1. 运行 .sh 脚本

public static String run(String command) throws IOException {
            Scanner input = null;
            String result = "";
            Process process = null;
            try {
                process = Runtime.getRuntime().exec(command);
                try {
                    //等待命令执行完成
                    process.waitFor(10, TimeUnit.SECONDS);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                InputStream is = process.getInputStream();
                input = new Scanner(is);
                while (input.hasNextLine()) {
                    result += input.nextLine() + "\n";
                }
                result = command + "\n" + result; //加上命令本身，打印出来
            } finally {
                if (input != null) {
                    input.close();
                }
                if (process != null) {
                    process.destroy();
                }
            }
            return result;
        }

2. 运行curl 命令

public static String execCurl(String[] cmds) {
            ProcessBuilder process = new ProcessBuilder(cmds);
            Process p;
            try {
                p = process.start();
                BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
                StringBuilder builder = new StringBuilder();
                String line = null;
                while ((line = reader.readLine()) != null) {
                    builder.append(line);
                    builder.append(System.getProperty("line.separator"));
                }
                return builder.toString();
    
            } catch (IOException e) {
                System.out.print("error");
                e.printStackTrace();
            }
            return null;
    
        }

测试:

shell格式:

curl -u "admin:admin" -X POST -H "Content-Type: application/json"  "http://127.0.0.1:8088/api/users"

\-d '\{"password":"abc123\#","email":"123456789@qq.com","username":"postmanTest","realname":"postmanTest"\}'

@Override
        public String addUser(UserReqBO userReqBO) {
            String addUserUrl = harborUrl + "/api/users";
            JSONObject jsonObject = new JSONObject();
            jsonObject.put("username",userReqBO.getUserName());
            jsonObject.put("email",userReqBO.getEmail());
            jsonObject.put("realname",userReqBO.getRealName());
            jsonObject.put("password",userReqBO.getUserPassword());
            jsonObject.put("comment",null);//
    
            String jsonParams = jsonObject.toString();
            String command = "curl -u \""+adminName+":"+adminPwd+"\" -X POST -H \"Content-Type: application/json\" \""+addUserUrl
                    +"\" -d '"+jsonParams+"'";
            String admin=adminName+":"+adminPwd;
            String[] cmds={"curl","-u", admin,"-X", "POST","-H","Content-Type: application/json",addUserUrl,"-d",jsonParams};
            String result = null;
            try {
                result = HarborUtil.execCurl(cmds);
                System.out.println(result);
            } catch (Exception e) {
                e.printStackTrace();
            }
            return result;
        }
