将json解组为结构体：不能将数组解析为Go值 [英] Unmarshal json into struct: cannot unmarshal array into Go value

问题描述

我有一项通过REST为我提供属性的服务。现在我想将身体解组到一个属性结构中。请参阅此操场示例：点击。当我只有一个属性时，我可以轻松将它解组为 Property 。然而，来自服务器的ACTUAL响应在某种程度上是不同的。我想解组的实际响应是这样的：

I have a service which provides me properties through REST. Now I want to unmarshal the body into a properties struct. Please see this playground example: click. When I have only one property, I can easily unmarshal it into a Property. However the ACTUAL response from the server is somehow difference. The actual response I want to unmarshal is this:

[
    {
        "key": "blabla",
        "secret": false,
        "type": "string",
        "value": "hereisthevalue"
    },
    {
        "key": "yepyepakey",
        "secret": true,
        "type": "string",
        "value": "dummy"
    }
]

不幸的是我不知道如何解组。有人可以请我指出正确的方向吗？

Unfortunately I don't know how to unmarshal this. Can someone please point me in the right direction?

推荐答案

您需要解组成一片属性：
< a href =http://play.golang.org/p/eRgjfBHypH> http://play.golang.org/p/eRgjfBHypH

You need to unmarshal into a slice of Property: http://play.golang.org/p/eRgjfBHypH

var props []Property
er := json.Unmarshal(resp, &props)
if er != nil {
    panic(er)
} else {
    fmt.Println(props)
}
