java - TUSClient 是否支持代理

Question

请考虑以下代码。我们正在使用 TUSClient 分块上传大文件。

public void uploadFile(UploadFileResponse uploadFileResponse, File file) {

        try {
            if (System.getProperty("sun.net.http.allowRestrictedHeaders") == null) {
                System.setProperty("sun.net.http.allowRestrictedHeaders", "true");
            }
            byte[] bytes = Files.readAllBytes(file.toPath());

            Map headers = new HashMap();
            headers.put("token", getToken());
            headers.put("Content-Length", Integer.toString(bytes.length));


            final TusUpload upload = new TusUpload(file);
            TusClient client = new TusClient();
            client.setUploadCreationURL(new URL(uploadFileResponse.getUploadUrl()));
            client.setHeaders(headers);
            client.enableResuming(new TusURLMemoryStore());

            Integer chunkSize = 1024 * 1024 * 1;

            Map metadata = new HashMap();
            metadata.put("name", file.getName());
            metadata.put("chunkSize", String.format("%d", chunkSize));
            metadata.put("contentType", "text/xml");
            upload.setMetadata(metadata);
            
            TusExecutor executor = new TusExecutor() {
                @Override
                protected void makeAttempt() throws IOException, ProtocolException {

                    TusUploader uploader = client.resumeOrCreateUpload(upload);
                    uploader.setChunkSize(chunkSize);
                    int result = 0;
                    do {
                        result = uploader.uploadChunk();
                    } while (result > -1);

                    uploader.finish();
                }
            };
            executor.makeAttempts();
        }catch (Exception e){
            throw new customException(e);
        }
    }

现在上面的代码在没有代理的环境中工作。现在如果需要代理支持，如何在 TUSClient 中添加代理支持。
