问题

我正在尝试创建一个利用 .NET Core 2.2 的 Azure 函数，该函数通过 Google Sheets API 访问 Google Sheet，调用数据，并将其插入同样托管在 Azure 中的 SQL DB。

这是我的错误：

这是在遵循this 指南之后。

请注意，所有包都已恢复。

代码大致如下：

#r "D:\home\site\wwwroot\bin\Google.Apis.Sheets.v4"
#r "D:\home\site\wwwroot\bin\Google.Apis.Auth.OAuth2"
#r "D:\home\site\wwwroot\bin\Google.Apis.Sheets.v4"
#r "D:\home\site\wwwroot\bin\Google.Apis.Sheets.v4.Data"
#r "D:\home\site\wwwroot\bin\Google.Apis.Services"
#r "D:\home\site\wwwroot\bin\System.Data.SqlClient"

using System;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Sheets.v4;
using Google.Apis.Sheets.v4.Data;
using Google.Apis.Services;
using System;
using System.Collections.Generic;
using System.IO;
using System.Data.SqlClient;


public static string DBConn { get; set; }
public static ILogger Log {get; set;}
public static void Run(TimerInfo myTimer, ILogger log)
{   
    Log=log;  
    DBConn="MySQLSrvrConnectionString";
    try
    {
        string spreadsheetId = "MyGoogleSheetId";
        SheetsService service = GetSheetService();
        if(service!=null)
        {
            DoSomethingFunc(GetInsertCommand(GetSheetVals(service,spreadsheetId)));
        }
    }
    catch (Exception ex)
    {
        Log.LogInformation($"Error ({DateTime.Now.ToLongDateString()}): {ex.Message}");
    }
    finally
    {
        Log.LogInformation($"Function Completed at: {DateTime.Now.ToLongDateString()}");
    }
}

如果需要，我可以提供更多。

我还添加了一个 function.proj 文件：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Google.Apis.Sheets.v4" Version="1.40.3.1679" />
    <PackageReference Include="System.Data.SqlClient" Version="4.6.1" />
  </ItemGroup>

</Project>

研究 老实说，没有找到太多。

• This 是一个类似的错误代码，但它似乎是一个命名问题 - 有一个撇号。我的应用名为“TopicsProvider”
• This 谈论 Webparts XML 文件。这根本不是我项目的一部分。

更新 1

将代码还原为最简单的形式，我可以让它与 function.proj 中引用的 Google API 一起运行。此代码有效：

using System;
using System.Collections.Generic;
using System.IO;
using System.Data.SqlClient;
public static void Run(TimerInfo myTimer, ILogger log)
{
    log.LogInformation($"HELLO");
}

使用这样的function.proj：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Google.Apis.Sheets.v4" Version="1.40.3.1679" />
  </ItemGroup>

</Project>

失败的是在顶部添加using Google.Apis.Sheets.v4;。这给出了：

error CS0246: The type or namespace name 'Google' could not be found (are you missing a using directive or an assembly reference?)

在顶部添加#r "Google.Apis.Sheets.v4" 或D:\home\site\wwwroot\bin\Google.Apis.Sheets.v4"（请注意，在控制台中，没有以bin 文件夹开头...不确定原因），并不能解决问题，并更改错误：

脚本编译失败。

The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

据我了解，#r 不是必需的，不是根据this 的答案。包应自行加载。我也不应该上传这些文件 - 它们是应该自动安装的 nuget 包。

更新 2

手动上传 DLL 不起作用。从“上传”中选择文件，有一段时间界面就像正在加载一样，但是什么也没发生：

我错过了什么？是否不允许使用其中一个包？是配置问题吗？

Answer 1

更新：

我重试你所做的，然后它似乎成功了，

1.创建function.proj文件

2.保存文件并运行：

 <Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Google.Apis.Sheets.v4" Version="1.40.3.1679" />
    <PackageReference Include="System.Data.SqlClient" Version="4.6.1" />
  </ItemGroup>
</Project>

3.在.crx文件中添加代码：

#r "Newtonsoft.Json"

using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;

public static string DBConn = "123456";
public static ILogger Log = null;

public static async Task<IActionResult> Run(HttpRequest req, ILogger log)
{
    Log=log;  
    DBConn="MySQLSrvrConnectionString";
    try
    {
        string spreadsheetId = "MyGoogleSheetId";
        //SheetsService service = GetSheetService();
        //if(service!=null)
        //{
        //    DoSomethingFunc(GetInsertCommand(GetSheetVals(service,spreadsheetId)));
        //}
    }
    catch (Exception ex)
    {
        Log.LogInformation($"Error ({DateTime.Now.ToLongDateString()}): {ex.Message}");
    }
    finally
    {
        Log.LogInformation($"Function Completed at: {DateTime.Now.ToLongDateString()}");
    }
    string name = req.Query["name"];

    string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
    dynamic data = JsonConvert.DeserializeObject(requestBody);
    name = name ?? data?.name;

    return name != null
        ? (ActionResult)new OkObjectResult($"Hello, {name}")
        : new BadRequestObjectResult("Please pass a name on the query string or in the request body");
}

4.然后编译成功：

PS：google .net 客户端库没有名为 get sheet service 的方法。

原答案：

这是我的代码：

public static class Function1
{
    public static string DBConn { get; set; }
    public static ILogger Log { get; set; }
    [FunctionName("Function1")]
    public static async Task<IActionResult> Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
        ILogger log)
    {
        Log = log;
        DBConn = "MySQLSrvrConnectionString";
        try
        {
            string spreadsheetId = "MyGoogleSheetId";

        }
        catch (Exception ex)
        {
            Log.LogInformation($"Error ({DateTime.Now.ToLongDateString()}): {ex.Message}");
        }
        finally
        {
            Log.LogInformation($"Function Completed at: {DateTime.Now.ToLongDateString()}");
        }
        return (ActionResult)new OkObjectResult($"");
    }
}

我删除了

SheetsService service = GetSheetService();
if(service!=null)
{
     DoSomethingFunc(GetInsertCommand(GetSheetVals(service,spreadsheetId)));
}

因为我没有找到哪个 nuget 包有这些方法。

这是我的 function.proj 文件：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Google.Apis" Version="1.40.3" />
    <PackageReference Include="Google.Apis.Auth" Version="1.40.3" />
    <PackageReference Include="Google.Apis.Auth.Mvc" Version="1.40.3" />
    <PackageReference Include="Google.Apis.Sheets.v4" Version="1.40.3.1694" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.28" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

然后它工作正常。我不知道哪些包包含这些方法，因为我对 Google API 了解不多。希望我的回答能给你一些帮助。
