asp發郵件功能怎么實現

ASP發郵件功能可以通過引用CDOSYS組件來實現。具體步驟如下：

1. 在ASP頁面中引用CDOSYS組件。

<%@ Language=VBScript %>
<%
Set objEmail = CreateObject("CDO.Message")
%>

2. 設置郵件的相關屬性，包括發件人、收件人、主題、內容等。

<%
objEmail.From = "發件人郵箱"
objEmail.To = "收件人郵箱"
objEmail.Subject = "郵件主題"
objEmail.TextBody = "郵件內容"
%>

3. 設置SMTP服務器的信息。

<%
objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "SMTP服務器地址"
objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objEmail.Configuration.Fields.Update
%>

4. 發送郵件。

<%
objEmail.Send
%>

完整代碼示例：

<%@ Language=VBScript %>
<%
Set objEmail = CreateObject("CDO.Message")
objEmail.From = "發件人郵箱"
objEmail.To = "收件人郵箱"
objEmail.Subject = "郵件主題"
objEmail.TextBody = "郵件內容"
objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "SMTP服務器地址"
objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objEmail.Configuration.Fields.Update
objEmail.Send
%>
