Cloud Storage: Comparison between Alibaba Cloud and Qiniu_PHP Tutorial
Conclusion:
阿里云存储 | 七牛云存储 | |
标准:REST、HTTP | 99%符合 | 50% |
基本功能:送二级域名、绑定域名、CDN | 支持 | 支持 |
自定义文件HTTP header | 支持 | 少量支持 |
高级服务:图片处理 | 不提供 | 很完善地提供 |
收费策略 | 收费 | 小流量免费。大流量收费。 |
官方PHP SDK | 差,依赖亚马逊http库,而不是PHP官方PEAR HTTP_Request2 | 差 |
Rewrite the official confusing PHP SDK of Alibaba Cloud Storage into PEAR, and then download it as an apk.
Then I want to migrate the picture server to cloud storage so that it does not occupy VPS bandwidth. Only then did I discover that Alibaba Cloud OSS only has the simplest file storage function and does not support image processing.
For example, the most commonly used functions of image servers:
1. Upload an original image and automatically generate various images of any resolution in real time
For example, the original picture
http://example.com/2.jpg
Then request any resolution, and the server will automatically generate and output it when requesting, such as
http://example.com/2.jpg?resolution=1280x720
2. Automatic format conversion
For example http://example.com/2.jpg?format=png
Since Alibaba Cloud Storage does not support the image function, it cannot be used. Consider migrating to Qiniu.
Refer to Qiniu official PHP SDK, rewrite it into PHP PEAR package, and find that Qiniu API is not REST.
API comparison is as follows:
阿里云存储 | 七牛云存储 | |
上传文件 | HTTP PUT 资源URI | HTTP POST up.qiniu.com |
删除文件 | HTTP DELETE 资源URI | HTTP POST rs.qbox.me |
认证 | HTTP header Authorization | 一会儿使用HTTP header Authorization,一会儿使用POST token |
Alibaba Cloud Storage API CURL demo:
Upload files:
curl -i -X <span '</span><span PUT</span><span '</span> -T <span '</span><span 1.jpg</span><span '</span> <span '</span><span http://com-163-sinkcup.oss.aliyuncs.com/1.jpg</span><span '</span> -H <span '</span><span Authorization: OSS asdf:qwer</span><span '</span> -H <span '</span><span Content-Type:image/jpeg</span><span '</span>
curl -i -X <span '</span><span DELETE</span><span '</span> <span '</span><span http://com-163-sinkcup.oss.aliyuncs.com/2.jpg</span><span '</span>
Qiniu Cloud Storage API CURL demo:
Upload files (it can be seen that Qiniu puts the bucket in the token authentication, which technically prevents Qiniu from achieving "public upload"):
curl -i -F <span '</span><span file=@2.jpg</span><span '</span> -F <span '</span><span token=asdf</span><span '</span> -F <span '</span><span key=2.jpg</span><span '</span> <span '</span><span http://up.qiniu.com/</span><span '</span>
curl -i -X <span '</span><span POST</span><span '</span> -H <span '</span><span Authorization: QBox asdf</span><span '</span> <span '</span><span http://rs.qbox.me/delete/com-163-sinkcup:1.jpg</span><span '</span>
It can be seen that Alibaba Cloud Storage is technically rigorous and uses standard REST. Qiniu no longer uses tokens in some places, but uses HTTP header Authorization, which may be being improved.
The picture function comparison is as follows:
Alibaba Cloud Storage | Qiniu
|
|||||||||||||
Automatically generate any resolution | None | Support | ||||||||||||
Automatically generate any format | None | Support | ||||||||||||
webp | None | Supported, can save a lot of app traffic |
Qiniu’s picture demo:
Original image 103KB: http://com-163-sinkcup.qiniudn.com/6ffe255fab20747c8872638870268703
Automatically generate jpg 79KB: http://com-163-sinkcup.qiniudn.com/6ffe255fab20747c8872638870268703?imageMogr/v2/auto-orient/thumbnail/1366x768/quality/80/format/jpg
Automatically generate webp 23KB: http://com-163-sinkcup.qiniudn.com/6ffe255fab20747c8872638870268703?imageMogr/v2/auto-orient/thumbnail/1366x768/quality/80/format/webp
Because the image function provided by Qiniu is extremely powerful, supporting webp is particularly important for saving traffic on the mobile Internet (Android and ios apps save 70% traffic), and Qiniu uses the Go language and wrote a book ("Go Language Programming》Douban), indicating that it is technically very strong and will support REST in the future, so I finally decided to use Qiniu Cloud Storage.
The PHP SDKs of Alibaba Cloud and Qiniu are both non-standard and cannot be used, so they can only be rewritten. I rewrote it, here it is:
Qiniu Cloud Storage PHP PEAR package download: http://www.cnblogs.com/sink_cup/p/PHP_PEAR_Services_Qiniu.html
Alibaba Cloud Storage PHP PEAR package download: http://www.cnblogs.com/sink_cup/p/PHP_PEAR_Services_Aliyun_OSS.html
1% of Alibaba Cloud Storage does not meet standards:
The custom HTTP header uses lowercase letters, which is inconsistent with HTTP common sense. For example, it is wrong for Alibaba Cloud to use x-oss-acl, and X-Oss-Acl should be used.

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
