Sendgrid 没有在作为控制台应用程序运行的按需 azure webjob 中发送电子邮件

Question

我有一个作为控制台应用程序运行的按需 azure webjob。

目标是向客户发送电子邮件。

问题是它不发送电子邮件。

我的代码大量来自msdn 部分如何：发送电子邮件。以下是我的代码 sn-p。

class Program
{
  static void Main(string[] args)
    {
Execute(Environment.GetEnvironmentVariable("WEBJOBS_COMMAND_ARGUMENTS")).Wait();
    }

    static async Task Execute(string email)
    {
        DeserializedCustomer customer = JsonConvert.DeserializeObject<DeserializedCustomer>(email);
        var apiKey = Environment.GetEnvironmentVariable("SENDGRID_APIKEY");
        var client = new SendGridClient(apiKey);
        SendGridMessage msg = new SendGridMessage()
        {
            From = new EmailAddress(customer.Email, "From Email"),
            Subject = $"Inquiry by - {customer.FirstName} {customer.LastName}",
            PlainTextContent = customer.Comments + Environment.NewLine + $"Phone : {customer.Phone}",
        };
        msg.AddTo(new EmailAddress(ToMail, ToMailName));

        if (!String.IsNullOrWhiteSpace(customer.Attachment))
        {
            List<Attachment> attachments = new List<Attachment>()
            {
                new Attachment()
                {
                    Content = customer.Attachment,
                    Type = customer.AttachmentType,
                    Filename = customer.AttachmentFileName,
                    Disposition = "inline",
                    ContentId = customer.AttachmentFileName + Guid.NewGuid()
                }
            };
            msg.Attachments = attachments;
        }
        await client.SendEmailAsync(msg);

    }
}

搜索我发现了一个 SO post 给 sendgrid 时间在控制台应用程序中发送电子邮件的地方

增加时间也无济于事。

如果从作为控制台应用程序运行的 azure webjobs 发送电子邮件有一些奇怪之处，那么我不知道。

进一步搜索我发现this SO 帖子他们成功测试了在控制台应用程序中发送电子邮件，所以我认为它可能会有所帮助，但它没有发送电子邮件。

以上所有示例都已有一年多的历史，目前都没有工作。

我尝试使用早期版本的 SendGrid 库，但我卡在了

var transportWeb = new Web(credentials);
transportWeb.DeliverAsync(myMessage);

因为 SendGrid 库已更新。

我在 github 上找到了 this，它明确指出控制台应用程序仅适用于 transportWeb.DeliverAsync(myMessage).Wait

因此我正在尝试使用 transportWeb。

Azure 与作为控制台应用程序运行的按需 Web 作业是否合并？

谁能帮忙？

更新

在 Randy Minder 的帮助下，我将代码更新为以下内容

       static async Task Execute(string email)
    {
        try
        {

            DeserializedCustomer customer = new DeserializedCustomer();
            customer = JsonConvert.DeserializeObject<DeserializedCustomer>(email);
            Console.WriteLine(customer);
            SendGridMessage msg = new SendGridMessage();
            msg.From = new MailAddress(customer.EmailAddress, "From Email");
            msg.Subject = $"Inquiry by - {customer.FirstName} {customer.LastName}";
            msg.Text = customer.Comments + Environment.NewLine + $"Phone : {customer.Phone}";

            msg.AddTo(ToMail);

            // Create a network credentials object
            var credentials = new NetworkCredential(Environment.GetEnvironmentVariable("UserName"), Environment.GetEnvironmentVariable("Password"));

            var transportWeb = new SendGrid.Web(credentials);
            transportWeb.DeliverAsync(msg).Wait();
        }
        catch (Exception ex)
        {
            DateTime now = DateTime.Now;
            Trace.TraceError($"{now.ToLongDateString()} {now.ToLongTimeString()}" + Environment.NewLine + new ExceptionSerializer(ex));
        }
    }

我正在使用 SendGrid 6.1.0

 <package id="Sendgrid" version="6.1.0" targetFramework="net47" />

我没有遇到任何异常，我的 webjob 运行成功

但是我没有收到任何电子邮件

Answer 1

当尝试在控制台应用程序中通过 SendGrid 发送电子邮件时，您必须有所不同。这是我在控制台应用程序中使用的一种方法：

/// <summary>
/// Send the email async in a console app.
/// </summary>
public async Task SendAsync()
{
    // Create a network credentials object
    var credentials = new NetworkCredential(azureUserName, azurePassword);

    // Create an Web transport for sending the email
    var transportWeb = new Web(credentials);

    transportWeb.DeliverAsync(this._email).Wait();
}

这是我在非控制台应用程序中使用的：

    /// <summary>
    /// Send the email async in backend or MVC code.
    /// </summary>
    public async Task SendAsync()
    {
        // Create a network credentials object
        var credentials = new NetworkCredential(azureUserName, azurePassword);

    // Create an Web transport for sending the email
    var transportWeb = new Web(credentials);

    await transportWeb.DeliverAsync(this._email).ConfigureAwait(false);
}

实际的电子邮件对象包含在this._email 中。

根据你的描述，我这边也做了一个测试demo，效果不错。我用的sendgird SDK是9.90。

详细代码如下：

class Program
{
    static void Main(string[] args)
    {

         string  serializedEmail = args[0];

        Console.WriteLine($"SerializedEmail - {serializedEmail}");

        Customer customer = JsonConvert.DeserializeObject<Customer>(args[0]);

        //Customer customer = new Customer() { Name = "aaaa" };
        Execute(customer).Wait();
        Console.WriteLine(customer.Name);
        Console.ReadLine();

    }


    static async Task Execute(Customer customer)
    {

        var client = new SendGridClient("apikey");
        var from = new EmailAddress("sendgird@xxxxxx.com", "Example User");
        var subject = "Sending with SendGrid is Fun";
        var to = new EmailAddress("sendgird@xxxxxxx.com", "Example User");
        var plainTextContent = $"Name : {customer.Name}";
        var htmlContent = "<strong>and easy to do anywhere, even with C#</strong>";
        var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
        var response = await client.SendEmailAsync(msg);
    }


}

public class Customer
{
    public string Name { get; set; }
}

但是我没有收到任何电子邮件

我建议你可以先访问这个url，看看sendgird已经把邮件发到正确的邮箱了。

结果是这样的：
