请问怎么把sql.Rows转成map

如题..我想把sql.Rows转成map..请问怎么实现写了下..失败了代码如下 func (this *Admin) Query(query string, args ...interface{}) ([]map[string]interface{}, error) { db, err := this.getDB() defer db.Close() if err != nil { return nil, err } stmt, err := db.Prepare(query) defer stmt.Close() if err != nil { return nil, err } res, err := stmt.Query(args...) defer res.Close() if err != nil { return nil, err } fields, _ := res.Columns() fieldslen := len(fields) ms := []map[string]interface{}{} for res.Next() { m := map[string]interface{}{} scaninterfaces := make([]interface{}, 0, fieldslen) for _, field := range fields { //m[field] = 0 scaninterfaces = append(scaninterfaces, m[field]) } res.Scan(scaninterfaces...) ms = append(ms, m) } return ms, nil }
