带斜杠“/"的路由参数在网址中 [英] Route parameter with slash "/" in URL

问题描述

我知道您可以在路由属性中应用通配符以允许 / 例如日期输入:

I know you can apply a wildcard in the route attribute to allow / such as date input for example:

[Route("orders/{*orderdate}")]

通配符的问题只适用于URI中的最后一个参数.如果想拥有以下 URI，我该如何解决这个问题:

The problem with wildcard is only applicable to the last paramter in URI. How do I solve the issue if want to have the following URI:

[Route("orders/{orderdate}/customers")]

更新:

我知道通过重构代码来解决问题的方法很少，所以请不要提供类似以下的解决方案:

I know there are few options to solve the issue by refactoring the code so please do not offer a solution something like:

1. 将路由模板更改为[Route("orders/customers/{orderdate}")]
2. 将日期更改为不同的格式(例如 "dd-mm-yyyy")

推荐答案

@bet.. 我认为 genericUriParserOptions 不再适用于 .net 4.5 或更高版本..

@bet.. I think the genericUriParserOptions is no longer applicable to .net 4.5 or later..

另外，正如 @JotaBe 所建议的，您可能需要正确解码 url 请求.在大多数情况下，%2F 将自动转换为斜线 '/'.因此，如果您需要对其进行转义，则首先需要对 '%' 字符进行解码.因此您的 URL: 将类似于:www.domain.com/api/订单/23%252F06%252F2015/customers

Also as suggested by @JotaBe, you might need to correctly decode the url request. In most case the %2F will be automatically translated to a slash '/'. So if you need to escape it you will need to decode the '%' char in the first place.. so your URL: will look something like: www.domain.com/api/orders/23%252F06%252F2015/customers

注意字符 '%252F' 将被转换为实际的 '%2F'

Notice the characters '%252F' will be translated to the actual '%2F'

好的，这是完整的解决方案(已尝试并为我工作):

Ok here is the complete solution (Tried it and working for me):

1. 假设您有一个像这样的 API 端点:

1. Assuming you have an API endpoint like so:

[Route("orders/{date}/customers")]
public HttpResponseMessage Get(string date)
{
}

在 web.config 中，您需要将 requestPathInvalidCharacters 设置为空，这告诉 asp.net 允许所有请求

In the web.config you will need to set the requestPathInvalidCharacters to empty which tells the asp.net to allow all request

<system.web>
    <httpRuntime targetFramework="4.5" requestPathInvalidCharacters=""/>                
</system.web>
<system.webServer>
    <security>
      <requestFiltering allowDoubleEscaping="true" />
    </security>
</system.webServer>

当客户端向 API 发送请求时，您需要确保像这样转义 '%':

www.domain.com/api/orders/23%252F06%252F2015/customers

www.domain.com/api/orders/23%252F06%252F2015/customers

然后您需要对请求进行解码

You then need to decode the request

[Route("orders/{date}/customers")]
public HttpResponseMessage Get(string date)
{
        DateTime actualDate = DateTime.Parse(System.Net.WebUtility.UrlDecode(date)); // date is 23/06/2015
}
