Json unmarshalling in GO
问题
我正在尝试将服务器返回的JSON响应解组成不同的类型，但是我找不到如何做到这一点。
可以正常工作的类型是：
type ServerResponse struct {Total intData []User}type User struct {Name stringAge int}
我可以成功地解组JSON并获得预期的User类型。
我想做的是处理各种服务器响应并在之后进行转换。例如：
type ServerResponse struct {Total intData []ServerItem}type User struct {ServerItemName stringAge int}type Book struct {ServerItemName stringAuthor string}
然后，可以使用User(response.Data)或response.Data.(User)将其转换为具体类型，以便稍后的函数正确进行类型检查。
请问有人可以告诉我从哪里开始解决这个问题吗？
英文:
I am trying to unmarshal a json response from the server into various types, but I
am not finding how to do it.
The types which work are :-
type ServerResponse struct {Total intData []User}type User struct {Name stringAge int}
and I can successfully unmarshal the json and receive the expected User type.
What I want to do is handle various server responses and convert after the
fact. eg.
type ServerResponse struct {Total intData []ServerItem}type User struct {ServerItemName stringAge int}type Book struct {ServerItemName stringAuthor string}
Then use either User(response.Data) or response.Data.(User) to make it a
concrete type so that later functions type check correctly.
Please could anyone let me know where to start looking to solve this issue.

我不认为这可以轻松地完成。只需解码为map[string]interface{}，然后根据此创建你需要的内容。

I don't think that this can be done easily. Just decode to map[string]interface{} and create your stuff from this.

这里我写了一个简单的程序，用于解析 JSON。你可以在这个链接中查看：http://play.golang.org/p/51eiswgznR。
你可能还想阅读一下 encoding/json 的文档，可以在这个链接中找到：http://golang.org/pkg/encoding/json/。
