.Net Core Web API --Redirect to external url from Post Method

问题

Please advice how to redirect to external url from Post method using .Net core webapi. RedirectPermanent is not working.

public class RegisterUserController : Controller
{

  public async Task<RedirectResult> Post([FromBody] user)
    {
      ---somecode
        string url = "http://www.gmail.com";
        return RedirectPermanent(url) ;//--is not working
   }
}

回答1:

For redirect to specific URL use the RedirectResult class:

public async Task<ActionResult> Post([FromBody] user)
{
     //...
     string url = "http://www.example.com";
     RedirectResult redirectResult = new RedirectResult(url, true);
     return redirectResult;
}

The second parameter indicates whether the redirection should be permanent or not.
