机器码中的CPU、硬盘获取有问题

[starshift3]

存在问题： 部分系统Process读到的数据会出现空行，按行数截取获取不到硬件id信息 原方法：

public static String runCmd(String cmd, int line) {
        Process process;
        Scanner sc = null;
        StringBuffer sb = new StringBuffer();
        try {
            process = Runtime.getRuntime().exec(cmd);
            process.getOutputStream().close();
            sc = new Scanner(process.getInputStream());
            int i = 0;
            while (sc.hasNextLine()) {
                i++;
                String str = sc.nextLine();
                if (line <= 0) {
                    sb.append(str).append("\r\n");
                } else if (i == line) {
                    return str.trim();
                }
            }
            sc.close();
        } catch (Exception e) {


        } finally {
            close(sc);
        }
        return sb.toString();
    }

本地测试结果如下： macList:[C8-B2-9B-DA-42-B0, 00-50-56-C0-00-08] c1:00aabdc6d979de09f33e0751a5bf93df cpu: c2:d41d8cd98f00b204e9800998ecf8427e harddisk: c3:d41d8cd98f00b204e9800998ecf8427e code:00AABDC6D979DE09F33E0751A5BF93DFD41D8CD98F00B204E9800998ECF8427ED41D8CD98F00B204E9800998ECF8427E

尝试修改跳过空行：

public static String runCmd(String cmd, int line) {
        Process process;
        Scanner sc = null;
        StringBuffer sb = new StringBuffer();
        try {
            process = Runtime.getRuntime().exec(cmd);
            process.getOutputStream().close();
            sc = new Scanner(process.getInputStream());
            int i = 0;
            while (sc.hasNextLine()) {
                String str = sc.nextLine();
                if (str.isEmpty()) {
                    continue;
                }
                i++;
                if (line <= 0) {
                    sb.append(str).append("\r\n");
                } else if (i == line) {
                    return str.trim();
                }
            }
            sc.close();
        } catch (Exception e) {


        } finally {
            close(sc);
        }
        return sb.toString();
    }

修复后结果如下： macList:[C8-B2-9B-DA-42-B0, 00-50-56-C0-00-08] c1:00aabdc6d979de09f33e0751a5bf93df cpu:178BFBFF00860F01 c2:896dc7fffc815496d9e132ac82f5c7dc harddisk:0025_3885_01B0_F990. c3:60862dccd033fb4ae4fb0337c60525c4 code:00AABDC6D979DE09F33E0751A5BF93DF896DC7FFFC815496D9E132AC82F5C7DC60862DCCD033FB4AE4FB0337C60525C4
