根因分析

上传的文件超过服务器允许的最大大小,通常是由于Web服务器或框架的默认限制。

English

The uploaded file exceeds the server's maximum allowed size, often due to default limits in the web server or framework.

generic

解决方案

  1. 90% 成功率
    Configure the server limit, e.g., in Uvicorn: uvicorn app:app --limit-max-request-size 10485760
  2. 95% 成功率
    Check file size before processing: if file.size > MAX_SIZE:\n    raise HTTPException(413)

无效尝试

常见但无效的做法:

  1. 80% 失败

    Reading the entire file into memory before checking size can cause memory issues.

  2. 60% 失败

    Increasing the limit globally may affect other parts of the app.
