ASP怎么使用CDOSYS发送电子邮件

在ASP中使用CDOSYS发送电子邮件的步骤如下：

1. 在ASP页面中引入CDOSYS对象：

<%
Set objEmail = Server.CreateObject("CDO.Message")
%>

2. 设置邮件的相关属性，包括发送者、收件人、主题、内容等：

<%
objEmail.From = "sender@example.com"
objEmail.To = "recipient@example.com"
objEmail.Subject = "Sample Email"
objEmail.HTMLBody = "Hello, this is a sample email!"
%>

3. 设置SMTP服务器的相关配置：

<%
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.example.com"
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusername") = "username"
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password"
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
objEmail.Configuration.Fields.Update
%>

请注意替换上述代码中的SMTP服务器地址、端口号、身份验证信息等为您实际使用的值。

4. 发送邮件：

<%
objEmail.Send
%>

完整的示例代码如下：

<%
Set objEmail = Server.CreateObject("CDO.Message")
objEmail.From = "sender@example.com"
objEmail.To = "recipient@example.com"
objEmail.Subject = "Sample Email"
objEmail.HTMLBody = "Hello, this is a sample email!"
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtp.example.com"
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendusername") = "username"
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password"
objEmail.Configuration.Fields.Item _
("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
objEmail.Configuration.Fields.Update
objEmail.Send
%>

请注意，上述代码中的SMTP服务器需要提供身份验证信息，您需要将"username"和"password"替换为您自己的SMTP服务器的用户名和密码。此外，还要确保CDOSYS组件已经在服务器上正确安装和配置。
