java - 放心: Size of json response

Question

我是新人，放心。我已尝试使用以下代码来获取响应

@Test
    public void getData() throws IOException {
         Response response = 
                    given().
                        header("authToken",userToken).
                    when().
                        get("/students").
                    then().
                        contentType(ContentType.JSON).
                    extract().
                        response(); 
                    String jsonStr = response.getBody().asString();
                    System.out.println("Tag List************************" + jsonStr);

        }

这是 json 响应

{"max":"20","list":[
{"id":1120,"sId":1120,"sIntId":"150","type":1},
{"id":1121,"sId":1121,"sIntId":"151","type":1}
{"id":1122,"sId":1122,"sIntId":"152","type":1}
{"id":1123,"sId":1123,"sIntId":"153","type":1}
{"id":1124,"sId":1124,"sIntId":"154","type":1}]}

如何计算id 或列表的大小。帮助我。

您不必提取响应来验证这一点。你可以这样做:

given().
       header("authToken",userToken).
when().
       get("/students").
then().
       contentType(ContentType.JSON).
       body("list.size()", is(5));

但是如果您想从响应中提取它，您也可以:

Response response = 
given().
       header("authToken",userToken).
when().
       get("/students").
then().
       contentType(ContentType.JSON).
extract().
       response(); 
int sizeOfList = response.body().path("list.size()");

如果您只对列表的大小感兴趣，而没有其他兴趣，则可以这样做:

int sizeOfList = 
given().
       header("authToken",userToken).
when().
       get("/students").
then().
       contentType(ContentType.JSON).
extract().
       path("list.size()");
