How to redirect user to a page after receiving the response from a fetch POST request?

问题

I am writing code for a web application that send a POST request to node.js server using fetch() api of javascript. On successful request server responds with a redirection, this redirection url is received in the fetch() api response body. After this what should I do to redirect user to this URL from fetch function.

fetch("/events/registration", {
          method: "POST",
          redirect:"follow",
          headers: {
            "Accept": "application/json , text/plain ,*/*",
            "Content-type": "application/json"
          },
          body: JSON.stringify({
            name,
            email,
          })
        })
.then((res)=>res.json())
.then((data)=>{console.log(data);if(data.err)alert(data.err);Response.redirect()});

In response that i receive in fetch api I am getting redirect:true , url: "LinkOfRedirection/redirect", now what should i do to redirect user from here to the LinkOfRedirection/redirect.

回答1:

// Sets the new location of the current window.
window.location = res.url;

// Sets the new href (URL) for the current window.
window.location.href = res.url;

// Assigns a new URL to the current window.
window.location.assign(res.url);

// Replaces the location of the current window with the new one.
window.location.replace(res.url);

// Sets the location of the current window itself.
self.location = res.url;

// Sets the location of the topmost window of the current window.
top.location = res.url;

Or you can use

res.redirect(301, res.url);
