【问题描述】：

我正在开发我的 Telegram 机器人。我知道，在我的国家，Telegram 被锁定，所以我决定通过代理连接到 Telegram Bot API。当我尝试运行此代码时：

import org.telegram.telegrambots.ApiContextInitializer;
import org.telegram.telegrambots.bots.DefaultBotOptions;
import org.telegram.telegrambots.meta.ApiContext;
import org.telegram.telegrambots.meta.TelegramBotsApi;
import org.telegram.telegrambots.meta.exceptions.TelegramApiRequestException;

public class SharperBotApp {
    private static final String PROXY_HOST = "89.200.150.35";
    private static final int PROXY_PORT = 37499;//TODO

    public static void main(String[] args) {
        ApiContextInitializer.init();
        TelegramBotsApi botsApi = new TelegramBotsApi();

        DefaultBotOptions botOptions = ApiContext.getInstance(DefaultBotOptions.class);

        botOptions.setProxyHost(PROXY_HOST);
        botOptions.setProxyPort(PROXY_PORT);
        botOptions.setProxyType(DefaultBotOptions.ProxyType.SOCKS4);

        try {
            botsApi.registerBot(new SharperBot(botOptions));
        } catch (TelegramApiRequestException e) {
            e.printStackTrace();
        }
    }
}

我得到了这个堆栈跟踪：

我用谷歌搜索了它，发现人们建议使用代理......但我已经做到了！所以我决定使用VPN。我在笔记本电脑上安装了 Windscribe，但随后也出现了这个异常。我应该怎么做？也许，我做错了什么？（我的笔记本电脑上安装了 Debian 9）。

【问题讨论】：

也许会有用的信息：当我在谷歌浏览器中转到api.telegram.org:443时，没关系
你终于搞定了吗？有什么解决办法吗？
@PetrAleksandrov，是的，我明白了。下面我发布了一个解决方案。检查它，如果它对你有帮助，请点赞。

【解决方案1】：

我明白了。解决方案很简单。您只需要使用 tor 代理即可：

public class MyApplication {
    public static void main(String[] args) {
        System.getProperties().put("proxySet", true);
        System.getProperties().put("socksProxyHost", 127.0.0.1);
        System.getProperties().put("socksProxyPort", 9050);
    }
}

但之前你应该安装tor服务：

sudo apt-get install tor
