Today's lesson focused on the method for receiving variables in a request, specifically using the "get" method. The "get" method involves passing variables through the URL, and in the code, the "request.args" function is used to access all the variables and their values passed through the URL. In the route definition, the method needs to be specified as "GET". There are two differences compared to the "post" method: the route definition includes both "post" and "get" methods, and the variables in the code are copied into two different variables, "form.request" and "request.args". The exercise involved passing variables through the URL to display a webpage in two different languages, English and Chinese.

Record#

Today I learned the method for receiving variables in the request: get.
The get method is passed through URL parameters, and in the code, request.args is used to access all the variables and their values passed through the URL.
The receiving method still needs to be defined in the route definition: methods=['GET']
There are two differences compared to post:
1. In the route definition, one is for receiving post and the other is for receiving get.
2. In the code, one variable is assigned to form.request and the other is assigned to request.args.
Today's exercise is to pass variables through the URL and display a page in two languages.

CODE#

from flask import Flask, request
app = Flask(__name__)


@app.route('/', methods=["GET"])
def index():
    data = request.args
    if data["lang"].lower() == "en":
        return "Hello English"
    elif data["lang"].lower() == "cn":
        return "你好 中国话"


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