Root Cause

The view is trying to parse request.body as JSON but the request body is empty or not valid JSON.

generic

中文

视图尝试将request.body解析为JSON，但请求体为空或不是有效的JSON。

Workarounds

  1. 95% success 
    Check if request.body is empty before parsing: if not request.body: return JsonResponse({'error': 'Empty body'}, status=400)
  2. 90% success 
    Wrap json.loads in try-except and return 400 with error message.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Hides the actual error and makes debugging difficult; still fails for malformed input.

  2. 90% fail

    request.POST only parses form data, not JSON payloads, so it will be empty.
