如何从具有多个节点的 json 中提取特定数据?
How to extract specific data from json with multiple nodes?
- 将 java 与硒一起使用
- 我已经在我的代码
中捕获了完整的 json
- 在我的 json 中有两个节点 "Service1" 和 "Service2"
- 我的要求是获取 "Services1" 节点的详细信息 --> 数据节点
- 但我无法仅提取具有数据节点详细信息的 Service1(我不想要 "test" 节点详细信息。
问题:能否请您帮我从 Service1 中提取数据 - 数据节点仅使用 java 代码?我正在使用带有 java.I 的硒,其中一个脚本需要这个。
Actual response:
{
"Service1": [
{
"data": {
"status": false,
"type": "A",
"order": 1,
"Version": "v6"
},
"test": {
"ModuleID": "123456",
"BoxID": "a777",
"Url": "https://google.com"
}
},
{
"data": {
"status": true,
"type": "B",
"order": 1,
"Version": "v2"
},
"test": {
"ModuleID": "123456",
"BoxID": "a777",
"Url": "https://google.com"
}
}
],
"Service2": {
"data1": {
"status": false,
"type": "c",
"order": 1,
"Version": "v6"
},
"dashboard": {
"ModuleID": "123456",
"BoxID": "a777",
"Url": "https://google.com"
}
}
}
Expected data :
[
{
"status": false,
"type": "A",
"order": 1,
"Version": "v6"
},
{
"status": true,
"type": "B",
"order": 1,
"Version": "v2"
}
]
获取所需数据是基于api响应。但是在获取数据的结果中,您可以根据需要在 java 中将其转换为:
主题:
JSONObject response = new JSONObject("json data");//replace json data with your given json data
JSONArray service1 = response.getJSONArray("Service1");
JSONObject firstObjectInService1 = service1.getJSONObject(0);
JSONObject secondObjectInService1 = service1.getJSONObject(1);
JSONObject dataInFirstObject = firstObjectInService1.getJSONObject("data");
JSONObject dataInSecondObject = secondObjectInService1.getJSONObject("data");
完整代码片段:
import org.json.*;
public class JsonParsing {
public static void main(String[] args) {
String jsonData = "{\n" +
"\"Service1\": [\n" +
" {\n" +
" \"data\": {\n" +
" \"status\": false,\n" +
" \"type\": \"A\",\n" +
" \"order\": 1,\n" +
" \"Version\": \"v6\"\n" +
" },\n" +
" \"test\": {\n" +
" \"ModuleID\": \"123456\",\n" +
" \"BoxID\": \"a777\",\n" +
" \"Url\": \"https://google.com\"\n" +
"\n" +
" }\n" +
"\n" +
" },\n" +
" {\n" +
" \"data\": {\n" +
" \"status\": true,\n" +
" \"type\": \"B\",\n" +
" \"order\": 1,\n" +
" \"Version\": \"v2\"\n" +
" },\n" +
" \"test\": {\n" +
" \"ModuleID\": \"123456\",\n" +
" \"BoxID\": \"a777\",\n" +
" \"Url\": \"https://google.com\"\n" +
"\n" +
"\n" +
" }\n" +
" }\n" +
"\n" +
"],\n" +
"\"Service2\": {\n" +
" \"data1\": {\n" +
" \"status\": false,\n" +
" \"type\": \"c\",\n" +
" \"order\": 1,\n" +
" \"Version\": \"v6\"\n" +
" },\n" +
" \"dashboard\": {\n" +
" \"ModuleID\": \"123456\",\n" +
" \"BoxID\": \"a777\",\n" +
" \"Url\": \"https://google.com\"\n" +
"\n" +
" }\n" +
"}\n" +
"}";
System.out.println(jsonData);
try {
JSONObject response = new JSONObject(jsonData);//replace json data with your given json data
JSONArray service1 = response.getJSONArray("Service1");
JSONObject firstObjectInService1 = service1.getJSONObject(0);
JSONObject secondObjectInService1 = service1.getJSONObject(1);
JSONObject dataInFirstObject = firstObjectInService1.getJSONObject("data");
JSONObject dataInSecondObject = secondObjectInService1.getJSONObject("data");
System.out.println(dataInFirstObject);
System.out.println(dataInSecondObject);
} catch (JSONException je) {
//do what you want
}
}
}
所以最后在 dataInFirstObject 中我们有:
{
"status": false,
"type": "A",
"order": 1,
"Version": "v6"
}
我们有 dataInSecondObject:
{
"status": true,
"type": "B",
"order": 1,
"Version": "v2"
}
你可以使用 JSON simple library ,它是用于 read/write/parse JSON 中数据的库 file.In 这个例子我从 JSON 文件中读取数据而不是JSON直接内容。
private void findData() {
ArrayList<String> dataArrayList=new ArrayList<>();
try {
JSONParser parser = new JSONParser();
InputStream in = getClass().getResourceAsStream("/json/Services.json");
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
Object obj = parser.parse(reader);
JSONObject jsonObject = (JSONObject) obj;
JSONArray msg = (JSONArray) jsonObject.get("Service1");
Iterator<JSONObject> iterator = msg.iterator();
while (iterator.hasNext()) {
JSONObject jsonObjectData = iterator.next();
JSONObject dataObject = (JSONObject) jsonObjectData.get("data");
System.out.println(dataObject);
//Extract values
dataObject.values().stream().forEach(value->{
System.out.println(value);
dataArrayList.add(value.toString());
});
}
} catch (IOException | org.json.simple.parser.ParseException ex) {
Logger.getLogger(CorporationRegistrationFormController.class.getName()).log(Level.SEVERE, null, ex);
}
}
如果您需要阅读代码中的 JSON 内容,只需将 reader 替换为您的内容,如下所示:Object obj = parser.parse("JSON content");
