Can't test my api on local server, always redirect to google api. After migrate to endpoints 2.0

Question

All had good on endpoints 1.0. I've done all steps at migrating 2.0 google docs. Update my project successfully, and can run endpoints api explorer. But when I try run endpoints api explorer locally (localhost:8080/_ah/api/explorer) it's redirect me to google api explorer. This my app.yaml

Answer 1

Redirecting to the Google APIs Explorer is the correct behavior, but given that you are using HTTP for localhost, it prevents you from seeing your API.

There are two fixes that I've found:

1. See this link for details on how to restart your browser to allow this content.
2. If you're using Chrome, click on the shield in the address bar and choose "Load Unsafe Scripts". (see below)
