axios post 回传数组至后台

Posted 2022-02-08 Luckyfish小文

就是简单的把值回传给后台，只不过值换成了数组而已，用原来FormData , URLSearchParams均不管用，折腾了半天

偶然看到这个帖子：https://blog.csdn.net/lee576/article/details/120347400，唉，原来就是这么简单！

前端代码：

//Vue  data中定义接收要删除id的数组 
data() 
            return 
                idList:[]
            
        

///批量删除用户
            delUser() 
                const length = this.multipleSelection.length;
                for (let i = 0; i < length; i++) 
                    this.delList.push(this.multipleSelection[i].OrderUserLogID);
                
                this.$confirm(\'确定要删除用户吗？\').then(_ => 
                    let _ids = this.idList;
                    //回传数组方法（数组格式：[\'1\',\'2\']）：直接回传，无需赋参
                    axios.post(\'/CustomerInfo/Delete\', _ids)
                        .then(res => 
                        if (res.data.success == true) 
                            this.$message(
                                message: res.data.message,
                                type: "success"
                            );
                            this.getUserList();
                         else 
                            this.$message(
                                message: res.data.message,
                                type: "error"
                            );
                        
                    )
                )
            

后台代码：

       [HttpPost]
        public ActionResult Delete([FromBody] string[] ids)
        
            if(ids.Length>0)
            
                int[] idArray = Array.ConvertAll(ids,u=>int.Parse(u));
                foreach(int id in idArray)
                
                    var model = userInfoIBll.GetEntityOne(u => u.OrderUserLogID==id);
                    userInfoIBll.Delete(model);
                
                return Json(new ReturnJsonInfo(true, "用户信息删除成功!", null));
            
            else
            
                return Json(new ReturnJsonInfo(false, "用户信息删除失败!", null));
