我正在嘗試創(chuàng)建地圖片段。盡管代碼可以很好地編譯，但在下面出現(xiàn)運(yùn)行時(shí)錯(cuò)誤：mapassign1: runtime·panicstring("assignment to entry in nil map");我嘗試制作一個(gè)Map數(shù)組，每個(gè)Map包含兩個(gè)指標(biāo)，即“ Id”和“ Investor”。我的代碼如下所示：for _, row := range rows {        var inv_ids []string        var inv_names []string        //create arrays of data from MySQLs GROUP_CONCAT function        inv_ids = strings.Split(row.Str(10), ",")        inv_names = strings.Split(row.Str(11), ",")        length := len(inv_ids);        invs := make([]map[string]string, length)        //build map of ids => names        for i := 0; i < length; i++ {            invs[i] = make(map[string]string)            invs[i]["Id"] = inv_ids[i]            invs[i]["Investor"] = inv_names[i]        }//for        //build Message and return        msg := InfoMessage{row.Int(0), row.Int(1), row.Str(2), row.Int(3), row.Str(4), row.Float(5), row.Float(6), row.Str(7), row.Str(8), row.Int(9), invs}        return(msg)    } //for我最初認(rèn)為類似下面的內(nèi)容會(huì)起作用，但是也不能解決該問(wèn)題。有任何想法嗎？invs := make([]make(map[string]string), length)
