Telegram机器人无法发送消息至群组的问题求助

操作背景 #

• 通过BotFather创建机器人并创建Telegram群组
• 将机器人添加至目标群组
• 在BotFather的机器人设置中关闭Privacy Mode并允许群组使用

初始代码及问题 #

初始代码：

import requests
bot_id = '261600102:AAGx**************uRljA'
chat_id = '27*****'
#chat_id = "MyPythonTesting"
message = input('ENTER THE MESSAGE:     ')
url = f"https://api.telegram.org/bot{bot_id}/sendmessage?chat_id={chat_id}&test={message}"
url = f"https://core.telegram.org/bot{bot_id}/sendmessage?chat_id={chat_id}&test={message}"
response = requests.get(url)
print(response)

运行情况：

• 第一个URL触发ConnectionError，报错信息：

raise ConnectionError(e, request=request)
requests.exceptions.ConnectionError: HTTPSConnectionPool(host='api.telegram.org', port=443): Max retries exceeded with 
url: /bot261600102:AAG********7uRljA/sendmessage?chat_id=276******&test=esae (Caused by NameResolutionError("<urllib3.connection.HTTPSConnection object at 0x000001AC0425F910>: Failed to resolve 'api.telegram.org' ([Errno 11001] getaddrinfo failed)"))

• 第二个URL返回状态码200，但消息未发送至群组

修改后代码及新错误 #

修改后代码：

import requests
bot_id = '261600102:AAGx**********YHCCeXV6VqD67uRljA'
chat_id = "MyPythonTesting"
message = input('ENTER THE MESSAGE:     ')
url = f"https://api.telegram.org/bot{bot_id}/sendmessage?chat_id={chat_id}&text={message}"
response = requests.get(url)
print(response)

触发ConnectionError，完整报错栈：

解决方案建议 #

1. 解决域名解析/网络访问问题 #

报错getaddrinfo failed说明无法解析api.telegram.org域名，或无法建立网络连接：

• 先在终端执行ping api.telegram.org，或用浏览器访问https://api.telegram.org，确认网络是否能正常访问该地址
• 若处于受限网络环境，需为requests配置代理：

import requests
bot_id = '你的机器人ID'
chat_id = '群组数字ID'
message = input('ENTER THE MESSAGE:     ')
url = f"https://api.telegram.org/bot{bot_id}/sendmessage?chat_id={chat_id}&text={message}"
# 配置代理，替换为你的代理地址和端口
proxies = {
    'https': 'http://your-proxy-address:port'
}
response = requests.get(url, proxies=proxies)
print(response.text)  # 打印响应内容，便于排查错误

2. 修正API地址与请求参数 #

• 必须使用https://api.telegram.org作为API域名，core.telegram.org是官方文档地址，无法处理API请求
• 请求参数中消息内容的键是text，而非初始代码中的test，修改后的代码已修正此问题

3. 确认Chat ID正确性 #

• 群组名称（如MyPythonTesting）无法直接作为chat_id使用，需获取群组的数字ID：
  • 在群组内发送一条消息，然后调用https://api.telegram.org/bot<你的机器人ID>/getUpdates接口，查看返回的JSON数据中的chat.id字段
  • 或使用Telegram机器人@getidsbot，将其加入群组后获取群组ID

4. 检查机器人权限 #

确保机器人在群组内拥有发送消息的权限，可在群组设置中确认机器人的权限为"发送消息"
