Hi Folks,

 

I am trying to get Splunk response from java using below method

----------------

public String executeSearch(String searchQuery) throws IOException {
//String apiUrl = hostName + "/__raw/services/search/jobs/export?search=" + URLEncoder.encode(searchQuery, "UTF-8").replace("+", "%20");
String apiUrl = hostName + "/__raw/services/search/jobs/export?search=" + URLEncoder.encode(searchQuery, "UTF-8")
.replace("+", "%2B")
.replace("%3D", "=")
.replace("%20", "+")
.replace("%2A", "*")
.replace("%3F", "?")
.replace("%40", "@")
.replace("%2C", ",");

URL url = new URL(apiUrl);
System.out.println("Value of Splunk URL is " + url);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");

String credentials = userName + ":" + password;
String encodedCredentials = Base64.getEncoder().encodeToString(credentials.getBytes());
connection.setRequestProperty("Authorization", "Basic " + encodedCredentials);

StringBuilder response = new StringBuilder();
try (BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()))) {
String inputLine;
while ((inputLine = in.readLine()) != null) {
System.out.println("Response Line: " + inputLine); // Print each line of the response
response.append(inputLine);
}
}
return response.toString();
}




public static void main(String[] args) {
if (args.length < 10) {
System.out.println("Insufficient arguments provided. Please provide all required arguments.");
System.exit(1); // Exit with error code 1
}

String hostName = args[0];
String userName = args[1];
String password = args[2];
String query = args[3];
String logFileLocation = args[4];
String fileName = args[5];
String fileType = args[6];
String startDate = args[7];
String endDate = args[8];
String time = args[9];

try {
SplunkRestClient client = new SplunkRestClient(hostName, userName, password);
String searchResult = client.executeSearch(query);
System.out.println(searchResult);

// Write search result to file
String filePath = logFileLocation + File.separator + fileName + "." + fileType;
Files.write(Paths.get(filePath), searchResult.getBytes());

// Check if file is empty
File file = new File(filePath);
if (file.length() == 0) {
System.out.println("File is empty. Deleting...");
if (file.delete()) {
System.out.println("File deleted successfully.");
} else {
System.out.println("Failed to delete file.");
}
} else {
// Validate file contents (assuming JSON data)
try {
new JSONObject(new String(Files.readAllBytes(Paths.get(filePath))));
System.out.println("File contents are valid JSON.");
} catch (Exception e) {
System.out.println("File is corrupt. Deleting...");
/*if (file.delete()) {
System.out.println("Corrupt file deleted successfully.");
} else {
System.out.println("Failed to delete corrupt file.");
}*/
}
}

} catch (IOException e) {
System.out.println("Error occurred while executing search: " + e.getMessage());
System.exit(2); // Exit with error code 2
}
}
