Using Thrift for service governance in Beego

With the gradual maturity and popularity of service-oriented architecture and microservice architecture, service governance has become an increasingly important issue. In Golang, Beego, as a popular web framework, actually provides some usable service governance methods, including integration with Thrift. Let's discuss in detail how to use Thrift for service governance in Beego.

1. What is Thrift

Thrift is a cross-language data transmission framework open sourced by Facebook. It can be used to define and generate a data encoding, decoding and service for remote calls. acting. Different from other RPC frameworks, Thrift adopts a data format, structure and code generation method different from the language itself, and realizes the ability of data interaction between different platforms, which means that we can use it to solve communication problems between different languages. .

The advantages of Thrift are language independence, cross-platform, wide range of programmable languages, concise code generation, good performance, etc.

2. Thrift in Beego

Although the Beego framework does not officially provide a framework for service governance, Thrift can still be used for service governance within it. Using Thrift, we can quickly implement a distributed service architecture in Beego.

Configure the running environment

1. Get the Thrift code package in Beego

Enter the following command in the command line window:

go get git.apache.org/thrift.git/lib/go/thrift

2. Add the Thrift service address and port number in the project configuration file

In the Beego project, we A thrift configuration needs to be added to the configuration file. Add the following configuration to the app.conf file:

[thrift]
Addr = "127.0.0.1:9090"

3. Add the Thrift IDL file to the project

We can create a new thrift folder in the project to store the thrift interface definition Language files. For example, we create a calculator.thrift file in the project and define the calculator service interface in it:

enum Operation {
    ADD = 1,
    SUBTRACT = 2,
    MULTIPLY = 3,
    DIVIDE = 4
}

struct Work {
    1: i32 num1,
    2: i32 num2,
    3: Operation op,
    4: i32       client_id,
}

service Calculator {
    i32 calculate(1: Work work),
}

A Calculator service is defined in it, and a calculate method is encapsulated in the service to receive a Work Structure parameters and returns an integer result.

4. Compile the Thrift IDL file into the target language file

We need to generate the code file of the corresponding language from the thrift interface definition language file in the project. For example, in our project, we need to use the thrift tool to compile calculator.thrift into a Go language file. First, we need to run the following command in the command line:

thrift --gen go calculator.thrift

This command will generate a gen-go folder in the current directory, which contains the Go language file generated by the calculator.thrift file.

Create Thrift service

In Beego, we can use Thrift to create a service and implement the methods in the interface file.

import (
    "git.apache.org/thrift.git/lib/go/thrift"
    "xxxx/thrift/gen-go/calculator"
)

func thriftServer() {

    addr := beego.AppConfig.String("thrift::Addr")

    socket, err := thrift.NewTServerSocket(addr)
    if err != nil {
        panic(err)
    }

    handler := new(calculator.CalculatorHandler)
    processor := calculator.NewCalculatorProcessor(handler)

    server := thrift.NewTSimpleServer4(processor, socket, transportFactory, protocolFactory)
    server.Serve()
}

In the above code, we first obtain the address corresponding to thrift from the configuration file, use NewCalculatorProcessor to encapsulate the service proxy in the code generated by the thrift tool, and wrap it through the Thrift.NewTSimpleServer4 method Become a server to monitor.

Start the service

We can create the Thrift server through goroutine in Beego's main.go and monitor it:

func main() {
    go thriftServer()
    beego.Run()
}

3. Thrift advantages and applicable scenarios

Using Thrift for service management has the following advantages:

1. Cross-language - Thrift is designed to handle communication between different programs (even in different languages)
2. Easy to maintain - can automatically generate code, no need to manually write a lot of network transmission layer code
3. High performance - Thrift uses binary format for network transmission, which saves bandwidth and can also be compressed Technology further improves efficiency
4. Diverse implementation methods - Thrift is similar to other RPC frameworks. There are corresponding client and server implementations such as C, Java, and Python, and it is not limited to Java and other fields. It has high Scalability

Thrift is suitable for the following scenarios:

1. Distributed applications - Thrift can facilitate cross-language service calls and is suitable for distributed application development
2. Real-time services - Thrift is based on the TCP/IP protocol, and is more efficient in processing requests and responses. It is suitable for scenarios related to real-time services.
3. Restrictions on high transmission costs - Thrift adopts Binary format transmission makes the transmission cost relatively low and can effectively reduce bandwidth usage

4. Summary

Using Thrift for service management in Beego greatly facilitates developers The work realizes cross-language service calls and reduces the maintenance cost of the entire system. At the same time, Thrift, as a cross-language data transmission framework, is more common when implementing truly distributed applications and Real-time services. Therefore, we can learn to master Thrift for service development and expand our skill tree.
