问题
I am not able to send request payload to my POST service from WSO2.
On rest console, my service is working.
From WSO2 server I am able to do curl to my server with successful response.
here is my API configuration
Payload to send:
{"query":"Hi I am a POST query parameter"}
My server is receiving {} as request payload.
It expect RAW body in JSON (as above) in payload.
I have tried all combinations for Parameter Type, but still not able to send payload to my server from WSO2.
How can I do this?
EDIT 1 I have tried all possible ways of sending data including following. Am I doing something wrong here???
and
From both I get error that my payload is empty or incorrect!!
Edit 2
I am able to connect with Java based services but not with Python based services.
Do I need any special settings on my python server?
回答1:
enable wirelogs and check following
- payload is coming into the API manager (swagger -> AM )
- Payload is going out from api manager (AM -> backend)
Also check the request headers coming in and going out and compare them with the stuff from curl request (successful request)

I am using Flask and I am afraid Flask can not deal with this issue currently.
I could reproduce this issue, the message send to back-end correctly, but Python only handle message until timeout.
Python Flask cannot receive post request from WSO2
The work-round may be using Java or Python get method.

I solved this problem by using apache to proxy this request. I think this is related with wsgi. Processing chunked encoded HTTP POST requests in python (or generic CGI under apache)
ProxyPass / http://localhost:8001/
ProxyPassReverse / http://localhost:8001/
