Ionic 4 Leaflet Map不适用于部署，但适用于离子服务--devapp

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Ionic 4 Leaflet Map不适用于部署，但适用于离子服务--devapp相关的知识，希望对你有一定的参考价值。
我有一个带有传单/ openstreetmap的应用程序，它可以正常工作。在浏览器，android和ios设备上运行ionic serve --devapp时，地图可以完美运行。我已经通过使用电容器的android studio通过android studio达到了在android设备上进行部署测试的阶段，并且传单图块没有显示，没有错误可以找到，我确定它必须在某个地方。尽管传单/ openstreetmap磁贴不起作用，但标记和多边形以及我所有应用程序的功能均正常工作，只是没有磁贴。
我真的不知道问题是什么，如果对我的依赖项或插件的设置有任何建议，或者在config.xml或index.html中缺少建议，将不胜感激！

答案
我找到了解决方案。在华为手机上并尝试显示外部来源的地图图块时，它需要在HTTP URL上使用https URL，而与三星不同，华为设备将拒绝该来源。我只是将http更改为https，并且无需任何其他代码更改即可访问tile源。
