mongosh 方法

本页面提供 mongosh 方法的相关信息。这不是特定于语言的驱动程序（例如 Node.js）的文档。

如需了解 MongoDB API 驱动程序，请参阅特定语言的 MongoDB 驱动程序文档。

配置游标，以易于阅读的格式显示结果。

pretty() 方法具有以下原型形式：

db.collection.find(<query>).pretty()

行为

pretty() 方法：

不改变 mongosh 中的输出格式。
更改旧版mongo shell中的输出格式。

示例

请考虑以下文档：

db.books.save({
    "_id" : ObjectId("54f612b6029b47909a90ce8d"),
    "title" : "A Tale of Two Cities",
    "text" : "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...",
    "authorship" : "Charles Dickens"})

默认情况下，db.collection.find() 以密集格式返回数据：

db.books.find()
{ "_id" : ObjectId("54f612b6029b47909a90ce8d"), "title" : "A Tale of Two Cities", "text" : "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...", "authorship" : "Charles Dickens" }

使用 cursor.pretty() 可以设置游标，保证以更易于阅读的格式返回数据：

db.books.find().pretty()
{
    "_id" : ObjectId("54f612b6029b47909a90ce8d"),
    "title" : "A Tale of Two Cities",
    "text" : "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...",
    "authorship" : "Charles Dickens"
}
