在Jupyter笔记本中显示Flask应用程序输出 [英] Display flask app output in Jupyter notebook

问题描述

我正在从jupyter笔记本上运行基本的flask脚本.我可以通过Web浏览器访问它，但是与从命令行运行脚本不同，该单元不会输出请求日志.有没有一种方法可以在笔记本中显示日志.

I'm running a basic flask script from a jupyter notebook. I can access it through a web browser but the cell doesn't output the requests log unlike when the script is run from a commandline. Is there a way to display the log in the notebook.

这是脚本

%load_ext ipyext.writeandexecute

%%writeandexecute -i myflask myflask.py
from flask import Flask
app = Flask(__name__)

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

if __name__ == "__main__":
    app.run()

推荐答案

以防其他人遇到相同的问题.我通过从Jupyter打开终端来解决这个问题

Just in case others face the same problem. I've gotten around this by opening a terminal from Jupyter

用%% writefile myflask.py替换writeandexecute魔术

replace the writeandexecute magic with %%writefile myflask.py

并在一个新单元格中

import subprocess as sub

# this opens a windows terminal
sub.call('start /wait python myflask.py', shell=True)
