Issue description

my route :

{
    "uri": "/*",
    "host":"test.test.com",
    "upstream":
    {
        "type": "roundrobin",
        "scheme": "https",
        "pass_host": "rewrite",
        "upstream_host":"www.baidu.com",
        "nodes":
        {
            "112.80.248.76:443": 1
        }
    }
}

I expect when i visit test.test.com agent to www.baidu.com, but it is return 404.

Environment

• apisix version (cmd: apisix version): 2.10.3
• OS (cmd: uname -a):
• OpenResty / Nginx version (cmd: nginx -V or openresty -V):
• etcd version, if have (cmd: run curl http://127.0.0.1:9090/v1/server_info to get the info from server-info API):
• apisix-dashboard version, if have:
• the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner):
• luarocks version, if the issue is about installation (cmd: luarocks --version):

I expect to customize the route through the global plug-in, because the route information cannot be created through the apisix api. However, when the route does not match, it directly returns '404 route not found'.

Here is my pseudo code:

local nodes = {}
core.table.insert(nodes, { host ='112.80.248.76', weight = 1, port = 443 })
local up_conf = {
    type = "roundrobin",
    nodes = nodes,
    scheme = "https",
    pass_host = "rewrite",
    upstream_host = 'www.baidu.com'
}

local route_val = { uri = "/*", host = { host }, id = "#reverse_test" , upstream = up_conf }
ctx.matched_route = { value = route_val, modifiedIndex = 'test' }

Whether or not execute the plug-in before match runs?

404 route not found

This means that your request is not caught by any route, which I think might have something to do with your host settings.

Whether or not execute the plug-in before match runs?

global route run before route match.

My etcd doesn't have this route information.

in apisix 2.10.3 version, global route run after route match.

My etcd doesn't have this route information.

If this is business logic you wrote yourself, won't discuss it.

in apisix 2.10.3 version, global route run after route match.

Thank you for pointing that out, indeed.

ref to:

apisix/apisix/init.lua

Lines 388 to 396 in d9be046

	local route = api_ctx.matched_route
	if not route then
	-- run global rule
	plugin.run_global_rules(api_ctx, router.global_rules, nil)
	core.log.info("not find any matched route")
	return core.response.exit(404,
	{error_msg = "404 Route Not Found"})
	end

So I'm afraid you can't inject route when running the global plugin.

[kongjun01]

I see what you mean.

or maybe:

local route = api_ctx.matched_route
if not route then
    -- run global rule
    plugin.run_global_rules(api_ctx, router.global_rules, nil)

    route = api_ctx.matched_route
    if not route then
        core.log.info("not find any matched route")
        return core.response.exit(404,
                {error_msg = "404 Route Not Found"})
    end
end

the global plugin can set route.

        return core.response.exit(404,
                {error_msg = "404 Route Not Found"})
    end
end

the global plugin can set route.

If you need to do this, you can fork it and modify it later.
