具体的配置

nginx.conf

server {
        listen       80;
        server_name  orange.com;

        location = /favicon.ico {
            log_not_found off;
            access_log off;
        }

        location / {
            set $upstream_host $host;
            set $upstream_request_uri '';
            set $upstream_url '';
            set $upstream_scheme '';
            set $target '';

            rewrite_by_lua_block {
                local orange = context.orange
                orange.redirect()
                orange.rewrite()
            }

            access_by_lua_block {
                local orange = context.orange
                orange.access()
            }

            # proxy
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Scheme $scheme;
            proxy_pass $upstream_scheme$upstream_url$upstream_request_uri;

            header_filter_by_lua_block {
                local orange = context.orange
                orange.header_filter()
            }

            body_filter_by_lua_block {
                local orange = context.orange
                orange.body_filter()
            }

            log_by_lua_block {
                local orange = context.orange
                orange.log()
            }
        }

        location /robots.txt {
            return 200 'User-agent: *\nDisallow: /';
        }
    }

dashbord中规则如下

{
  "name": "appdata",
  "judge": {
    "type": 0,
    "conditions": [
      {
        "type": "URI",
        "operator": "match",
        "value": "appdata"
      }
    ]
  },
  "extractor": {
    "type": 1,
    "extractions": []
  },
  "handle": {
    "uri_tmpl": "/api/appdata",
    "log": true
  },
  "enable": true
}

期望的结果

浏览器访问：http://orange.com/appdata 日志报错

从日志可见，URL确实被重写了，但是最终这个invalid URL prefix in ""，我查找了源码，没有找到原因，希望帮忙解答，thanks
