如何在执行前获取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 我有服务器答案输出，但我不知道如何获取我用 processbuilder 执行的 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 ProcessBuilder 对象处理的 cmd 数组，以便在 star 方法执行之前查看它。

以下是打印可运行命令的代码：

private String getRunnableCommand(ProcessBuilder processBuilder)
{
    List<String> commandsList = processBuilder.command();
    StringBuilder runnableCommandBuilder = new StringBuilder();
    int commandIndex = 0;
    for (String 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();
}

它将用引号将包含空格的参数正确括起来。
