如何获取Java流以使ExpectIt驱动Telnet [英] How to get the Java stream for ExpectIt to drive Telnet

问题描述

如何获取用于telnet的Java流，以便与

How do I get the Java stream for telnet to use with the ExpectIt? Instead of using a Java library, such as Apache Telnet as below, using the actual Telnet client on Linux.

这是在期望的手册页的上下文中:

This is in the context of the man page from expect:

期望是一个与其他交互式程序对话"的程序根据脚本.

Expect is a program that "talks" to other interactive programs according to a script.

followup question with a much more narrow scope to a previous, vague, overly broad question where the following comment was made:

该库与其他所有Java库一样，都使用标准Java流可以来自Telnet客户端，套接字连接或任何其他流源.这是一个telnet示例:github.com/Alexey1Gavrilov/ExpectIt/blob/master/expectit-core/…–阿列克谢·加夫里洛夫(Alexey Gavrilov)

The library, as all the other Java libraries, uses standard Java streams which can come from a Telnet client, a socket connection, or any other stream source. Here is a telnet example: github.com/Alexey1Gavrilov/ExpectIt/blob/master/expectit-core/… – Alexey Gavrilov

推荐答案

您可以生成telnet客户端进程并连接到该进程的输入和输出流.像这样:

You can spawn a telnet client process and connect to the process's input and output streams. Something like:

        Process process = Runtime.getRuntime().exec("telnet rainmaker.wunderground.com");
        StringBuilder wholeBuffer = new StringBuilder();
        Expect expect = new ExpectBuilder()
                .withOutput(process.getOutputStream())
                .withInputs(process.getInputStream())
                .withEchoOutput(wholeBuffer)
                .withEchoInput(wholeBuffer)
                .withExceptionOnFailure()
                .build();

这是一个
