Python - 如何从同一客户端计算机运行多个烧瓶应用程序

I have one flask application script as given below :

我有一个烧瓶应用程序脚本,如下所示:

from flask import Flask
app = Flask(__name__)

@app.route("/<string:job_id>")
def main(job_id):
    return "Welcome!. This is Flask Test Part 1"

if __name__ == "__main__":
    job_id = 1234
    app.run(host= '0.0.0.0')

I have another flask application script as below :

我有另一个烧瓶应用程序脚本如下:

from flask import Flask
app = Flask(__name__)

@app.route("/<string:ID>")
def main(ID):
    return "Welcome!. This is Flask Test Part 2"

if __name__ == "__main__":
    ID = 5678
    app.run(host= '0.0.0.0')

The only difference between both the scripts is the argument name and its value. Now my question is assume that I am executing the first script. So I will get something like

两个脚本之间的唯一区别是参数名称及其值。现在我的问题是假设我正在执行第一个脚本。所以我会得到类似的东西

* Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)

When I execute http://127.0.0.1:5000/1234 in my browser I am able to see

当我在浏览器中执行http://127.0.0.1:5000/1234时,我能够看到

"Welcome!. This is Flask Test Part 1"

“欢迎!这是Flask Test Part 1”

Now with this server active, I am executing the second script. So again I get

现在这个服务器处于活动状态,我正在执行第二个脚本。所以我再次得到

* Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)

But when I execute http://127.0.0.1:5000/5678 in my browser I am able to see

但是当我在浏览器中执行http://127.0.0.1:5000/5678时,我能够看到

"Welcome!. This is Flask Test Part 1"

“欢迎!这是Flask Test Part 1”

instead of

"Welcome!. This is Flask Test Part 2"

“欢迎!这是Flask Test Part 2”

I don't understand where I am doing mistake. Any inputs or alterations will be helpful

我不明白我在哪里做错了。任何输入或更改都会有所帮助

Flask development server by default listen on port 5000. So when you run a Flask app without port number it will run on 5000.

Flask开发服务器默认侦听端口5000.因此,当您运行没有端口号的Flask应用程序时,它将运行在5000上。

You can run number of Flask app on the same machine but with different port number. Lets say your scripts names are script1.py and script2.py:

您可以在同一台计算机上运行多个Flask应用程序,但使用不同的端口号。让我们说你的脚本名称是script1.py和script2.py:

$ export FLASK_APP=script1.py
$ flask run --host 0.0.0.0 --port 5000

Open up a new terminal

打开一个新的终端

$ export FLASK_APP=script2.py
$ flask run --host 0.0.0.0 --port 5001
