解决方案
-
90% 成功率
Configure the server limit, e.g., in Uvicorn: uvicorn app:app --limit-max-request-size 10485760
-
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:
-
80% 失败
Reading the entire file into memory before checking size can cause memory issues.
-
60% 失败
Increasing the limit globally may affect other parts of the app.
