Flask写接口一（路由，json , session模拟登录）

from flask import Flask, request, jsonify, session
from werkzeug.utils import redirect

app = Flask(__name__)
# 使用session必须给应用加密
app.secret_key = "asdasdasdasdasdsaa"

@app.route("/my/<float:number>")
def my_number(number):
    return "我的数字 %s" % (number + number)


@app.route("/bilibili")

    return redirect("https://www.bilibili.com/")


@app.route("/test/my/first", methods=["POST"])

    try:
        my_json = request.get_json()
        print(my_json)
        get_name = my_json.get("name")
        get_age = my_json.get("age")
        if not all([get_name, get_age]):
            return jsonify(msg="缺少参数")

        get_age += 10

        return jsonify(name=get_name, age=get_age)
    except Exception as e:
        print(e)
        return jsonify(msg="出错了哦，请查看是否正确访问")

        session["username"] = username
        return jsonify(msg="登录成功")
