python_flask框架学习笔记二[不同请求方法]

flask不同请求方法的应用：

1、GET

@app.route('/meter/test', methods=['GET'])
def index01():
    name = request.args.get("name")
    content = {
        'resultCode': 0,
        'message': "操作成功",
        'total': 290
    }
    if name == 'vivage':
        return jsonify(**content)
    else:
        return u'传参错误'

 

 2、POST

@app.route('/meter/testpost', methods=['POST'])
def index02():
    username = request.json.get("username")
    password = request.json.get("password")
    content = {
        'resultCode': 0,
        'message': "登录成功"
    }
    if username == 'test' and password == '0':
        return jsonify(**content)
    else:
        return u'账号/密码不正确'

 

 

3、DELETE

@app.route('/meter/testdelete/', methods=['DELETE'])
def index03():
    id = request.json.get("id")
    content1 = {
        'resultCode': 0,
        'message': "删除成功"
    }
    content2 = {
        "resultCode": 10002,
        "message": "该部门不存在"
    }
    if id == 123:
        return jsonify(**content1)
    else:
        return jsonify(**content2)


@app.route('/meter/testdelete/<int:id>', methods=['DELETE'])
def index04(id):
    content1 = {
        'resultCode': 0,
        'message': "删除成功"
    }
    content2 = {
        "resultCode": 10002,
        "message": "该部门不存在"
    }
    if id == 123:
        return jsonify(**content1)
    else:
        return jsonify(**content2)

 

 

4、PUT

@app.route('/meter/testput/', methods=['PUT'])
def index05():
    name = request.json.get("name")
    age = request.json.get("age")
    if name == 'vivage':
        age = age -1
        return jsonify(name=name, age=age)
    else:
        return jsonify(msg="用户不存在，无法修改")
