我正在尝试制作一个使用 AdWords API 的 Azure 函数。我正处于代码运行良好的地步，我所要做的就是让函数以给定的间隔运行。 但是，当我尝试在本地运行该函数时，我收到以下错误消息：
[22-Jun-18 19:08:58] Executed 'KeywordPlanner' (Failed, Id=ab7c3ecf-1238-4370-ab5b-17d547d354b3)
[22-Jun-18 19:08:58] System.Private.CoreLib: Exception while executing function: KeywordPlanner. System.Configuration.ConfigurationManager: Configuration system failed to initialize. System.Configuration.ConfigurationManager: Unrecognized configuration section system.serviceModel. (C:UsersfredeAppDataLocalAzure.Functions.V2.Clifunc.dll.config line 204)
如果我尝试上传函数并运行它，则会出现此错误：
2018-06-22T18:50:35 Welcome, you are now connected to log-streaming service.

我使用的是.NET Standard 2.0。
我该怎么做才能修复此错误并使我的函数运行？
更新：
在刘杰瑞的帮助下解决问题后，我收到以下错误：
2018-06-25T07:43:20.517 [Error] System.Private.CoreLib: Exception while executing function: KeywordPlanner. System.Net.Http.WinHttpHandler: WinHttpHandler is only supported on .NET Framework and .NET Core runtimes on Windows. It is not supported for Windows Store Applications (UWP) or Unix platforms.

更新
问题现在在这里跟踪。运行时文件夹[FunctionProject]binDebugnetcoreapp2.1binruntimes中的程序集不会加载到函数上下文中。
在@Adrian的帮助下，事实证明问题WinHttpHandler is only supported on .NET Framework and .NET Core runtimes on Windows从lib%USERPROFILE%.nugetpackagessystem.net.http.winhttphandler4.4.0libnetstandard2.0复制的错误程序集导致，而我们需要运行时汇编。
解决方法是将这些运行时程序集复制到bin文件夹，使其由函数宿主加载。安装Google.AdWords24.1.0 后，右键单击项目，Edit <FunctionProjectName>.csproj添加复制操作。使用 nuget 包的完整路径，我们不必先将程序集复制到项目中。
请注意，一旦我们安装了新版本的软件包，这些路径可能会更改。

Jerry 描述的相同解决方法适用于WinHttpHandler问题。我的 Azure Functions v2 项目文件中有以下内容：
<ItemGroup>
<None Update="System.Private.ServiceModel.dll">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</None>
<None Update="System.Net.Http.WinHttpHandler.dll">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</None>

<Target Name="CopySPSM" BeforeTargets="Build">
<Copy SourceFiles="System.Private.ServiceModel.dll" DestinationFolder="$(OutputPath)bin" />
<Copy SourceFiles="System.Net.Http.WinHttpHandler.dll" DestinationFolder="$(OutputPath)bin" />
</Target>
FWIW，仅当您尝试向 Google Ads API 发出服务请求时，才需要添加WinHttpHandler- 报告请求和响应在没有它的情况下工作正常。
