我知道在这个GAE / Flask问题上已经有大量的已回答的SO问题，但是没有人解释我正在观察的内容。当我的前端通过https点击Flask应用程序时，它会继续重定向到http，由于HTTP/HTTPS混合内容规则而失败。
这是Chrome开发工具的输出：
Mixed Content: The page at 'https://storage.googleapis.com/staging-fubar/index.html#/?_k=flnjq1' was loaded over HTTPS, but requested an insecure resource 'http://staging-goomba-dot-bingbong.appspot.com/autocomplete/thingy/5'. This request has been blocked; the content must be served over HTTPS.
这是我执行复制->在开发工具中复制为cURL并在终端中执行失败的请求时的输出：

这是到达的路线/终点：
@app.route('/autocomplete/<string:term>',
defaults={"search_type": 'target', "type_str": None, "limit_count": 10},
strict_slashes=False)
@app.route('/autocomplete/<string:term>/<int:limit_count>',
defaults={"search_type": 'target', "type_str": None},
strict_slashes=False)
@app.route('/autocomplete/<string:search_type>/<string:term>',
defaults={"type_str": None, "limit_count": 10},
strict_slashes=False)
@app.route('/autocomplete/<string:search_type>/<string:term>/<int:limit_count>',
defaults={"type_str": None},
strict_slashes=False)
@login_required
def autocomplete(search_type, term, type_str, limit_count):
...
我检查了路由的功能是否没有print anything。在localhost上运行很好，可能是因为SSL没有起作用。
到目前为止，我一直无济于事：
http的{{1}}部分中删除openapi.yaml 对于引起此问题的原因或如何缩小范围的建议将不胜感激！
