JOAuth，一个基于java的OAuth 1（最终版）和OAuth 2（草案10）库。我如何使用它？

我在这里看到了太多关于OAuth的问题，以及如何使用OAuth协议连接到Facebook Graph API或Twitter API

我已经发现了（从谷歌代码），我想知道如何使用它？JOAuth还提供了哪些其他功能？它与其他java oauth库配合得好吗？

鉴于我已经编写了JOAuth，我认为应该这样回答这个问题。我找不到将此问题设置为社区wiki的选项：(

注意我不是来讨论的。有很多专门的网站

JOAuth有一个很棒的特性，它有一个控制器

OAuthServlet

，用于管理来自服务提供商的HTTP重定向响应。 要将

OAuthServlet

配置到web应用程序，只需在

web.xml

中将其声明为

，如下所示：

 <servlet>
  <description>An OAuth Servlet Controller</description>
  <display-name>OAuthServlet</display-name>
  <servlet-name>OAuthServlet</servlet-name>
  <servlet-class>com.neurologic.oauth.servlet.OAuthServlet</servlet-class>
  <init-param>
   <param-name>config</param-name>
   <param-value>/WEB-INF/oauth-config.xml</param-value>
  </init-param>
  <load-on-startup>3</load-on-startup>
 </servlet>

您会注意到，每个

元素都有一个

版本

属性（这是控制器需要知道要使用哪个oauth流的强制属性）。这些只有有两个可能的值（OAuth1的

1

和OAuth2的

2

）。 对于OAuth 2，

元素不像版本1中的对应元素那样具有

requestTokenUrl

属性

OAuth服务是负责OAuth处理的服务。控制器通过

execute（）

方法调用每个

OAuthService

。 有两种类型的

OAuthService

：

• com.neurologic.oauth.service.impl.OAuth1Service

• com.neurologic.oauth.service.impl.OAuth2Service

注意对于每个服务，如果您使用的是OAuth 2，必须有一个扩展了

OAuth2Service

的服务。这同样适用于OAuth 1。否则将引发异常

每个

标记必须具有

名称

属性，该属性与

名称属性匹配（区分大小写）

已实现

OAuth1Service

和

OAuth2Service

execute（HttpServletRequest，HttpServletResponse）

以最好地处理OAuth授权协议的流，但如果不满意，可以覆盖它
