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"]}
