GCP（应用引擎）上的问题 运行 python Flask Restplus API
problems running python Flask Restplus API on GCP (app engine)
我正在开发一个必须在 GCP 上运行的 API Rest 应用程序。该应用程序 运行 在本地运行良好，但当我将其部署到 GPC 时却无法运行。
我在 Python 3.7 中编写了 web 服务，使用 Flask、SQLAlchemy、Flask-SQLAlchemy、Flask-Restplus（为了拥有 Swagger）。
我在部署时没有任何错误，但是当我想访问文档时（招摇）我有 "No Api definition provided" 消息，当我尝试 运行 GET 方法时我'有一个（严重的）工人超时错误。
如果你能给我任何帮助，我将不胜感激。
祝你有美好的一天！！

多亏了你提供的错误信息，事情现在更清楚了。所以这条消息
Mixed Content: The page at '*****' was loaded over HTTPS, but
requested an insecure resource 'http://****/swagger.json'. This
content should also be served over HTTPS.
表示您的 App Engine 正在尝试通过 HTTPS 提供内容。但是，您的 Flask Restplus 正在发送 HTTP 请求。这里它试图获取“http://****/swagger.json”
使用 HTTP 请求。由于这种不匹配，呼叫被阻止，您收到“未提供 API 定义”。
为了解决这个问题，我注意到您正在使用“werkzeug”中间件。
将此代码添加到您的 Flask 初始化中：
from werkzeug.middleware.proxy_fix import ProxyFix
app = Flask(__name__)
app.wsgi_app = ProxyFix(app.wsgi_app)
您可以阅读原始问题 here。
希望对您有所帮助。
我正在开发一个必须在 GCP 上运行的 API Rest 应用程序。该应用程序 运行 在本地运行良好，但当我将其部署到 GPC 时却无法运行。
我在 Python 3.7 中编写了 web 服务，使用 Flask、SQLAlchemy、Flask-SQLAlchemy、Flask-Restplus（为了拥有 Swagger）。
我在部署时没有任何错误，但是当我想访问文档时（招摇）我有 "No Api definition provided" 消息，当我尝试 运行 GET 方法时我'有一个（严重的）工人超时错误。
如果你能给我任何帮助，我将不胜感激。
祝你有美好的一天！！

多亏了你提供的错误信息，事情现在更清楚了。所以这条消息
Mixed Content: The page at '*****' was loaded over HTTPS, but requested an insecure resource 'http://****/swagger.json'. This content should also be served over HTTPS.
表示您的 App Engine 正在尝试通过 HTTPS 提供内容。但是，您的 Flask Restplus 正在发送 HTTP 请求。这里它试图获取“http://****/swagger.json”
使用 HTTP 请求。由于这种不匹配，呼叫被阻止，您收到“未提供 API 定义”。
为了解决这个问题，我注意到您正在使用“werkzeug”中间件。
将此代码添加到您的 Flask 初始化中：
from werkzeug.middleware.proxy_fix import ProxyFix
app = Flask(__name__)
app.wsgi_app = ProxyFix(app.wsgi_app)
您可以阅读原始问题 here。
希望对您有所帮助。
