1. 学习了怎样通过以流的形式发送邮件在这里记下来。这里用到了base64 Encoder编码。在上一篇写到了如何编码这里就没有写了。
2. 代码如下：
3. import java.io.BufferedReader;
4. import java.io.IOException;
5. import java.io.InputStreamReader;
6. import java.io.OutputStream;
7. import java.net.Socket;
8. publicclass SocketTest {
9. publicstaticvoid main(String[] args) throws IOException {
10.Socket sk=new Socket("smtp.sohu.com",25);//spmt协议例如：搜狐smpt.sohu.com
11.OutputStream os=sk.getOutputStream();
12.BufferedReader br=new BufferedReader(new InputStreamReader(sk.getInputStream()));
13.System.out.println(br.readLine());
14.os.write("ehlo name/r/n".getBytes());//计算机名称
15.System.out.println(br.readLine());
16.System.out.println(br.readLine());
17.System.out.println(br.readLine());
18.os.write("auth login/r/n".getBytes());
19.System.out.println(br.readLine());
20.os.write("user/r/n".getBytes()); //用base64 Encoder编码的搜狐用户名
21.System.out.println(br.readLine());
22.os.write("pass/r/n".getBytes());//用base64 Encoder编码的搜狐密码
23.System.out.println(br.readLine());
24.os.write("mail from:<邮箱名>/r/n".getBytes());//自己搜狐的邮箱
25.System.out.println(br.readLine());
26.os.write("rcpt to:<邮箱名>/r/n".getBytes());//要接收用户的邮箱
27.System.out.println(br.readLine());
28.os.write("data/r/n".getBytes());
29.System.out.println(br.readLine());
30.os.write("from:<邮箱名>/r/n".getBytes());//自己搜狐的邮箱
31.os.write("to:<邮箱名>/r/n".getBytes());//要接收用户的邮箱
32.os.write("subject:你好/r/n".getBytes());//邮箱主题
33.os.write("/r/n".getBytes());
34.os.write("小李同志你好/r/n".getBytes());//邮箱内容
35.os.write("./r/n".getBytes());//以点结束邮箱内容
36.System.out.println(br.readLine());
37.os.write("quit/r/n".getBytes());//退出邮箱
38.br.close();
39.os.close();
40.sk.close();
