Python 停靠应用程序后无法访问flask终结点

我正在开发一个flask应用程序，它有一个注册的URL列表。我能够在本地运行flask应用程序并访问为其注册的URL

但是当我对应用程序进行dockerize并使用docker compose运行它时，我无法访问应用程序的URL

在本地运行应用程序时，如果我访问应用程序的

app.url\u map

，我就能够看到该应用程序的所有注册url的列表。（我创建了一个端点-

/url

，当点击它时返回

url\u-map

列表）

但在docker中运行应用程序后，当我尝试点击同一个端点-

/url

时，除了基本上是自己的

/url

端点之外，我看不到任何列表

我哪里做错了

以下是wsgi.py文件：

import os
from flask import Flask, jsonify
from app.workload.views import register_workload_urls

def load_urls(app):
    app_mode = os.getenv("APP_MODE")
    if app_mode == "WORKLOAD":
        register_workload_urls(app)

application = Flask(__name__)

@application.route('/urls')
def urls():
    return jsonify({"APP": str(os.getenv("APP_MODE")), "URLs registered": f"{str(application.url_map)}"})

if __name__ == "__main__":
    load_urls(application)
    application.run()

视图。py:

def register_workload_urls(application):
    @application.route('/api/workload/health/check/')
    def w_check():
        return jsonify({'status': f"Workload service is {app.config_pub.status}."})

    @application.route('/api/workload/health/up/')
    def w_up():
        app.config_pub.status = "UP"
        app.config_pub.dispatch("UP")
        return jsonify({'status': f"Workload service is {app.config_pub.status}."})

    @application.route('/api/workload/health/down/')
    def w_down():
        app.config_pub.status = "DOWN"

在docker中运行时

/URL的输出：

}

{
“应用程序”：“工作量”，
已注册的URL:“映射（[URL>，\n静态>]）”
}
将代码放在
wsgi.py
文件中似乎有问题。从
wsgi.py
文件中删除了应用程序创建代码，并将其粘贴到
app
文件夹中的
\uuuu init\uuuuu.py
文件中，并从此处导入该函数

现在一切正常。
如果浏览到/URL，输出是什么。您能够访问flask Web服务器吗？您在日志中看到了什么吗？
/url
的输出是已注册的URL列表。我能联系到烧瓶服务器。在日志中，我看到的只是当我点击除
/url
之外的任何端点时出现的404错误。更新了带有
/url
输出的问题。好的，为了测试一些东西，您可以尝试将视图中的函数直接放在init.py中，并将其移除，而不是寄存器\u工作负载\u URL
