使用 xlsx 库以 angular 形式下载大型 excel 文件（net::ERR_INCOMPLETE_CHUNKED_ENCODING 200）

Question

我正在使用 angular + springboot 下载 excel 文件，api 返回 application/json 文件。transfer-encoding:chunked 始终处于启用状态，我看到响应返回 http 1.1。

我在 stackoverflow 上发布了这个问题，但还没有得到任何解决方案。请帮忙，因为我已经困惑了好久，不知道该怎么办了。

错误是 polyfills.35a5ca1855eb057f016a.js:1 POSThttps://fff.com///RETRIEVE_ALL_BLOCKSnet::ERR_INCOMPLETE_CHUNKED_ENCODING 200 nginx.conf 文件
