java中的curl命令

Question

首先,我已经看过几个文件,有关相同的stackoverflow问题..我的项目特定问题在尝试运行命令时:

   curl -u username:password https://example.com/xyz/abc 

从mac终端,我得到了我想要的json格式数据.但是从java代码运行相同的命令,我在控制台中收到Unauthorized 401错误.我的代码是:

    String username="myusername";
    String password="mypassword";
    String url="https://www.example.com/xyz/abc";
       String[] command = {"curl", "-u" ,"Accept:application/json", username, ":" , password , url};
        ProcessBuilder process = new ProcessBuilder(command); 
        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"));
                }
                String result = builder.toString();
                System.out.print(result);

        }
        catch (IOException e)
        {   System.out.print("error");
            e.printStackTrace();
        }

我收到了未经授权的401错误和一堆html标签.这似乎是一个重复的问题,但我已经尝试了所有的方法.我知道替代方法是使用http响应方法,但特别是我想使用curl命令.提前致谢.

尝试更改此行

String[] command = {"curl", "-u" ,"Accept:application/json", username, ":" , password , url};

成

String[] command = {"curl", "-H", "Accept:application/json", "-u", username+":"+password , url};
