问题描述

我想知道知道手机号码是否已注册到 Telegram Messenger 的最佳方法是什么?

I was wondering about what is the best way to know if a cell phone number has registered to the Telegram messenger or not?

谢谢.

推荐答案

我不熟悉 python.但有一种方法可以做到这一点:

I'm not familiar with python. but there is a way to do this:

如您所知，您可以使用 phoneNumber 和 firsName 在电报机器人中发送联系人(不必是拥有联系人的真实姓名)那个数字).

As you know you can send a contact in telegram bot using its phoneNumber and a firsName (Doesn't need to be the real first name of the contact who owns that number).

将联系人发送到某个chatID(无论您选择什么chatID，都可以是您自己的个人聊天ID)后，您可以查找其UserID.

After sending the contact to a chatID(no matter what chatID you choose, can be your own personal chat ID), you can look for its UserID.

现在如果这个人存在于 Telegram 中，你会得到一个很长的数字代表他/她的用户 ID 或聊天 ID，但如果不是，则长度为 0.

Now if the person exists in Telegram you will get a long number that stands for his/her UserID or chatID but if not the long will be 0.

在 C# 中，我使用这段代码查看电报中是否存在电话号码，并且效果很好.

In C# I used this piece of code to see whether a phone number exists in telegram or not and it worked very well.

string s = "+44....";    //the phone number
var req2 = await bot.MakeRequestAsync(new SendContact(update.Message.Chat.Id, s, "Name"));
if(req2.Contact.UserId == 0)
{
   Console.WriteLine("The contact does not exist in Telegram");
}else
{
 Console.WriteLine("The contact exists in telegram with UserID:{0}",req2.Contact.UserId.ToString());
}
