【问题描述】:
我有一个 wcf 自托管服务,旨在供计算机和 Android 手机使用。我成功地使服务在两个目标中都可以使用,但是当我构建一个 exe 文件(负责自托管服务)时,该服务在 pc 中运行良好,但在移动应用程序上却无法运行。 这是我的服务的 app.config 文件:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" />
</system.web>
<!-- When deploying the service library project, the content of the config file must be added to the host's
app.config file. System.Configuration does not support config files for libraries. -->
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="httpBinding" maxBufferSize="128000000" maxReceivedMessageSize="128000000" />
</basicHttpBinding>
<webHttpBinding>
<binding name="webBinding" closeTimeout="00:02:00" sendTimeout="00:02:00"
maxBufferSize="6553600" maxReceivedMessageSize="6553600" crossDomainScriptAccessEnabled="true" />
</webHttpBinding>
</bindings>
<diagnostics performanceCounters="Default" />
<services>
<service name="DeltaService.Data">
<endpoint address="data" binding="basicHttpBinding" bindingConfiguration="httpBinding"
name="data" contract="DeltaService.IData">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="json" behaviorConfiguration="Rest" binding="webHttpBinding"
bindingConfiguration="webBinding" name="restdata" contract="DeltaService.IData">

<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/delta_api/" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<endpointBehaviors>

</behavior>

<behavior name="">

<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment
aspNetCompatibilityEnabled="true"
multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
<parameters>
<parameter value="mssqllocaldb" />
</parameters>
</defaultConnectionFactory>
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
</configuration>
这是启动服务的代码:
serviceHost = new ServiceHost(typeof(Data));
NetHttpBinding netHttpBinding = new NetHttpBinding();
netHttpBinding.MaxReceivedMessageSize = 128 * 1000000; //128Mb
serviceHost.AddServiceEndpoint(typeof(IData), netHttpBinding, url);
erviceHost.Open();
【问题讨论】:
-
您的移动设备和服务器之间的 HTTP 活动是什么样的?
-
同一网络上的其他电脑可以访问该服务吗?移动设备如何连接到电脑(或同一个网络)?您的网络是什么样的?
-
可以,同一网络的其他电脑可以访问该服务,移动设备也连接到同一网络。 android 应用程序向服务发送 HTTP Json 请求并获得 JSON 响应。
-
在 Visual Studio 上按运行时服务正常,但是当我构建 exe 文件时,它不起作用,所以问题出在 app.config 文件或 self-托管应用程序。
