这个错误提示是浏览器的跨域访问限制导致的。浏览器会发送一个预检请求(preflight request)先与目标服务器进行通信,确认服务器是否允许跨域访问。如果服务器返回的响应头中 Access-Control-Allow-Origin 的值为 *,并且请求的 withCredentials 属性为 true(表示带有凭证,如 Cookie 等),那么浏览器就会阻止该请求,因为这被认为是一种潜在的安全漏洞。
解决这个问题的方法是,需要在服务器的响应头中设置 Access-Control-Allow-Origin 的值为具体的域名,而不是 *,例如:
```
Access-Control-Allow-Origin: http://localhost:8080
```
这样就可以允许来自 http://localhost:8080 域名下的请求跨域访问了。如果需要允许多个域名下的请求跨域访问,可以在响应头中设置多个 Access-Control-Allow-Origin 的值,用逗号隔开即可。
