带有utf-8字符的Runtime.exec()命令 [英] Runtime.exec() command with utf-8 characters

问题描述

我正在尝试执行包含波兰语字符的Runtime.getRuntime().exec()命令.命令从第一个波兰字母中切出.我得到的不是波兰字母，而是?".

I'm trying to execute Runtime.getRuntime().exec() command which contains polish characters. Command is cutted from the first polish letter. Instead of polish letter i'm getting "?".

如何设置正确的编码以正确执行此命令?

How can I set correct encoding to exec this command properly?

我正在使用的命令:execCommand("php/home/script/url param1 param2 param3)

Command which i'm using : execCommand("php /home/script/url param1 param2 param3)

execCommand看起来像:

execCommand looks like :

private String execCommand(String command)
{
    String output="";
    try
    {
        Process proc = Runtime.getRuntime().exec(command);
        BufferedReader read = new BufferedReader(new InputStreamReader(proc.getInputStream()));
        try
        {
        proc.waitFor();
        }
        catch(InterruptedException e) 
        {
            output=e.getMessage();
        }
        while(read.ready())
        {
            output=read.readLine();
        }
    }
    catch(IOException e)
    {
        output=e.getMessage();
    }

    return output;
}

推荐答案

您可以尝试以下操作:

String command = URLEncoder.encode("<your command>", "utf-8");

然后您可以尝试通过 Runtime.exec

您还可以检查您的JDK是否真正支持:

You could also check if your JDK actually supported:

Charset.forName("UTF-8")

如果由于某种原因失败，则说明您的JDK中可能存在错误/未配置

If this fails for any reasons then there's probably something wrong/not configured in your JDK
