使用nginx/puma下载的Rails 5.2.1 ActiveStorage文件被截断

我的第一个ActiveStorage项目在开发（仅限puma）上运行良好，但在生产（nginx/puma）上，我遇到了下载显示为截断文件的大文件的问题

例如，一个大小为24.1MB的上传文件的下载量为5MB（截断）

我主要上传pdf文件，上传的文件是完整的（在服务器上检查）&预览效果很好

所有环境都使用

config.active\u storage.service=：local

config/storage.yml Rails配置/puma.rb

---

使用

proxy\uhttp\uversion1.1

默认情况下，nginx使用http1.0进行代理，代理不支持分块传输编码

谢谢@amiuhle，这解决了我的问题。
