  • 配置光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()

Examples

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" }

通过使用cursor.pretty()，您可以将光标设置为以人类易于解析的格式返回数据：

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"
}
