Question

我正在尝试使用Kivy AsyncImage，如下所示：

import kivy
from kivy.loader import Loader
from kivy.app import App
from kivy.uix.image import AsyncImage


class MyApp(App):

    def build(self):
        return AsyncImage(source="https://colruyt.collectandgo.be/cogo/step/JPG/JPG/500x500/std.lang.all/64/86/asset-366486.jpg")


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

但我收到错误：

[ERROR  ] [Loader      ] Failed to load image <https://colruyt.collectandgo.be/cogo/step/JPG/JPG/500x500/std.lang.all/64/86/asset-366486.jpg>
Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/kivy/loader.py", line 342, in _load_urllib
    data = self._load_local(_out_filename, kwargs)
  File "/usr/local/lib/python2.7/dist-packages/kivy/loader.py", line 277, in _load_local
    return ImageLoader.load(filename, keep_data=True, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/kivy/core/image/__init__.py", line 432, in load
    raise Exception('Unknown <%s> type, no loader found.' % ext)
Exception: Unknown <html> type, no loader found.
an integer is required

如果我在Mac或Raspberry Pi上运行此操作，也会发生同样的情况。我究竟做错了什么？

编辑：

这似乎是一个http头问题。该url返回一个html错误页面，因为http标头不正确：

<html><head><title>Request Rejected</title></head><body>The requested URL was rejected. Please consult with your administrator.<br><br>Your support ID is: 2461894905373175944</body></html>

我无法弄清楚如何在Kivy中为AsyncImage设置自定义标头。有什么建议吗？

AsyncImage无法获取图像
