Question

我期待着做一个小邮件.我发现如何在邮件中发送blob附件.但我真的需要发送基于HTML的邮件了.我的目的是用HTML发送邮件。我发现如何在邮件中发送blob附件.但我真的需要发送基于HTML的邮件了.我的目的是发送一个邮件与HTML主体和发送我的blob PDF报告给我们的客户。

我的程序如下。这是与blob附件OK，但没有HTML格式的主体。

Answer 1

我找到了解决方案，当我看我使用的代码。

IF p_html_msg IS NOT NULL THEN
    UTL_SMTP.write_data(l_mail_conn, '--' || l_boundary || UTL_TCP.crlf);
    UTL_SMTP.write_data(l_mail_conn, 'Content-Type: text/html; charset="iso-8859-1"' || UTL_TCP.crlf || UTL_TCP.crlf);

    UTL_SMTP.write_data(l_mail_conn, p_html_msg);
    UTL_SMTP.write_data(l_mail_conn, UTL_TCP.crlf || UTL_TCP.crlf);
  END IF;

而不是

IF p_text_msg IS NOT NULL THEN
    UTL_SMTP.write_data(l_mail_conn, '--' || l_boundary || UTL_TCP.crlf);
    UTL_SMTP.write_data(l_mail_conn, 'Content-Type: text/plain; charset="iso-8859-1"' || UTL_TCP.crlf || UTL_TCP.crlf);

    UTL_SMTP.write_data(l_mail_conn, p_text_msg);
    UTL_SMTP.write_data(l_mail_conn, UTL_TCP.crlf || UTL_TCP.crlf);
  END IF;
