flask 开发Restful API（post和get方式实例）

命令行安装flask

pip install flask 

新建脚本api.py

from flask import Flask
from flask import request
import json

app = Flask(__name__)
 
@app.route('/') #默认get
def index():
  return 's'
  
@app.route('/getData') # url=127.0.0.1:8999/getData
def getData():
  name=request.values.get('name')
  age=request.values.get('age')
  print(name)
  print(age)
  if name=='test':
   return 's'
  else:
   return 'again'
  
@app.route('/postData',methods=['get','post']) #可以写多个方法
def postData():
  if request.method=='POST':  #大写
     name=request.form['name']
     if name=='test':
      return 's'
     else:
      return 'again'
  else:
    return 'gggg'
	  
@app.route('/postJson',methods=['get','post'])
def postJson():
  if request.method== 'POST':  #大写
      data=request.get_data()
      json_data=json.loads(data.decode('utf-8'))
      print(json_data)
      name=json_data.get("name")
      age=json_data.get("age")
      print("name=%s,age=%s" %(name,age))
      if name=='test':
        return 's'
      else:
       return 'again'
  else:
      return 'gggg'  
	   
	  
if __name__ == '__main__':
 app.run(port=8999,debug=True) #host默认0.0.0.0 port默认5000 

Postman调用测试

结果打印
