411/412 error while using tus-java-client #124
Description
Question
We have a tusdotnet server and tus-js which is working perfectly fine. We are planning to add a tus-java-client as well for our product and have developed a simple java application to test the tus-java-client but, I'm consistently receiving 411 error. after looking at this article and followed the instructions and now I'm receiving 412 error. I'm not sure what headers I'm missing because I'm using the same headers from tus-js. Any help is appreciated
Thanks

- Used tus server software: [tusdotnet]
package com.example;
import io.tus.java.client.TusClient;
import io.tus.java.client.TusUpload;
import io.tus.java.client.TusUploader;
import org.apache.log4j.Logger;
import java.io.File;
import java.net.URL;
import java.util.Base64;
import java.util.HashMap;
import java.util.Map;
public class App {
static final Logger logger = Logger.getLogger(App.class);
public static void main(String[] args) {
try {
System.setProperty("sun.net.http.allowRestrictedHeaders", "true");
// File path and server URL
String filePath = "C:\\myfile\\path.jpg";
URL uploadURL = new URL("MyURL");
// Initialize the TUS client
TusClient client = new TusClient();
client.setUploadCreationURL(uploadURL);
// Prepare the file
File file = new File(filePath);
if (!file.exists()) {
logger.error("File not found: " + filePath);
return;
}
long fileSize = file.length();
// Set headers
Map<String, String> headers = new HashMap<>();
headers.put("Tus-Resumable", "1.0.0");
headers.put("Upload-Length", String.valueOf(fileSize));
headers.put("X-Token", "<Your-Actual-Token>");
logger.debug("Headers set: " + headers);
client.setHeaders(headers);
// Create the upload
TusUpload upload = new TusUpload(file);
upload.setSize(fileSize);
// Set metadata
Map<String, String> metadata = new HashMap<>();
metadata.put("filename", file.getName());
metadata.put("filetype", "image/jpeg");
// Set additional metadata as observed
//Metadata added here
// Encode metadata
StringBuilder encodedMetadata = new StringBuilder();
for (Map.Entry<String, String> entry : metadata.entrySet()) {
if (encodedMetadata.length() > 0) {
encodedMetadata.append(",");
}
String encodedValue = Base64.getEncoder().encodeToString(entry.getValue().getBytes("UTF-8"));
encodedMetadata.append(entry.getKey()).append(" ").append(encodedValue);
}
headers.put("Upload-Metadata", encodedMetadata.toString());
// Create and start the upload process
TusUploader uploader = client.createUpload(upload);
uploader.setChunkSize(1024 * 1024); // 1MB chunk size
logger.info("Starting upload process.");
while (uploader.uploadChunk() > -1) {
long uploadedBytes = uploader.getOffset();
logger.info(String.format("Uploaded %d of %d bytes", uploadedBytes, fileSize));
}
uploader.finish();
logger.info("Upload completed successfully!");
} catch (Exception e) {
logger.error("Failed to complete upload", e);
}
}
}
This is my Error
