我在这里非常需要帮助，我尝试从文件中解析json。我从kibana开发工具中获得了这个json内容，我计划使用弹性api，获取json结果，并从json中获取多个字段。这是我的代码
public class JSONParserTest {
public static void main(String[] args) throws IOException, JSONException {
String the_json=readFile("/Users/ahmadasyary/Documents/sample.out", StandardCharsets.UTF_8);
//System.out.println(the_json);
JSONObject myjson = new JSONObject(the_json);
JSONArray the_json_array = myjson.getJSONArray("profiles");
}
static String readFile(String path, Charset encoding)
throws IOException
{
byte[] encoded = Files.readAllBytes(Paths.get(path));
return new String(encoded, encoding);
}
}
当我尝试运行它时，出现了这样的错误
Exception in thread "main" org.json.JSONException: Expected a ',' or '}' at 3264 [character 25 line 64]

这是来自kibana开发人员工具的json内容

我希望这个问题可以在无需对json内容进行任何手动更改的情况下解决，因为它是由kibana生成的

只需完全删除两次出现在关键字“ message”中的双引号：

"message": {"logMessageId":"","logTimestamp":"2019-03-22T10:52:46.251+07:00","transactionID":"H003190322105245739910520","serviceName":"","applicationID":"","logLevel":"AUDIT","logPoint":"Transaction-Audit","logMessage":"2019-03-22T10:52:45|2019-03-22T10:52:46|492|p0|H003190322105245739910520|p0169a3879784910520001101905fe5Sac000000000|TELKOMSEL||ACT|SELF|AIRTIME|0|||6281360791052|prepaid|Simpati|||prepaid|Simpati|22016||00011019|ML4_BP_22184|PO||Campaign|2019030761549|1|Days|5000.0|OT_002758_00011019_a5ffc884-19b1-11e9-80a8-cfff756b35c7|||Success|00000|Success||||002777:TC_002775_FLEXIBLEOFFER;00005679:TC_00005457_FLEXIBLEOFFER;00005696:TC_00005474_FLEXIBLEOFFER","requestPayload":"","responsePayload":"","processTime":"492"},
"hostname": "esbwnpapp3.telkomsel.co.id",
然后它应该可以工作，我可以使用下面的代码片段来解析文件。
import java.io.IOException;
import java.nio.charset.Charset;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Paths;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;
public class JSONParserTest {
public static void main(String[] args) throws ParseException, IOException {
String the_json=readFile("sample.out", StandardCharsets.UTF_8);
//System.out.println(the_json);
JSONParser object = new JSONParser();
Object obj = object.parse(the_json);
JSONObject myjson = (JSONObject)obj;
JSONArray the_json_array = (JSONArray)myjson.get("profiles");
System.out.println(the_json_array);
}
static String readFile(String path, Charset encoding)
throws IOException
{
byte[] encoded = Files.readAllBytes(Paths.get(path));
return new String(encoded, encoding);
}
}
