golang-using reflection to assign values to structures

This is a creation in Article, where the information may have evolved or changed.

Because you want to assign a value to some members of a struct, but have no specific name, the JSON name of the tag is indexed and assigned by JSON name one by one

//assigning members in a struct to JSON namesFunc Setstructfieldbyjsonname (PTRInterface{}, Fields map[string]Interface{}) {logger. Debug ("Fields :", Fields) V:= Reflect. ValueOf (PTR). Elem ()//The struct variable     forI: =0; I < V.numfield (); i++{fieldInfo:= V.type (). Field (i)//a reflect. StructfieldTag: = Fieldinfo.tag//a reflect. StructtagName: = tag.
