MongoDB error processing document #2: invalid character ',' looking for beginning of value

打算把公司登陸系統現在還是直接使用數據庫進行查詢，今天打算把它優化一下換成 MongoDB 進行查詢，結果導入測試數據的時候一直報  Failed: error processing document #2: invalid character ',' looking for beginning of value  錯誤，搞了大半天才解決，它喵的。

[root@iZm5ec7pkk6xphure3pgf5Z bin]# ./mongoimport -h localhost:9085 -c gm_users -d api --mode upsert --file gm_user1.json 
2019-04-08T15:52:52.307+0800	connected to: localhost:9085
2019-04-08T15:52:52.307+0800	Failed: error processing document #2: invalid character ',' looking for beginning of value
2019-04-08T15:52:52.307+0800	imported 0 documents

提示我逗號？？一看我這個沒問題，也是JSON格式呀，懵逼的一瞥。

{
	"user_id": "脫敏",
	"account": "脫敏",
	"password": "脫敏",
	"phone": "脫敏",
	"lock_status": "脫敏"
},
{
	"user_id": "脫敏脫敏",
	"account": "脫敏",
	"password": "脫敏",
	"phone": "脫敏",
	"lock_status": "脫敏"
}

然後我再 stackoverflow 看到可以使用 -vvvvv 確定報錯的位置。

[root@iZm5ec7pkk6xphure3pgf5Z bin]# ./mongoimport -h localhost:9085 -c gm_users -d api --mode upsert --file gm_user1.json -vvvvv

嗯，還是這個問題。而且我這個應該是第一個json就出問題了！

 

最後，找遍了百度，官方文檔（可能是我遺漏了）沒找到，最後的最後，忘記是在哪看到的了，就是因爲這個 ， （逗號）的問題，它喵的，有了它就會報錯，然後用 UE 把這些 ，（逗號）刪除了（我是因爲數據量小才用的UE ，數據量大別用這玩意）

{
	"user_id": "脫敏",
	"account": "脫敏",
	"password": "脫敏",
	"phone": "脫敏",
	"lock_status": "脫敏"
},  《-------------------------------就是因爲這個逗號
{
	"user_id": "脫敏脫敏",
	"account": "脫敏",
	"password": "脫敏",
	"phone": "脫敏",
	"lock_status": "脫敏"
}

吶，變成這樣子就歐拉！！

{
	"user_id": "脫敏",
	"account": "脫敏",
	"password": "脫敏",
	"phone": "脫敏",
	"lock_status": "脫敏"
}
{
	"user_id": "脫敏脫敏",
	"account": "脫敏",
	"password": "脫敏",
	"phone": "脫敏",
	"lock_status": "脫敏"
}

然後再使用導入腳本執行一下

[root@iZm5ec7pkk6xphure3pgf5Z bin]# ./mongoimport -h localhost:9085 -c gm_users -d api --mode upsert --file gm_user1.json 
2019-04-08T16:15:31.715+0800	connected to: localhost:9085
2019-04-08T16:15:31.767+0800	imported 576 documents

歐拉，導出成功拉，它喵的。
