@tzssangglass 我只有这一个插件，只是设置了两个自定义变量。
ky-ngx-vars.py
```lua
local ngx = ngx
local core = require("apisix.core")
local schema = {
type = "object",
properties = {},
required = {}
}
local metadata_schema = {
type = "object",
properties = {},
required = {}
}
local plugin_name = "ky-ngx-vars"
local _M = {
version = 0.1,
priority = 0, -- TODO: add a type field, may be a good idea
name = plugin_name,
schema = schema
}
function _M.check_schema(conf, schema_type)
if schema_type == core.schema.TYPE_METADATA then
return core.schema.check(metadata_schema, conf)
end
return core.schema.check(schema, conf)
end
function _M.before_proxy(conf, ctx)
ngx.var.route_name = ctx.matched_route.value.name
ngx.var.upstream_name = ctx.matched_upstream.name
core.log.debug("set $route_name=", ngx.var.route_name)
core.log.debug("set $upstream_name=", ngx.var.upstream_name)
end
return _M
```
