了解 AMF 轮询呼叫 [英] Understanding an AMF Polling call
问题描述
我的一位测试人员向我询问我们在应用中进行的 AMF 投票:
One of my testers is asking me about an AMF polling that we do in our app:
flex_amf_call(
"AMF3_call_12",
"Gateway=http://test.url.com:22000/InventoryTesting/boa/messagebroker/amfpolling",
"Snapshot=t19.inf",
MESSAGE,
"Method=null",
"TargetObjectId=/7",
BEGIN_ARGUMENTS,
"<AMF3><object-externalizable-custom><flex.messaging.messages.CommandMessage>\n "
"<destination>InvTestMessaging</destination>\n <messageId>"
"4AF91854-F89E-F56D-EE22-4EC8BBAEA4BC</messageId>\n <timestamp>0</timestamp>\n "
"<timeToLive>0</timeToLive>\n <headers>\n <entry>\n <string>"
"DSEndpoint</string>\n <string>my-polling-amf</string>\n </entry>\n "
"<entry>\n <string>DSId</string>\n <string>{ParamDSValue_string}"
"</string>\n </entry>\n </headers>\n <body serialization=\"custom\" class="
"\"flex.messaging.io.amf.ASObject\">\n <unserializable-parents/>\n <map>\n "
" <default>\n <loadFactor>0.75</loadFactor>\n <threshold>"
"12</threshold>\n </default>\n <int>16</int>\n <int>0</int>\n "
"</map>\n <flex.messaging.io.amf.ASObject>\n <default>\n "
"<inHashCode>false</inHashCode>\n <inToString>false</inToString>\n "
"</default>\n </flex.messaging.io.amf.ASObject>\n </body>\n <correlationId/>"
"\n <operation>0</operation>\n</flex.messaging.messages.CommandMessage>"
"</object-externalizable-custom></AMF3>",
END_ARGUMENTS,
LAST);
这个节点是什么意思?
<operation>
他们看到的值为 0 和 5.
They are seeing values of 0 and 5.
推荐答案
操作为 0 的 CommandMessage 是订阅"操作，在与服务器发起会话时自动发送在某些情况下.操作为 5 的 CommandMessage 是ping"操作，服务器必须以适当填充的 AcknowledgeMessage 进行响应，否则 AMF 通信将终止.CommandMessage 由 flash 播放器根据需要自动发送，您使用的任何服务器都应适当配置为自动处理它们，或为它们的处理提供钩子(如登录和注销操作).
A CommandMessage with an operation of 0 is a "subscribe" operation, and is sent automatically when a session is initiated with the server under certain circumstances. A CommandMessage with an operation of 5 is a "ping" operation, and the server must respond with an appropriately populated AcknowledgeMessage or AMF communication is terminated. A CommandMessage is automatically sent by the flash player as needed, and whatever server you're using should be appropriately configured to automatically handle them, or provide hooks for their handling (like with login and logout operations).
