使用Dropbox Java API将文件上载到Dropbox
我想使用Java API for DropBox上传文件。 以下代码为我提供了oauth_token和oauth_secret。 但是当我尝试上传文件时，我得到一个例外。
Java Class
package com.dropbox.client; import com.dropbox.client.DropboxAPI.Config; import java.io.File; import java.net.URL; import java.util.HashMap; import java.util.Map; /** * * @author Charan */ public class DBmain { public DBmain() { 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"); configuration.put("authorization_url", "http://api.dropbox.com/0/oauth/authorize"); configuration.put("port",80); //configuration.put("trusted_access_token_url","http://api.getdropbox.com/0/token"); configuration.put("server","api.getdropbox.com"); configuration.put("content_server","api-content.dropbox.com"); String username="myMailAddress@domain.com"; String password="myPassword"; try { Authenticator auth = new Authenticator(configuration); 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); //api.accountInfo(); //even this method gives me a exception } catch (Exception e) { e.printStackTrace(); } } public static void main(String[] args) { new DBmain(); } }
Exception

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，我不再获得上述exception[ java.lang.NoSuchMethodError ]此stackoverflow问题帮我解决了这个问题： java.lang.NoSuchMethodError：org.apache.http.protocol.BasicHttpContext：method （）V not found
但是现在我在执行API的任何方法时都会收到UnknownhostException

你应该使用http-client 4.0.3 jar
您的类不应该在com.dropbox.client包中。 尝试将其移动到另一个（即com.yourname.client ）。 看起来您可能正在创建名称冲突并无意中覆盖了Dropbox客户端API中的某些内容。
您已指定api.getdropbox.com:80作为主机名。 请尝试使用api.getdropbox.com 。
