When i call my webservice witch takes two parameters i get:
当我打电话给我的网络服务时，我得到了两个参数：
A potentially dangerous Request.Path value was detected from the client (&).
从客户端 (&) 检测到潜在危险的 Request.Path 值。
Routeconfig:
路由配置：
config.Routes.MapHttpRoute(
name: "PropertiesSearch",
routeTemplate: "api/property/Search/{category}/{query}",
defaults: new { controller = "Property", action = "Search", category = "common", query = string.Empty }
);
Controllermethod:
控制器方法：

当我调用 api 时：
/api/property/search/homes/areaId%3D20339%26areaId%3D20015

A potentially dangerous Request.Path value was detected from the client (&).

Doing this:
这样做：
/api/property/search/homes/?query=areaId%3D20339%26areaId%3D20015
/api/property/search/homes/?query=areaId%3D20339%26areaId%3D20015
works fine.
工作正常。

Scott Hanselman blogged about this. You might want to check the requestPathInvalidCharactersproperty of the <httpRuntime>node in your web.config.
Scott Hanselman就此发表了博客。您可能需要检查web.config 中节点的requestPathInvalidCharacters属性<httpRuntime>。
Personally I would avoid such characters in the uri portion and simply put those values as query string parameters.
就我个人而言，我会避免在 uri 部分中使用此类字符，而只需将这些值作为查询字符串参数。
