Adobe Air javascript imap ssl - 无法发出“列表”命令 - 错误的未知命令

发布于 2024-12-28 00:02:05 字数 764 浏览 2 评论 0原文

我正在 Adobe Air 中编写一个应用程序来从 Gmail 获取电子邮件。我能够使用 SSL 连接并成功登录，但随后我无法继续提取电子邮件。我认为这是因为未维护 SSL 会话。每次我发出命令时，会话都会丢失。

要获取电子邮件，我必须发送登录请求，然后发送 LIST "" "*" 命令。但由于登录后连接中断，当我发送 LIST 命令时，它会作为一个新连接启动，并认为我尚未登录，并给出错误消息 a001 BAD Unknown command gf9if3619638pbc .89

代码如下。有什么想法可以实现这一点，或者这是否可能？

var socket;
function login() {
    socket = new air.SecureSocket();
    socket.connect('imap.gmail.com', 993);
    socket.writeUTFBytes("\n"+"a001 LOGIN username password");
    socket.addEventListener(air.ProgressEvent.SOCKET_DATA, socketDataHandler);
}

function fetchEmail() {
    socket = new air.SecureSocket();
    socket.connect(server, port);
    socket.writeUTFBytes("\n"+'a001 LIST "" "*"');
}

I am writing an application in Adobe Air to fetch emails from Gmail. I am able to connect with SSL and successfully login, but then I'm unable to proceed further in fetching emails. I think this is because the SSL session is not maintained. Each time i issue a command, the session is lost.

To fetch email, I have to send a login request and then a LIST "" "*" command. But since the connection breaks after login, when i send that LIST command, it starts as a new connection and thinks I haven't logged in, and give the error message a001 BAD Unknown command gf9if3619638pbc.89

The code is below. Any idea to implement this, or is this even possible?

var socket;
function login() {
    socket = new air.SecureSocket();
    socket.connect('imap.gmail.com', 993);
    socket.writeUTFBytes("\n"+"a001 LOGIN username password");
    socket.addEventListener(air.ProgressEvent.SOCKET_DATA, socketDataHandler);
}

function fetchEmail() {
    socket = new air.SecureSocket();
    socket.connect(server, port);
    socket.writeUTFBytes("\n"+'a001 LIST "" "*"');
}

这并非特定于 SSL/TLS。在这里，当您想要记录时，您将创建一个新连接；当您想要获取电子邮件时，您将创建另一个新连接。就服务器而言，这是两个完全不同的连接。删除 fetchEmail() 中的这些行应该是一个开始：

socket = new air.SecureSocket();
socket.connect(server, port);

此外，您需要确保在 LOGIN 命令（或任何其他命令实际上），然后再继续执行下一个命令。

This is not specific to SSL/TLS. Here, you're creating a new connection when you want to log and another new connection when you want to fetch the e-mails. As far as the server is concerned, these are two completely distinct connections. Removing these lines in fetchEmail() should be a start:

socket = new air.SecureSocket();
socket.connect(server, port);

In addition, you'll need to make sure you get the appropriate response code after the LOGIN command (or any other command in fact) before proceeding to the next command.
