java如何打印所有收件箱电子邮件
我对Java非常陌生,对端口、服务器或socket一无所知,所以我希望有人能帮助我。我想做一个小程序,可以打印你收件箱中的所有邮件(已读和未读)
我在网上找到了这段代码,但它只给我发送文件夹中最早的信息
public class EmailService {
String server = "pop.gmail.com";
int port = 995;
static String username;
static String password;
SSLSocket socket;
BufferedReader input;
PrintWriter output;
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
username = s.next() + "@gmail.com";
password = s.next();
new EmailService();
}
public EmailService() {
try {
SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
socket = (SSLSocket)sslsocketfactory.createSocket(server, port);
input = new BufferedReader(new InputStreamReader(socket.getInputStream()));
// After each println you MUST flush the buffer, or it won't work properly.
// The true argument makes an automatic flush after each println.
output = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()), true);
connect();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public void connect() throws IOException {
System.out.print("Greeting message: ");
String response = readOneLine();
System.out.println(response);
// Username
output.println("USER " + username);
response = readOneLine();
System.out.println(response);
// Password
output.println("PASS " + password);
response = readOneLine();
System.out.println(response);
output.println("RETR 1");
while (!response.equals(".")) {
response = readOneLine();
System.out.println(response);
}
}
public String readOneLine() throws IOException {
return input.readLine();
}
}
