Json 将接口{}转换为映射

我试图读取一个json文件，代码如下所示

var configurations map[string]interface{}

func GetConfigMap(name string) interface{} {
    valueMap := configurations[name]
    return valueMap.(map[string]interface{})
}

我试着看下面的地图

glossary := jsonreader.GetConfigMap("glossary")
fmt.Println(glossary["GlossDiv"])

{    "glossary": {
        "title": "example glossary",
        "GlossDiv": {
            "title": "S",
            "GlossList": {
                "GlossEntry": {
                    "ID": "SGML",
                    "SortAs": "SGML",
                    "GlossTerm": "Standard Generalized Markup Language",
                    "Acronym": "SGML",
                    "Abbrev": "ISO 8879:1986",
                    "GlossDef": {
                        "para": "A meta-markup language, used to create markup languages such as DocBook.",
                        "GlossSeeAlso": ["GML", "XML"]
                    },
                    "GlossSee": "markup"
                }
            }
        }
    }
}

json结构如下所示

glossary := jsonreader.GetConfigMap("glossary")
fmt.Println(glossary["GlossDiv"])

{    "glossary": {
        "title": "example glossary",
        "GlossDiv": {
            "title": "S",
            "GlossList": {
                "GlossEntry": {
                    "ID": "SGML",
                    "SortAs": "SGML",
                    "GlossTerm": "Standard Generalized Markup Language",
                    "Acronym": "SGML",
                    "Abbrev": "ISO 8879:1986",
                    "GlossDef": {
                        "para": "A meta-markup language, used to create markup languages such as DocBook.",
                        "GlossSeeAlso": ["GML", "XML"]
                    },
                    "GlossSee": "markup"
                }
            }
        }
    }
}

我得到一个例外，说-

invalid operation: glossary["GlossDiv"] (type interface {} does not support indexing)

---

如何实现这一点？

基于您的问题，我不确定您想做什么，但您不能更改函数的返回类型吗

func GetConfigMap(name string) map[string]interface{} {
    valueMap := configurations[name]
    return valueMap.(map[string]interface{})
}

您可以在我发布的示例中看到，将GetConfigMap的返回类型从接口{}更改为map[string]接口{}，这样您就可以随心所欲了。
