解决方案

  1. 95% 成功率 
    writer = aiohttp.MultipartWriter(); part = payload; writer.append(part); await session.post(url, data=writer)
  2. 85% 成功率 
    headers = {'Content-Type': 'multipart/form-data; boundary=myboundary'}; data = '--myboundary...'

无效尝试

常见但无效的做法:

  1. 70% 失败

    If the server expects a specific boundary, it won't match.

  2. 90% 失败

    The data cannot be parsed, leading to incomplete processing.
