使用instagrapi发送Instagram私信遇403错误求助

我尝试使用instagrapi发送私信，参照文档编写了以下代码：

from instagrapi import Client

cl = Client()
cl.login(USERNAME, PASSWORD)

cl.direct_send("This is a message", ['53979279619', '54365742245', '51215837511', '53058609422', '54547827808'])

运行代码时出现如下错误：

requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: 

https://i.instagram.com/api/v1/direct_v2/threads/broadcast/text/

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "bot.py", line 67, in <module>
    main(file_name)
  File "bot.py", line 42, in main
    cl.direct_send(f"{message}", followers_id)
  File "C:\Users\HP\AppData\Local\Programs\Python\Python38-32\lib\site-packages\instagrapi\mixins\direct.py", line 254, in direct_send
    result = self.private_request(

    raise e

    self._send_private_request(endpoint, **kwargs)
  File "C:\Users\HP\AppData\Local\Programs\Python\Python38-32\lib\site-packages\instagrapi\mixins\private.py", line 326, in _send_private_request
    raise ClientForbiddenError(e, response=e.response, **last_json)

我确认账号未被封禁且处于活跃状态，但更换账号后仍出现相同错误，恳请协助解决该问题。

解决方法 #

• 检查目标用户隐私设置：错误提示提到可能和对方设置有关，部分用户可能开启了「仅接受已关注用户的私信」，而你的账号未关注这些目标用户，导致被拒绝。先确认是否已关注所有收件人，或者对方是否允许陌生人发私信。
• 模拟真实客户端环境：Instagram的反爬机制会识别非官方请求，初始化Client时添加设备模拟参数，同时处理可能的验证挑战：

  from instagrapi import Client
  from instagrapi.exceptions import ChallengeRequired
  from instagrapi.mixins.challenge import ChallengeChoice
  
  cl = Client()
  # 生成模拟设备信息，贴近真实客户端
  cl.set_device(cl.generate_device())
  try:
      cl.login(USERNAME, PASSWORD)
  except ChallengeRequired as e:
      # 处理验证挑战，选择短信或邮箱验证
      challenge = cl.challenge_resolve(e.challenge_url)
      if challenge["step_name"] == "select_verify_method":
          cl.challenge_select_verify_method(challenge, choice=ChallengeChoice.SMS)
          # 输入收到的验证码
          cl.challenge_send_security_code(input("请输入验证码: "))
          cl.login(USERNAME, PASSWORD)
  

• 控制发送频率与批量大小：Instagram限制短时间内的批量操作，拆分发送任务并添加间隔：

  import time
  
  followers_id = ['53979279619', '54365742245', '51215837511', '53058609422', '54547827808']
  for user_id in followers_id:
      cl.direct_send("This is a message", [user_id])
      time.sleep(10)  # 每次发送间隔10秒，可根据情况调整
  

• 更新instagrapi版本：旧版本库可能存在API适配问题，执行以下命令更新：

  pip install --upgrade instagrapi
  

• 确认账号私信功能正常：先在官方APP或网页端手动发送一条私信，确保账号本身的私信功能未被隐形限制，再用代码尝试。
