在做一個(gè)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(wù)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(wù)器上的話,那么上傳到一個(gè)文件夾里面。如:img
2、存儲(chǔ)時(shí)候存儲(chǔ)的是鏈接
問題:當(dāng)我刪除的時(shí)候如何刪除呢?數(shù)據(jù)庫(kù)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(chǔ)存的目錄存到數(shù)據(jù)庫(kù)中,順便問下你做圖片展示網(wǎng)站前臺(tái)模板是用的什么哇?
我最近也準(zhǔn)備做一個(gè)圖片展示網(wǎng)站呢
------解決方案--------------------
如果數(shù)據(jù)庫(kù)存的路勁的話就只有通過代碼來維護(hù)了,在Linux下還要設(shè)計(jì)文件操作權(quán)限問題
------解決方案--------------------
數(shù)據(jù)庫(kù)存的是路徑
直接unlink(path)

如果你打算使用?阿里云?(或其他云服務(wù))那么樓上朋友的介紹對(duì)你都無效了
你需要先認(rèn)真閱讀開發(fā)指南,尤其是其中有關(guān)文件上傳的章節(jié)
------解決方案--------------------
可以,阿里云的獨(dú)立服務(wù)器。用了幾年了。不過因?yàn)槭窃扑砸彩怯胁簧俣贪宓牡胤降模热鐢?shù)據(jù)庫(kù)的并發(fā),查詢速度等

[Common Directory Description] Directory/bin stores binary executable files (ls, cat, mkdir, etc.), and common commands are generally here. /etc stores system management and configuration files/home stores all user files. The root directory of the user's home directory is the basis of the user's home directory. For example, the home directory of the user user is /home/user. You can use ~user to represent /usr to store system applications. The more important directory /usr/local Local system administrator software installation directory (install system-level applications). This is the largest directory, and almost all the applications and files to be used are in this directory. /usr/x11r6?Directory for storing x?window/usr/bin?Many

Setting the location of the interpreter in PyCharm can be achieved through the following steps: 1. Open PyCharm, click the "File" menu, and select "Settings" or "Preferences". 2. Find and click "Project:[Your Project Name]" and select "PythonInterpreter". 3. Click "AddInterpreter", select "SystemInterpreter", browse to the Python installation directory, select the Python executable file, and click "OK". When setting up the interpreter, you need to pay attention to path correctness, version compatibility and the use of the virtual environment to ensure the smooth operation of the project.

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.

The installation and configuration of MySQL can be completed through the following steps: 1. Download the installation package suitable for the operating system from the official website. 2.

After installation, configure environment variables to ensure that the bin directory of MySQL is in PATH. 4. When creating a user, follow the principle of minimum permissions and set a strong password. 5. Adjust the innodb_buffer_pool_size and max_connections parameters when optimizing performance. 6. Back up the database regularly and optimize query statements to improve performance.

Informix and MySQL are both popular relational database management systems. They perform well in Linux environments and are widely used.

MySQL: The installation process of MySQL is relatively simple, and can be easily installed through system package management tools (such as apt or yum), and there are a large number of tutorials and community support on the network for reference. Performance Informix: Informix has excellent performance and

I have a lot of experience in participating in VSCode offline technology exchange activities, and my main gains include sharing of plug-in development, practical demonstrations and communication with other developers. 1. Sharing of plug-in development: I learned how to use VSCode's plug-in API to improve development efficiency, such as automatic formatting and static analysis plug-ins. 2. Practical demonstration: I learned how to use VSCode for remote development and realized its flexibility and scalability. 3. Communicate with developers: I have obtained skills to optimize VSCode startup speed, such as reducing the number of plug-ins loaded at startup and managing the plug-in loading order. In short, this event has benefited me a lot and I highly recommend those who are interested in VSCode to participate.
