我正在尝试解析JSON以下并寻找“zip-code”值“526262”。我是Java的新手并且很难获得邮政编码的价值吗?
这是我的JSON:
{
"id": "6fffdfdf-8d04-4f4e-b746-20930671bd9c",
"timestamp": "2017-07-21T03:51:27.329Z",
"lang": "en",
"result": {
"source": "testsrc",
"resolvedQuery": "testquery",
"action": "test",
"actionIncomplete": true,
"parameters": {
"zip-code": "526262"
}
}
}
这是我的Java代码:
String test= "{\n" +
"\t\"id\": \"6fffdfdf-8d04-4f4e-b746-20930671bd9c\",\n" +
"\t\"timestamp\": \"2017-07-21T03:51:27.329Z\",\n" +
"\t\"lang\": \"en\",\n" +
"\t\"result\": {\n" +
"\t\t\"source\": \"testsrc\",\n" +
"\t\t\"resolvedQuery\": \"testquery\",\n" +
"\t\t\"action\": \"test\",\n" +
"\t\t\"actionIncomplete\": true,\n" +
"\t\t\"parameters\": {\n" +
"\t\t\t\"zip-code\": \"526262\"\n" +
"\t\t}\n" +
"\t}\n" +
"}";
JSONObject request = new JSONObject(test);
String zipCode = request.getJSONObject("result").get("parameters").toString();
System.out.println("zipCode is : " + zipCode);
但是我的输出低于输出:
zipCode is : {"zip-code":"526262"}
如何单独获取邮政编码价值?
有人可以帮助如何在java中获取此值吗?

获取parameters
时应该使用getJSONObject,以便继续使用JSONObject API深入挖掘。
request.getJSONObject("result").getJSONObject("parameters").getString("zip-code");

request.getJSONObject("result").get("parameters").getString("zip_code")
将解决您的问题。构建JSON对象以处理嵌套。
