上传文件绕过自己的服务器直接到云存储上,现在能实现么?
回复讨论(解决方案)
不可能,上传文件的数据是打包在 http 数据包中的,而 php 程序要在 http 数据包解包之后才开始执行
如果你是在客户端直接调用云存储客户端伤处啊文件的话,那么就和 php 没有半毛钱的关系了
你大慨是想说 API 吧?看看提供云存储的商家有没有提供API给你 直接调直接到那边
只能传到自己服务器同步到云然后删除
理论上,只有一种可能方法,就是利用客户端浏览器的html和js将文件直接传入到另一个域的服务器,即云端,但这就跨域了吧,浏览器会禁止的。不过你可以试试看是否跨域。
你看云端支持不支持上传完后跳转回来,并且给你信息咯

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.
