Telegram用户手机号获取方式这个被问过很多次,其实还是有挺多方式的,我用过的一种有效的方法,会涉及一些社会工程学,但可以以批量推广收集用户手机号,就是建立一些钓鱼机器人,利用telegram内置分享手机号码功能,这些机器人会提示用户分享他们的电话号码(Telegram 的内置功能)以继续使用机器人的服务,效果如下:
而且方便的是有可以直接复用的机器人和官方api,现有的解决方案(如 @protestchat_bot 或 @Checknumb_bot)已经发挥了这一作用。上面测试机器人获取到的绑定手机号码结果可以在@TgAnalyst_bot中输入目标帐户的 ID查询。
这种机器人可以配合各类github中功能机器人使用,买卖货币,Ins、x、facebook自动关注、还有各种大火的AI制图改图之类的都可以使用,且可以直接无脑推广收集,钓鱼手段主要还是靠思路,多翻翻官方文档总有适合你的方式。

如果想从头写,下面这个这个是个简单的参考demo:
使用的是Telegram Bot API(https://www.nuget.org/packages/Telegram.Bot),在向用户请求时可以获取电话号码,且用户不用填写号码,系统自动获取号码,效果如下:
当用户点击/myNumber
用户会有确认界面:
就可以得到用户绑定的电话号码
控制台输出效果:
看一下这个简单的控制台应用程序,但是您需要做一些更改来处理数字:
添加Handler.ch
以下几行到BotOnMessageReceived
if (message.Type == MessageType.Contact && message.Contact != null)
{
Console.WriteLine($"Phone number: {message.Contact.PhoneNumber}");
}
如果某一天存储库被删除,则需要以下代码:
Program.cs
public static class Program
{
private static TelegramBotClient? bot;
public static async Task Main()
{
bot = new TelegramBotClient(/*TODO: BotToken hier*/);
User me = await bot.GetMeAsync();
Console.Title = me.Username ?? "My awesome bot";
using var cts = new CancellationTokenSource();
ReceiverOptions receiverOptions = new() { AllowedUpdates = { } };
bot.StartReceiving(Handlers.HandleUpdateAsync,
Handlers.HandleErrorAsync,
receiverOptions,
cts.Token);
Console.WriteLine($"Start listening for @{me.Username}");
Console.ReadLine();
cts.Cancel();
}
}
Handlers.cs
internal class Handlers
{
public static Task HandleErrorAsync(ITelegramBotClient botClient, Exception exception, CancellationToken cancellationToken)
{
var errorMessage = exception switch
{
ApiRequestException apiRequestException => $"Telegram API Error:\n[{apiRequestException.ErrorCode}]\n{apiRequestException.Message}",
_ => exception.ToString()
};
Console.WriteLine(errorMessage);
return Task.CompletedTask;
}
public static async Task HandleUpdateAsync(ITelegramBotClient botClient, Update update, CancellationToken cancellationToken)
{
var handler = update.Type switch
{
UpdateType.Message => BotOnMessageReceived(botClient, update.Message!),
_ => UnknownUpdateHandlerAsync(botClient, update)
};
try
{
await handler;
}
catch (Exception exception)
{
await HandleErrorAsync(botClient, exception, cancellationToken);
}
}
private static async Task BotOnMessageReceived(ITelegramBotClient botClient, Message message)
{
Console.WriteLine($"Receive message type: {message.Type}");
if (message.Type == MessageType.Contact && message.Contact != null)
{
// TODO: save the number...
Console.WriteLine($"Phone number: {message.Contact.PhoneNumber}");
}
if (message.Type != MessageType.Text)
return;
var action = message.Text!.Split(' ')[0] switch
{
"/myNumber" => RequestContactAndLocation(botClient, message),
_ => Usage(botClient, message)
};
Message sentMessage = await action;
Console.WriteLine($"The message was sent with id: {sentMessage.MessageId}");
static async Task<Message> RequestContactAndLocation(ITelegramBotClient botClient, Message message)
{
ReplyKeyboardMarkup requestReplyKeyboard = new(
new[]
{
// KeyboardButton.WithRequestLocation("Location"), // this for the location if you need it
KeyboardButton.WithRequestContact("Send my phone Number"),
});
return await botClient.SendTextMessageAsync(chatId: message.Chat.Id,
text: "Could you please send your phone number?",
replyMarkup: requestReplyKeyboard);
}
static async Task<Message> Usage(ITelegramBotClient botClient, Message message)
{
const string usage = "/myNumber - to send your phone number";
return await botClient.SendTextMessageAsync(chatId: message.Chat.Id,
text: usage,
replyMarkup: new ReplyKeyboardRemove());
}
}
private static Task UnknownUpdateHandlerAsync(ITelegramBotClient botClient, Update update)
{
Console.WriteLine($"Unknown update type: {update.Type}");
return Task.CompletedTask;
}
}
