开放平台和Oauth认证
| 开放平台 豆瓣网站 社交开放式平台 新浪微博 人人网 豆瓣API是豆瓣为第三方开发人员提供的编程接口。 利用豆瓣API，你可以在你的网站或程序中使用豆瓣的数据和功能 |
| Oauth认证由来 如在京东网使用qq登录，在使用qq登录时，会跳转到qq.com进行登录，然后登录成功，会将数据又发给京东，进行认证成功。 解决的问题： 相互信任的问题 |
| Oauth认证过程 |
| Oauth认证代码： public static boolean Login(String name, String pwd, String captchaValue,
String captchaId, Context context) throws Exception {
