在 Azure Functions 上使用 AdWords API

Question

我正在尝试制作一个使用 AdWords API 的 Azure 函数。我的代码工作正常，我所要做的就是让函数以给定的时间间隔运行。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:\Users\frede\AppData\Local\Azure.Functions.V2.Cli\func.dll.config line 204)如果我尝试上传函数并运行它，我会收到此错误：2018-06-22T18:50:35  Welcome, you are now connected to log-streaming service.2018-06-22T18:50:40.967 [Information] Executing 'KeywordPlanner' (Reason='This function was programmatically called via the host APIs.', Id=321756f7-3cf1-4235-a741-daf97d304058)2018-06-22T18:50:40.972 [Error] System.Private.CoreLib: Exception while executing function: KeywordPlanner.

Answer 1

问题现在在这里跟踪。运行时文件夹[FunctionProject]\bin\Debug\netcoreapp2.1\bin\runtimes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是由于%USERPROFILE%\.nuget\packages\system.net.http.winhttphandler\4.4.0\lib\netstandard2.0在我们需要运行时程序集时从 lib 复制的错误程序集所致。

解决方法是将这些运行时程序集复制到bin文件夹以使其由函数宿主加载。后Google.AdWords安装24.1.0，右键单击项目，Edit <FunctionProjectName>.csproj添加复制操作。有了 nuget 包的完整路径，我们不必先将程序集复制到我们的项目中。

请注意，一旦我们安装了新版本的软件包，这些路径可能会改变。

Answer 2

Jerry 描述的相同解决方法将适用于该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>

</ItemGroup>

<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，WinHttpHandler似乎只有在您尝试向 Google Ads API 发出服务请求时才需要添加 - 报告请求和响应没有它就可以正常工作。
