Playing with Buffalo Cloud: HTTP API Realizes Wechat Message Reminder
foreword
This article will introduce how to use the HTTP API and WeChat developer tools to realize the function of sending message reminders from the MCU controller to the WeChat account. The HTTP API used in this article is provided by the Baffa cloud platform and is used to access and control remote hardware devices.
Step 1: Create a Baffa Cloud account
First, you need to register an account (https://www.byfycloud.com/) on the official website of Buffalo Cloud and log in. After successful registration, you can create a new project and add a new device. For the convenience of testing, you can choose a general-purpose development board such as Raspberry Pi or ESP32.
Step 2: Create an HTTP API key
Next, we need to create an HTTP API key so that your program can use the HTTP API to make calls to remote devices. From the Buffalo Cloud project management page, click the API Keys tab, then click New API Key. Set the API key name and save it.
Step 3: Install Flask and Requests library
Next, we need to write a simple web server using Python to receive the HTTP POST request sent from the device and send the message to WeChat. For this, we need to install Flask and Requests library. These libraries can be installed in Terminal or Command Prompt with the following commands:
pip install Flask
pip install requests
Step 4: Write a Python script
In this step, we will write a Python script to listen to the HTTP POST requests sent by the device and send notifications through WeChat messages. First, make sure you have created a Buffalo Cloud project and added a device. Then, save the following code as "app.py":
