Current Behavior

After the forward-auth verification is passed, the upstream cannot obtain the request body (payload)

getData2 can be called normally, but getData() doesn't, and after many tests I think there are no parameters in the payload

This screenshot shows the error on the C# backend

(GetData call failure occurs only when forward-auth is used, and can be called normally if it is not used)

Here's my Foward-auth configuration:
"forward-auth": {
"_meta": {
"disable": false
},
"client_headers": [
"apk",
"timestamp",
"nonce",
"sign",
"Content-Length",
"Expect",
"Transfer-Encoding",
"Content-Encoding"
],
"request_headers": [
"apk",
"timestamp",
"nonce",
"sign",
"Content-Length",
"Expect",
"Transfer-Encoding",
"Content-Encoding"
],
"request_method": "POST",
"status_on_error": 500,
"upstream_headers": [
"apk",
"timestamp",
"nonce",
"sign",
"Content-Length",
"Expect",
"Transfer-Encoding",
"Content-Encoding"
],
"uri": "http://localhost:9080/authApi/api/authorization/authorization1"
},

other QS：forward-auth's configuration request_method:"GET" will result in an error: “time out”. Like mentioned in #11021,How can I avoid these issues in apisix-docker?

Expected Behavior

I hope that when using the forward-auth plugin, my request will be successfully requested to my upstream

Steps to Reproduce

1. Run APACHE/APISIX the Docker image.
2. Create a Route with the API.
3. Configure the forward-auth for the route
4. Test external certification
5. Test the access route and observe whether the request enters the upstream backend
6. The test found that the request successfully passed the external authentication and was forwarded to the upstream, but an error occurred
