导语：使用将gitlab中某个项目的分支提取出来后返回的是interface类型。希望转换成string后存入数据库。
interface 转 string 代码是抄来的～
// Strval 获取变量的字符串值
// 浮点型 3.0将会转换成字符串3, "3"
// 非数值或字符类型的变量将会被转换成JSON格式字符串
func Strval(value interface{}) string {
// interface 转 string
var key string
if value == nil {
return key
}
switch value.(type) {
case float64:
ft := value.(float64)
key = strconv.FormatFloat(ft, 'f', -1, 64)
case float32:
ft := value.(float32)
key = strconv.FormatFloat(float64(ft), 'f', -1, 64)
case int:
it := value.(int)
key = strconv.Itoa(it)
case uint:
it := value.(uint)
key = strconv.Itoa(int(it))
case int8:
it := value.(int8)
key = strconv.Itoa(int(it))
case uint8:
it := value.(uint8)
key = strconv.Itoa(int(it))
case int16:
it := value.(int16)
key = strconv.Itoa(int(it))
case uint16:
it := value.(uint16)
key = strconv.Itoa(int(it))
case int32:
it := value.(int32)
key = strconv.Itoa(int(it))
case uint32:
it := value.(uint32)
key = strconv.Itoa(int(it))
case int64:
it := value.(int64)
key = strconv.FormatInt(it, 10)
case uint64:
it := value.(uint64)
key = strconv.FormatUint(it, 10)
case string:
key = value.(string)
case []byte:
key = string(value.([]byte))
default:
newValue, _ := json.Marshal(value)
key = string(newValue)
}
return key
}
调用测试
str4 := Strval(out)
fmt.Printf("out type:%T\n", str4)
beego.Info(str4)
输出结果
类型已经转换为string 每个value加上了 “”
