Objective RESTful development, object to Json,json to the object is very frequent operation, how to less repetitive code, for this purpose to open this article All your code on GitHub. Simplifying data structures Each time you need to return the data have code,msg,data these fields, each type of these fields is too complicated

We can use interface to receive JSON. Unmarshal, and then uses the type assertion attribute for subsequent operations.Package Mainimport ("Encoding/json" "FMT") func main () {b: = []byte (' {"Name": "Wednesday", "Age": 6, "parents": ["Gomez", " Morticia "]} ') var f interface{}json. Unmarshal (b, f) M: = f. (map[string]interface{}) fmt. Println (m["parents"]) //

The Json.unmarshal () function finds the fields in the target structure in the order of a contract and matches if one is found. JSON when the data structure in the JSON data does not match the target type in go. The Unmarshal () function discards the field during decoding. The Json.unmarshal () function also supports

by default -stubs only generate stubs for marshaler/unmarshaler funcs There are several options to be aware of: -lower_camel_case:将结构体字段field首字母改为小写。如Name=>name。 -build_tags string:将指定的string生成到生成的go文件头部。 -no_std_marshalers：不为结构体生成MarshalJSON/UnmarshalJSON函数。 -omit_empty:没有赋值的field可以不生成到json，否则field为该字段类型的默认值。-output_filename:定义生成的文件名称。-pkg:对包内指定有`//easyjson:json`结构体生成对应的easyjson配置。-snke_case:可以下划线的field如`Name_Student`改为`name_student`。 Use
