Question

我使用GO并尝试通过sendgrid API v3（https://github.com/sendgrid/sendgrid-go没有Mail Helper Class）发送邮件。但是当我使用这段代码时：

"content": [
    {
      "type": "text/html", 
      "value": "<html><head></head><body>Hello You link <a href="http://example.com/reschedule?id=12334">Click</a></body></html>"
    }
  ],

我收到错误：

400 {＆＃34;错误＆＃34;：[{＆＃34;消息＆＃34;：＆＃34;错误请求＆＃34;＆＃34;字段＆＃34;：null，＆＃34;帮助＆＃34;：空}]}

但是这段代码可以正常工作：

"content": [
    {
      "type": "text/html", 
      "value": "<html><head></head><body>Hello!</body></html>"
    }
  ],

我认为特殊字符有问题，但我怎么能解决它？谢谢！

Answer 1

需要这样做：

<div class=\"ad_box\"><img class=\"banner\" src=\"some_ad.png\" alt=\"\" \/>

Example
    "content": [
        {
          "type": "text/html", 
          "value": "<html><head></head><body>Hello You link <a href=\"http://example.com/reschedule?id=12334\">Click</a></body></html>"
        }
      ],

Answer 2

我遇到了同样的问题，相同的转义符，解决的办法是使用官方客户端及其助手。

示例代码：

from := mail.NewEmail("from", "from@mail.com")
to := mail.NewEmail("to", "to@mail.com")
content := mail.NewContent("text/html", contentHtml)

email := mail.NewV3MailInit(from, "Sample about sendgrid client", to, content)

personalization := mail.NewPersonalization()
personalization.AddTos(to)
email.AddPersonalizations(personalization)

client := sendgrid.NewSendClient(os.Getenv("SENDGRID_API_KEY"))
response, err = client.Send(email)
if err != nil {
    return fmt.Errorf("Cannot send the email: %v", err)
}

if response.StatusCode != 202 {
    return fmt.Errorf("Cannot send the email: %s", response.Body)
}
