When I use like &simplejson.Json{v}
(v is a interface read from file and it's actual data structure is map[string]interface{}), then show this error. Details:
A json file named abcd
{
"pids": [
{
"pid": 168043,
"target_regions": [
40,
25,
43,
299,
240
]
},
{
"pid": 168044,
"target_regions": [
63,
65,
68
]
}
]
}
And the go file is
package main
import (
"fmt"
"io/ioutil"
sjson "github.com/bitly/go-simplejson"
)
type pidInfo struct {
Pid uint64 `json:"pid"`
TargetRegions []uint32 `json:"target_regions"`
}
type pidUnitInfo struct {
Pid2Info map[uint64]*pidInfo
}
func build() error {
content, _ := ioutil.ReadFile("./abcd")
json, err := sjson.NewJson(content)
if err != nil {
return err
}
newPidUnitInfo(json)
return nil
}
func newPidUnitInfo(json *sjson.Json) (*pidUnitInfo, error) {
newInfo := new(pidUnitInfo)
newInfo.buildPid2Info(json)
return nil, nil
}
func (pui *pidUnitInfo) buildPid2Info(json *sjson.Json) error {
raw, ok := json.CheckGet("pids")
if !ok {
return fmt.Errorf("not found json key %v", "pids")
}
pids, err := raw.Array()
if err != nil {
return err
}
pui.Pid2Info = make(map[uint64]*pidInfo, len(pids))
for _, v := range pids {
fmt.Println(v)
m := &sjson.Json{v}
fmt.Println(m)
}
return nil
}
func main() {
build()
}
When I execute it, show implicit assignment of unexported field 'data' in simplejson.Json literal
at this line m := &sjson.Json{v}
.
