Question

将图像文件（jpg，png）发送到java中的smb

我添加了jcifs-1.3.19.jar。如上所述here和here

编辑：我已经使用此代码成功将jpeg图像发送到服务器上的共享文件夹，但速度非常慢，其发送速度接近1kb /秒。任何解决方案??

const http = require('http');
const url = require('url');

const fibonacciAsync = exports.fibonacciAsync = (n, done) => {
  if (n === 1 || n === 2) {
    done(1);
  } else {
    process.nextTick(() => {
      fibonacciAsync(n - 1, (val1) => {
        process.nextTick(() => {
          fibonacciAsync(n - 2, (val2) => {
            done(val1 + val2);
          })
        })
      })
    })
  }
}

http.createServer((req, res) => {
  const urlP = url.parse(req.url, true);
  let fibo;
  res.writeHead(200, {'Content-Type': 'text/plain'});
  if (urlP.query['n']) {
    fibo = fibonacciAsync(urlP.query['n']);
    res.end('Fibonacci ' + urlP.query['n'] + '=' + fibo);
  } 
}).listen(8124, '127.0.0.1');

最后这是解决方案：

  public boolean copyFiles(FileInputStream file, String fileName) {
            boolean successful = false;
            int cursor;
            SmbFileOutputStream sfos;
            SmbFile sFile;
            String path;
            NtlmPasswordAuthentication auth;
            try{
                String user = USER_NAME + ":" + PASSWORD;
                System.out.println("User: " + user);

                 auth = new NtlmPasswordAuthentication(user);
                StrictMode.ThreadPolicy tp = StrictMode.ThreadPolicy.LAX; StrictMode.setThreadPolicy(tp);

                 path = NETWORK_FOLDER + fileName+".jpeg";
                System.out.println("Path: " +path);

                 sFile = new SmbFile(path, auth);
                 sfos = new SmbFileOutputStream(sFile);

                long t0 = System.currentTimeMillis();

                byte[] b = new byte[8192];
                int n, tot = 0;
                Log.d("asdf","initiating : total="+tot);


                while((n = file.read(b))>0){
                    sfos.write( b, 0, n );
                    tot += n;
                    Log.d("asdf","writing : total="+tot);
                }
                successful = true;
                Log.d("asdf","Successful : total="+tot);

            }

            catch (Exception e) {
                successful = false;
                e.printStackTrace();
                Log.d("asdf","exxeption ");

            }
            return successful;
        }

如何在我的应用程序中将图像文件发送到NAS服务器？
