Description
First, i write a http server without read request body and return code 400 and "Hello".
Then, set nginx upstream to the server,like
upstream up_nodes {
server 127.0.0.1:8080 max_fails=0;
}
Make a POST request with request body not null, and nginx will return 502 within a huge probability. I expect it will return code 400 and "Hello".
The error.log shows as below.
2017/05/14 14:23:31 [error] 34164#6456: *19 WSARecv() failed (10054: An existing connection was forcibly closed by the remote host) while reading response header from upstream, client: 127.0.0.1, server: ~.*, request: "POST / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "127.0.0.1"
If i make the same request to the upstream server directly, it will return as i expected.I grab the tcp packets and it shows the return body from upstream server is received by nginx but nginx don't return it to client.
