gdb查询结果json转换丢失精度

[qinyuguang]

go 1.17
gf v2.0.6

生成gjson.Json类型的entity，查询结果会丢失精度。实际是在gconv.Struct时丢失的
下面用gconv.Struct复现

package main

import (
	"github.com/gogf/gf/v2/container/gvar"
	"github.com/gogf/gf/v2/encoding/gjson"
	"github.com/gogf/gf/v2/util/gconv"
	"github.com/gogf/gf/v2/util/gutil"
)

func main() {
	var json *gjson.Json
	_ = gconv.Struct(gvar.New("[1, 2, 336371793314971759]"), &json)
	gutil.DumpWithType(json)
}

输出丢失精度
*gjson.Json(24) "[1,2,336371793314971800]"

补充gdb操作

数据库

CREATE TABLE test_json (
	"data" json NOT NULL
);
INSERT INTO test_json ("data") VALUES('[1, 2, 336371793314971759]');

代码

package main

import (
	_ "github.com/gogf/gf/contrib/drivers/pgsql/v2"
	_ "github.com/lib/pq"

	"context"

	"github.com/gogf/gf/v2/encoding/gjson"
	"github.com/gogf/gf/v2/frame/g"
)

type TestJson struct {
	Data *gjson.Json `json:"data"`
}

func main() {
	var res *TestJson
	if err := g.DB().Model("test_json").Scan(&res); err != nil {
		g.Log().Debug(context.Background(), "err:", err)
	}
	g.DumpWithType(res)
}

输出

*TestJson(1) {
    Data: *gjson.Json(24) "[1,2,336371793314971800]",
}
