我正在尝试使用 JSCH 通过 SFTP 协议发送文件。

这是FileService文件

public class FileService {

    public void send(){
        String str = "this is a test";
        InputStream is = new ByteArrayInputStream(str.getBytes(StandardCharsets.UTF_8));
        try {
            var channel = setupJsch();
            channel.put(is, "test.txt");
        } catch (JSchException | SftpException e) {
            e.printStackTrace();
        }
    }
    
    private ChannelSftp setupJsch() throws JSchException {
        JSch jsch = new JSch();
        Session jschSession = jsch.getSession("foo", "localhost", 2222);
        jschSession.setPassword("pass");
        jschSession.setConfig("StrictHostKeyChecking", "no");
        jschSession.connect();
        return (ChannelSftp) jschSession.openChannel("sftp");
    }
}

但正在JSch抛出NullPointException一条消息： java.lang.NullPointerException: Cannot invoke "com.jcraft.jsch.Channel$MyPipedInputStream.updateReadSide()" …

我有一个包含这样的数据的列表

ID  |   START_DATE          |   END_DATE                |   Chapter     |   ID_OWNER
1       01/03/2013 05:15:14     01/03/2013 06:20:14         1               1
1       01/03/2013 06:25:33     01/03/2013 06:40:11         2               1

我想创建一个像这样的字典:

Dictionary<int, Dictionary<string,int>
Dictionary<ID, Dictionary<START_DATE.Date, Total of …

我想制作一个可以提供任何扩展文件的 api。像这样：http://localhost/download/[file].[extension]

这是我的代码，但它间歇性地给出以下消息：发送后无法设置标头。

  var express = require('express');
  var app = express();

  app.get('/download/:fileName/:extension', function(req, res){
    var file = __dirname + '/' + req.params.fileName + '.' + req.params.extension;
    res.download(file, function(err){
        if (err) {
          res.sendStatus(404);
        }
      res.end();
    }); 
  });

  var server = app.listen(3000, function () {
    var host = server.address().address;
    var port = server.address().port;

    console.log('app listening at http://%s:%s', host, port);
  });

My data looks like this

ID  |   START_DATE          |   END_DATE                |   Chapter
1       01/03/2013 05:15:14     01/03/2013 06:20:14         1
1       01/03/2013 06:25:33     01/03/2013 06:40:11         2
2       01/03/2013 05:01:34     01/03/2013 05:30:13         1
2       01/03/2013 05:31:20     01/03/2013 06:30:13         2
2       01/03/2013 06:32:20     01/03/2013 07:20:01         3
1       02/03/2013 05:15:14     01/03/2013 06:20:14         1
1       02/03/2013 06:25:33     01/03/2013 06:40:11         2

I want a result like this

ID  | Date          |       Total Duration
1       01/03/2013          Time in Minutes
1       02/03/2013          Time in Minutes
2       02/03/2013          Time in …

我正在开发一个 Windows Phone 8 应用程序，我有以下内容，Border但StackPanel没有StackPanel剪辑到Border

            <Border Grid.Column="1" BorderThickness="3" BorderBrush="Black" CornerRadius="50">
            <StackPanel Width="425">
                <StackPanel.Background>
                    <SolidColorBrush Color="#FFFBEAEA" Opacity="0.25"/>
                </StackPanel.Background>
                <TextBlock Text="{Binding Name}" Style="{StaticResource PhoneTextLargeStyle}" FontFamily="{StaticResource PhoneFontFamilySemiBold}" TextWrapping="Wrap" Margin="12,0,12,6" Foreground="Black"/>
                <TextBlock Text="{Binding Type}" Style="{StaticResource PhoneTextNormalStyle}" TextWrapping="Wrap" FontFamily="{StaticResource PhoneFontFamilySemiBold}" Foreground="Black"/>
                <TextBlock Text="{Binding Text}" Style="{StaticResource PhoneTextNormalStyle}" TextWrapping="Wrap" FontFamily="{StaticResource PhoneFontFamilySemiLight}" Foreground="Black"/>
            </StackPanel>
            </Border>

我不知道为什么我在网上做了一些挖掘，但这个示例不起作用。

有人可以帮助我吗？谢谢。
