Flask Route

Flask是python網站開發微框架。

• 在pycharm中安裝flask

File->Setting-選到自己的Project->Project Interpreter-> ┼ (右邊加號)>搜尋flask->install package

• Flask中的路由

新增一檔案名為app.py，import Flask

#making available the code you need to build web apps with flask

from flask import Flask, render_template
# create an instance of the Flask class for our web app
app = Flask(__name__)


# when the user navigates to localhost:5000, 

# the home function will run and it will return its output on the webpage.
@app.route("/")def hello():
    # return "<h3>Hello World! 123</h3>"

    # 利用render_template()導到html檔案，

    # 要注意的是：1.需import render_template 2.該html檔要放在根目錄的Templates目錄之下    return render_template("home.html")

# If the input to the route method was something else, let’s say ‘/abc/’, 
# the function output would be shown when the user visited localhost:5000/abc/
@app.route("/abc")def hello2():
    return 'Hello World! 45678'

# 執行該application，當debug=True，開發環境中則不必重啟server，重新整理網頁即可

app.run(debug=True) 

點選RUN執行，即可看到結果。
