当我尝试使用 buildozer 构建 apk 时如何导入 urllib.request？

Question

我正在使用 kivy/python 构建应用程序。我所有的进口商品都符合我的 buildozer.spec 要求。当我添加 urllib 或 urllib.request 时，出现以下错误：

ould not fetch URL https://pypi.org/simple/urllib-request/: 404 Client Error: Not Found for url: https://pypi.org/simple/urllib-request/ - skipping

出了什么问题？如何在我的代码中使用 urllib.request？谢谢！

Answer 1

Kivy 有自己的实现 request/result 也许你可以用它代替 request/response

的 urllib

https://kivy.org/doc/stable/api-kivy.network.urlrequest.html

Answer 2

urllib 是一个标准库，因此您不必在 requirements.txt 中安装它。

只需在代码中写入：

import urllib

或

from urllib.request import urlopen
