m := j.(map[string]interface{}) 对我不起作用
panic: interface conversion: interface {} is []interface {}, not map[string]interface {}
所以我最终会用这样的代码来使它工作?不要认为这是正确的做法:)
var j interface{}
err = json.Unmarshal(b, &j)
if err != nil {
log.Print(err.Error())
}
m := j.([]interface{}) //map[string]interface{}
for k, v := range m {
switch vv := v.(type) {
case string:
fmt.Println(k, "is string", vv)
case int:
fmt.Println(k, "is int", vv)
case []interface{}:
fmt.Println(k, "is an array:")
for i, u := range vv {
fmt.Println(i, u)
}
case map[string]interface{}:
for k2, v2 := range v.(map[string]interface{}) {
switch vv2 := v2.(type) {
case string:
fmt.Println(k2, "is string", vv2)
case int:
fmt.Println(k2, "is int", vv2)
case []interface{}:
fmt.Println(k2, "is an array:")
for i2, u2 := range vv2 {
fmt.Println(i2, u2)
}
default:
fmt.Println(k2, "is of a type I don't know how to handle")
}
}
default:
fmt.Println(k, "is of a type I don't know how to handle")
}
}
