我已经为杂志公司建立了一个注册流程的应用程序。该应用程序特别适用于通过条带支付每月订阅的订阅者。
注册过程如下：
使用POST执行Ajax，并将用户详细信息发送到远程服务器上名为registration_processing.php的php页面。
我首先检查应用数据库中是否已存在电子邮件地址
如果电子邮件不存在，那么我会对杂志公司的条带帐户进行API调用，以获取其订阅者电子邮件地址的列表。 （三是大约700，所以我使用分页。）
我根据从条带收到的订阅者电子邮件列表检查使用ajax发布请求发送的电子邮件。
如果匹配，则将用户详细信息存储到应用数据库中，并将用户带到应用的主页。
当我在启动应用程序之前测试它时，这非常有效。
但是，当应用程序启动时，多个用户开始完成此注册过程，现在发生以下情况：
他们的订阅者电子邮件地址成功匹配，他们的详细信息存储在app数据库中，但是ajax调用正在执行错误功能，错误消息＆＃34; Gateway超时＆＃34;。在测试时，它需要大约32秒才能发生超时。 对此远程服务器的所有其他ajax请求都正常工作。 我查看了phpinfo.php，我注意到＆＃34; max_execution_time＆＃34;是120.我不确定这是否与任何事情有关。我需要增加这个吗？ 谢谢你的帮助。
