请求提供基于PySimpleGUI的API心跳检测UI入门示例代码

Hey there! Since you're new to PySimpleGUI, I've whipped up a straightforward, easy-to-modify code example that fits your requirements perfectly. This will create a simple UI showing the status of two APIs, checking them every 5 minutes (300 seconds) and updating the display to "OK" or "NOT OK" based on the response.

import PySimpleGUI as sg
import requests
import time

def check_api_status(api_url):
    """Check if the API is reachable and returns a successful response"""
    try:
        # Send a GET request (adjust method/headers if your API needs it)
        response = requests.get(api_url, timeout=10)
        # Consider it OK if status code is in the 2xx range
        if 200 <= response.status_code < 300:
            return "OK"
        else:
            return "NOT OK"
    except Exception:
        # Any error (connection issue, timeout, etc.) means the API is unreachable
        return "NOT OK"

# Define the UI layout
layout = [
    [sg.Text("API 1 - ", size=(10, 1)), sg.Text("Loading...", key="-STATUS1-", size=(8, 1))],
    [sg.Text("API 2 - ", size=(10, 1)), sg.Text("Loading...", key="-STATUS2-", size=(8, 1))],
    [sg.Button("Exit", size=(10, 1))]
]

# Create the main window
window = sg.Window("API Heartbeat Monitor", layout)

# Set check interval (5 minutes = 300 seconds)
CHECK_INTERVAL = 300
last_check_timestamp = 0

# Main event loop
while True:
    # Check for events every 1 second to keep UI responsive
    event, values = window.read(timeout=1000)
    
    # Exit if window is closed or Exit button is clicked
    if event == sg.WIN_CLOSED or event == "Exit":
        break
    
    # Run API checks if the interval has passed
    current_time = time.time()
    if current_time - last_check_timestamp >= CHECK_INTERVAL:
        # Update status for API 1
        status_1 = check_api_status("https://your-api-endpoint-1.com/heartbeat")  # Replace with your URL
        window["-STATUS1-"].update(status_1)
        
        # Update status for API 2
        status_2 = check_api_status("https://your-api-endpoint-2.com/heartbeat")  # Replace with your URL
        window["-STATUS2-"].update(status_2)
        
        last_check_timestamp = current_time

# Clean up and close the window
window.close()

Key Details to Customize: #

• API Endpoints: Replace the example URLs in check_api_status() calls with your actual API heartbeat endpoints.
• Request Configuration: If your API requires POST requests, headers, or authentication, modify the requests.get() line (e.g., add headers={"Authorization": "Bearer YOUR_TOKEN"}).
• Check Frequency: Adjust CHECK_INTERVAL to change how often the APIs are checked (value is in seconds).
• Status Logic: Modify the check_api_status() function if you need to validate specific response content instead of just status codes.
