Golang: extend map[string]interface{} that often use with JSON.
Need to merge 2 maps/json in golang. The result is a new extend map.
For example:-
- map/json#1
map[string]interface{}{
"key1": "value1",
"dup1": map[string]interface{}{
"key2": "value2",
},
}{
"key1": "value1",
"dup1": {
"key2": "value2"
}
}- map/json#2
map[string]interface{}{
"key3": "value3",
"dup1": map[string]interface{}{
"key4": "value4",
},
}{
"key3": "value3",
"dup1": {
"key4": "value4"
}
}- Merged result:-
map[string]interface{}{
"key1": "value1",
"key3": "value3",
"dup1": map[string]interface{}{
"key2": "value2",
"key4": "value4",
},
}{
"key1": "value1",
"key3": "value3",
"dup1": {
"key2": "value2",
"key4": "value4"
}
}m1 := map[string]interface{}{
"key1": "value1",
"dup1": map[string]interface{}{
"key2": "value2",
},
}
m2 := map[string]interface{}{
"key3": "value3",
"dup1": map[string]interface{}{
"key4": "value4",
},
}
result := ExtendMap(m1, m2)See the complex thing in extend_map_test.go
