Python Azure：ssl.SSLEOFError：EOF 发生违反协议 (_ssl.c:2427)

Question

我有以下 Flask 应用程序代码：

def do_binance_trading(queue): 
    print("Going to start a socket. . .")
    socket_manager = BinanceSocketManager.getInstance() 
    socket_manager.startSocket(queue) 
    print("Socket started. . .")

@app.route("/") 
def main(): 
global process
global queue
global latestQueueData print("Ping app. . .")
if process is not None and process.is_alive():
    print("App is running. Trading process id:" + str(process.pid))    
    # Retrieve all data from the queue
    queue_data = []
    while not queue.empty():
        queue_data.append(queue.get())

    if len(queue_data) > 0 and latestQueueData != queue_data[-1]:
        latestQueueData = queue_data[-1]

    # Display all data in the queue
    return latestQueueData.replace("\n", "<br>"), 200
else:
    print("Starting App. . .")
    queue = multiprocessing.Queue()
    process = multiprocessing.Process(target=do_binance_trading, args=(queue,))
    process.start()
    print("Process started. . .")
    return "Trading started", 200

if name == "main": 
    app.run()

应用程序部署到 Azure Web 服务。逻辑非常简单：

1. 运行应用程序。流程开始
2. 根刷新时 - 从队列中获取进程的统计信息。

应用程序总体工作正常，但有时，在没有任何影响或逻辑的情况下，进程会终止，我得到以下 Azure 日志跟踪：

进程重新启动，应用程序继续运行，直到出现另一个异常。我有一种感觉，我缺少 Azure 中的某些配置。应用程序配置为“始终开启”

尝试了我可以在谷歌上搜索到的关于这个主题的所有内容，但没有运气

Answer 1

ssl.SSLEOFError：EOF 发生违反协议 (_ssl.c:2427)

为了避免上述错误消息，

确保您使用的是最新版本的库。

确保代码或 Azure 环境中没有可能过早关闭连接的超时设置。

我成功地将一个简单的 Flask 应用程序部署到 Azure 应用服务，没有任何问题。

应用程序.py

from flask import Flask
import multiprocessing
app = Flask(__name__)
process = None
queue = multiprocessing.Queue()
latestQueueData = ""
def do_binance_trading(queue): 
    print("Going to start a socket. . .")
    print("Socket started. . .")
@app.route("/") 
def main(): 
    global process
    global queue
    global latestQueueData 
    print("Ping app. . .")
    if process is not None and process.is_alive():
        print("App is running. Trading process id:" + str(process.pid))           
        queue_data = []
        while not queue.empty():
            queue_data.append(queue.get())
        if len(queue_data) > 0 and latestQueueData != queue_data[-1]:
            latestQueueData = queue_data[-1]   
        return latestQueueData.replace("\n", "<br>"), 200
    else:
        print("Starting App. . .")
        queue = multiprocessing.Queue()
        process = multiprocessing.Process(target=do_binance_trading, args=(queue,))
        process.start()
        print("Process started. . .")
        return "Trading started", 200
if __name__ == "__main__": 
    app.run()

本地输出：

我通过 Visual Studio 代码扩展部署了应用程序

部署后输出：
