Java 如何在Secure_CRT上远程编辑zip中的文件？

我的任务是在SecureCRT上编辑zip内的文件。 我能够使用JSCH库（com.jcraft.JSCH）远程运行Linux命令

以下是我的部分代码：

 Session session = setUpSession(testParameters, softAsserter);
                Channel channel = session.openChannel("exec");
                ((ChannelExec)channel).setCommand(command);
                channel.setInputStream(null);
                ((ChannelExec)channel).setErrStream(System.err);
                InputStream inputStream = channel.getInputStream();                    
                channel.connect();

我想知道在SecureCRT服务器上编辑zip文件中的文件（例如Test.txt）的最佳方法或正确命令是什么。

可以通过多种方式修改zip文件中的内容

我已经提到了一些可能对你有用的方法。为了做到这一点

我们应该将源文件/编译文件从本地计算机安全地传输到服务器。下面的链接将有助于安全地传输文件

作为第一步，我们应该开发一个能够修改zip文件内容的代码段，然后将该文件复制到服务器。然后我们执行命令来运行该文件，以便修改zip中的竞争

下面提到的方法只是为了修改zip争用

方法1：使用简单的Java代码段实现

我们可以编写一个简单的java代码段，它可以打开zip文件并进行编辑，将文件保存在机器中，然后通过运行“java文件名”来执行类文件，该文件实际上会修改zip文件中的内容

链接将有助于：

方法2：使用python修改zip文件

方法3：编写一个shell脚本来直接修改zip文件的内容，这样我们就可以将shell脚本复制到服务器上，然后直接执行shell脚本。

下面的代码片段将帮助您使用库进行连接和执行

谢谢你详细的回答，朋友。您的Java代码中是否有一种方法在远程Linux服务器上的Zip中编辑文件？更新了“Apporach 1”中的该部分代码片段，使用该代码片段，您可以使用Java编辑Zip文件中的文本文件。我可以从远程服务器读取Zip中的文件并对其进行编辑吗？我们真的不必这样做，当我们将源代码复制到目标计算机时，运行源代码将编辑文件。在本例中，我们必须将“RemoteEditFileContends”类文件复制到远程计算机，然后使用命令“java RemoteEditFileContends”运行“RemoteEditFileContends”，以便在zip contends中编辑该文件。
