如果返回的數據是JSON格式的，我們可以用JSON提取器來提取需要的字段，這樣更簡單一點，
老司機你懂的：https://item.taobao.com/item.htm?id=613711271112
JSON主要運用於返回JSON格式的,格式：$.data[0].id $.data.xx1。
提取器要放到http請求下面：
-
Variable names：保存的變量名，后面使用${Variable names}引用
-
JSON Path expressions：調試通過的json path表達式
-
Match Numbers：匹配數字（0代表隨機，1代表第一個，-1代表所有）
-
Default Values：找不到時默認值，一般設置為NOT FOUND
-
Compute concatenation var(suffix_ALL)：是否統計所有，即將匹配到的所有值保存，名為“變量名_ALL”
示例：

現在我們來提取職位的positionURL字段：
1、在查看結果樹中通過JSON Path Tester來調試json path
2、添加JSON提取器，設置正確的參數，獲取第一個positionURL
輸出結果：
3、獲取所有的positionURL
輸出結果：
4、把所有的positionURL放到一個字段中
輸出結果：
5、一次性提取多個字段，比如我們要提取第一個職位的jobName;salary;positionURL三個字段
輸出結果：
