启动vue项目验证码未显示错误

启动项目前段连接处报错 [pre] Request URL: http://localhost:8002/proxyApi//sys/login Request Method: POST Status Code: 504 Gateway Timeout Remote Address: 127.0.0.1:8002 Referrer Policy: no-referrer-when-downgrade [/pre] nginx中跳转前段utl地址的配置，启动nginx [pre] server { listen 80; server_name localhost; location / { root D:\IDEAprioject\renren-vue\renren-fast-vue; index index.html index.htm; } } # 启动Nginx后，访问如下路径即可 http://localhost } [/pre] 提问 nginx中html跳转失败的原因是什么呢
