放心java中使用JSONpath来提取数组中的数据

Question

该函数包含API，我可以在其中获取JSON格式的值。但我想获取JSON中存在的确切ID=2如何使用JavaJSON路径获取该数据。我必须使用maven依赖项。该函数包含API，我可以在其中获取JSON格式的值。但我想获取JSON中存在的确切ID=2如何使用JavaJSON路径获取该数据。我必须使用maven依赖项。

这个响应帮助我从每个数据中找到键值。

Answer 1

有 2 个 JsonPath：

• JsonPath Rest-Assured：

JsonPath jsonpath= response.jsonPath();
int id = jsonPath.getInt("data[1].id");
System.out.println(id); //2

• JsonPath Jayway：

int id = com.jayway.jsonpath.JsonPath.read(response.asString(), "$.data[1].id");
System.out.println(id); //2
