我采用了 Keith Jackson 的解决方案并将其修改为：
a) 使用 asp.net web api 2 - 属性路由以及老派路由
和
b) 不仅要验证路由参数名称，还要验证它们的值
例如对于以下路线
[HttpPost]
[Route("login")]
public HttpResponseMessage Login(string username, string password)
{
...
}
[HttpPost]
[Route("login/{username}/{password}")]
public HttpResponseMessage LoginWithDetails(string username, string password)
{
...
}
您可以验证路由匹配正确的 http 方法、控制器、操作和参数：
[TestMethod]
public void Verify_Routing_Rules()
{
"http://api.appname.com/account/login"
.ShouldMapTo<AccountController>("Login", HttpMethod.Post);
"http://api.appname.com/account/login/ben/password"
.ShouldMapTo<AccountController>(
"LoginWithDetails",
HttpMethod.Post,
new Dictionary<string, object> {
{ "username", "ben" }, { "password", "password" }
});
}
