javascript - WebAPI 提取是否遵循重定向？

Question

是否fetch遵循 HTTP 30x 重定向？

Answer 1

是的。 Check this .

Checking to see if the response comes from a redirected request is as simple as checking this flag on the Response object.

 if (response.redirected) {
   //...
 }

您可以禁用它:

fetch("awesome-picture.jpg", { redirect: "error" }).then(function(response) {
  //some stuff
}).then(function(imageBlob) {
  //some other stuff
});
