比较Golang中的两张地图

Question

I have two Maps:

First one:

map[11:manufacturer 2:upc 5:short_description 10: 4:category 6: 7:url 
8:image 9: 0:name 1:mpn 3:sku]

Second one:

map[3:manufacturer 5:mpn 8:category_path 10:is_in_stock 2:final_price 
1:name 4:short_description 6:thumbnail 7:url 9:furniture_type 0:sku]

How I can compare both and select those values from the second one which matches the first one.

Answer 1

If I understand your question correctly, the following should work:

Step I. Reverse keys and values in your 2nd map: reversed_map_2. This assumes that the values are unique.

Step II. Loop over values in your 1st map, now you can look up the values in reversed_map_2
