Root Cause

The URL passed to aiohttp request is malformed or empty, such as missing host or scheme.

generic

中文

传递给 aiohttp 请求的 URL 格式错误或为空，例如缺少主机或协议。

Workarounds

  1. 95% success Validate and construct URL using yarl.URL 
    from yarl import URL; url = URL('http://example.com')
  2. 85% success Use urllib.parse to sanitize the URL 
    from urllib.parse import urlparse; parsed = urlparse(url); if not parsed.scheme: url = 'http://' + url

Dead Ends

Common approaches that don't work:

  1. Adding extra slashes to the URL 50% fail

    Malformed URLs are not fixed by adding slashes; proper validation is needed.

  2. Using a relative URL without base 80% fail

    aiohttp requires absolute URLs; relative paths cause InvalidURL.
