System.setProperty("java.net.useSystemProxies", "true");
Map configuration= new HashMap();
configuration.put("consumer_key", "XXXXXXXXXXXXXXXX");
configuration.put("consumer_secret", "XXXXXXXXXXXXXXXX");
configuration.put("request_token_url", "http://api.dropbox.com/0/oauth/request_token");
configuration.put("access_token_url", "http://api.dropbox.com/0/oauth/access_token");

String url = auth.retrieveRequestToken("");
String access_key = auth.getTokenKey();
String access_secret = auth.getTokenSecret();
System.out.println(access_key);
System.out.println(access_secret);
DropboxAPI api = new DropboxAPI();
DropboxAPI.Config conf = api.new Config(configuration);
api.authenticateToken("XXXXXXXXXXXX", "XXXXXXXXXXX", conf);
System.out.println(api.isAuthenticated());
URL resource = this.getClass().getResource("/config/testing.json");
File f= new File(resource.toURI());
api.putFile("dropbox", "/Project", f);

一些额外的信息
我将 httpclient-4.0-beta1.jar 和 httpcore-4.0-alpha6.jar 分别更改为 httpclient-4.0.jar 和 httpcore-4.0.1.jar,我不再得到上述异常 [ java.lang.NoSuchMethodError ]
这个stackoverflow问题帮助我解决了这个问题:java.lang.NoSuchMethodError: org.apache.http.protocol.BasicHttpContext: 方法 <init>()V 未找到
I changed the httpclient-4.0-beta1.jar and httpcore-4.0-alpha6.jar to httpclient-4.0.jar and httpcore-4.0.1.jar respectively and I no longer get the above exception [ java.lang.NoSuchMethodError ]
This stackoverflow question helped me in solving this : java.lang.NoSuchMethodError: org.apache.http.protocol.BasicHttpContext: method <init>()V not found
但现在我在执行 API 的任何方法时都会收到 UnknownhostException
But Now I get UnknownhostException on execution of any methods of the API
