使用 Flask 框架编写的一个简单的 Python POST和GET接口

安装 Flask

pip install Flask

 

使用python实现POST接口

from flask import Flask, request, jsonify

app = Flask(__name__)


@app.route('/test', methods=['POST'])
def submit():
    # 获取 JSON 请求体
    data = request.get_json()

    # 从请求体中提取参数
    name = data.get('name')
    uuid = data.get('uuid')

    # 打印参数
    print(f"Name: {name}, UUID: {uuid}")

    # 检查参数是否存在
    if not name or not uuid:
        response = {
            'status': 'error',
            'message': 'Missing name or uuid',
            'data': None
        }
        return jsonify(response), 400

    # 响应内容
    response = {
        'status': 'success',
        'message': 'Data received',
        'data': {
            'name': name,
            'uuid': uuid
        }
    }
    return jsonify(response), 200


if __name__ == '__main__':
    app.run(host='0.0.0.0', port=6101, threaded=True)  # 在局域网内可访问

 

使用python实现GET接口

from flask import Flask, request, jsonify

app = Flask(__name__)


@app.route('/test2', methods=['GET'])
def get_info():
    # 从请求参数中获取 name 和 uuid
    name = request.args.get('name')
    uuid = request.args.get('uuid')

    # 检查参数是否存在
    if not name or not uuid:
        response = {
            'status': 'error',
            'message': 'Missing name or uuid',
            'data': None
        }
        return jsonify(response), 400

    # 返回规范的响应
    response = {
        'status': 'success',
        'message': 'Data received',
        'data': {
            'name': name,
            'uuid': uuid
        }
    }
    return jsonify(response), 200

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=6101, threaded=True)  # 在局域网内可访问

 

 

扩展：使用requests调用get和post请求

pip安装：pip install requests

import requests

class HTTP:
    # 发送GET请求
    def get(self, url, return_json=True):
        response = requests.get(url)
        if response.status_code == 200:
            if return_json:
                return response.json()
            else:
                return response.text
        else:
            print(f"Error: {response.status_code}")
            return None
    
    # 发送POST请求
    def post(self, url, data, headers={}, return_json=True):
        response = requests.post(url, data=data, headers=headers)
        if response.status_code == 200:
            if return_json:
                return response.json()
            else:
                return response.text
        else:
            print(f"Error: {response.status_code}")
            return None
