这是授权时的url
http://www.douban.com/service/auth/authorize?
oauth_token=957cafde5a115a79c0760f9b0e340f6b&oauth_callback=http://localhost:8080/ART/user/doubanOAuth.action
这是授权后的跳转的url
http://localhost:8080/ART/user/doubanOAuth.php?oauth_token=957cafde5a115a79c0760f9b0e340f6b
通过用户授权后，通过response重定向到 doubanLogin.action
response.sendRedirect(myService.getAuthorizationUrl("http://localhost:8080/ART/user/doubanLogin.action"));
下面是doubanLogin.action 里面的代码
- Java code
String requestToken = request.getParameter("oauth_token"); DoubanService myService = new DoubanService("subApplication", apiKey, secret); if(requestToken != null) { myService=(DoubanService) request.getSession().getAttribute("DoubanService");// // step2 : user give the authorization and prepare to get the request token Cookie[] cookies = request.getCookies(); if (cookies == null) { System.err.println("request token secret not found in cookie"); return; } Cookie c = cookies[0];// // set request token and token secret myService.setRequestTokenSecret(c.getValue()); myService.setRequestToken(requestToken);// // get request token [color=#FF0000]myService.getAccessToken();[/color]在红色的这一步出现异常。（经过反复的测试，只要我用重定向的方式，就会出错，但是把授权时的url写在页面上的A标签里面，就能正确运行。） 下面是异常：
- Java code

我实在不能理解这2者有什么区别？ 有哪位大神搞过豆瓣的oauth 认证的求指导，万分感谢！
这是豆瓣API中提到的，没能完全理解： 然而进行POST、PUT、DELETE请求时，豆瓣暂时不支持使用在url中或者post form中传递OAuth参数。因此你只能选择在header中传递OAuth参数
------解决方案--------------------------------------------------------
com.google.gdata.util.AuthenticationException: Unauthorized
no auth
看样子应该是没有授权把，你的access_token是怎样取的？我只弄过oauth2。2的话，获取access_token需要传应用id和密钥和code参数还有回调地址。oauth1就不清楚了。是不是漏传了什么参数啊？
