Question

我有一个JSON文件（来自Mongo大学），里面有一些JSON

但是，当我运行导入时：

PS C:\Program Files\MongoDB\Server\3.0\bin> .\mongoimport.exe -d blog -c posts --drop posts.json

我收到错误，没有导入任何内容：

发生了什么事？

我用3.0和3.2尝试过它。

Answer 1

根据https://jira.mongodb.org/browse/TOOLS-939，有一个错误会影响某些版本的mongoimport和mongorestore导致mongoimport命令失败。

要解决此问题，您可以将--batchSize选项与参数1一起使用。

使用此改革后的查询：

mongoimport -d blog -c posts < posts.json --batchSize 1

希望这会奏效。

Answer 2

尝试使用-j或--numInsertionWorkers标志。某些版本存在一些问题，并且过去创建了故障单。 https://jira.mongodb.org/plugins/servlet/mobile#issue/TOOLS-939

/*demo*/
div {
  display:flex;
  align-items:center;
  justify-content:center;/* center content not text */
  text-align:center; 
  }

Answer 3

尝试以下格式

mongoimport posts.json -d blog -c posts --drop --jsonArray

Answer 4

要将json文件导入您当前正在使用的mongoDB batabase，请按照以下步骤操作。

转到您的the link，然后选择当前使用的群集。
点击收藏，然后转到命令行工具。
您可以在那看到数据导入和导出工具，其中提供了将json文件导入到数据库的命令。
按照命令中的指示替换标签。

如果出现任何错误，例如：

Failed: cannot decode array into a D

然后在命令的最后添加--jsonArray。 示例：

mongoimport --host <hostname> --ssl --username <username> --password <PASSWORD> --authenticationDatabase admin --db <DATABASE> --collection <COLLECTION> --file <FILENAME> --jsonArray

无法将json文件导入Mongo
