如何在 php 中创建 Google Alert

问题描述

我花了很多时间在上面，但没有找到任何可行的解决方案...... 我试过下面的代码..但总是其他情况正在运行“没有找到登录表单1” 我已经尝试了另一个 coders11 实现的 api，但它也被弃用了... 我找到了许多其他解决方案，但在 PHP 中没有...我正在 PHP 中寻找解决方案...

解决方法

您不能再使用密码和电子邮件登录谷歌警报，您必须通过登录谷歌警报并将它们从开发控制台复制出来，然后在执行 curl 请求时将它们作为参数传递来预先创建 cookie。查看我用 php 编写的 google alerts api。也许这对你有帮助https://github.com/Trivo25/google-alerts-api-php
