args:

• key (string) —— 需要获取的Meta的key值
• default_prop (特定类型) —— 获取key值失败时的默认值

return:

特定类型的值

example:

    ...
    Status Open(const std::shared_ptr<Configuration> config):
        auto str = config->GetString("string", "default");
        auto strings = config->GetStrings("strings", {"test", "test"});
        auto int32 = config->GetInt32("int32", 1);
        auto int32s = config->GetInt32s("int32s", {1,2,3});
        ...
        MBLOG_INFO << str;
        for (auto &item: strings) {
            MBLOG_INFO << item
        }
        MBLOG_INFO << int32;
        for (auto &item: int32s) {
            MBLOG_INFO << item
        }

        return STATUS_OK;

result:

default test test
1 1
2 3
