Java中的curl命令

Question

首先，我已经看过几个文档，关于同一文档的stackoverflow问题。我在尝试运行命令时遇到了项目特定的问题：

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

从mac终端，我得到了所需的json格式数据。但是从Java代码运行相同的命令，控制台中出现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();
        }

我收到未经授权的401错误和一堆html标签。这似乎是一个重复性的问题，但我已经尝试了所有方法。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};

进入

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