Question

我有一个json文件，如下所示：

        {"_id":"id1","cat":["C","D","R","P"],"desc":"some desc","name":"some_name","category":"categ","languages":["en"],"type":"swf","start_date":1.39958850681748E9},

    {"_id":"toy-driver","cat":["C","D","R","P"],"desc":"some desc","name":"name2","category":"Rac","languages":["en"],"type":"swf","start_date":1.399588506820609E9},
............

它包含大约900行。当我碰巧使用命令导入2或3个相似的行时：

mongoimport -d test -c test --jsonArray file.json

它完美导入没有任何错误，而导入整个文件会导致一些错误。

imported 0 objects
encountered 1 error

Answer 1

如果我没弄错的话，这里有两个问题。

--jsonArray需要1个JSON文档，其中所有900条记录都是单个数组的一部分您从一个文件中提供了900个独立的JSON行，这些行没有回答--jsonArray格式。（另外，在每行末尾放下逗号，mongoimport期待换行符。
如果要从文件导入数据，则必须指定关键字--file file.json

我相信如果您删除了--jsonArray参数并添加了--file关键字，那就没问题了。例如： -

mongoimport -d test -c test --file file.json

file.json与此类似：

{"_id":"id1","cat":["C","D","R"], ... "type":"swf","start_date":1.39958850681748E9}
{"_id":"id2","cat":["C","D","R"], ... "type":"swf","start_date":1.39958850681748E9}
{"_id":"id3","cat":["C","D","R"], ... "type":"swf","start_date":1.39958850681748E9}

希望这有帮助！
