1.最近公司运维需求，学习python flask 满足环境治理系统的开发;入门如下;
环境类型:
Python 2.7.5 获取地址:https://www.python.org/downloads/
Flask 1.0.2
pip 安装使用模快如下；
flask==1.0.2
request==1.0.2
Jinja2==2.10
Flask-Cors==3.0.6
MySQL-python==1.2.3
Bootstrap 4.0 获取地址:https://v4.bootcss.com/docs/4.0/getting-started/download/
开发IDE 工具
pycharm Professional 获取地址:https://www.jetbrains.com/pycharm/
2.启动flask 实例代码如下;
代码功能如下:
(1).访问允许跨域
(2).静态资源目录定义
(3).模板渲染;
(4).路由解析
(5).用户表单提交和校验;
(6).数据层处理;
# -*- coding: utf-8 -*-
import sys
import time
from flask import Flask, request, render_template, Response
from flask_cors import CORS
from models import User
###需要安装 pip install -U flask-cors 模块# 解决跨域模块###
reload(sys)
sys.setdefaultencoding('utf-8')
##############定义静态文件存放路径########################
# app
app = Flask(import_name=__name__, static_folder='./static', static_url_path='/static',
template_folder='./templates')
CORS(app, resources=r'/*')
# r'/*' 是通配符，让本服务器所有的URL 都允许跨域请求
#########
@app.route('/', methods=['GET', 'POST']) ####默认首页###########
def index():
class Person(object):
Email = '[email protected]'
gender = 'male'
time = time.asctime(time.localtime(time.time()))
dell = Person()
context = {
'username': 'breaklinux',
'password': '123456',
'age': '25',
'hobby': 'python',
'person': dell,
'wwwurl': {
'baidu': 'www.baidu.com',
'google': 'www.google.com'
}
}
return render_template('html/index.html', **context) #
##################命名规范flask 路由解析##############
@app.route('/naming', methods=['GET', 'POST'])
def naming():
Query_tow = User()
Naming_List_name = Query_tow.Query_naming("环境治理类")
Naming_List_name_nuber2 = Query_tow.Query_naming("发布规范类")
return render_template('html/naming.html', Naming_List_name=Naming_List_name,
Naming_List_name_nuber2=Naming_List_name_nuber2)
@app.route('/create_naming', methods=['GET', 'POST'])
def create_naming():
return render_template('html/create_naming.html')
@app.route("/sigin_naming", methods=['GET', 'POST'])
def sigin_naming():
##########get 方法######request.args
##########post 方法#####rquest.from######
################获取用户表单输入数据###########
naming_name = request.args['naming_name']
naming_url = request.args['naming_url']
naming_type = request.args['naming_type']
create_founder = request.args['naming_create_founder']
##################获取当前提交时间###################
create_time = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
####################判断表单用户输入是否为空,为空跳转当前页面############
if ("" == naming_name) or ("" == naming_url) or ("" == create_founder):
return render_template('html/create_naming.html')
else:
#############实例化 models 文件 User 类和携带用户提交表单参数################
user = User()
user.save(naming_type,naming_name, naming_url, create_time, create_founder) ##############调用class 类中save方法################
return Response(u'新增成功' + "\n" "日期" + "\n" + create_time)
if __name__ == '__main__':
app.run(
host="0.0.0.0",
port=80,
debug=True
)
2.views 视图展示层;

3.数据层;
# -*- coding: utf-8 -*-
import MySQLdb
def get_conn():
host = "192.168.xx.xx"
port = 3306
db = "Scier"
user = "root"
password = "123456"
conn = MySQLdb.connect(host, user, password, db, port, charset='utf8')
return conn
class User(object):
def save(self,type, name, url, create_time, create_founder):
self.type = type
self.name = name
self.url = url
self.create_time = create_time
self.create_founder = create_founder
conn = get_conn()
cursor = conn.cursor()
sql = ("insert into naming (type,name,url,create_time,create_founder) VALUES (%s,%s,%s,%s,%s)")
data = (self.type, self.name, self.url, self.create_time, self.create_founder)
try:
cursor.execute(sql, data)
conn.commit()
cursor.close()
conn.close()
except:
cursor.close()
conn.close()
return "Error: unable to table namin"
def Query_naming(self,type1):

cursor = conn.cursor()
self.type1 = type1
# SQL 查询语句命名规范名称和url地址字段#######
sql = "SELECT NAME,url FROM naming WHERE TYPE='%s'" % self.type1
try:
# 执行SQL语句
cursor.execute(sql)
# 获取所有记录列表
results = cursor.fetchall()
cursor.close()
conn.close()
return results
except:
cursor.close()
conn.close()
return "Error: unable to fecth data"
4.视图页面效果；
