问题 分析

根据提供的访问日志和nginx.conf配置文件分析，是循环重定向的问题。
配置中，location / 块使用了 try_files $uri $uri/ /index.html; 会导致导致在尝试访问根目录时发生重定向循环。
修改：添加一个新的location=/index块，直接提供 /index.html 而不进行重定向。

server {
    listen 80;
    server_name my_server_name;

    location / {
        root /usr/local/xxx_vue;
        index index.html index.htm;
        try_files $uri $uri/ /index.html;
    }

    location = /index.html {
        root /usr/local/xxx_vue;
    }

    location ^~ /api/ {
        proxy_pass http://xxx.xxx.xxx.xxx:8080/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}
