I am trying to do a get using http instead of https.

nrainsford Mar 21, 2018 1:53 AM

I have no issue with https from a web browser in when doing localhost on the same machine or from another machine. Is there a setting in the PI system explorer for enabling the use of http?

The reason I need to do this is because I am doing testing with Postman and cannot get a get https request to work. I want to try with http so I can monitor the traffic with wireshark and figure to figure out what the difference between the web browser get and Postman get is (because I have no issues with a get over the web browser).

I assume you are using PI Web API. The PI Web API is a RESTful interface to the PI system. It gives client applications read and write access to their AF and PI data over HTTPS.
The HTTPS encryption is mandatory and do not think there is a way around this.

You can investigate the issue by enabling Debug logs (In the Windows Event Log choose PI Web API & View > Show Analytic and Debug Logs) to capture the request-response behavior on your PI Web API server.
The error code in POSTMAN response can also help you to check why your request does not seem to work.

The above steps with the debug logs and PostMan error codes should suffice in troubleshooting the issue but if you wish to capture HTTPs traffic, you can use Fiddler to decrypt HTTPs traffic, but I strongly recommend its use only in a test environment.
