go接口返回空数组
go语言nil返回接口时是null,前端同事要求返回[]空数组,代码片段如下:
res := g.Map{ "list": menus, "statusOptions": statusOptions, "typeOptions": typeOptions, "fields": fields, //nil } response.SusJson(true, r, "ok", res)
解决办法:通过go语言自建数组形式替换fields变量
if fields==nil { fields = make([]int, 0) } res := g.Map{ "list": menus, "statusOptions": statusOptions, "typeOptions": typeOptions, "fields": fields, } response.SusJson(true, r, "ok", res)
至此解决前端需求,但是感觉代码没有优雅。
