如何将JSON文件读入可以查询的MongoDB集合？

我有一个包含数百个JSON文件的文件夹。 每个文件本质上都是一条记录——一个包含个人详细信息的JSON对象。 下面是三个文件的示例：

record1.json

{
        "_id" : ObjectId("609d1ce7ca3840259eed1da5"),
        "first_name" : "Abdulrahman",
        "nationality" : "dz"
}

{
        "_id" : ObjectId("609d1df5ca3840259eed1da6"),
        "first_name" : "Tony",
        "nicknames" : [
                "Biggus Dickus",
                "Tarzan",
                "Mogli",
                "King of the Jungle"
        ],
        "age" : 21
}

{
        "_id" : ObjectId("609d20fd8bc03bb4492cd24a"),
        "first_name" : "Mary",
        "last_name" : "Jane",
        "age" : 19,
        "gender" : "f"
}

record2.json

{
        "_id" : ObjectId("609d1ce7ca3840259eed1da5"),
        "first_name" : "Abdulrahman",
        "nationality" : "dz"
}

{
        "_id" : ObjectId("609d1df5ca3840259eed1da6"),
        "first_name" : "Tony",
        "nicknames" : [
                "Biggus Dickus",
                "Tarzan",
                "Mogli",
                "King of the Jungle"
        ],
        "age" : 21
}

{
        "_id" : ObjectId("609d20fd8bc03bb4492cd24a"),
        "first_name" : "Mary",
        "last_name" : "Jane",
        "age" : 19,
        "gender" : "f"
}

record3.json

{
        "_id" : ObjectId("609d1ce7ca3840259eed1da5"),
        "first_name" : "Abdulrahman",
        "nationality" : "dz"
}

{
        "_id" : ObjectId("609d1df5ca3840259eed1da6"),
        "first_name" : "Tony",
        "nicknames" : [
                "Biggus Dickus",
                "Tarzan",
                "Mogli",
                "King of the Jungle"
        ],
        "age" : 21
}

{
        "_id" : ObjectId("609d20fd8bc03bb4492cd24a"),
        "first_name" : "Mary",
        "last_name" : "Jane",
        "age" : 19,
        "gender" : "f"
}

如何将所有这些文件收集到MongoDB集合中，该集合可以从MongoShell内部查询？我希望能够执行诸如db.contacts.find（）.pretty（）之类的命令

另外，命名每个文件的最佳做法是什么？

是您的朋友，因为您有多个JSON文件，您可能希望将所有JSON数据合并到一个文件（或JSON数组）中并进行导入。另一种选择是，您还可以使用编程语言（编写自己的程序）将数据导入MongoDB数据库。
