导入对应模块
from flask import Flask
from flask import render_template
from flask import request
from flask import url_for, redirect
from mysql import DbMysql
app = Flask(__name__)
模版渲染&数据传递
# 直接输出页面
@app.route('/')
def index():
data_name = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
data_list = [150, 230, 224, 218, 135, 147, 260]
return render_template('index.html', data_name=data_name, data_list=data_list)
对接MySql数据库
@app.route('/echarts')
def get_echarts():
db = DbMysql()
items = db.get_items()
return render_template('echarts.html', items=items)get路径参数
# get路径参数
@app.route('/api')
def get_api():
# api?user=Flask&time=2021-09-15&page=7&pagesize=100
print(request.path)
print(request.full_path)
# return request.args.get('user') # 获取某个指定的参数
return request.args.__str__()
动态url参数
@app.route('/<lang_code>/index')
def get_lang(lang_code):
return lang_code跳转页面
# 跳转页面;
@app.route('/test')
def test():
print('this is test1')
return redirect(url_for('get_echarts'))
# with app.test_request_context():
# print(url_for('index'))
# print(url_for('get_test'))
# print(url_for('get_echarts'))
# print(url_for('user', name='lockdatav'))
# print(url_for('page', num=1, q='hadoop mapreduce 10%3'))
# print(url_for('static', filename='uploads/01.jpg'))
if __name__ == '__main__':
app.run(host='localhost', port=8800, debug=True)
lockdatav Done!
