访问WCF的ASP.Net类库项目

现有的Asp.Net项目正在使用WCF WebService。 工作正常。

我决定将业务逻辑移到类库中。所以现在Class库使用WCF Web服务,而Asp.net应用程序没有引用它。

在Asp.net网络应用程序第一次调用类库(调试)时出现错误:

  

找不到引用合约'CouponParking.ICouponService'的默认端点元素    在ServiceModel客户端配置部分中。     这可能是因为找不到您的应用程序的配置文件,    或者因为在客户端元素中找不到与此合同匹配的端点元素。

我已经盯着类库app.config(当我第一次向WCF服务添加服务引用时由IDE创建),它看起来还不错。

假设需要改变,有人可以对它进行批评,并告诉我需要做什么。我对终点的理解还不成熟。

asp.net web.config确实有一个空的servicemodel部分。我认为这是正确的,因为服务引用已被删除。

类库app.config接着是WCF web.config,因此您可以看到另一端。

WCF还有一个额外的JSON端点,因为它也被Android设备使用。

App.Config中:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="SoapEndPoint" />
        </basicHttpBinding>
    </bindings>
    <client>
        <endpoint address="http://localhost:8707/CouponParking.svc/SOAP"
            binding="basicHttpBinding" bindingConfiguration="SoapEndPoint"
            contract="CouponParking.ICouponService" name="SoapEndPoint" />
    </client>
</system.serviceModel>
</configuration>

类库使用其消费应用程序的配置文件 - 它们不使用自己的配置文件。因此,您需要将system.serviceModel部分从库的app.congif移动到ASP.NET应用程序的web.config:

<system.serviceModel>
  <bindings>
    <basicHttpBinding>
      <binding name="SoapEndPoint" />
    </basicHttpBinding>
  </bindings>
  <client>
    <endpoint address="http://localhost:8707/CouponParking.svc/SOAP"
              binding="basicHttpBinding" 
              bindingConfiguration="SoapEndPoint"
              contract="CouponParking.ICouponService" 
              name="SoapEndPoint" />
  </client>
</system.serviceModel>

现在,当您从ASP.NET应用程序调用类库时,它应该选择绑定和客户端端点。
