推荐答案

如果您从服务提供商（例如Facebook，Twitter）调用RESTful服务，您可以这样做使用您选择的任何 flavor ：

If you are calling a RESTful service from a Service Provider (e.g Facebook, Twitter), you can do it with any flavour of your choice:

如果您不想使用外部库，可以使用 java .net.HttpURLConnection 或 javax.net.ssl.HttpsURLConnection （对于SSL），但这是在<$中的工厂类型模式中封装的调用C $ C> java.net.URLConnection中。
要接收结果，您必须 connection.getInputStream（），它会返回 InputStream 。然后，您必须将输入流转换为字符串并将字符串解析为其代表对象（例如XML，JSON等）。

If you don't want to use external libraries, you can use java.net.HttpURLConnection or javax.net.ssl.HttpsURLConnection (for SSL), but that is call encapsulated in a Factory type pattern in java.net.URLConnection. To receive the result, you will have to connection.getInputStream() which returns you an InputStream. You will then have to convert your input stream to string and parse the string into it's representative object (e.g. XML, JSON, etc).

或者， Apache HttpClient （版本4是最新的）。它比java的默认 URLConnection 更稳定和健壮，它支持大多数（如果不是全部）HTTP协议（以及它可以设置为严格模式）。您的回复仍然在 InputStream 中，您可以按上述方式使用它。

Alternatively, Apache HttpClient (version 4 is the latest). It's more stable and robust than java's default URLConnection and it supports most (if not all) HTTP protocol (as well as it can be set to Strict mode). Your response will still be in InputStream and you can use it as mentioned above.
