推荐答案

它看起来像是CORS错误，您正在从本地主机上的本地计算机到其他URL上的后端执行http请求.解决此问题的唯一方法是允许后端发出来自不同来源的请求.或者可能在您的本地计算机上运行后端.

It looks like a CORS error, you are doing the http request from your local machine on localhost to the backend on a different URL. The only way to solve this would be to allow requests from different origins on the backend. Or possibly to run the backend on your local machine.
