【軟件測試基礎知識】如何使用fiddler模擬接口服務器

1、案例描述

案例：我們的APP使用了某天氣預報接口，其接口描述如下：

接口名稱：根據城市名查詢天氣

接口地址：http://v.juhe.cn/weather/index

返回格式：json/xml

請求方式：get

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

請求參數說明：

名稱必填類型說明

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

dtypeNstring返回數據格式：json或xml,默認json

formatNint未來7天預報(future)兩種返回格式，1或2，默認1

keyYstring您申請到的訪問密鑰

返回數據示例：

2、實現過程

上面的案例中，我們需要模擬接口服務器返回天氣信息來進行APP測試，具體實現步驟如下：

(1)按照提供的“返回數據示例”格式準備好測試數據，并保存為weather_response.json文件。

(2)打開fiddler，開啟自動響應功能，添加并編輯匹配規則，指定響應文件，如下圖所示：

(3)在瀏覽器地址欄中輸入 http://v.juhe.cn/weather/index?cityname=北京&key=您申請的KEY 進行效果測試，效果如下圖所示：
