generic

解决方案

  1. 70% 成功率 
    Set a custom limit in uvicorn: uvicorn.run(app, limit_max_request_size=1000000) for 1MB
  2. 90% 成功率 
    Use a middleware to check content-length and reject early with a custom message

无效尝试

常见但无效的做法:

  1. 80% 失败

    Uvicorn doesn't have a direct setting; you need to configure the ASGI server or use a middleware.

  2. 50% 失败

    This handles the error but doesn't allow the upload; you need to increase the limit.
