asp发邮件功能怎么实现

ASP发邮件功能可以通过引用CDOSYS组件来实现。具体步骤如下：

1. 在ASP页面中引用CDOSYS组件。

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

2. 设置邮件的相关属性，包括发件人、收件人、主题、内容等。

<% objEmail.From = "发件人邮箱" objEmail.To = "收件人邮箱" objEmail.Subject = "邮件主题" objEmail.TextBody = "邮件内容" %> 

3. 设置SMTP服务器的信息。

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

4. 发送邮件。

<% objEmail.Send %> 

完整代码示例：

<%@ Language=VBScript %> <% Set objEmail = CreateObject("CDO.Message") objEmail.From = "发件人邮箱" objEmail.To = "收件人邮箱" objEmail.Subject = "邮件主题" objEmail.TextBody = "邮件内容" objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "SMTP服务器地址" objEmail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25 objEmail.Configuration.Fields.Update objEmail.Send %>
