Solve the problem of xxx is deprecated when go get
This article is introduced by the golang tutorial column to introduce to you the problem of ‘xxx is deprecated’ when go get occurs. I hope it will be helpful to friends in need!
Recently, I need to use protobuf for grpc when learning go. The protoc-gen-go package can generate golang's protobuf version protocol code
In the mac development environment, an error will be reported when using the following command to install the package
go get -u github.com/golang/protobuf/protoc-gen-go
The error content is the following:
The error message is that after version go1.17, the use of go get to install packages is not supported, but through go Install the package by install
Here I used my personal solution
Enter golang/protobuf to download the source code
- Enter the protobuf directory
- Enter the protoc-gen-go directory
- Run the command go build
- Run the command go install
Here is a brief introduction to go build and go install
go build
By go build plus the name of the Go source file to be compiled, we can get an executable file. By default, the name of this file is the name of the source file. Remove the .go suffix.
go install
Compared with the build command, the install command will also install the executable file or library file to the agreed directory after compiling the source code.
go installThe compiled executable file is named after the directory name (DIR) where it is located
go install installs the executable file to In the bin directory at the same level as src, the bin directory is automatically created by go install.
go install compiles the various packages that the executable file depends on and places them in the pkg directory at the same level as src. Next
At this time, the executable file of protoc-gen-go will exist in the /bin directory of GOPATH
Change $ The GOPATH/bin directory is added to the environment variable, so that subsequent commands generated by go install can be executed directly.
Now edit the /etc/profile file and add this text to the profile file. The $GOPATH variable here is the GOPATH path of your local GO
export PATH="$PATH: $GOPATH/bin" >> /etc/profile
The problem is solved! You can export golang's protocbuf protocol code through the command protoc --go_out=plugins=grpc:. *.proto

Reading and writing files safely in Go is crucial. Guidelines include: Checking file permissions Closing files using defer Validating file paths Using context timeouts Following these guidelines ensures the security of your data and the robustness of your application.

How to configure connection pooling for Go database connections? Use the DB type in the database/sql package to create a database connection; set MaxOpenConns to control the maximum number of concurrent connections; set MaxIdleConns to set the maximum number of idle connections; set ConnMaxLifetime to control the maximum life cycle of the connection.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.

The FindStringSubmatch function finds the first substring matched by a regular expression: the function returns a slice containing the matching substring, with the first element being the entire matched string and subsequent elements being individual substrings. Code example: regexp.FindStringSubmatch(text,pattern) returns a slice of matching substrings. Practical case: It can be used to match the domain name in the email address, for example: email:="user@example.com", pattern:=@([^\s]+)$ to get the domain name match[1].

Go framework development FAQ: Framework selection: Depends on application requirements and developer preferences, such as Gin (API), Echo (extensible), Beego (ORM), Iris (performance). Installation and use: Use the gomod command to install, import the framework and use it. Database interaction: Use ORM libraries, such as gorm, to establish database connections and operations. Authentication and authorization: Use session management and authentication middleware such as gin-contrib/sessions. Practical case: Use the Gin framework to build a simple blog API that provides POST, GET and other functions.

Using predefined time zones in Go includes the following steps: Import the "time" package. Load a specific time zone through the LoadLocation function. Use the loaded time zone in operations such as creating Time objects, parsing time strings, and performing date and time conversions. Compare dates using different time zones to illustrate the application of the predefined time zone feature.
