1、安装flask框架。
pip install flask -i https://pypi.tuna.tsinghua.edu.cn/simple/
2、web 示例。
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_flask():
return 'Hello, World!'
if __name__ == '__main__':
app.run(host='0.0.0.0', port=80, debug=False)
3、访问：http://192.168.2.16/
更新【2022-12-07】：
1、get请求、post请求
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/')
def hello_flask():
return 'Hello, World!'
@app.route('/login', methods=['GET'])
def hello_world():
# get请求及参数获取方式
# 获取参数对应值
name = request.args.get("name")
return "welcome" + " " + name
@app.route('/check', methods=['POST'])
def hello_check():
# post请求及参数获取方式
# 获取参数对应值
name = request.form.get("name")
return "welcome" + " " + name
if __name__ == '__main__':
app.run(host='0.0.0.0', port=80, debug=False)
通过postman进行get测试
通过postman进行post测试
2、json递交、返回json。
from flask import Flask
from flask import request
from flask import jsonify
app = Flask(__name__)
@app.route('/')
def hello_flask():
return 'Hello, World!'
@app.route('/login', methods=['GET'])
def hello_world():
# get请求及参数获取方式
# 获取参数对应值
name = request.args.get("name")
return "welcome" + " " + name
@app.route('/check', methods=['POST'])
def hello_check():
# post请求及参数获取方式
# 获取参数对应值
name = request.form.get("name")
return "welcome" + " " + name
@app.route('/sync', methods=['POST'])
def hello_sync():
# post请求及参数获取方式
# 获取参数对应值
data = request.get_json()
name = data['name']
code = data['code']
# return "welcome" + " " + name + " " + code
return jsonify({"login": name, "token": 9})
if __name__ == '__main__':
app.run(host='0.0.0.0', port=80, debug=False)
