golang将interface{}转化成[]interface{}、interface{}转化成map、interface{}转化成string
//将map[string]interface{}转换成map[string][]map[string]string
result := make(map[string]interface{})
//1.将interface{}转[]interface{}
//取interface{}
tmp1 := result["data"]
tmpResult, ok := tmp1.([]interface{})
if !ok {
log.Print("失败")
}
//2.将interface{}转map
for _, v := range tmpResult {
tmp2 := v.(map[string]interface{})
}
//3.将interface{}转化成string
last := InterfaceToString(tmp2)
