通过 sendgrid 在 Salesforce 中发送带有附件的电子邮件

Question

我正在尝试生成 pdf 并附加到电子邮件并发送。 我正在使用 salesforce 和 sendgrid。 我可以发送电子邮件，但问题是当我尝试附加 pdf 时，电子邮件带有附件，但这已损坏，文件不是空的，但 pdf 显示已损坏（我认为是转换问题) 这是代码

    Messaging.EmailFileAttachment efa = new Messaging.EmailFileAttachment();
    PageReference pdf = Page.include_attachment;
  pdf.getParameters().put('id', 'xxxxxxxxxxxxxxxxxx');
    blob fileBody = pdf.getContentAsPDF();
    efa.setBody(fileBody);
    efa.setFileName('test.pdf');
    efa.setContentType('application/pdf;charset=UTF-8;');
    send('xxxxx@xxxx.com','Test','Body Test', fileBody);

我尝试过使用

pdf.getContentAsPDF();

和

pdf.getContent();

但结果是一样的。

发送方法

public static void send(String emailRecipient, String emailSubject, String emailBody, Blob att){
    Boolean success=true;

    //construct the body of the request
    String requestBody='';
    requestBody += 'to='+EncodingUtil.urlEncode(emailRecipient,'UTF-8');
    requestBody += '&from='+EncodingUtil.urlEncode(user.Email,'UTF-8');
    requestBody += '&fromname='+EncodingUtil.urlEncode(user.Name,'UTF-8');
    requestBody += '&subject='+EncodingUtil.urlEncode(emailSubject,'UTF-8');
    requestBody += '&text='+EncodingUtil.urlEncode(emailBody.trim(),'UTF-8');
    requestBody += '&html='+EncodingUtil.urlEncode(emailBody.trim(),'UTF-8');
    requestBody += '&api_user=xxxxx';
    requestBody += '&api_key=xxxxx';
    requestBody += '&files[attachment.pdf]=@'+ EncodingUtil.base64Encode(att);

    //construct request
    HttpRequest req = new HttpRequest();
    req.setEndpoint('https://sendgrid.com/api/mail.send.json');
    req.setMethod('POST');
    req.setBody(requestBody);
    try{
        //send request
        Http h = new Http();
        HttpResponse res = h.send(req);
        //check response
        String status = res.getStatus();
        if(status.toUpperCase()=='OK'){
            success=true;
        }
        else{
            success=false;
        }
    }
    catch(Exception e){
        success=false;
    }
}

谢谢

现在有一个库/devtoolkit 可以为您执行此操作。在撰写本文时，它处于测试阶段，但它正在运行。免责声明：我在 SendGrid 工作，最近刚刚开发了这个库。

sendgrid-apex

您可以将代码重写为：

...
Blob att = pdf.getContentAsPDF();
public static void send(String emailRecipient, String emailSubject, String emailBody, Blob att){

  SendGrid sendgrid = new SendGrid('username', 'password');

  SendGrid.email email = new SendGrid.Email();
  email.addTo(emailRecipient);
  email.setFrom(user.Email);
  email.setFromName(user.Name);
  email.setSubject(emailSubject);
  email.setText(emailBody.trim());
  email.setHtml(emailBody.trim());
  email.addAttachmentStream("attachment.pdf", att);

  String response = sendgrid.send(email);
}
