Return the value at path in JSON serialized form

Examples

Required arguments

<details open><summary><code>key</code></summary>

is key to parse.

</details>

Optional arguments

<details open><summary><code>path</code></summary>

is JSONPath to specify. Default is root $. JSON.GET accepts multiple path arguments.

{{% alert title="Note" color="warning" %}}

When using a single JSONPath, the root of the matching values is a JSON string with a top-level array of serialized JSON value. In contrast, a legacy path returns a single value.

When using multiple JSONPath arguments, the root of the matching values is a JSON string with a top-level object, with each object value being a top-level array of serialized JSON value. In contrast, if all paths are legacy paths, each object value is a single serialized JSON value. If there are multiple paths that include both legacy path and JSONPath, the returned value conforms to the JSONPath version (an array of values).

{{% /alert %}}

</details> <details open><summary><code>INDENT</code></summary>

sets the indentation string for nested levels.

</details> <details open><summary><code>NEWLINE</code></summary>

sets the string that's printed at the end of each line.

</details> <details open><summary><code>SPACE</code></summary>

sets the string that's put between a key and a value.

</details>

Produce pretty-formatted JSON with redis-cli by following this example:

{{< highlight bash >}} ~/$ redis-cli --raw redis> JSON.GET myjsonkey INDENT "\t" NEWLINE "\n" SPACE " " path.to.value[1] {{< / highlight >}}

Examples

<details open> <summary><b>Return the value at <code>path</code> in JSON serialized form</b></summary>

Create a JSON document.

{{< highlight bash >}} redis> JSON.SET doc $ '{"a":2, "b": 3, "nested": {"a": 4, "b": null}}' OK {{< / highlight >}}

With a single JSONPath (JSON array bulk string):

{{< highlight bash >}} redis> JSON.GET doc $..b "[3,null]" {{< / highlight >}}

Using multiple paths with at least one JSONPath returns a JSON string with a top-level object with an array of JSON values per path:

{{< highlight bash >}} redis> JSON.GET doc ..a $..b "{"$..b":[3,null],"..a":[2,4]}" {{< / highlight >}}

</details>

Return information

{{< multitabs id="json-get-return-info" tab1="RESP2" tab2="RESP3" >}}

[Bulk string reply]({{< relref "/develop/reference/protocol-spec#bulk-strings" >}}): a JSON-encoded string representing the value(s) at the specified path(s).

With a single path, returns the JSON serialization of the value at that path. With multiple paths, returns a JSON object where each key is a path and each value is an array of JSON serializations.

-tab-sep-

[Bulk string reply]({{< relref "/develop/reference/protocol-spec#bulk-strings" >}}): a JSON-encoded string with a top-level array containing the value(s) at the specified path(s).

With a single path using $ (default in RESP3), returns a JSON array containing the serialized value. With multiple paths, returns a JSON object where each key is a path and each value is an array of JSON serializations.
