php 邮件发送问题解决
验证错误不能登陆,需重新输验证码,或在发送新的验证码到邮箱。为了实现此功能,我用到了如何向邮箱发送邮件,以及获取登陆ip的知识
这段时间修改了一下我们系统的登陆功能,为了更加安全,增加了发送邮件验证功能。当用户登陆的时候判断登陆ip是否是之前登陆过的,如果不是的话,需要向邮箱里发送验证码,然后把收到的验证码输入再登陆,如果验证码正确并且时间没有超过规定时间,可以登陆,并且记下此次登陆的ip和时间,以后再以此ip登的话,就不用验证了。如果时间超过了,,验证码失效,需重新发送。验证错误不能登陆,需重新输验证码,或在发送新的验证码到邮箱。为了实现此功能,我用到了如何向邮箱发送邮件,以及获取登陆ip的知识。下面整理一下,以便以后自己查看。
发送邮件:
首先需要下载phpmail的压缩包,然后解压,把解压后的文件复制到项目中。在项目中引入文件。
复制代码 代码如下:
require("phpmailer/class.phpmailer.php"); //文件的路径具体看自己的项目中的路径是怎么样的
