I would like to ask the iris framework of golang to parse the form into the structure. can you continue to parse when there are values in the form that do not exist in the structure? - Codes Helper

problem description

golang"s iris framework parses the form into the structure and stops parsing when there are values in the form that do not exist in the structure

the environmental background of the problems and what methods you have tried

the recently written project uses the readform method of the iris framework to read the form. The current side passes the admin_id field (the field is not in the predefined structure). After parsing to this field, iris stops parsing and returns an error

    FunctionType    int64   `form:"function_type" validate:"omitempty,numeric"`
    Uri             string  `form:"uri" validate:"omitempty,url"`
}

var formParam addForm // 
var errP errs.Error   // 

// 
if err := ctx.ReadForm(&formParam); err != nil {

}
// 
var admin backend.Admin
if functions.ReadForm(&admin, ctx.Request().PostForm) != nil || admin.Valid() != nil {
    ctx.JSON(backend.Response(iris.Map{consts.CODE: errs.ERR_PARAM_WRONG}))
    return
}

what result do you expect? What is the error message actually seen?

iris automatically skips when parsing to a field that does not exist. The actual iris ends parsing directly and returns an error when parsing to the point that the field does not exist in the structure
