我想爲Lua數組中的每個字符串元素存儲一些值。Lua:將值存儲在字符串數組中

-- Number of connections per host and total connections for each browser/user_agent
user_agent[1].max_conn_perhost , user_agent[1].max_conn_total = 6, 17
user_agent[2].max_conn_perhost , user_agent[2].max_conn_total = 6, 10
user_agent[3].max_conn_perhost , user_agent[3].max_conn_total = 6, 10
user_agent[4].max_conn_perhost , user_agent[4].max_conn_total = 6, 16
user_agent[5].max_conn_perhost , user_agent[5].max_conn_total = 6, 16
user_agent[6].max_conn_perhost , user_agent[6].max_conn_total = 6, 35
user_agent[7].max_conn_perhost , user_agent[7].max_conn_total = 6, 35
user_agent[8].max_conn_perhost , user_agent[8].max_conn_total = 6, 16
這是拋出錯誤:
attempt to index field '?' (a string value)
我已經在一些例子中發現,如果我沒有初始化字符串數組,然後它會工作。 任何人都可以請建議任何更簡單的解決方案來實現這一目標或糾正問題。
非常感謝您解釋問題和解決方案! –
