode.OK, id);
}
}
对'api/test/1'
返回 1
如果由于某种原因您向 'api/test/1%20'
发送请求
If for some reason you send a request to 'api/test/1%20'
404 路线.
现在这个例子可能看起来很傻,因为浏览器会修剪尾随空格,但是
Now this example may seem silly since browsers trim trailing spaces, but
对于像 'api/{controller}/{id}/{extrastuff}'这样的路由
'1 '
中的空格将转换为 '1%20'
并且请求将在找不到路由上出现 404.
the space in '1 '
would convert to '1%20'
and the request will 404 on the route not being found.
您的问题与 WebAPI 本身无关,而是 Asp.Net 如何处理一些特定的 url.而 Asp.Net 以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.
在 system.web
下将此行添加到您的 web.config:
Add this line to your web.config under system.web
:
<httpRuntime relaxedUrlToFileSystemMapping="true" />
