用到了Gson的JsonParser
maven项目引入
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.8.3</version>
</dependency>
字符串 :
//得到服务器返回的具体内容 final String res = response.body().string();
{"code":100,"msg":"处理成功!","extend":{"jsonString":{"userId":1,"userName":"123","userPwd":"123"}}}
jsonObject = (JsonObject) new JsonParser().parse(res).getAsJsonObject();
获取 code: jsonObject.get("code").getAsInt();获取 userName:
jsonObject.get("extend").getAsJsonObject().get("jsonString").getAsJsonObject().get("userName").getAsString()
