先将map转换成JSON,再通过 JSON 转换成struct 操作有点繁琐 func TestMapToStructByJson(t *testing.T) { beforeMap := map[string]interface {}{ "id":"123", "user_name":"酒窝猪", "address":[]map[string]interface{}{{"address": "address01"}, {"address": "address02"}}, } var afterSt...

fmt.Println(string(b)) } map转struct 需要安装一个第三方库 在命令行中运行: go get github.com/goinggo/mapstructure 例子: func MapToStructDemo(){ mapInstance := make(map[string]interface{}) mapInstance["Name"] ="jqw"mapInstance["Age"] =18varpeople People ...
2. 合并 map 到 struct 接下来我们看另一个场景:我们有一个 map,需要将其内容合并到一个已有的 struct 中。这种需求在动态配置加载时特别常见。 funcmapToStruct(){ varm =make(map[string]interface{})m["name"] ="Tom"m["age"] =23m["email"] ="12...

Sorry to be persistent with this. I wasn't aware that yaml was able to have different types has keys than string. However, with the following example I see that newstruct is being considered has a map[interface{}]interface{}, is it a bug...

因为我无法实现外部类型的方法,所以我创建了一个类型type DenseEx struct { Mtx *mat.Dense}并实现MarshalJSON方法如下func (d DenseEx) MarshalJSON() ([]byte, error) { js := map[string]interface{}{} rows, cols := d.Mtx.Dims() js["cols"] = cols js["rows"] = rows fltVals := make(...
