mongodb - mongoimport 期间出错

Question

我有几个有效的 JSON 文档，我尝试将它们导入 mongodb。

{ "Books":
  [{ "ISBN":"ISBN-0-13-713526-2",
  "Price":85,
  "Edition":3,
  "Title":"A First Course in Database Systems",
  "Authors":[ {"First_Name":"Jeffrey", "Last_Name":"Ullman"},
              {"First_Name":"Jennifer", "Last_Name":"Widom"} ] }
,
{ "ISBN":"ISBN-0-13-815504-6",
  "Price":100,
  "Remark":"Buy this book bundled with 'A First Course' - a great deal!",
  "Title":"Database Systems:The Complete Book",
  "Authors":[ {"First_Name":"Hector", "Last_Name":"Garcia-Molina"},
              {"First_Name":"Jeffrey", "Last_Name":"Ullman"},
              {"First_Name":"Jennifer", "Last_Name":"Widom"} ] }],
"Magazines":
[{ "Title":"National Geographic",
  "Month":"January",
  "Year":2009 }
,
{ "Title":"Newsweek",
  "Month":"February",
  "Year":2009 },
{"Title": "Newsweek"}]
}

我收到以下错误:

Sun Mar 24 15:23:27 exception:BSON representation of supplied JSON istoo large: Failure parsing JSON string near: "Month":"J Sun Mar 24

15:23:27 exception:BSON representation of supplied JSON is too large:Failure parsing JSON string near: "Year":200 Sun Mar 24 15:28:23

ERROR: encountered 28 errors

有人能说说怎么回事吗？

Answer 1

默认情况下，mongoimport 期望每个文档位于 JSON 文件的单行上。您需要使用您正在使用的格式将 --jsonArray 传递给 mongoimport，或者只需确保单个文档的所有数据都在一行上。

(我按原样保存了您的文件，添加了 --jsonArray, 选项并且效果很好。)
