mongosh 方法

This page documents a mongosh method. This is not the documentation for a language-specific driver, such as Node.js.

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。

The pretty() method has the following prototype form:

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

行为

The pretty() method:

Does not change the output format in mongosh.
更改旧版 mongo shell 中的输出格式。

示例

请考虑以下文档：

db.books.insertOne({
    "_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" }

By using cursor.pretty() you can set the cursor to return data in a format that is easier to read:

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"
}
