Passing a List to an MVC Web API method us

问题:

I have an MVC Web API Get method that accepts a List<string> as a parameter. I'm trying to access this method using simply the browser bar. How is this done? Using ../APIName?parameter1=value1&parameter2=value2&... passes a single parameter between two ampersands as opposed to a list.

回答1:

1. Make sure your parameter of your action method is marked as [FromUri]. By default the value is expected to be passed from the body of the request since it is a complex type.

   public List<string> Get([FromUri] List<string> parameter)
   {...}
   

2. The query string parameter should be of this format .../APIName?parameter[]=value1&parameter[]=value2&....

Hope this helps.
