Course Introduction：Core points Flysystem provides an abstraction layer for multiple file systems, allowing developers to focus on advanced operations such as read, write, and directory organization without worrying about the details of the underlying storage system. Flysystem simplifies the process of switching between different storage systems, making it easier to move or copy data from one system to another without having to rewrite a lot of application code. Flysystem supports a variety of storage systems, including local directories, Dropbox, Amazon S3, Cloud Files, FTP, and SFTP, and treats them all as local systems, making the process of saving files independent of the storage system used. Flysystem

Course Introduction：To get Laravel to collaborate with AmazonS3, you need to install AWSSDK, configure credentials, set up the file system, and check permissions. 1. Install AWSSDK: Run composerrequireleague/flysystem-aws-s3-v3. 2. Configure AWS credentials in the .env file and fill in the corresponding information. 3. Add S3 driver configuration in config/filesystems.php and use environment variables to avoid hard coding. 4. Set the default disk or explicitly call S3 when needed. 5.

Course Introduction：Security issues should be paid attention to when uploading Laravel files. 1. The allowed file type and size limits must be set, the file format is verified using image and mimes rules and preventing file disguising. 2. Rename the file using uniqid() or UUID to avoid conflict and guess attacks and prevent path traversal risks. 3. Make sure that the upload directory is not in the web root directory, disable script execution permissions in the server configuration or return file content through the controller. 4. Optionally use third-party storage such as AWSS3 and Alibaba Cloud OSS to improve security, and achieve better access control and high availability through Flysystem configuration drivers, but the deployment complexity and cost need to be weighed.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
