ShaunMaher opened a new issue, #11781:
URL: https://github.com/apache/apisix/issues/11781
### Current Behavior
If you configure Nginx to listen on a unix socket:
```yaml
nginx_config:
http_server_configuration_snippet: |
listen unix:/run/sockets/apisix_http;
```
And then make a request that is handled by the batch-requests plugin, you
get the following error:
```
connect to apisix failed: missing the port number
```
This is because the batch-requests plugin uses the `ngx.var.server_port`
variable when setting up the internal request, assuming that it is populated
with a port number. If the client connection came over a unix listening
socket, `ngx.var.server_port` is a zero length string.
### Expected Behavior
I get that unix sockets are probably an edge case but it would be nice if
this worked.
I will submit a PR shortly with my modified `batch-requests.lua` that checks
for this condition and then gets the `server_port` from the `node_listen`
property of the APISIX configuration.
### Error Logs
_No response_
### Steps to Reproduce
* Use the latest docker image
* Configure nginx (via apisix config.yml) to listen on a unix socket:
```yaml
nginx_config:
http_server_configuration_snippet: |
listen unix:/run/sockets/apisix_http;
```
* Configure the batch-requests plugin
* Issue a batch-request via the unix socket:
`curl --unix-socket /run/sockets/apisix_http http://127.0.0.1:9080/your_url
--data '{}'`
