AI-generated summary

Today, the person continues learning about Flask and how to pass parameters in routes. They write two simple pages using parameter passing and templates to display different content. The code uses Flask to create a web application and defines a route that accepts a parameter called "days". Depending on the value of "days", the code generates different text to display on the page. The code also reads an HTML template file, replaces placeholders with the parameter value and generated text, and returns the modified page. The application runs on host '0.0.0.0' and port 81.

Record#

Today, continue learning about Flask.
Use <> to pass parameters in the route, @app.route('/<pageNumber>'), and accept the parameter with def index(pageNumber).
Today's exercise is to write two simple pages, use parameter passing and templates to display different content.

CODE#

from flask import Flask

app = Flask(__name__)


@app.route('/<days>')
def index(days):
    if days == '78':
        text = "This is the diary for day 78."
    elif days == '79':
        text = "This is the diary for day 79."
    f = open("template/blog.html", "r")
    page = f.read()
    f.close()
    page = page.replace("{days}", days)
    page = page.replace("{text}", text)
    return page


app.run(host='0.0.0.0', port=81)
