如何在Google合作Python笔记本中使用Flask？

Question

我正在尝试在Google Colab Python笔记本中使用Flask构建网站。但是，运行适用于常规Python的常规Flask代码无法在Google Colab上运行。我需要可以解决的代码.. :)

Answer 1

!pip install flask-ngrok


from flask import Flask
from flask import request
from flask_ngrok import run_with_ngrok

app = Flask(__name__)
run_with_ngrok(app)  # Start ngrok when app is run

# for / root, return Hello Word
@app.route("/")
def root():
    url = request.method
    return f"Hello World! {url}"

app.run()

Answer 2

服务器代码：

import socket
print(socket.gethostbyname(socket.getfqdn(socket.gethostname())))

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

import threading
threading.Thread(target=app.run, kwargs={'host':'0.0.0.0','port':80}).start() 

客户代码：

import requests
r = requests.get("http://172.28.0.2/")
print(r.status_code)
print(r.encoding)
print(r.apparent_encoding)
print(r.text)

要重启Flask，您可以单击菜单：runtime-> restart runtime
