c# - 在 Azure Functions 上使用 AdWords API

Question

我正在尝试创建一个使用 AdWords API 的 Azure 函数。我现在的代码工作正常，我所要做的就是让函数按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)

如果我尝试上传该函数并运行它，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)

我使用的是 .NET Standard 2.0。

我该如何修复此错误并让我的函数运行？

更新:

在 Jerry Liu 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

问题现在正在跟踪here 。运行时文件夹中的程序集[FunctionProject]\bin\Debug\netcoreapp2.1\bin\runtimes没有加载到函数上下文中。

在@Adrian的帮助下，发现了问题WinHttpHandler is only supported on .NET Framework and .NET Core runtimes on Windows从 lib %USERPROFILE%\.nuget\packages\system.net.http.winhttphandler\4.4.0\lib\netstandard2.0 复制错误的程序集导致的结果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文件夹以使其由函数主机加载。之后Google.AdWords 24.1.0已安装，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，这些路径可能会发生变化。
