以下两种情况之间的区别是什么:
配置1:
<service name="WcfService1.Service1" behaviorConfiguration="MyServiceTypeBehaviors">
<host>
<baseAddresses>
<add baseAddress="net.tcp://127.0.0.1:808/" />
</baseAddresses>
</host>
<endpoint address="service"
binding="netTcpBinding"
bindingConfiguration="MainBinding"
bindingName="MainBinding"
name="DefaultEndpoint"
contract="WcfService1.IService1" />
<endpoint address="mex"
binding="mexTcpBinding"
contract="IMetadataExchange" />
</service>
配置2:
<service name="WcfService1.Service1" behaviorConfiguration="MyServiceTypeBehaviors">
<host>
<baseAddresses>
<add baseAddress="net.tcp://127.0.0.1:808/service" />
</baseAddresses>
</host>
<endpoint address="net.tcp://127.0.0.1:808/service"
binding="netTcpBinding"
bindingConfiguration="MainBinding"
bindingName="MainBinding"
name="DefaultEndpoint"
contract="WcfService1.IService1" />
<endpoint address="mex"
binding="mexTcpBinding"
contract="IMetadataExchange" />
</service>
我的理解是在任何一种情况下基地址+端点地址解析为相同的绝对地址
但为什么我在配置2 上收到错误:“没有终点正在监听net.tcp://127.0.0.1:808 /
但配置1 运行服务时没有任何错误 !!!
修改1:
工作配置:
<host>
<baseAddresses>
<add baseAddress="net.tcp://127.0.0.1:808/" />
</baseAddresses>
</host>
<endpoint address="service"
binding="netTcpBinding"
bindingConfiguration="MainBinding"
bindingName="MainBinding"
name="DefaultEndpoint"
contract="WcfService1.IService1" />
非工作配置:
<host>
<!--
<baseAddresses>
<add baseAddress="" />
</baseAddresses>
-->
</host>
<endpoint address="net.tcp://127.0.0.1:808/service"
binding="netTcpBinding"
bindingConfiguration="MainBinding"
bindingName="MainBinding"
name="DefaultEndpoint"
contract="WcfService1.IService1" />
<endpoint address="mex"
binding="mexTcpBinding"
contract="IMetadataExchange" />
在这种情况下,我删除了基址并提供了完整的服务地址(带有.svc路径),但是出现套接字超时错误。这种情况怎么了?当没有定义基址时,端点地址是否始终需要.svc的完整地址?如果是这样,背后的原因可能是什么?
答案 0 :(得分:15)
baseAddress
就是你的端点的基地址(除非明确指定)。因此,每个<endpoint>
都会继承<baseAddress>
(这就是为什么它们通常为""
和"mex"
)。 e.g。
<baseAddresses>
<add baseAddress="http://127.0.0.1:1337/" />
</baseaddresses>
...
<endpoint address="" contract="MyService.IMyContract" ... />
<endpoint address="mex" contract="IMetadataExchange" ... />
您现在有两个端点:
http://127.0.0.1:1337/
- 服务端点http://127.0.0.1:1337/mex
- 元数据端点通过免除<baseAddress>
你要求<endpoints>
都是完全合格的(包括mex(不是))。 e.g。
<baseAddresses></baseaddresses>
...
<endpoint address="net.tcp://127.0.0.1:1337/" contract="MyService.IMyContract" ... />
<endpoint address="http://127.0.0.1:1337/mex" contract="IMetadataExchange" ... />
您现在有两个不同的端点:
net.tcp://127.0.0.1:1337/
- 服务端点http://127.0.0.1:1337/mex
- 元数据端点
