使用带有 java 的 SendGrid 发送电子邮件

Question

我是软件开发的新手，一直在尝试用 Java 开发一个应用程序，以使用 SendGrid 发送多内容电子邮件（纯文本和 html 文件），但我只得到 HTML 文件。请帮我解决这个问题。这是我的代码。

Email from = new Email("sebatti20@gmail.com");
String subject = "Sending with SendGrid is Fun";
Content content = new Content();
content.setType("text/plain");
content.setValue("This is a simple text");
content.setType("text/html");
content.setValue("This is an HTML text");
Personalization personalization = new Personalization();
Email to = new Email();
to.setEmail("sabbyelavumkal@gmail.com");
personalization.addTo(to);
Email to2 = new Email();
to2.setEmail("jojimathew.mec@gmail.com");
personalization.addTo(to2);
Email Cc = new Email();
Cc.setEmail("sebastianthomas.mec@gmail.com");
personalization.addCc(Cc);
Mail mail = new Mail();
mail.setFrom(from);
mail.setSubject(subject);
mail.addContent(content);
mail.addPersonalization(personalization);
endGrid sg = new SendGrid("SENDGRID API");
Request request = new Request();
try {
    request.setMethod(Method.POST);
    request.setEndpoint("mail/send");
    request.setBody(mail.build());
    Response response = sg.api(request);
    System.out.println(response.getStatusCode());
    System.out.println(response.getBody());
    System.out.println(response.getHeaders());
} catch (IOException ex) {
    throw ex;
}

Answer 1

您使用 HTML 覆盖文本内容。
如果你想要两者，你应该这样写：

Content plainContent = new Content("text/plain", "This is a simple text");
Content htmlContent = new Content("text/html", "This is an HTML text");
mail.addContent(plainContent);
mail.addContent(htmlContent);
