🌄Upload Content Attachment

In this article, I would be showing you how to upload an attachment in a Confluence content using the "go-atlassian" library.

Step 1: Set up the project

1. Create a new directory for your project.

2. Open a terminal and navigate to the project directory.

3. Initialize a new Go module using the following command:

go mod init <module-name>

Step 2: Install the "go-atlassian" library

In the terminal, run the following command to install the "go-atlassian" library:

go get -v github.com/ctreminiom/go-atlassian

Step 3: Import the necessary packages

1. Create a new Go file (e.g., main.go) in your project directory.

2. Open the file and import the required packages:

package main

import (
	"github.com/ctreminiom/go-atlassian/confluence"
	"log"
	"os"
)

Step 4: Authenticate with Confluence

In the main function, create a new Confluence client and authenticate using your Atlassian URL, username, and API token:

func main() {

	atlassianHost := "https://<_jira_instance_>.atlassian.net"
	mailAddress := "<your_mail>"
	apiToken := "<your_api_token>"

	client, err := confluence.New(nil, atlassianHost )
	if err != nil {
		log.Fatal(err)
	}

	client.Auth.SetBasicAuth(mailAddress, apiToken)
}

Step 5: Upload an attachment to a Confluence page

• Define the necessary variables for the page ID, file path, and file name:

pageID := "76513281"
filePath := "confluence/mocks/mock.png"
fileName := "mock-00.png"

• Open the file using the provided file path:

absolutePath, err := filepath.Abs(filePath)
if err != nil {
	log.Fatal(err)
}

log.Println("Using the path", absolutePath)

reader, err := os.Open(absolutePath)
if err != nil {
	log.Fatal(err)
}

defer reader.Close()

• Upload the attachment using the Content.Attachment.Create()method and provide the page ID, file name, and file content:

attachmentsPage, response, err := client.Content.Attachment.Create(context.Background(), pageID, "current", fileName, reader)
if err != nil {

	if response != nil {
		if response.Code == http.StatusBadRequest {
			log.Println(response.Code)
		}
	}
	log.Println(response.Endpoint)
	log.Fatal(err)
}

log.Println("Endpoint:", response.Endpoint)
log.Println("Status Code:", response.Code)

for _, attachment := range attachmentsPage.Results {
	log.Println(attachment.ID, attachment.Title)
}

Make sure to replace <CONFLUENCE_PAGE_ID>, <FILE_PATH>, and <FILE_NAME> with the actual values for your use case.

Step 6: Run the program

1. Save the main.go file.

2. In the terminal, navigate to your project directory.

3. Execute the following command to run the program:

go run main.go

This will upload the specified file as an attachment to the Confluence page with the provided page ID.
