如何在MongoDB脚本中打印以控制台对象？

您可以使用printjson()方法来打印以在MongoDB脚本中控制台对象。语法如下-

printjson({yourFieldName”:yourValue”,........N});

您可以将JSON.stringify()与print()函数一起使用。语法如下：

print ( JSON.stringify( { {yourFieldName”:yourValue”,........N} } ));

让我们实现以上语法以在Mongo脚本中打印对象。查询如下-

>printjson({"UserId":101,"UserName":"John","UserCoreSuject":["Java","MongoDB","MySQL","SQL Server"]});

以下是输出-

{
   "UserId" : 101,
   "UserName" : "John",
   "UserCoreSuject" : [
      "Java",
      "MongoDB",
      "MySQL",
      "SQL Server"
   ]
}

您可以使用另一个查询-

> print ( JSON.stringify( {"UserId":101,"UserName":"John","UserCoreSuject":["Java","MongoDB","MySQL","SQL Server"]} ));

以下是输出-

{"UserId":101,"UserName":"John","UserCoreSuject":["Java","MongoDB","MySQL","SQL Server"]}
