如何将查询字符串参数转换为看起来像 ASP.NET Core 的目录部分？

Question

I have an application that is written using C# on the top of the ASP.NET Core 3.1 framework.

Typically, Http Get request generates a URL with parameters to look something like this

/for_sale/Virginia_Heights/WV?beds=3+&type=MULTI-FAMILY,SINGLE-FAMILY_HOME_type

However, I want a way to convert the previous URL to look something like the following instead

/for_sale/Virginia_Heights/WV/3+_beds/MULTI-FAMILY,SINGLE-FAMILY_HOME_type

Trulia has done something like this on their website (ie, https://www.trulia.com/for_sale/Virginia_Heights,WV/3p_beds/MULTI-FAMILY,SINGLE-FAMILY_HOME_type/ )

If you go to the previous URL and change the filter, you'll notice that any filter you chose will add that filter to the URL as a directory without adding ?=... query parameters.

I am guessing the URL generation and data fetching are happening using the AJAX technique with the help of Javascript. Isn't it? Or, could there be a better way to handle the URL generation?

The part I am struggling with here is building a flexible route in ASP.NET Core that would handle multiple optional parameters.

Question How can I create a route in ASP.NET Core that would allow me to handle such a request with many optional parameters to look like the example above?

Answer 1

You have to set the route like this:

[Route("/for_sale/Virginia_Heights/WV/{beds}/{type}]
public IActionResult GetPropertyInfo(string beds, string type)
{
   // .....
}

/for_sale/Virginia_Heights/WV of course is not part of the answer. It's whatever your domain and other url structure may be.

Answer 2

It can be done by writting the controller method like below.We can specify that the beds and type parameter is from the route using the attribute [FromRoute].

 [Route("/for_sale/Virginia_Heights,WV/{beds}/{type}] public IActionResult GetPropertyInfo([FromRoute]string beds, [FromRoute]string type) { // do something } We can also specify other model into it using [FromBody] atrribute. [Route("/for_sale/Virginia_Heights,WV/{beds}/{type}] public IActionResult GetPropertyInfo([FromRoute]string beds, [FromRoute]string type,[FromBody]Home model) { // do something }
