使用 JSON 进行 mongoimport

zipcodes.json 中的示例 zipcode 数据集存储在 c：\ Users \ yc03ak1 \ Desktop \ zips.json 中

{ "_id" : "01001", "city" : "AGAWAM", "loc" : [ -72.622739, 42.070206 ], "pop" : 15338, "state" : "MA" }
{ "_id" : "01002", "city" : "CUSHMAN", "loc" : [ -72.51564999999999, 42.377017 ], "pop" : 36963, "state" : "MA" }
{ "_id" : "01005", "city" : "BARRE", "loc" : [ -72.10835400000001, 42.409698 ], "pop" : 4546, "state" : "MA" }
{ "_id" : "01007", "city" : "BELCHERTOWN", "loc" : [ -72.41095300000001, 42.275103 ], "pop" : 10579, "state" : "MA" }
{ "_id" : "01008", "city" : "BLANDFORD", "loc" : [ -72.936114, 42.182949 ], "pop" : 1240, "state" : "MA" }
{ "_id" : "01010", "city" : "BRIMFIELD", "loc" : [ -72.188455, 42.116543 ], "pop" : 3706, "state" : "MA" }
{ "_id" : "01011", "city" : "CHESTER", "loc" : [ -72.988761, 42.279421 ], "pop" : 1688, "state" : "MA" }

将此数据集导入名为 test 的数据库和名为 zips 的集合

C:\Users\yc03ak1>mongoimport --db test --collection "zips" --drop --type json --host "localhost:47019"  --file "c:\Users\yc03ak1\Desktop\zips.json"

• --db：要导入数据的数据库的名称
• --collection：数据库中要对数据进行压缩的集合的名称
• --drop：在导入之前先删除集合
• --type：需要导入的文档类型。默认 JSON
• --host：要导入数据的 mongodb 主机和端口。
• --file：json 文件所在的路径
