【Jmeter测试】如何使用BeanShell断言判断请求返回的Json相应结果

脚本结构

上图中，queryMaterialApiDTOListByPkIds是返回Json格式响应结果的请求，然后添加BeanShell断言详细判断Json结果中的值是否正确。

Json格式的相应结果

BeanShell脚本

 1 import org.json.JSONObject;
 2 import org.json.JSONArray;
 3 
 4 String result = prev.getResponseDataAsString();
 5 
 6 JSONObject response = new JSONObject(result);
 7 JSONArray array = response.getJSONArray("data");
 8 
 9 if (array.length() != 2) {
10   Failure=true ;
11   FailureMessage ="array size < 2";
12   return;
13 }
14 
15 int count = 0;
16 for (int i = 0; i < 2; i++) {
17   JSONObject temp = array.getJSONObject(i);
18   String pkId = temp.get("pkId").toString();
19   if (pkId.equals("6902265111719")) {
20       
21       if (!temp.get("materialCode").equals("6902265111719")) {
22           Failure=true ;
23           FailureMessage ="pkId: " + pkId + ", material code error, code = " + temp.get("materialCode");
24           return;
25       }
26 
27       if (!temp.get("materialName").equals("海天蒸鱼豉油450ml*12")) {
28           Failure=true ;
29           FailureMessage ="pkId: " + pkId + ", material name error, name = " + temp.get("materialName");
30           return;
31       }
32       count++;
33   }
34 
35   if (pkId.equals("6902265113003")) {
36       if (!temp.get("materialCode").equals("6902265113003")) {
37           Failure=true ;
38           FailureMessage ="pkId: " + pkId + ", material code error, code = " + temp.get("materialCode");
39           return;
40       }
41 
42       if (!temp.get("materialName").equals("海天特辣黄豆酱230g*15")) {
43           Failure=true ;
44           FailureMessage ="pkId: " + pkId + ", material name error, name = " + temp.get("materialName");
45           return;
46       }
47       count++;
48   }
49 }
50 
51 if (count != 2) {
52   log.info("count != 2");
53   Failure=true ;
54   FailureMessage ="pkId not in range";
55   return;
56 }
57 
58 log.info(array.toString())

1、先通过prev.getResponseDataAsString获取到响应的返回结果，然后通过org.json.JSONObject和org.json.JSONArray两个类来解析返回的相应结果。
2、解析出想要的Json对象后，在for循环中对Json对象中每一个需要检测的值和期望的进行比对，如果不正确，Failure设置为true，FailureMessage设置具体的错误信息。
3、for循环中有可能一开始的pkId取值就和期望不一致，所以这时需要计算下遍历的计数count，如果计数和期望的不一致，说明响应结果和期望结果的数量不一致。
