如何在执行之前获取processbuilder命令

Question

我想知道在它发生之前将执行的命令。

      String cmd[] = {"curl",
            "-X",
            "POST",
            "https://api.renam.cl/medicion/insert?access-token={Yoq3UGQqDKP4D1L3Y6xIYp-Lb6fyvavpF3Lm-8cD}",
            "-H",
            "content-type: application/json",
            "-d",
            json.toString()};

        ProcessBuilder pb = new ProcessBuilder(cmd);

        Log.debug("COMANDO.TOSTRING " + pb.command().toString());

        Process p = pb.start();

        Log.debug(p.getOutputStream().toString());

        p.waitFor();

        BufferedReader reader
                = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String readline;

        while ((readline = reader.readLine()) != null) {
            Log.debug(readline);
        }

使用readline我有服务器的答案输出，但我不知道热得到我已经与processbuilder一起完成的curl命令。

编辑1：

我只需要使用linux控制台发送此命令：

curl -X POST'https://api.com/data/insert?access-token=Yoq3UGQqDKP4D1L3Y6xIYp-Lb6fyvavpF3Lm-8cD'-H'content-type：application / json'-d'{“pm25”：2，“timestamp”：1495077872，“dispositivo_mac”：“12：34：56：78：90：12 “}'

基本上我需要打印由ProcessBuilder对象处理的cmd数组，以便在执行星形方法之前查看它。

这是打印runnable命令的代码：

private String getRunnableCommand(ProcessBuilder processBuilder)
{
    val commandsList = processBuilder.command();
    val runnableCommandBuilder = new StringBuilder();
    var commandIndex = 0;
    for (val command : commandsList)
    {
        if (command.contains(" "))
        {
            runnableCommandBuilder.append("\"");
        }
        runnableCommandBuilder.append(command);

        if (command.contains(" "))
        {
            runnableCommandBuilder.append("\"");
        }

        if (commandIndex != commandsList.size() - 1)
        {
            runnableCommandBuilder.append(" ");
        }

        commandIndex++;
    }
    return runnableCommandBuilder.toString();
}

var和val来自Lombok使用以下maven依赖：

    <version>LATEST</version>
    <scope>provided</scope>
