如何使用Python的Instabot库向同一用户发送多条消息？

以下是针对该问题的几种有效解决方案：

1. 清理文本中的换行符 #

readlines()读取的每行末尾会保留\n换行符，可能导致instabot处理消息时出错。先过滤掉换行符和空行：

with open("rawtext.txt", encoding="utf8") as f:
    # 去除每行首尾空白，同时过滤空行
    lines = [line.strip() for line in f if line.strip()]
for line in lines:
    bot.send_messages(line, ["REDACTED_USER"])

2. 重置Bot的API会话状态 #

instabot在发送一次消息后，会话状态可能出现异常，导致后续请求无法正常执行。每次发送后重置API状态：

with open("rawtext.txt", encoding="utf8") as f:
    lines = [line.strip() for line in f if line.strip()]
for line in lines:
    bot.send_messages(line, ["REDACTED_USER"])
    bot.api.reset()  # 重置API会话，恢复初始状态

3. 添加请求延迟避免触发限制 #

Instagram对请求频率有严格的反爬限制，短时间内连续发送消息会被拦截。添加延迟降低请求频率：

import time

with open("rawtext.txt", encoding="utf8") as f:
    lines = [line.strip() for line in f if line.strip()]
for line in lines:
    bot.send_messages(line, ["REDACTED_USER"])
    time.sleep(5)  # 每次发送后等待5秒，可根据情况调整时长
    bot.api.reset()

4. 改用单用户消息接口 #

send_messages原本是用于给多个用户批量发送同一条消息的接口，针对单个用户多次发送，改用send_message方法更合适：

import time

with open("rawtext.txt", encoding="utf8") as f:
    lines = [line.strip() for line in f if line.strip()]
for line in lines:
    bot.send_message(line, "REDACTED_USER")  # 参数顺序为消息内容、用户名
    time.sleep(5)
    bot.api.reset()

5. 异常捕获与重试机制 #

添加异常处理，针对发送失败的情况自动重试，提升稳定性：

import time
from instabot import Bot

bot = Bot()
bot.login(username="你的用户名", password="你的密码")

with open("rawtext.txt", encoding="utf8") as f:
    lines = [line.strip() for line in f if line.strip()]

for line in lines:
    success = False
    retry_times = 3
    while not success and retry_times > 0:
        try:
            bot.send_message(line, "REDACTED_USER")
            success = True
        except Exception as e:
            print(f"发送失败：{e}，剩余重试次数：{retry_times-1}")
            retry_times -= 1
            time.sleep(10)
            bot.api.reset()
    time.sleep(5)
