我的流星应用程序不下载以前存储的文件。

最初我以为我遇到了 ongoworks:CollectionFS 的安全支持问题。

RsrchDocs.files.permit(['download']).apply() 导致 Invalid key 错误。已多次阅读 ongoworks:security 文档和 CollectionFS 文档，但没有发现我的错误。“ongoworks:security issues 4, 17, 20 的 Github 存储库似乎解决了这个问题。目前尚不清楚所提出的问题是否已经完全解决。我尝试了这些建议但没有成功。因为 RsrchDocs.allow({... }) （选项 B）允许服务器（重新）启动而没有错误我可能（可能？）有另一个错误阻止下载。

使用选项 A 或 B 时，将鼠标悬停在浏览器中的下载链接上会显示正确的 URL，但单击该链接不会启动下载。手动将 URL 复制到地址字段中并提交成功下载文档。

我应该在我的流星应用程序中做什么/更改才能成功下载以前存储的文档？

服务器/security.js

RsrchDocs.files.permit(['insert', 'update', 'remove']).apply();

// Option A:
// Uncommented causes "(STDERR) Error: EBADF, read" on (re)start
// Document download is NOT permitted.
//Security.permit(['download']).collections([RsrchDocs]).apply();

// Option B:
// Uncommented (re)starts without any error message
// Document download is NOT permitted 
//RsrchDocs.allow({
//    download: function(userId, doc){
//        return true;
//    }
//});

// Option C:
// Uncommented (re)starting meteor causes multiline error message
// Server start fails
//RsrchDocs.files.permit(['download']).apply();

// The error messages:
[[[[[ C:\Users\loco\My Projects\Meteor\research ]]]]]
