import pymysql
from flask import Flask,request# 这里是mysql的基本连接信息
conn = pymysql.connect(host="192.168.1.116",user="root",password="123",database="nydb1",charset="utf8"
)cursor = conn.cursor()app = Flask(__name__)@app.route("/")
def hello_world():sel = "select * from school"result = cursor.execute(sql)# 得到查询后的真正的结果r = cursor.fetchall()print(r)return str(r)@app.route("/mypost",methods=["post"])
def my_post():return "post request"@app.route("/mypost1",methods=["post"])
def my_post1():# 表单数据类型username =request.form["username"]sex = request.form["sex"]print(username)print(sex)return "post request" + username + "::" + sex@app.route("/mypost1",methods=["post"])
def my_post2():# json数据类型request_data =request.get_json()sex = request.form["sex"]print(request_data)print(request_data["user"])return "post request" + str(request_data)@app.route("/mypost",methods=["post"])
def my_post():return "post request"@app.route("/mypost1",methods=["post"])
def my_post1():# 表单数据类型username =request.form["username"]sex = request.form["sex"]print(username)print(sex)return "post request" + username + "::" + sex@app.route("/mypost1",methods=["post"])
def my_post2():# json数据类型request_data =request.get_json()sex = request.form["sex"]print(request_data)print(request_data["user"])return "post request" + str(request_data)if __name__ == "__main__":app.run()

• 执行代码后打开链接：http://127.0.0.1:5000
• 将127.0.0.1:5000输入到postman里面执行：
• 另外在代码里看到/hello,也可以输入执行查看结果：
