导读:我想声明一个函数接受接口数组,例如: func (this *CvStoreServiceImpl) setItemList(coll *mgo.Collection,itemList ...interface{}) (err error) Howerver,当我将此函数称为跟随失败时: jobList := cvRaw.GetJobList()this.setItemList(jobColl,jobList..
我想声明一个函数接受接口数组,例如:
func (this *CvStoreServiceImpl) setItemList(coll *mgo.Collection,itemList ...interface{}) (err error) Howerver,当我将此函数称为跟随失败时: jobList := cvRaw.GetJobList() this.setItemList(jobColl,jobList...) 这里有错误: cannot use cvRaw.GetJobList() (type []*cv_type.CvJobItemRaw) as type []interface {} in argument to this.setItemList 解决方法
我想你要找的是
is this
package main import "fmt" func main() { interfacetious := []interface{}{"s",123,float64(999)} stuff(interfacetious) stuff2(interfacetious...) stuff2("or","separate",float64(99),"values") } // Stuff can only work with slice of things func stuff(s []interface{}) { fmt.Println(s) } // Stuff2 is polyvaridc and can handle individual vars,or a slice with ... func stuff2(s ...interface{}) { fmt.Println(s) } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
