Escape special characters while sending email through AWS ses

问题

你好，我是你的中文翻译助手。以下是你要翻译的内容：

你好，我正在使用AWS SES SDK V2发送电子邮件。我遇到了一个问题，发送者的姓名是Michael čisto。如果我直接将这个姓名传递给AWS的电子邮件输入结构体，就会出现以下错误：

operation error SESv2: SendEmail, https response error StatusCode: 400, BadRequestException: Missing '"'

这是我的代码：

  1. package main
  3. import (
  4. 	"context"
  6. 	"github.com/aws/aws-sdk-go-v2/aws"
  7. 	awsconfig "github.com/aws/aws-sdk-go-v2/config"
  8. 	"github.com/aws/aws-sdk-go-v2/service/sesv2"
  9. 	"github.com/aws/aws-sdk-go-v2/service/sesv2/types"
  10. )
  12. func main() {
  13. 	name := "Michael čisto"
  14. 	body := "test email body"
  15. 	subject := "test email"
  16. 	CharSet := "UTF-8"
  17. 	/* Assemble the email */
  18. 	input := &sesv2.SendEmailInput{
  19. 		Destination: &types.Destination{
  20. 			CcAddresses: []string{},
  21. 			ToAddresses: []string{receiverEmail},
  22. 		},
  23. 		Content: &types.EmailContent{
  24. 			Simple: &types.Message{
  25. 				Body: &types.Body{
  26. 					Html: &types.Content{
  27. 						Charset: aws.String(CharSet),
  28. 						Data:    aws.String(body),
  29. 					},
  30. 				},
  31. 				Subject: &types.Content{
  32. 					Charset: aws.String(CharSet),
  33. 					Data:    aws.String(subject),
  34. 				},
  35. 			},
  36. 		},
  37. 		ReplyToAddresses: []string{"\"" + name + "\" <" + senderEmail + ">"},
  38. 		FromEmailAddress: aws.String("\"" + name + "\" <" + senderEmail + ">"),
  39. 	}
  40. 	cfg, err := awsconfig.LoadDefaultConfig(context.TODO(),
  41. 		awsconfig.WithRegion("us-east-1"),
  42. 	)
  43. 	client := sesv2.NewFromConfig(cfg)
  44. 	emailResp, err = client.SendEmail(context.TODO(), input)
  45. }

有人可以帮我解决如何在GO中转义这些特殊字符的问题吗？

英文:

Hello I am using AWS SES SDK V2 to send emails. I have a case where sender name is like Michael čisto. If I pass this name directly to AWS email input struct then it gives me following error:

operation error SESv2: SendEmail, https response error StatusCode: 400, BadRequestException: Missing &#39;&quot;&#39;

Here is my code:

  1. package main
  3. import (
  4. 	&quot;context&quot;
  6. 	&quot;github.com/aws/aws-sdk-go-v2/aws&quot;
  7. 	awsconfig &quot;github.com/aws/aws-sdk-go-v2/config&quot;
  8. 	&quot;github.com/aws/aws-sdk-go-v2/service/sesv2&quot;
  9. 	&quot;github.com/aws/aws-sdk-go-v2/service/sesv2/types&quot;
  10. )
  12. func main() {
  13. 	name := &quot;Michael čisto&quot;
  14. 	body := &quot;test email body&quot;
  15. 	subject := &quot;test email&quot;
  16. 	CharSet := &quot;UTF-8&quot;
  17. 	/* Assemble the email */
  18. 	input := &amp;sesv2.SendEmailInput{
  19. 		Destination: &amp;types.Destination{
  20. 			CcAddresses: []string{},
  21. 			ToAddresses: []string{receiverEmail},
  22. 		},
  23. 		Content: &amp;types.EmailContent{
  24. 			Simple: &amp;types.Message{
  25. 				Body: &amp;types.Body{
  26. 					Html: &amp;types.Content{
  27. 						Charset: aws.String(CharSet),
  28. 						Data:    aws.String(body),
  29. 					},
  30. 				},
  31. 				Subject: &amp;types.Content{
  32. 					Charset: aws.String(CharSet),
  33. 					Data:    aws.String(subject),
  34. 				},
  35. 			},
  36. 		},
  37. 		ReplyToAddresses: []string{&quot;\&quot;&quot; + name + &quot;\&quot; &lt;&quot; + senderEmail + &quot;&gt;&quot;},
  38. 		FromEmailAddress: aws.String(&quot;\&quot;&quot; + name + &quot;\&quot; &lt;&quot; + senderEmail + &quot;&gt;&quot;),
  39. 	}
  40. 	cfg, err := awsconfig.LoadDefaultConfig(context.TODO(),
  41. 		awsconfig.WithRegion(&quot;us-east-1&quot;),
  42. 	)
  43. 	client := sesv2.NewFromConfig(cfg)
  44. 	emailResp, err = client.SendEmail(context.TODO(), input)
  45. }

Can anyone help me to figure out how to escape these kind of characters in GO ?

尝试使用mail.Address.String来格式化地址：

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"net/mail"
  6. )
  8. func main() {
  9. 	a := mail.Address{Name: "Michael čisto", Address: "sender@example.com"}
  10. 	fmt.Println(a.String())
  11. 	// 输出:
  12. 	// =?utf-8?q?Michael_=C4=8Disto?= <sender@example.com>
  13. }

如果您的域名包含非ASCII字符：

请注意，Amazon SES不支持SMTPUTF8扩展。如果地址的域部分（@符号后面的部分）包含非ASCII字符，则必须使用Punycode进行编码（请参阅types.BulkEmailEntry）。mail.Address.String不会为您执行此操作。但是，您可以使用idna.ToASCII自行转换域名。

英文:

Try to format the address using mail.Address.String:

  1. package main
  3. import (
  4. 	&quot;fmt&quot;
  5. 	&quot;net/mail&quot;
  6. )
  8. func main() {
  9. 	a := mail.Address{Name: &quot;Michael čisto&quot;, Address: &quot;sender@example.com&quot;}
  10. 	fmt.Println(a.String())
  11. 	// Output:
  12. 	// =?utf-8?q?Michael_=C4=8Disto?= &lt;sender@example.com&gt;
  13. }

In case your domain contains non-ASCII characters:

Please note that Amazon SES does not support the SMTPUTF8 extension. If the domain part of an address (the part after the @ sign) contains non-ASCII characters, they must be encoded using Punycode (see types.BulkEmailEntry). mail.Address.String does not do this for you. But you can use idna.ToASCII to convert the domain yourself.
