  是的，你必须创建一个Facebook应用程序，以便让你的网站用户在Facebook上发布他们的东西 .

  使用OAuth 2.0的身份验证过程非常简单：

  • 来电 https://graph.facebook.com/oauth/authorizeclient_id=<your app's client_id>&redirect_uri=<your redirect URU> . 如您所见，您必须传输您的client_id和一个URI，Facebook将在流程结束时重定向 . 您还可以传输数据参数，该参数将在整个过程中保持不变 . 用于跟踪用户 .

  • call https://graph.facebook.com/oauth/access_token?client_id=<your app's client_id>&redirect_uri=h<your redirect URU>&client_secret=<your app's client_secret>&code=<code> 代码参数由上一步调用重定向URI给出

  • 调用 https://graph.facebook.com/me?access_token=<access_token> ，使用前一个重定向返回的ad-hoc access_token，然后得到真正的 access_token .

  您需要从opengraph explorer找出您的用户ID和访问令牌

  以下Java代码（使用apache http client）在facebook墙上发布指定用户标识的消息 .

  public class Main2 {
  
      public static void main(String[] args) {
  
  
  
          HttpClient httpclient = new DefaultHttpClient();
  
          try {
  
  
              String accessToken = "AAACEdEose0cBANzDaBq";
  
              String message = "Hey Jude, don't make it bad";
  
              String userId = "200501511023";
  
              String requestURL = "https://graph.facebook.com/"+userId+"/feed";
  
              HttpPost httpPost = new HttpPost( requestURL );
  
              List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
              nameValuePairs.add(new BasicNameValuePair("access_token", accessToken));
              nameValuePairs.add(new BasicNameValuePair("message", message));
  
  
              httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
  
  
              // Create a response handler
              ResponseHandler<String> rh = new ResponseHandler<String>() {
  
                  public String handleResponse(HttpResponse hr) throws ClientProtocolException, IOException {
                      return "\n" + hr.getStatusLine() + "\n\n"
                          + dumpStream(hr.getEntity().getContent());
                  }
              };
  
              System.out.println("****************************************");
              System.out.println("executing request " + httpPost.getURI());
              System.out.println("****************************************");
  
              String response = httpclient.execute(httpPost, rh);
  
  
              System.out.println("----------------------------------------");
              System.out.println(response);
              System.out.println("----------------------------------------");
  
  
          } catch (IOException e) {
              e.printStackTrace();
          }
      }
  
       public static String dumpStream(InputStream is) {
      try {
  
          byte[] theBytes = new byte[is.available()];
          is.read(theBytes, 0, is.available());
          is.close();
          return new String(theBytes);
      } catch (IOException ex) {
      }
      return null;
  } // ()
  }  // class
