带有https的Kivy UrlRequest

Question

我正在尝试获取Python 3.7 Kivy代码以使用UrlRequest检索https网络数据。代码可以很好地与http配合使用，但是将URL更改为任何https时却没有任何数据。当我同时使用http或https编译并运行时，两者都运行无误。我需要添加导入以使https工作吗？这是测试代码。谢谢。

from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.gridlayout import GridLayout

from kivy.network.urlrequest import UrlRequest
from functools import partial

class MainApp(App):
    def build(self):
        grid = GridLayout(cols=1)
        button1 = Button(text="Press to say Hello", 
        on_release=self.run_Hello)
        button2 = Button(text="Kivy UrlRequest", 
        on_release=self.run_UrlRequests)
        blank_button = Button(text="Click me!")
        grid.add_widget(button1)
        grid.add_widget(button2)
        grid.add_widget(blank_button)
        return grid

def run_Hello(self, *args):
    print("Hello")


def run_UrlRequests(self, *args):
    for i in range(10):
        self.r = UrlRequest("https://www.google.com", verify=False, 
    on_success=partial(self.update_label, i), 
    on_error=partial(self.error_label, i))

def update_label(self, i, *args):
    print(i)
    print("success")
    print(self.r.result)

def error_label(self, i, *args):
    print("failed")
    print(i)
    print(self.r.result)

MainApp（）。run（）

Answer 1

以下示例说明了如何针对https使用Kivy UrlRequest

示例

main.py

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.network.urlrequest import UrlRequest
from kivy.uix.rst import RstDocument
from kivy.uix.label import Label


class MyWidget(BoxLayout):
    def __init__(self, **kwargs):
        super(MyWidget, self).__init__(**kwargs)
        self.orientation = 'vertical'
        search_url = "https://www.metservice.com/towns-cities/christchurch/christchurch-city"
        self.add_widget(Label(text=search_url, size_hint=(1, 0.1)))
        self.request = UrlRequest(search_url, self.res)

    def res(self, *args):
        self.add_widget(RstDocument(text=self.request.result))


class MyApp(App):
    def build(self):
        return MyWidget()


if __name__ == '__main__':
    MyApp().run()

输出

Answer 2

def run_UrlRequests(self, *args):
    for i in range(10):
    self.r = UrlRequest("https://www.google.com", verify=False, 
    on_success=partial(self.update_label, i), on_error=partial(self.error_label, i)) 

我在UrlRequest之后也添加了verify = False，也添加到了原始代码中。该代码运行并生成html数据的打印语句。尽管这可以解决https问题，但我不知道此明显的SSL问题是否已得到正确解决。
