从Response取值验证时遇JsonPath参数未定义错误求助

尝试从接口返回的Response对象中提取数据做结果验证时，抛出了IllegalArgumentException，提示参数"H96"未定义。

原代码 #

@And("^Delete record for member 0000000555for SC_1_1 scenario")
public void deleteClaimsInserted_SC_1_1() {

  Response deleteClaimsInsertedSC1 = SerenityRest.given().auth().oauth2(RestAssuredOAuth2.access_token_code)
           .header("platform", "DR2")
           .contentType("application/json")
           .header("Accept", "application/json")
           .queryParam("mbrId", "000000055564627500")
           .queryParam("custId", "444")
           .queryParam("clntId", "2")
           .queryParam("grpId", "1")
           .queryParam("bnftPrdBgnDt", "2019-01-01")
           .get(deleteClaimsURI)
           .then()
           .statusCode(200)
           .extract().response();


   int validateClaimsDeleteSuccess = deleteClaimsInsertedSC1.jsonPath().getInt("deleted H96 records");
   System.out.println(validateClaimsDeleteSuccess);
   if (validateClaimsDeleteSuccess > 0) {
       System.out.println(successfullDeletion);
   } else {
       System.out.println(failedDeletion);
   }


   softAssert.assertAll();
}

问题原因 #

RestAssured的JsonPath基于Groovy实现，当字段名包含空格或类似变量的字符（比如这里的"H96"）时，直接传入字段名会被Groovy解析为表达式，错误地将"H96"识别为未定义的变量，导致抛出异常。

解决方法 #

将包含空格的字段名用单引号包裹，或者使用方括号语法，让JsonPath正确识别为完整的字段名：

方式1：单引号包裹字段名

int validateClaimsDeleteSuccess = deleteClaimsInsertedSC1.jsonPath().getInt("'deleted H96 records'");

方式2：方括号语法

int validateClaimsDeleteSuccess = deleteClaimsInsertedSC1.jsonPath().getInt("[\"deleted H96 records\"]");

修改后，JsonPath会将整个字符串作为字段名解析，不会再把"H96"当成独立变量，即可正常提取数据。
