How to keep order of keys when convert map[string]interface{} to json ? #2536
Description
1. What version of Go and system type/arch are you using?
go version go1.20.2 windows/amd64
2. What version of GoFrame are you using?
v2.3.3
3. Can this issue be re-produced with the latest release?
yes
4. What did you do?
package main
import (
"context"
"github.com/gogf/gf/v2/encoding/gjson"
"github.com/gogf/gf/v2/frame/g"
)
func main() {
amap := map[string]string{}
gjson.DecodeTo("{\"b\":\"b\",\"a\":\"a\"}", &amap)
g.Log().Info(context.Background(), amap)
result, _ := gjson.EncodeString(amap)
g.Log().Info(context.Background(), result)
}
INPUT is：
{"b":"b","a":"a"}
OUTPUT is:
{"a":"a","b":"b"}
5. What did you expect to see?
Keep the order of keys as that in map.
package main
import (
"context"
"github.com/gogf/gf/v2/encoding/gjson"
"github.com/gogf/gf/v2/frame/g"
)
func main() {
amap := map[string]string{
"c": "c",
"b": "b",
}
amap["a"] = "a"
g.Log().Info(context.Background(), amap)
result, _ := gjson.EncodeString(amap)
g.Log().Info(context.Background(), result)
}
I want get {"c":"c","b":"b","a":"a"} instead of {"a":"a","b":"b","c":"c"}.
6. What did you see instead?
Keys are order by alphabet.
