【Jmeter測試】如何使用BeanShell斷言判斷請求返回的Json相應結果

• 腳本結構
  
  上圖中，queryMaterialApiDTOListByPkIds是返回Json格式響應結果的請求，然後添加BeanShell斷言詳細判斷Json結果中的值是否正確。

  1、先通過prev.getResponseDataAsString獲取到響應的返回結果，然後通過org.json.JSONObject和org.json.JSONArray兩個類來解析返回的相應結果。
  2、解析出想要的Json對象後，在for循環中對Json對象中每一個需要檢測的值和期望的進行比對，如果不正確，Failure設置爲true，FailureMessage設置具體的錯誤信息。
  3、for循環中有可能一開始的pkId取值就和期望不一致，所以這時需要計算下遍歷的計數count，如果計數和期望的不一致，說明響應結果和期望結果的數量不一致。
