Root Cause

The form data is not properly encoded or the request body is not parsed correctly.

generic

中文

表单数据未正确编码或请求体解析不正确。

Workarounds

  1. 100% success 
    Use await request.form() correctly to parse the form data.
  2. 90% success 
    Ensure the client sends proper content-type: application/x-www-form-urlencoded or multipart/form-data.

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Some fields may be binary or multi-encoded, causing errors.

  2. 80% fail

    This is a common mistake; the method must be awaited.
