Kivy Buildozer：aiohttp 异步问题，应用程序崩溃

问题描述 投票：0回答：1

我会尝试准确地解释我的问题。 首先，我的 kivy 应用程序及其所有部分都可以在 VScode 中运行。 这是一个计算器应用程序，可以抓取一些数据并计算它们

Python版本：3.11.7 Kivy版本：2.3.0

我的代码中有两个函数，所以我希望它们同时协同工作，所以我使用了 aiohttp asyncio。开始吧

我在应用程序中使用的库

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label
from kivy.uix.image import Image
from kivy.uix.behaviors import ButtonBehavior
from kivy.metrics import dp
from kivy.clock import mainthread
from kivy.uix.popup import Popup
from kivy.factory import Factory
from kivy.properties import ObjectProperty
from time import sleep
from unidecode import unidecode
from bs4 import BeautifulSoup
import aiohttp
import asyncio
import requests
import threading
import re

aiohttp / asyncio 的代码示例

@mainthread
    def calculate(self, lig, *args):


        async def fetch_stats_home(session, url, match_codes_home):
            try:
                querystring = {}
                headers = {}

                async with session.get(url, params=querystring, headers=headers) as response:
                    
                    soup = BeautifulSoup(await response.text(), "html.parser")

                
           
        async def fetch_stats_away(session, url, match_codes_away):

            try:
                querystring = {}
                headers = {}

                async with session.get(url, params=querystring, headers=headers) as response:

                    soup = BeautifulSoup(await response.text(), "html.parser")                  

            except:
                pass         

        async def main():
            url = "https://Handler.aspx"    
            match_codes_home = evsahibi_evindeki_maclar_kodlar
            match_codes_away = deplasman_deplasmandki_maclar_kodlar  

            async with aiohttp.ClientSession() as session:
                tasks_home  = [fetch_stats_home(session, url, match_code) for match_code in match_codes_home]
                tasks_away  = [fetch_stats_away(session, url, match_code) for match_code in match_codes_away]
                await asyncio.gather(*tasks_home, *tasks_away)

        asyncio.run(main())

VSCODE 测试和终端日志（应用程序运行没有问题）

APP WORKS

BUILDOZER：我在 Buildozer 中编译了应用程序，当我单击“计算”按钮时，应用程序崩溃了。

这是日志：adb logcat -s python

正如你所看到的，在第一次[使用proactor] IocpProactor时，APP崩溃了。

Buildozer.spec

requirements = python3==3.11.7,kivy==2.3.0,aiohttp==3.9.3,aiosignal==1.3.1,attrs==23.2.0,beautifulsoup4==4.12.3,certifi==2024.2.2,charset-normalizer==3.3.2,docutils==0.20.1,frozenlist==1.4.1,idna==3.6,multidict==6.0.5,requests==2.31.0,soupsieve==2.5,Unidecode==1.3.8,urllib3==2.2.0,yarl==1.9.4

osx.python_version = 3.11.7
osx.kivy_version = 2.3.0

更新发现问题但无法修复

当我通过 buildozer 创建 APK 时，我检查了 “buildozer android 调试部署运行 logcat” '与 session.get(url, params=querystring, headers=headers) 异步作为响应：' 部分不起作用，里面的 beautifulsoup 也不起作用，所以数据不会被刮掉！我们得到 ZeroDivisionError

但是在VSCODE中没有问题。

为什么 'async with session.get(url, params=querystring, headers=headers) 作为响应：' 部分在 kivy 中不起作用？

谢谢

首先我检查了

async with session.get(url, params=querystring, headers=headers) as response:
处的错误，因为它没有执行

try:
    async with session.get(url, params=querystring, headers=headers) as response:
        print("mecra")  # Add this line
        soup = BeautifulSoup(await response.text(), "html.parser")
except Exception as e:
    print(f"Exception: {e}")

错误是：

无法连接到主机 .com:443 ssl:True [SSLCertVerificationError: (1, '[SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败:

我从chatgpt获得帮助：

现在我将 ssl 导入到 python 中

新代码

ssl_context = ssl.create_default_context()
ssl_context.check_hostname = False
ssl_context.verify_mode = ssl.CERT_NONE
async with session.get(url, params=querystring, headers=headers, ssl=ssl_context) as response:

现在

async with session.get(url, params=querystring, headers=headers) as response:
执行并且我的代码可以工作:)
