在做一個圖片展示網(wǎng)站。想知道圖片是怎么存的?url?還是直接上傳到服務器然后拿到他的路徑?
上述兩種方法好像都可以。以第二種為例,
1、如果我要將圖片上傳到服務器上的話,那么上傳到一個文件夾里面。如:img
2、存儲時候存儲的是鏈接
問題:當我刪除的時候如何刪除呢?數(shù)據(jù)庫還好說,圖片在文件夾里面如何刪除?
求教大神!
------解決方案--------------------
在文件夾里面用unlink啊?就可以刪了?,把文件夾的儲存的目錄存到數(shù)據(jù)庫中,順便問下你做圖片展示網(wǎng)站前臺模板是用的什么哇?
我最近也準備做一個圖片展示網(wǎng)站呢
------解決方案--------------------
如果數(shù)據(jù)庫存的路勁的話就只有通過代碼來維護了,在Linux下還要設計文件操作權限問題
------解決方案--------------------
數(shù)據(jù)庫存的是路徑
直接unlink(path)
------解決方案--------------------
如果你打算使用?阿里云?(或其他云服務)那么樓上朋友的介紹對你都無效了
你需要先認真閱讀開發(fā)指南,尤其是其中有關文件上傳的章節(jié)
------解決方案--------------------
可以,阿里云的獨立服務器。用了幾年了。不過因為是云所以也是有不少短板的地方的,比如數(shù)據(jù)庫的并發(fā),查詢速度等

The main difference between Java and other programming languages ??is its cross-platform feature of "writing at once, running everywhere". 1. The syntax of Java is close to C, but it removes pointer operations that are prone to errors, making it suitable for large enterprise applications. 2. Compared with Python, Java has more advantages in performance and large-scale data processing. The cross-platform advantage of Java stems from the Java virtual machine (JVM), which can run the same bytecode on different platforms, simplifying development and deployment, but be careful to avoid using platform-specific APIs to maintain cross-platformity.

Understanding Nginx's configuration file path and initial settings is very important because it is the first step in optimizing and managing a web server. 1) The configuration file path is usually /etc/nginx/nginx.conf. The syntax can be found and tested using the nginx-t command. 2) The initial settings include global settings (such as user, worker_processes) and HTTP settings (such as include, log_format). These settings allow customization and extension according to requirements. Incorrect configuration may lead to performance issues and security vulnerabilities.
