【软件测试基础知识】如何使用fiddler模拟接口服务器

1、案例描述

案例：我们的APP使用了某天气预报接口，其接口描述如下：

接口名称：根据城市名查询天气

接口地址：http://v.juhe.cn/weather/index

返回格式：json/xml

请求方式：get

请求示例：http://v.juhe.cn/weather/index?cityname=%E8%8B%8F%E5%B7%9E&key=您申请的KEY

请求参数说明：

名称必填类型说明

citynameYstring城市名，如："苏州"，需要utf8 urlencode

dtypeNstring返回数据格式：json或xml,默认json

formatNint未来7天预报(future)两种返回格式，1或2，默认1

keyYstring您申请到的访问密钥

返回数据示例：

2、实现过程

上面的案例中，我们需要模拟接口服务器返回天气信息来进行APP测试，具体实现步骤如下：

(1)按照提供的“返回数据示例”格式准备好测试数据，并保存为weather_response.json文件。

(2)打开fiddler，开启自动响应功能，添加并编辑匹配规则，指定响应文件，如下图所示：

(3)在浏览器地址栏中输入 http://v.juhe.cn/weather/index?cityname=北京&key=您申请的KEY 进行效果测试，效果如下图所示：
