一、delete 请求

1.1 代码

from flask import Flask, request

app = Flask(__name__)


@app.route('/')
def hello_world():  # put application's code here
    return 'Hello World!'


# delete获取请求参数
@app.route('/user', methods=['DELETE'])
def delete_user_info():
    user_list = [{"user_name": "zhangsan"}, {"user_name": "neil"}]
    # user_name = request.args.get('user_name')
    user_name = request.values.get("user_name")
    # 将数据再次打包为 JSON 并传回
    for user in user_list:
        if user.get("user_name") == user_name:
            user_list.remove(user)

    return user_list
    

if __name__ == '__main__':
    app.run(host="0.0.0.0", debug=True)

1.2 分析

限定请求只响应路径为 /user时的DELETE请求
```
@app.route('/user', methods=['DELETE'])
def method():
  ...
```
- 使用’/user’限制请求响应的路径
- 使用methods 进行请求方式限定

获取参数的方式

# 获取DELETE后参数的方法
request.args.get('user_name')
request.values.get('user_name')

1.3 验证

postman 请求参数
postman header 如下（使用默认）
请求结果

二、put请求

2.1 代码

from flask import Flask, request

app = Flask(__name__)


@app.route('/')
def hello_world():  # put application's code here
    return 'Hello World!'


# PUT 获取请求参数
@app.route('/user', methods=['PUT'])
def put_user_info():
    user_list = [{"user_name": "zhangsan", "age": 18}, {"user_name": "neil", "age": 20}]

    # postman 使用请求头application/json
    # user_info = request.get_json()

    # postman 使用请求头text/plain
    # user_info = request.get_data()

    # postman 使用application/x-www-form-urlencoded请求
    # user_info = request.values

    # postman 使用multipart/form-data请求
    user_info = request.form

    for user in user_list:
        if user.get("user_name") == user_info.get("user_name"):
            user.update(user_info)

    return user_list


if __name__ == '__main__':
    app.run(host="0.0.0.0", debug=True)
