我使用 AWS 网页中的示例来检查我是否可以使用 AWS SES SDK 接收电子邮件。

显示邮件已发送成功，但查看我的邮箱账户却没有收到邮件。

发件人的电子邮件已经过验证。

代码与给定的简单相同。只有电子邮件地址不同。

当我在 VS 2017 中粘贴代码时，会为 Client.SendEmail() 引发错误。

我将其修改为推荐给 Client.SendEmailAsync()。不知道问题云在哪里。

                    Message = new Message 
                    { 
                        Subject = new Content(subject), 
                        Body = new Body 
                        { 
                            Html = new Content 
                            {

                                Data = htmlBody

                            } 
                        } 
                    }, 
 
                    ConfigurationSetName = configSet 
                }; 
                try 
                { 
                    Console.WriteLine("Sending email using Amazon SES..."); 
                    var response = client.SendEmailAsync(sendRequest); 
                    Console.WriteLine("The email was sent successfully."); 
                } 
                catch (Exception ex) 
                { 
                    Console.WriteLine("The email was not sent."); 
                    Console.WriteLine("Error message: " + ex.Message); 
 
                } 
            } 
 
            Console.Write("Press any key to continue..."); 
            Console.ReadKey(); 
        } 
    } 
} 

请您参考如下方法:

错误

Main 方法在发送电子邮件之前结束，因为我们没有等待 Task response 完成。

SendEmailAsync 返回一个 Task，这意味着这两行代码是相同的:

1. var response = client.SendEmailAsync(sendRequest);

2. 任务响应 = client.SendEmailAsync(sendRequest);

解决方案

如果您安装了最新版本的 Visual Studio 并启用了 C#7.1，则可以利用 async Task Main 并使用 await 关键字在不同线程和 Main 上运行 SendEmailAsync 的代码在 SendEmail 完成之前不会结束。

如果您使用的是旧版本的 Visual Studio，您可以添加 .GetAwaiter().GetResult()，这也将确保 Main 直到SendEmail 已完成，但 SendEmailAsync 将锁定当前线程。

C#7.1及以上(首选)

static async Task Main(string[] args) 
{ 
 
    using (var client = new AmazonSimpleEmailServiceClient(RegionEndpoint.USEast1))  
    { 
        var sendRequest = new SendEmailRequest 
        { 
            Source = senderAddress, 
            Destination = new Destination 
            { 
                ToAddresses = 
                new List<string> { receiverAddress } 
            }, 
            Message = new Message 
            { 
                Subject = new Content(subject), 
                Body = new Body 
                { 
                    Html = new Content 
                    { 
                        Charset = "UTF-8", 
                        Data = htmlBody 
                    }, 
                    Text = new Content 
                    { 
                        Charset = "UTF-8", 
                        Data = textBody 
                    } 
                } 
            }, 
 
            ConfigurationSetName = configSet 
        }; 
        try 
        { 
            Console.WriteLine("Sending email using Amazon SES..."); 
            var response = await client.SendEmailAsync(sendRequest); 
            Console.WriteLine("The email was sent successfully."); 
        } 
        catch (Exception ex) 
        { 
            Console.WriteLine("The email was not sent."); 
            Console.WriteLine("Error message: " + ex.Message); 
 
        } 
    } 
 
    Console.Write("Press any key to continue..."); 
    Console.ReadKey(); 
} 

C#7.0及以下

static void Main(string[] args) 
{ 
 
    using (var client = new AmazonSimpleEmailServiceClient(RegionEndpoint.USEast1))  
    { 
        var sendRequest = new SendEmailRequest 
        { 
            Source = senderAddress, 
            Destination = new Destination 
            { 
                ToAddresses = 
                new List<string> { receiverAddress } 
            }, 
            Message = new Message 
            { 
                Subject = new Content(subject), 
                Body = new Body 
                { 
                    Html = new Content 
                    { 
                        Charset = "UTF-8", 
                        Data = htmlBody 
                    }, 
                    Text = new Content 
                    { 
                        Charset = "UTF-8", 
                        Data = textBody 
                    } 
                } 
            }, 
 
            ConfigurationSetName = configSet 
        }; 
        try 
        { 
            Console.WriteLine("Sending email using Amazon SES..."); 
            var response = client.SendEmailAsync(sendRequest).GetAwaiter().GetResult(); 
            Console.WriteLine("The email was sent successfully."); 
        } 
        catch (Exception ex) 
        { 
            Console.WriteLine("The email was not sent."); 
            Console.WriteLine("Error message: " + ex.Message); 
 
        } 
    } 
 
    Console.Write("Press any key to continue..."); 
    Console.ReadKey(); 
}
