c# - sendgrid 在 Azure 功能中向多个收件人发送电子邮件失败

问题描述

（有关此问题的完整版本，请参阅 https://social.msdn.microsoft.com/Forums/en-US/20bb5b37-82af-4cf3-8a59-04e5f19572bc/send-email-to-multiple-recipients-使用-sendgrid-failure?forum=AzureFunctions )

发送给单个收件人成功。但无法在 Azure 功能中发送给多个收件人或抄送/密送。

尝试了几种格式，包括

{ "to": [{ "email": ["john.doe@example.com", "sendgridtesting@gmail.com" ] }] }

这似乎是天蓝色功能的极限。但还不确定哪里出了问题。请参阅下面的“绑定”，

{

"bindings": [

{

"name": "telemetryEvent",

"type": "serviceBusTrigger", 

"direction": "in",

"queueName": "threshold-email-queue",

"connection": "RootManageSharedAccessKey_SERVICEBUS",

"accessRights": "Manage"

},

{

"type": "sendGrid",

"name": "$return",

"apiKey": "SendGridKey",

"direction": "out",

"from": "ABC@sample.com",

"to": [{
"email": ["test1@sample1.com", "test2@sample2.com" ]
}]

}

],
"disabled": false

}

解决方案

我使用 HTTP 触发器做了我的示例，但基于此，您将能够使其与服务总线触发器一起使用。

我的function.json：

{
  "bindings": [
    {
      "authLevel": "function",
      "name": "req",
      "type": "httpTrigger",
      "direction": "in",
      "methods": [
        "get",
        "post"
      ]
    },
    {
      "type": "sendGrid",
      "name": "mails",
      "apiKey": "MySendGridKey",
      "direction": "out",
      "from":"samples@functions.com"
    }
  ],
  "disabled": false
}

我的 run.csx：

#r "SendGrid"

using System;
using System.Net;
using SendGrid.Helpers.Mail;

public static HttpResponseMessage Run(HttpRequestMessage req, TraceWriter log, ICollector<Mail> mails)
{
    log.Info("C# HTTP trigger function processed a request.");

    Mail message = new Mail()
    {
        Subject = $"Hello world from the SendGrid C#!"
    };

    var personalization = new Personalization();
    personalization.AddTo(new Email("foo@bar.com"));  
    personalization.AddTo(new Email("foo2@bar.com")); 
    // you can add some more recipients here 

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

    message.AddContent(content);  
    message.AddPersonalization(personalization); 
    mails.Add(message);

    return null;
}

我使用这个源来构建我的示例： Azure Function SendGrid
