首先,我们需要先定义一个map,并给其赋值。我们以一个简单的示例来说明: //定义一个map类型varinfoMapmap[string]interface{}//初始化map,并插入数据infoMap =map[string]interface{}{"name":"张三","age":25,"position":"Golang开发工程师","hobby": []string{"游泳","看电影","打篮球", }, } AI代...
但很多时候并不能直接将Map对象的toString() 而是应该转换为JsonObject后再调用toString()后存入就正常...

如果输入是 JSON 字符串,我们首先将其解析为map[string]interface{}格式,然后将其映射到结构中。 func jsonDecode() { var jsonStr = `{ "name": "Foo", "age": 21, "gender": "male" }` type Person struct { Name string Age int Gender string ...
