golang process approval framework

With the increasing development of enterprises, process approval has become an extremely necessary part of the management process. With the advancement of technology, various process approval frameworks have emerged one after another, including the golang process approval framework. As one of the most popular programming languages ​​currently, golang is highly praised for its high performance and concurrency and has been widely used in enterprise development. So, let’s take a closer look at the golang process approval framework.

What is the process approval framework?

The process approval framework, as the name suggests, is a tool or system used to process process approval. It can be used to handle various types of workflows and user behaviors, thereby improving work efficiency. In enterprise management, the process approval framework can be used to follow up and supervise the daily work of employees to ensure that the work proceeds smoothly.

Advantages of golang process approval framework

As an efficient concurrency programming language, golang is just suitable for high-concurrency approval processes, which is why the golang process approval framework is so popular. one. Different from the traditional process approval framework, the golang process approval framework has independent Goroutine in multi-threads, which can easily implement concurrent and asynchronous processing, further improving the speed of approval processing.

In addition, the golang process approval framework also has the following advantages:

1. Simple and easy to learn: golang has a concise syntax and is easy to learn, so it is very suitable for novices to use.

2. Efficiency: golang is a compiled language that is more efficient than interpreted languages ​​in terms of operating efficiency.

3. Supports multiple platforms: golang can run on multiple platforms such as Linux, Windows and Mac OS, and is quite efficient.

4. Function support: golang functions support variables created in memory, which can be interrupted and restarted at any time, which is very useful in handling the approval process.

5. Lower space usage: golang has a lower space usage and can quickly build efficient web applications and APIs.

Use of golang process approval framework

The use of golang process approval framework can be divided into three parts:

1.Document model definition

In use When using the golang process approval framework, you must first define the document model of the approval process, including document fields, document status, document comments, etc. A simple sample code is as follows:

type Document struct {
    DocId int `json:"doc_id"`
    status int `json:"status"`
    comments []Comment `json:"comments"`
}

type Comment struct {
    commentId int `json:"comment_id"`
    comment string `json:"comment"`
}

In the document model definition, we specify various attributes of the document, such as document number, document status, document comments, etc.

2. Workflow definition

Workflow definition is the core part of the golang process approval framework. Workflow definition refers to the configuration items that indicate each step in the workflow, such as approvers, operation types, status transitions, etc.

A simple sample code is as follows:

package main

import (
    "github.com/qiaoba0718/go-workflow"
)

func main() {
    docWorkflow := flow.NewFlow("doc_flow")
    docWorkflow.AddNode("start", flow.NodeTypeStart)
    docWorkflow.AddNode("approver1", flow.NodeTypeTask)
    docWorkflow.AddNode("approver2", flow.NodeTypeTask)
    docWorkflow.AddNode("end", flow.NodeTypeEnd)

    docWorkflow.AddEdge("start", "approver1", "to_approver1")
    docWorkflow.AddEdge("approver1", "approver2", "to_approver2")
    docWorkflow.AddEdge("approver2", "end", "to_end")

    docWorkflow.Start()
}

In this sample code, we define a process named "doc_flow", which includes four steps: start, approver 1 , Approver 2 and End.

3. Business logic implementation

After completing the document model and workflow definition, we can start to implement the business logic. When implementing business logic, we need to use the previously defined document model and workflow definition. A simple example code is as follows:

package main

import (
    "github.com/qiaoba0718/go-workflow"
)

func main() {
    doc := &Document{
        DocId: 1,
    }

    docWorkflow := flow.GetFlow("doc_flow")
    docWorkflow.StartDocument(doc)

    docStatus, _ := docWorkflow.GetStatus(doc)
    fmt.Printf("The document status is: %d
", docStatus)

    docWorkflow.SubmitTask(doc, "approver1", "approved")
    docStatus, _ := docWorkflow.GetStatus(doc)
    fmt.Printf("The document status is: %d
", docStatus)

    if docStatus == 2 {
        docWorkflow.SubmitTask(doc, "approver2", "approved")
    }
    docStatus, _ := docWorkflow.GetStatus(doc)
    fmt.Printf("The document status is: %d
", docStatus)

    docWorkflow.EndDocument(doc)

    docStatus, _ := docWorkflow.GetStatus(doc)
    fmt.Printf("The document status is: %d
", docStatus)
}

In this code example, we create a document named "doc" and use the "doc_flow" workflow in the workflow definition to process the document. During the processing, we used some methods, such as obtaining document status, submitting tasks and ending documents, to automate the entire process.

Summary

In general, the golang process approval framework is an efficient and easy-to-use process approval tool. It can significantly improve the efficiency of enterprise management and make various work processes smoother and more efficient. specification. Although using the golang process approval framework requires some technical foundation, as long as you master its basic knowledge, you can quickly implement various process approval requirements and improve work efficiency.
