根因分析
上传文件超过服务器或反向代理的请求体大小限制(如 nginx client_max_body_size)。
English
The uploaded file exceeds the server or reverse proxy body size limit (e.g. nginx client_max_body_size).
解决方案
-
92% 成功率
client_max_body_size 50m;
-
85% 成功率
async for chunk in request.stream(): await save_chunk(chunk)
无效尝试
常见但无效的做法:
-
90% 失败
FastAPI has no built-in limit; the block is at nginx/gunicorn.
-
85% 失败
Same payload will always exceed the limit.
