推荐答案

虽然我不建议在Mongo中存储大文件,尽管有可能,较小的文件会更好.

While I don't recommend storing big files in Mongo, though it's possible, smaller files would be better.

仅读取文件的文本(如果是文本文件)或二进制文件(如果文件为二进制格式,即可执行文件).您可以使用fs库读取文件并进行相应的编码.

Simply read the file's text (if it's a text file), or binary (if it's in a binary format i.e executable). You can use the fs library to read the file and encode it accordingly.

然后将存储在变量中的数据插入数据库内部.

Then insert the data, stored in a variable, inside the database.

var fs = require('fs');

// Read file with proper encoding...
var data = //...

// Insert into Mongo
mongo.insert({file: data});

当您要从数据库中检索文件时,请执行相反的操作.根据文件类型的不同,编码/解码的过程也不同.

When you want to retrieve the file from the database, you'd do the opposite. The process of encoding/decoding is different depending on the type of file.
