prerequisites:
- A locally runnable javaweb: mine is an online git springboot project
- Register a WeChat official account application link
Preparation before configuration - intranet penetration
Since the project is built on a local computer and cannot be accessed from the external network, a tool needs to be used to map the local address to the public network. Use of free tools: natapp
natapp download website
natapp configuration tutorial
Note: Only port 80 can be used here, because the WeChat official account is only open to port 80.
Free Tunnel Configuration
Register first, and log in after successful registration.
After the tunnel purchase is successful, you can see the existing tunnel in my tunnel:
client download
We visit the natapp client download, download the natapp client:
after downloading, unzip, there will be a natapp.exe file.
Before running
natapp, you need to configure it before running natapp. For detailed tutorials, please refer to: Using the local configuration file config.ini .
config.ini content:
Note: The config.ini configuration file needs to be in the same directory as natapp.exe.
Connection
After starting the javaweb project locally: access localhost:80,
double-click natapp.exe to run, and access your own connectionhttp://wge5gq.natappfree.cc/：80
Note: Since I am using springboot here, the default port is 8080, so I need to modify the port configuration in the configuration file application
Shut down the iis server: Internet Information Services
fails to configure because the iis of the win10 system occupies port 80 and needs to be closed
Steps : Control Panel -> Programs -> Enable or Disable Windows Features -> Cancel the 'Internet Information Services' option -> OKrequest verification
The WeChat public platform needs to send a request to the server to confirm the server connection.
This requires adding a separate request connection to the project
several parameters
Request verification code writing
- controller类：HelloWorldController.class
- Check interface consistency tool class: CheckoutUtil.class
