问题：
Golang使用未知密钥解析JSON〔重复〕
晋功
我正在尝试用动态字段键将json解组到json从storcli utility for linux返回的结构。一部分代码运行良好，但是如果json数据包含许多结构，我就不能解组它。我认为这是因为DriveDetailedInformation结构没有所有的json标签。有人能帮我吗？

因为你的键值不正确。下面是我修改的代码。
type DriveDetailedInformation struct {
DriveState DriveStateStruct `json:"Drive /c0/e31/s0 State"`
DriveDeviceAttributes DriveDeviceAttributesStruct `json:"Drive /c0/e31/s0 Device attributes"`
DrivePoliciesSettings DrivePoliciesSettingsStruct `json:"Drive /c0/e31/s0 Policies/Settings"`
InquiryData string `json:"Inquiry Data"`
}
type DriveDetailedInformation1 struct {
DriveState DriveStateStruct `json:"Drive /c0/e31/s1 State"`
DriveDeviceAttributes DriveDeviceAttributesStruct `json:"Drive /c0/e31/s1 Device attributes"`
DrivePoliciesSettings DrivePoliciesSettingsStruct `json:"Drive /c0/e31/s1 Policies/Settings"`
InquiryData string `json:"Inquiry Data"`
}
func main() {
var f jsonStruct
err := json.Unmarshal([]byte(jsonData), &f)
if err != nil {
fmt.Println("Error parsing JSON: ", err)
}
for _, controller := range f.Controllers {
for k, v := range controller.ResponseData {
switch k {
case "Drive /c0/e31/s0","Drive /c0/e31/s1":
var ds []DriveStruct
if err := json.Unmarshal(*v, &ds); err == nil {
fmt.Println(k, ds)
}
case "Drive /c0/e31/s1 - Detailed Information":
var dds1 DriveDetailedInformation1
if err := json.Unmarshal(*v, &dds1); err == nil {
fmt.Println(k, dds1)
}
case "Drive /c0/e31/s0 - Detailed Information":
var dds DriveDetailedInformation
if err := json.Unmarshal(*v, &dds); err == nil {
fmt.Println(k, dds)
}
}
}
}
}
我认为响应数据可以在一个结构中解析。

我有一个json字符串，如下所示： 我想从上面的json字符串中提取< code>name和< code>age的值。我看了这个在http://play.golang.org/p/YQgzP7KPp9 golang网站给出的例子 但是我的问题是json顶层的键是动态的。这意味着< code>bvu62fu6dq是动态的。我创建了这样的结构: 但不确定如何提取<代码>姓名 和<代码>年龄 。我的代码

问题内容： 我在将以下格式的json数据解组到结构时遇到麻烦。json的结构对我来说有点令人困惑，因此我为解组它所做的所有愚蠢的事情表示歉意。 我正在尝试使用以下结构将其解组。 这些字段在生成时将是未知的，并且会发生变化，并且存在此字段 在没有外部密钥的服务器名称之后，这再次让我感到困惑。我尝试了很多组合以了解如何将其解组，但是我失败了。 什么是使json字段解组为结构的有效方法？ 问题答案： 您

在我的笔记本电脑（MSI GE63VR 7RE）上，按下空格键（和其他一些键）时，GLFW将GLFW_KEY_传递给键回调函数未知的键。 几乎所有的钥匙都有扫描码，但这些钥匙应该是特定于机器的，没有方便的方法将它们映射到正确的钥匙名称。 为什么GLFW不能识别我的空间密钥GLFW_KEY_SPACE，解决这个问题的最佳方法是什么？ 我在arch linux与wayland和我使用glfw-wayl

问题内容： 有没有办法用python向json添加重复键？ 据我了解，python词典中不能有重复的键。通常，创建json的方法是先创建字典，然后再创建。但是，我需要在JSON中使用重复的键进行测试。但是我不能这样做，因为我不能在python字典中添加重复的键。我正在尝试在python 3中做到这一点 问题答案： 您总是可以手动构造这样的字符串值。 另一方面，可以使 C* Python 模块对重复
