我想上传一个包含联系人号码的excel文件 [英] I want to upload an excel file which has contacts numbers

问题描述

我想上传一个excel文件，其中包含客户端的联系人号码字段，然后向这些收件人发送邮件。

我不知道是否我必须首先在数据库中保存联系人然后发送或者我可以从excel中提取每个联系人并逐个发送（给收件人）。

请有人可以帮助处理可以执行的代码it。

Hi,
I want to upload an excel file which has a field of contacts numbers from clients side, then send message to those Recipients.
I dont know if I have to save in the database the contacts first and then send or I can extract each contact from excel and send one by one(to the Recipients).
Please can someone help with the code that can do it.

推荐答案

我认为

如果你没有要求将这些联系人存储到数据库那么我的ans就是保持联系在临时表中或者您可以直接向所有联系人发送消息，或者您的API可能有能力一次性发送消息，如逗号saprated ..... 545454545,545778787,5545454，

i think
if you don't have requirement to store those contact to database then my ans is just keep all contact in temp table or you can directly send message to all contact one by one or your API may have ability to send message at one shot like comma saprated .....545454545,545778787,5545454,
