Как загрузить файл по определенному пути Ubuntu, используя HttpClient

Question

Я получаю ошибку 404 при загрузке файла на мой сервер Ubuntu.

public class Test {

    public static void main(String[] args) throws ClientProtocolException, IOException {
        // TODO Auto-generated \ stub

        CloseableHttpClient httpClient = HttpClients.createDefault();
        UsernamePasswordCredentials creds = new UsernamePasswordCredentials("user", "password");
        System.out.println(creds.getUserPrincipal().getName());
        System.out.println(creds.getPassword());
        HttpPost uploadFile = new HttpPost("http://10.0.0.45/home");


        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.addTextBody("field1", "yes", ContentType.TEXT_PLAIN);

        // This attaches the file to the POST:
        File f = new File("D:\\chinta\\abc.txt");
        builder.addBinaryBody(
            "file",
            new FileInputStream(f),
            ContentType.APPLICATION_OCTET_STREAM,
            f.getName()
        );

        HttpEntity multipart = builder.build();
        uploadFile.setEntity(multipart);
        CloseableHttpResponse response = httpClient.execute(uploadFile);
        System.out.println("=s========================"+response.getStatusLine());

        HttpEntity responseEntity = response.getEntity();
    }

}

Я получаю ошибку 404 в response.getstatus.

Я попробовал твой код, и он работает нормально.404 обычно означает, что URL-адрес запроса не существует на стороне сервера.Может, тебе стоит это проверить.
