使用类似JSON的结构遍历Julia中的嵌套字典

# 定义一个嵌套字典
dict = Dict(
    "key1" => "value1",
    "key2" => Dict(
        "key21" => "value21",
        "key22" => Dict(
            "key221" => "value221",
            "key222" => "value222"
        )
    ),
    "key3" => "value3"
)

# 定义一个递归函数，遍历嵌套字典
function traverse_dict(dict::Dict)
    for (key, value) in dict
        if typeof(value) == Dict
            # 如果值是字典，递归调用自身遍历子字典
            traverse_dict(value)
        else
            # 如果值是其他类型，则进行相应的操作
            println("Key: $key, Value: $value")
        end
    end
end

# 调用遍历函数
traverse_dict(dict)
