如何使用mongoimport导入json文件 [英] how to use mongoimport to import a json file

问题描述

我正在尝试使用mongoimport通过以下命令行导入json文件:

I'm trying to import a json file using mongoimport with this command line:

mongoimport --db posts --collection rows --file post_history.json

但它返回此错误:

connected to: localhost
Failed: error processing document #1: invalid character 'N' after object key:value pair
imported 0 documents

文件内容如下:

 },

我想念什么?这是正确的命令吗?谢谢！

What am I missing? Is it the right command? Thanks!

更新1 :
正如CodeBird所建议的那样，我已经尝试了以下命令:

UPDATE 1:
As CodeBird suggested I've tried this command:

mongoimport --db posts --collection rows --type json --file post_history.json --jsonArray

它返回此:

connected to: localhost
Failed: error processing document #18875: invalid character 'N' after object key:value pair
imported 10000 documents

推荐答案

您应该使用此命令告诉mongo它是一个json数组

You should use this command to tell mongo it is a json array

mongoimport --db posts --collection rows --file post_history.json --jsonArray

我复制了您的json，并进行了测试:

I copied your json, and tested:

mongoimport --db posts --collection rows --file test.json --jsonArray

2016-01-19T06:18:57.906-0600    imported 5 documents

编辑

在更新问题之后，我认为您可能还应该为mongo固定一些特殊字符，例如:

Following your question update, I think you might also have some special characters that should be fixed for mongo for example:

tab = \t
" = \"
\ = \\
