明确答案: Go Get 是一个命令行工具,用于管理 Go 模块及其依赖项。详细描述:Go Get 可用于获取 Go 模块,语法为:go get [-u] <module path>。可以指定特定模块版本:go get <module path>@<version>。使用 go get -u <module path> 更新已安装模块。通过 go mod tidy 删除不再使用的模块。
Go Get:获取和管理 Go 模块
简介
Go 语言提供了一种称为模块的机制,用于管理代码包及其依赖项。Go Get 是一个命令行工具,可用于获取、更新和管理 Go 模块。
安装 Go Get
Go Get 已包含在 Go 1.11 及更高版本中。要检查您使用的 Go 版本,请运行以下命令:
go version
如果没有安装 Go Get,您可以使用以下命令安装它:
go get golang.org/x/tools/cmd/goimports
获取模块
要获取模块,请使用以下语法:
go get [-u] <module path>
其中:
-u
选项更新已安装的模块的最新版本。<module path>
是模块的路径,例如github.com/user/mymodule
。
实战案例:安装 github.com/go-sql-driver/mysql
要安装用于连接 MySQL 数据库的 github.com/go-sql-driver/mysql
模块,请运行以下命令:
go get github.com/go-sql-driver/mysql
管理模块版本
您可以使用以下语法指定模块的特定版本:
go get <module path>@<version>
例如,要安装 github.com/user/mymodule
模块的 1.0.0 版本,请运行以下命令:
go get github.com/user/mymodule@v1.0.0
更新模块
要更新已安装的模块,请使用以下语法:
go get -u <module path>
删除模块
要删除模块,请使用以下语法:
go mod tidy
此命令将删除不再使用的模块。

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

Golang is better than C in concurrency, while C is better than Golang in raw speed. 1) Golang achieves efficient concurrency through goroutine and channel, which is suitable for handling a large number of concurrent tasks. 2)C Through compiler optimization and standard library, it provides high performance close to hardware, suitable for applications that require extreme optimization.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

Golang is better than Python in terms of performance and scalability. 1) Golang's compilation-type characteristics and efficient concurrency model make it perform well in high concurrency scenarios. 2) Python, as an interpreted language, executes slowly, but can optimize performance through tools such as Cython.
