Getting error while posting tar.gz file using http client but works fine with curl command

Abdul :

Please find the sender class below

private static CloseableHttpClient httpClient() {
        try {
            TrustStrategy acceptingTrustStrategy = (certificate, authType) -> true;
            SSLSocketFactory sf = new SSLSocketFactory(acceptingTrustStrategy, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
            Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                    .register("http", PlainConnectionSocketFactory.INSTANCE)
                    .register("https", sf)
                    .build();
            PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(registry);
            connectionManager.setMaxTotal(maxTotalConnections);
            connectionManager.setDefaultMaxPerRoute(maxConnectionsPerRoute);
            CloseableHttpClient defaultHttpClient = HttpClientBuilder.create()
                    .setConnectionManager(connectionManager)
                    .setDefaultRequestConfig(RequestConfig.DEFAULT)
                    .build();

            return defaultHttpClient;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

    static String authHeaders(String username, String password ){

        String auth = username + ":" + password;
        String authHeader = "Basic " + auth;
        return authHeader;
    }



    public static void main(String[] args) {
        try{
            CloseableHttpClient httpClient = httpClient();
            HttpPost postRequest = new HttpPost("https://localhost:8018/receiver?filename=data.tar.gz");
            //postRequest.addHeader(HttpHeaders.TRANSFER_ENCODING, "chunked");
            postRequest.addHeader(HttpHeaders.AUTHORIZATION, authHeaders("test","test") );
            postRequest.addHeader(HttpHeaders.CONTENT_ENCODING, "gzip");
            File file = new File(Receiver.class.getClassLoader().getResource("data.tar.gz").getFile());
            MultipartEntityBuilder builder = MultipartEntityBuilder.create();

            builder.addPart("data.tar.gz", new FileBody(file, "application/x-gzip"));

            postRequest.setEntity(builder.build());

//            MultipartEntity multipart = new MultipartEntity();
//            ContentBody fileContent = new FileBody(file); //For tar.gz: "application/x-gzip"
//            multipart.addPart("data.tar.gz", fileContent);
//            postRequest.setEntity(multipart);

            HttpResponse response = httpClient.execute(postRequest);
            System.out.println(response);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

I am trying to post gzip file through http client and getting below error

Getting error while posting tar.gz file using http client but If I post the same file using curl command it works fine and executes properly but while passing through http client throws error.

Curl command

curl -u test:test --insecure -T ./data.tar.gz -v -X POST  --header "Content-Encoding: gzip" 'https://localhost:8018/receiver?filename=data.tar.gz'

Please check and let me know what I am missing and I tried to search and got some details and implemented using the same but not yet got a solution.

Abdul :

We need to enable chunked to resolve the issue.

File file = new File(CallHttpReceiver.class.getClassLoader().getResource(fileName).getFile());
FileEntity fileEntity = new FileEntity(file);
fileEntity.setChunked(true);   
postRequest.setEntity( fileEntity );

We need to make our fileEntity as chunked to pass the gzip as a request and it worked for me . Thanks to all who supported and tried to provide result for me.
