如何将 bson 和 json 文件导入 MongoDB？

Question

我关注了来自https://github.com/Apress/def-guide-to-mongodb/tree/master/9781484211830/The%20Definitive%20Guide%20to%20MongoDB 的bson 和json 文件

$ ls .
aggregation.bson  aggregation.metadata.json  mapreduce.bson  mapreduce.metadata.json  storage.bson  text.json

如何将它们导入 MongoDB？

我尝试将它们中的每一个都作为一个集合导入，但失败了：

$ mongorestore -d test -c aggregation 
2018-07-18T01:44:25.376-0400    the --db and --collection args should only be used when restoring from a BSON file. Other uses are deprecated and will not exist in the future; use --nsInclude instead
2018-07-18T01:44:25.377-0400    using default 'dump' directory
2018-07-18T01:44:25.377-0400    see mongorestore --help for usage information
2018-07-18T01:44:25.377-0400    Failed: mongorestore target 'dump' invalid: stat dump: no such file or directory

我不确定我是否正确指定了文件aggregation.bson，但上面的命令是我从书中类似示例中学到的。

谢谢。

下面，为什么第一个失败，第二个成功？我应该使用哪个命令？

$ mongoimport -d test -c aggregation --file aggregation.bson 
2018-07-18T09:45:44.698-0400    connected to: localhost
2018-07-18T09:45:44.720-0400    Failed: error processing document #1: invalid character 'º' looking for beginning of value
2018-07-18T09:45:44.720-0400    imported 0 documents

$ mongoimport -d test -c aggregation --file aggregation.metadata.json 
2018-07-18T09:46:05.058-0400    connected to: localhost
2018-07-18T09:46:05.313-0400    imported 1 document

Answer 1

mongoimport --db dbName --collection collectionName --type json --file fileName.json

更新：

C:\Program Files\MongoDB\Server\4.0\bin>mongorestore -d test -c aggregation aggregation.bson

所以我尝试了它，它对我来说很好，你的 bin 文件夹中有文件还是你使用的命令不完整？

db.aggregation.find().pretty().limit(2)

        ]
}
