环境准备

python安装:默认安装；
flask安装

pip install flask

api接口开发

get请求

from flask import Flask, request
import json
app = Flask(__name__)
# get请求
@app.route("/get", methods=["GET"])
def get():
    # 默认返回内容
    return_dict = {'return_code': '200', 'return_info': '处理成功', 'result': False}
    # 判断入参是否为空
    if request.args is None:
        return_dict['return_code'] = '5004'
        return_dict['return_info'] = '请求参数为空'
        return json.dumps(return_dict, ensure_ascii=False)
    # 获取传入的params参数
    get_data = request.args.to_dict()
    name = get_data.get('name')
    age = get_data.get('age')
    # 对参数进行操作
    return_dict['result'] = tt(name, age)
    return json.dumps(return_dict, ensure_ascii=False)
# 功能函数
def tt(name, age):
    result_str = "%s今年%s岁" % (name, age)
    return result_str
if __name__ == "__main__":
    app.run(debug=True)

测试：使用postman调用接口

post请求

from flask import Flask, request
import json
app = Flask(__name__)
# post请求
@app.route("/post", methods=["POST"])
def post():
    # 默认返回内容
    return_dict = {'return_code': '200', 'return_info': '处理成功', 'result': False}
    # 判断入参是否为空
    if request.args is None:
        return_dict['return_code'] = '5004'
        return_dict['return_info'] = '请求参数为空'
        return json.dumps(return_dict, ensure_ascii=False)
    # 获取传入的参数
    data = request.get_data()
    data = json.loads(data)
    name = data.get('name')
    age = data.get('age')
    # 对参数进行操作
    return_dict['result'] = tt(name, age)
    return json.dumps(return_dict, ensure_ascii=False)
# 功能函数
def tt(name, age):
    result_str = "%s今年%s岁" % (name, age)
    return result_str
if __name__ == "__main__":
    app.run(debug=True)
