Question

我使用com.jcraft.jsch.JSch创建SFTP连接。

我的SSH密钥设置为我能够在没有用户名或密码的情况下直接SSH到服务器的地方。

ssh test_server

我的公钥位于me@test_server:~/.ssh/中的authorized_key文件中我本地计算机上的SSH密钥位于C:\cygwin\home\me\.ssh\
另外，我还在此目录中有一个配置文件和一个known_hosts文件。

Host test_server
User user_name
HostName test_server.domain.com
ForwardAgent yes

要仔细检查，我确保C:\cygwin\home\me\.ssh中的公钥位于远程服务器的authorized_keys文件中。

我正在开发一个创建文件的GUI程序。使用该文件，我希望能够将其存储在远程服务器上，并将其放在SFTP的文件夹中。我怎么能这样做？

这是我到目前为止所拥有的：

public static void main(String[] arg) {
    try {
        JSch jsch = new JSch();

        String user = "";
        String host = "test_server";
        int port = 22;
        String privateKey = "C:/cygwin/home/me/.ssh/id_rsa";

        jsch.addIdentity(privateKey);
        System.out.println("identity added ");

        Session session = jsch.getSession("", host);
        System.out.println("session created.");

        session.connect();
        System.out.println("session connected.....");

        Channel channel = session.openChannel("sftp");
        channel.setInputStream(System.in);
        channel.setOutputStream(System.out);
        channel.connect();
        System.out.println("shell channel connected....");

        ChannelSftp c = (ChannelSftp) channel;

        String fileName = "test.txt";
        c.put(fileName, "./in/");
        c.exit();
        System.out.println("done");

    } catch (Exception e) {
        System.err.println(e);
    }
}

我一直收到

com.jcraft.jsch.JSchException：验证失败错误。

有没有人知道这方面的解决方案？

附加信息（这可能有用......不确定）：
当我打开cmd时，我需要C:\Users\me。
但是当我通过＆＃34; pwd＆＃34;命令，打印出/cygdrive/c/Users/me 我也对任何新图书馆开放，或者也许只是更好的方式来做这件事。

非常感谢你！

Answer 1

您未在<span *ngFor="let subject of [(mySubject | async)]" [ngClass]="{greenClass: isPositive(subject?.fieldData), redClass: !isPositive(subject?.fieldData)}"> {{subject?.fieldData | number:'1.0-1' }} </span>命令行上明确指定用户名这一事实并不意味着没有使用用户名。

默认情况下，ssh会隐式使用本地用户名。 JSch不会这样做。您必须明确指定用户名，即使它与本地用户名相同。

使用JSch
