debug rest call in wso2 api manager

Question

I am connecting rest api call with wso2 api manager. I followed the steps from wso2 site

I am able to connect with rest api on my computer but following same procedure on another computer returns "Error: No Response from Server"

I had also configured the files as described here

Does anybody knows how to debug what is going wrong there ?

Answer 1

You can enable wirelogs and headers in API Manager to analyze the request response flow.

1. Open log4j.properties file in /repository/conf directory.

2. Uncomment the following loggers.

   log4j.logger.org.apache.synapse.transport.http.headers=DEBUG log4j.logger.org.apache.synapse.transport.http.wire=DEBUG

3. Save the changes and Restart the Server

4. Invoke the API.

Regarding your "Error: No Response from Server" response, other than the CORS issue, this can occur due to browser certificate issue as well.

Therefore, first check whether you can invoke the same API using a rest client like curl,

if yes go to your browser, accept the certificate for the gateway URL and try out invoking the API again.
