我们有一个正在运行的代理，它为互联网提供 HTTPS 页面。因此，它将请求重定向到我们的 DMZ，其中页面作为 HTTP 页面提供。
我们将 WireCloud 设置为在子域中运行：wirecloud.example.com。Horizon 在 Horizon.example.com 上运行。
在 Horizon 中，回调 URL 设置为：http : //wirecloud.example.com/complete/fiware/ 并在 Wirecloud 的 settings.py 中FIWARE_IDM_SERVER = 'http://horizon.example.com'设置。
现在，当wirecloud.example.com/login被调用时，它被我们的代理重定向到 https ，然后被wireclound重定向到horizon ，然后被我们的代理重定向到https://horizon.example.com/oauth2/authorize/?state=STATE_KEY&redirect_uri=http://wirecloud.example.com/complete/fiware/&response_type=code&client_id=CLIENT_ID. 如果用户未登录并且现在这样做了，则 redirect_uri 将转换为：http%253A%252F%252Fwirecloud.example.com%252Fcomplete%252Ffiware%252F导致此错误的原因：{"state": "STATE_KEY", "error": "invalid_redirect_uri"} (HTTP 400)。如果用户已经登录并尝试授权应用程序 (WireCloud)，则会引发 405 错误：

那么我们需要如何配置 WireCloud 和/或 Horizon 和/或我们的代理才能使其正常工作呢？
