Description

JsonDocument::getMember() gets the value associated with the specified key; it reproduces JsonObject::getMember().

Unlike JsonDocument::getOrCreateMember(), this function doesn’t add a new key in the object; instead, it returns null.

Instead of this function, you can use JsonDocument::operator[] which offers a more intuitive syntax.

Signatures

Arguments

key: the key of the value in the object.

Return value

JsonDocument::getMember() returns a JsonVariant that points to the requested value.

JsonDocument::getMember() return null when no match is found.
