381.5. 消耗消息

Yammer 组件为消耗消息提供了多个端点：

URI描述
 yammer:messages?[options]

用户的所有公共消息（其访问令牌用于进行 API 调用）Yammer 网络。对应于 Yammer Web 界面中的"所有"对话。 

 yammer:my_feed?[options]

用户反馈，根据他们在"Following"和"回复"对话之间作出的选择。 

yammer:algo?[options]

与"Top"对话对应的用户的算法源，这是大多数用户在 Yammer Web 界面中看到的内容。 

yammer:following?[options]

"后续"反馈，是涉及用户所遵循的人员、组和主题的对话。 

yammer:sent?[options]

用户发送的所有消息。 

yammer:private?[options]

用户接收的专用消息。 

yammer:received?[options]

Camel 2.12.1： 用户接收的所有消息

381.5.1. 消息格式

默认情况下，所有消息都会转换为 org.apache.camel.component.yammer.model 包中提供的 POJO 模型。来自 yammer 的原始消息采用 JSON。对于消耗和生成端点的所有消息，将返回 Messages 对象。使用类似以下的路由示例： 

from("yammer:messages?consumerKey=aConsumerKey&consumerSecret=aConsumerSecretKey&accessToken=aAccessToken")
    .to("mock:result");

和 lets 表示 yammer 服务器返回：

    "messages":[
        {
            "replied_to_id":null,
            "network_id":7654,

                "plain":"(Principal Software Engineer) has #joined the redhat.com network. Take a moment to welcome Jonathan.",
                "rich":"(Principal Software Engineer) has #joined the redhat.com network. Take a moment to welcome Jonathan."
            },

                "names":[

                ]

            }
        }
        ]

    }

Camel 将摘要到包含 2 消息 对象的 Messages 对象中。如下所示，有一个丰富的对象模型，可轻松获得您需要的信息： 

Exchange exchange = mock.getExchanges().get(0);
Messages messages = exchange.getIn().getBody(Messages.class);

assertEquals(2, messages.getMessages().size());
assertEquals("Testing yammer API...", messages.getMessages().get(0).getBody().getPlain());
assertEquals("(Principal Software Engineer) has #joined the redhat.com network. Take a moment to welcome Jonathan.", messages.getMessages().get(1).getBody().getPlain());

具体说，通过向您的 URI 添加 使用Json=false 选项，则将此数据进行汇总为 POJO 不可行。
