JSON
Redis的JSON支持
Redis Stack 的 JSON 功能为 Redis 提供了 JavaScript 对象表示法（JSON）支持。它允许您在 Redis 数据库中存储、更新和检索 JSON 值，类似于任何其他 Redis 数据类型。Redis JSON 还可以与 Redis 查询引擎无缝协作，让您能够 索引和查询 JSON 文档。
主要功能
- 全面支持JSON标准
- 用于选择/更新文档内部元素的JSONPath语法（参见JSONPath语法）
- 文档以二进制数据的形式存储在树结构中，允许快速访问子元素
- 为所有JSON值类型提供类型化原子操作
使用 Redis 与 JSON
第一个尝试的JSON命令是JSON.SET，它用一个JSON值设置一个Redis键。JSON.SET接受所有JSON值类型。这个例子创建了一个JSON字符串：
> JSON.SET bike $ '"Hyperion"'
OK
> JSON.GET bike $
"[\"Hyperion\"]"
> JSON.TYPE bike $
1) "string"Are you tired of using redis-cli? Try Redis Insight - the developer GUI for Redis.

> JSON.SET newbike $ '["Deimos", {"crashes": 0}, null]'
OK
> JSON.GET newbike $
"[[\"Deimos\",{\"crashes\":0},null]]"
> JSON.GET newbike $[1].crashes
"[0]"
> JSON.DEL newbike $[-1]
(integer) 1
> JSON.GET newbike $
"[[\"Deimos\",{\"crashes\":0}]]"Are you tired of using redis-cli? Try Redis Insight - the developer GUI for Redis.

格式化CLI输出
CLI 有一个原始输出模式，允许您为来自 JSON.GET 的输出添加格式，使其更易读。要使用此功能，请使用 --raw 选项运行 redis-cli，并在 JSON.GET 中包含诸如 INDENT、NEWLINE 和 SPACE 等格式化关键字：
$ redis-cli --raw
> JSON.GET obj INDENT "\t" NEWLINE "\n" SPACE " " $

"loggedOut": true
}
]
启用 Redis JSON
Redis JSON 在基本的 Redis 服务器中默认不可用，因此您应该安装 Redis Stack 或 Redis Enterprise，这两者都包含 JSON 和其他有用的模块。请参阅安装 Redis Stack 或 安装 Redis Enterprise 获取完整的安装说明。
限制
传递给命令的JSON值的深度最多可达128。如果您传递给命令的JSON值包含嵌套级别超过128的对象或数组，命令将返回错误。
