Java运行时出现问题

帮帮我,我是Java新手,目前正在做一个学校项目,需要我使用运行时来使用netsh查找WLAN ssid和mac地址。但是,控制台一直在向我提供此信息(Microsoft Windows [版本10.0.17134.165](c)2018 Microsoft Corporation。保留所有权利。)如何使它显示netsh命令输出代替

public static void main(String args[]) {

}

public void getWLANbssidInfo() {
    String netsh = "netsh wlan show networks mode = bssid";

    try {
        Process p1;
        p1 = Runtime.getRuntime().exec("cmd /c " + netsh);
        p1.waitFor();
        BufferedReader reader = new BufferedReader(new InputStreamReader(p1.getInputStream()));
        String line = reader.readLine();
        while(line!=null){
            System.out.println(line);
            line = reader.readLine();
        }
    } catch (IOException ex) {
        System.out.println("There was an IO exception.");
    } catch (InterruptedException ex) {
        System.out.println("The command was interrupted.");
    }
}

}

您必须使用接受axios({ method: 'delete', url: '***/api/steps', headers: { 'Content-type': 'application/x-www-form-urlencoded' }, params: { id: step.id } }).then(response => { this.getProjectSteps() this.getProjectDetail() }) 的{​​{1}}重载来指定命令和命令参数,例如:

请注意,如果可执行文件包含在运行命令的环境路径或工作目录(可以设置)中,则也可以不使用cmd命令运行exec()命令:

String[]

答案 1 :(得分:1)

您必须将参数作为单独的单词传递给exec()

这是一种方法:

p1 = Runtime.getRuntime().exec(("cmd /c " + netsh).split("\\s+"));
