Issue
I have created some curl command to send a POST to my server where I am listening on that port for input to trigger additional action. The command is the following (Just masked the URL):
curl -v -H "Content-Type: application/json" -X POST -d "{\"Location\":\"Some Name\",\"Value\":\"40%\"}" http://example.com:8885/
I get the following output from curl:
About to connect() to example.com port 8885 (#0)
Trying 5.147.XXX.XXX...
Connected to example.com (5.147.XXX.XXX) port 8885 (#0)
POST / HTTP/1.1
User-Agent: curl/7.29.0
Host: example.com:8885
Accept: /
Content-Type: application/json
Content-Length: 40
upload completely sent off: 40 out of 40 bytes
However after that curl does not close the connection. Am I doing something wrong? Also on the server I only receive the POST as soon as I hit ctrl+c.
Solution
It sits there waiting for the proper HTTP response, and after that has been received it will exit cleanly.
A minimal HTTP/1.1 response could look something like:
HTTP/1.1 200 OK
Content-Length: 0
... and it needs an extra CRLF after the last header to signal the end of headers.
