外部类型issue的JSON序列化-将map[string]接口{}项转换为整数

package main

import (
    "encoding/json"
    "fmt"
)

func main() {
    data := map[string]interface{}{
        "key1": 123,
        "key2": "456",
        "key3": 789,
    }

    result := make(map[string]int)

    for key, value := range data {
        switch v := value.(type) {
        case int:
            result[key] = v
        case string:
            // 尝试将字符串转换为整数
            if intValue, err := strconv.Atoi(v); err == nil {
                result[key] = intValue
            } else {
                // 处理转换失败的情况
                fmt.Printf("Failed to convert value for key %s to int\n", key)
            }
        default:
            // 处理其他类型的值
            fmt.Printf("Unsupported value type for key %s\n", key)
        }
    }

    jsonData, err := json.Marshal(result)
    if err != nil {
        fmt.Println("Failed to marshal JSON")
        return
    }

    fmt.Println(string(jsonData))
}
