Rapid development of WeChat public platform using Golang (i): Turn on server configuration

This is a creation in Article, where the information may have evolved or changed.

The development of public platforms, in the end, is worthless, because the purpose of the public platform is to give people, there is no technical threshold, but the process is too much, recorded, hoping to help other people.

Find the Entrance

In the basic configuration menu, you can see the Modify Configuration button (which is really not found in the group).

Fill in the Parameters

If the server has already mapped the address to port 80 via nginx, it can be written like this (token and key have been replaced, of course).

Start rubbing code

In the document, the official wrote: The 3 parameters sorted in dictionary order, at first I was crazy, and later found that the language version of the sort ... Let's get to the next.

We add a route, this address is the URL that fills in the server configuration
Then add the Wxconnect.go file in the controllers

Re-run the project, click on the Settings page of the Submit button, should be able to display through, please carefully proofread parameters, copy and paste good.
At this point, the public platform has opened the door to you (remember to click the Enable button, otherwise the light verification through no eggs).
