Question

我创建了一个demodb.json文件（包含10个文档），并将其保存在我的系统的D:\驱动器中

demodb.json的内容是：

[{"ID": 1,"Name": "Kabul","CountryCode": "AFG","District": "Kabol","Population": 1780000}, {"ID": 2,"Name": "Qandahar","CountryCode": "AFG","District": "Qandahar","Population": 237500}, {"ID": 3,"Name": "Herat","CountryCode": "AFG","District": "Herat","Population": 186800}, {"ID": 4,"Name": "Mazar-e-Sharif","CountryCode": "AFG","District": "Balkh","Population": 127800}, {"ID": 5,"Name": "Amsterdam","CountryCode": "NLD","District": "Noord-Holland","Population": 731200}, {"ID": 6,"Name": "Rotterdam","CountryCode": "NLD","District": "Zuid-Holland","Population": 593321}, {"ID": 7,"Name": "Haag","CountryCode": "NLD","District": "Zuid-Holland","Population": 440900}, {"ID": 8,"Name": "Utrecht","CountryCode": "NLD","District": "Utrecht","Population": 234323}, {"ID": 9,"Name": "Eindhoven","CountryCode": "NLD","District": "Noord-Brabant","Population": 201843}, {"ID": 10,"Name": "Tilburg","CountryCode": "NLD","District": "Noord-Brabant","Population": 193238}]

我的Mongodb位置是：D:\SanMongoDB

我的所有数据库和馆藏都存储在D:\SanMongoDB\MongoData

中

demodb的内容 - ＆gt;城市集合如下

{  "_id":ObjectId("51892b40842d69f5fa21962f"),
   "Name": "India",
   "CountryCode": "IND",
   "District": "ODISHA",
   "Population": 2050000
}

我启动了Mongod服务器然后打开mongo客户端在mongo客户端，我做了以下事情：

使用demodb mongoimport -d demodb -c city --type json --file demodb.json --jsonarray

但我发现错误如下

Thu May 09 08:21:57.861 Javascript execution failed:SyntaxError:Unexpected identifier

请建议我需要做什么，这样我就可以轻松地将Json文件导入到现有的Mongodb数据库中。

Answer 1

假设你的东西在file.json中，试试sed -e 's/ID/_id/g;s/\([^:]*\):\([^,}]*\)/"\1":"\2"/g' file.json | mongoimport --collection collection-name。你可以得到sed for Windows from GNUWin32。如果您还有其他问题，请告诉我。

此处，s/ID/_id/g会在文件ID中用_id替换每个file.json，而第二个引用每个单词，以使您的文件valid JSON。在两次转换之后，mongoimport工作正常。

Answer 2

不是100％肯定，但我认为它应该是这样的：

启动mongod

使用demodb

mongoimport -d [dbname] -c [collectionname] --demodb.json --jsonarray
