我正在尝试使用 org.json.JSONObject 库从 json 响应中提取特定数据这是我的 json 响应:
{
"facets": {
"application": [
{
"name": "38",
"distribution": 1
}
],
"node": [
{
"name": "frstlwardu03_05",
"distribution": 1
}
],
"area": [
{
"name": "x",
"distribution": 1
}
],
"company": [
{
"name": "war001",
"distribution": 1
}
]
},
"duObjects": [
{
"id": "TASK|TSK(ZRM760J)(000)(ZRM760JU00)(000)|ZSRPSRM000",
"name": "TSK(ZRM760J)(000)(ZRM760JU00)(000)",
"mu": "ZSRPSRM000",
"label": "",
"session": "ZRM760J|000",
"sessionLabel": "SAP SRM Achats frais generaux execution",
"uprocHeader": "ZRM760JU00|000",
"uprocHeaderLabel": "Header for SRM760J",
"uprocHeaderType": "CL_INT",
"domain": "M",
"domainLabel": "",
"application": "38",
"applicationLabel": "magasin",
"highlightResult": {
"name": "name",
"word": "TSK"
}
}
],
"totalCount": 1,
"pageSize": 10,
"pageCurrent": 1,
"pageNb": 1
}
这是我用来将 URL 调用转换为 jsonobject 的方法:
public static JSONObject readJsonFromUrl(String url) throws IOException, JSONException
{
InputStream is = new URL(url).openStream();
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-
8")));
String jsonText = readAll(rd);
JSONObject json = new JSONObject(jsonText);
return json;
} finally {
is.close();
}
}
当我调用此方法时,我能够获取 Duobject 中的数据:
public static void main(String[] args) throws IOException, JSONException {
JSONObject json = readJsonFromUrl("http://frstmwarwebsrv.orsyptst.com:9000/duobject?
searchString=TSK(ZRM760J)(000)(ZRM760JU00)
(000)&filterchecks=nameJob,nameWF,nameSWF,application,domain&p.index=0&p.size=10");
System.out.println(json.getJSONArray("duObjects"));
}
无论如何我只能提取 DuObjects 的名称字段吗?
