This code throws an error: ./prog.go:10:10: struct field Field2 repeats json tag "field_1" also at prog.go:10
see https://play.golang.org/p/sFZ-6GWUO0J Why not use this: type a_1_struct_name struct { Field1 string `json:"field_1"` Field2 string `json:"field_2"` } ________________________________________ Von: golang-nuts@googlegroups.com <golang-nuts@googlegroups.com> im Auftrag von amarjeetanandsi...@gmail.com <amarjeetanandsi...@gmail.com> Gesendet: Freitag, 3. Juli 2020 16:11 An: golang-nuts Betreff: [go-nuts] ignore json tag for field list in a struct field If there is a json tag with multiple fields in a single line, is there any json parser which will consider the json field name? Like in below, "encoding/json" ignores the fields to unmarshal if there are multiple fields in a single line with a json tag. EX: below code will print nothing. type a_1_struct_name struct { Field1, Field2 string `json:"field_1"` } func main() { a := a_1_struct_name{} j := `{"field_1": "field_1_val"}` if err := json.Unmarshal([]byte(j), &a); err != nil { log.Fatal(err) } fmt.Println(a) } But if we remove the json tag `json:"field_1"` and the change the value of json(j) accordingly, it prints {field_1_val } I am writing a program to get the json equivalent tag of struct fields using reflect. My question is, is it safe to ignore the fieldList(comma separated struct fields in a single line) if there is a json tag with it? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
