python-flask框架&mock接口开发

1、开发一个get接口

import flask
import json
"""
flask轻量级的web开发框架
"""

# 初始化一个服务
server = flask.Flask(__name__)


@server.route(‘/api/payment‘)  # 装饰器：一个接口
def payment():
    data = {"code":301,"msg":"支付处理中","amount":30000}
    return json.dumps(data,ensure_ascii=False)

# http://localhost:9999/api/payment
# http://127.0.0.1:9999/api/payment
server.run(port=9999,debug=True)

结果：

2、post接口

import flask
import json
"""
flask轻量级的web开发框架
"""

# 初始化一个服务
server = flask.Flask(__name__)


@server.route(‘/api/payment‘)  # 装饰器：一个get接口
def payment():
    data = {"code":301,"msg":"支付处理中","amount":30000}
    return json.dumps(data,ensure_ascii=False)


@server.route(‘/api/login‘,methods=[‘post‘])  # 装饰器：一个post接口
def login():
    data = {"code":0,"msg":"登录成功"}
    return json.dumps(data,ensure_ascii=False)

# http://localhost:9999/api/payment
# http://127.0.0.1:9999/api/payment
server.run(port=9999,debug=True)

结果：

3、启动服务，非本地也可以访问

1 # 启动后，别人可以访问
2 # http://ip:9999/api/payment
3 server.run(host=‘0.0.0.0‘,port=9999,debug=True)

运行后，手机访问（同一个局域网）：

4、实例

import flask
import json,pymysql
"""

"""

# 初始化一个服务
server = flask.Flask(__name__)


def op_mysql(sql):
    connect = pymysql.connect(host=‘xxx‘,
                              port=3306,
                              db=‘xxx‘,
                              password=‘xxx‘,
                              charset=‘utf8‘,
                              autocommit=True,
                              user=‘jxz‘
                              )
    cursor = connect.cursor(pymysql.cursors.DictCursor)
    try:
        cursor.execute(sql)
    except Exception as e:
        result = {‘error‘:‘sql错误‘}
    else:
        result = cursor.fetchall()
    finally:
        cursor.close()
        connect.close()
    return result


@server.route(‘/api/payment‘)  # 装饰器：一个get接口
def payment():
    status = flask.request.values.get(‘status‘)
    if status == ‘success‘:
        data = {"code": 0, "msg": "支付成功", "amount": 30000}
    elif status == ‘process‘:
        data = {"code":305,"msg":"支付处理中"}
    elif status == ‘fail‘:
        data = {"code": -1, "msg": "支付失败"}
    else:
        data = {"code": 400, "msg": "支付状态错误"}
    return json.dumps(data,ensure_ascii=False)


@server.route(‘/api/login‘,methods=[‘post‘])  # 装饰器：一个post接口
def login():
    data = {"code":0,"msg":"登录成功"}
    return json.dumps(data,ensure_ascii=False)


@server.route(‘/api/account/data‘)
def account_data():
    #传入参数
    account_name = flask.request.values.get(‘account‘)
    # 获取json格式的参考
    # args = flask.request.json.get(‘xxx‘)
    if account_name:
        result = op_mysql(‘select * from gtm_account where account="%s";‘% account_name)
    else:
        result = op_mysql(‘select * from gtm_account;‘)
    data = {"code":0,"msg":"success","data":result}
    return data

# # 启动服务：启动后只能本地访问
# # http://localhost:9999/api/payment
# # http://127.0.0.1:9999/api/payment
# server.run(port=9999,debug=True)


# 启动服务：启动后别人可以访问
# http://ip:9999/api/payment
# debug=True表示调试模式，改了之后立即生效，不需要重新启动服务
server.run(host=‘0.0.0.0‘,port=9999,debug=True)

结果1：
