示例一：
实现动态路由，代码如下

# coding:utf-8
from flask import Flask
from flask import jsonify
# 创建对象
app = Flask(__name__)users_list = {"1001":["123","张三",19],"1002":["234","李四",22],"1003":["345","王二小",8]}
# 编写路由，构建url与函数的映射关系（将函数与url绑定）
@app.route("/users",methods=["GET"])
def users():return jsonify({"code":10000,"message":"success","data":users_list})# 动态路由，语法：<类型:变量名>
@app.route("/users/<string:account>",methods=["GET"])
def get_user(account):if account in users_list:info = users_list[account]return jsonify({"code":10000,"message":"success","data":{"name":info[1],"age":info[-1]}})else:return jsonify({"code":10001,"message":"success","data":"账户不存在"})if __name__ == '__main__':# 解决jsonify中文乱码问题app.config['JSON_AS_ASCII'] = False# 以调试模式启动,host=0.0.0.0 ,则可以使用127.0.0.1、localhost以及本机ip来访问app.run(host="0.0.0.0",port=8899,debug=True)

查看users接口效果

查看不存在的账户信息

查看单个账户信息

示例二：

实现get请求传参
代码如下

# coding:utf-8
from flask import Flask
from flask import jsonify
from flask import request
# 创建对象
app = Flask(__name__)users_list = {"1001":["123","张三",19],"1002":["234","李四",22],"1003":["345","王二小",8]}
# 编写路由，构建url与函数的映射关系（将函数与url绑定）
@app.route("/users",methods=["GET"])
def users():return jsonify({"code":10000,"message":"success","data":users_list})@app.route("/users/account",methods=["GET"])
def get_user():# 获取请求中的参数account的值account = request.args.get("account")if account:if account in users_list:info = users_list[account]return jsonify({"code":10000,"message":"success","data":{"name":info[1],"age":info[-1]}})else:return jsonify({"code":10001,"message":"success","data":"账户不存在"})else:return jsonify({"code":10001,"message":"success","data":"账户为空"})if __name__ == '__main__':# 解决jsonify中文乱码问题app.config['JSON_AS_ASCII'] = False# 以调试模式启动,host=0.0.0.0 ,则可以使用127.0.0.1、localhost以及本机ip来访问app.run(host="0.0.0.0",port=8899,debug=True)

参数为空，效果如下

传递正常参数，效果如下
