java - 我可以使用 CURL -u 访问 XML 数据，并使用 HTTP Basic Auth 在浏览器中获取它。如何在 Java 中复制该过程？

Question

curl -u APIKEY https://api.recurly.com/v2/accounts

在终端中...像魅力一样工作并获得我想要的 XML...

更新：

https://companyName.recurly.com/v2/accounts.xml 要求输入用户名和密码以从浏览器窗口访问 xml。我可以输入这个，浏览器将为我显示 xml 数据。我只需要一个准系统来完成将 xml 文档带入我的“System.out.println()”屏幕的内容。我会从那里弄清楚我只需要在我的屏幕上获取数据！

Answer 1

你可以在你的java代码中使用HttpClient

见链接

Answer 2

我会使用 HttpURLConnection 来获取它

    URL url = new URL(fileURL);
    HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();

    System.out.println("Content-Type = " + httpConn.getContentType());
    System.out.println("Content-Disposition = " + httpConn.getHeaderField("Content-Disposition"));
    System.out.println("Content-Length = " + httpConn.getContentLength());

   InputStream inputStream = httpConn.getInputStream();

这是我一直在寻找的答案。我在这个网站上找到了它... http://www.avajava.com/tutorials/lessons/how-do-i-connect-to-a-url-using-basic-authentication.html。我很兴奋，我终于让它工作了。这就像一个魅力，只需用您的信息替换“companyName”和“APIKEY”。感谢大家以及他们的投入和帮助！
