nginx出错：rewrite or internal redirection cycle

原配置：location / {

        rewrite ^/(.*).html$ /$1.html?mode=test last;
        error_page 404 = @nodejs;
}



修改后：

location / {
root /path/to/files;
index index.html;
#try_files $uri /index.html;
if ($query_string !~ mode=test) {
rewrite ^/(.*).html$ /$1.html?mode=test redirect;
}
}
