无法在门户中将 azure 队列存储与 azure 函数（调度程序触发器）绑定

Question

我正在构建一个 Azure 函数应用程序来访问 Azure 队列存储（调度程序触发器）、检索消息以及使用 SendGrid 发送电子邮件。

我花了很多时间调试和爬取 Whosebug，但仍然收到相同的错误消息。

这是错误信息。

[Error] Exception while executing function: Functions.ScheduledMailCSharpHobby. mscorlib: Exception has been thrown by the target of an invocation. Microsoft.WindowsAzure.Storage: Settings must be of the form "name=value".

文件：run.csx

#r "SendGrid"
#r "Microsoft.WindowsAzure.Storage"

using System;
using SendGrid.Helpers.Mail;
using Microsoft.Azure;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Queue;


public static Mail Run(TimerInfo myTimer, TraceWriter log)
{
    var today = DateTime.Today.ToShortDateString();
    log.Info($"Generating daily report for {today} at {DateTime.Now}");
    
    Mail message = new Mail()
    {
        Subject = $"Daily Report for {today}"
    };

    CloudStorageAccount storageAccount = CloudStorageAccount.Parse("serverlessbdbxxxxxxx");
    // Get queue... create if does not exist.
    CloudQueueClient queueClient = storageAccount.CreateCloudQueueClient();
    CloudQueue queue = queueClient.GetQueueReference("memberqueue");
    // Peek at the next message
    CloudQueueMessage peekedMessage = queue.PeekMessage();

    // Display message.
    log.Info(peekedMessage.AsString);

    var mail_content = peekedMessage.AsString;

    Content content = new Content
    {
        Type = "text/plain",
        Value = $"Hi! {mail_content}"
    };

    message.AddContent(content);
    return message;
}

文件：function.json

{
  "bindings": [
    {
      "type": "timerTrigger",
      "name": "myTimer",
      "schedule": "0 0 17 * * *",
      "direction": "in"
    },
    {

    }

}

问题是由这行引起的。

CloudStorageAccount storageAccount = CloudStorageAccount.Parse("serverlessbdbxxxxxxx");

要访问存储帐户连接字符串，您需要

将连接字符串存储在门户上函数应用程序的应用程序设置中。

使用 GetEnvironmentVariable() 获取连接字符串。

CloudStorageAccount storageAccount = CloudStorageAccount.Parse(Environment.GetEnvironmentVariable("StorageConnectionString"));
