Tencent Cloud Object Storage Golang SDK

Golang has become increasingly popular among developers due to its simplicity, concurrency support, and strong ecosystem. With the rise of cloud computing, developers need efficient and reliable ways to store and manage large amounts of data. Tencent Cloud Object Storage offers a secure and scalable solution for storing and retrieving data in the cloud. In this article, we will explore how to use the Tencent Cloud Object Storage Golang SDK to interact with the storage service.

Installation

To get started with the Tencent Cloud Object Storage Golang SDK, you need to install the package using the following command:

go get -u github.com/tencentyun/cos-go-sdk-v5

This will download and install the SDK and its dependencies.

Initializing the Client

Before you can start using the SDK, you need to create a client object. The client object allows you to interact with the Tencent Cloud Object Storage service.

import (
    "context"
    "github.com/tencentyun/cos-go-sdk-v5"
)

func main() {
    secretID := "YOUR_SECRET_ID"
    secretKey := "YOUR_SECRET_KEY"
    bucket := "YOUR_BUCKET_NAME"
    region := "YOUR_REGION" // e.g. ap-guangzhou
    u, _ := url.Parse(fmt.Sprintf("https://%s.cos.%s.myqcloud.com", bucket, region))
    
    client := cos.NewClient(&cos.BaseURL{BucketURL: u}, &http.Client{
        Transport: &cos.AuthorizationTransport{
            SecretID:  secretID,
            SecretKey: secretKey,
        },
    })

    // You can now use the client object to interact with the Tencent Cloud Object Storage service
}

Uploading Objects

One of the main features of the Tencent Cloud Object Storage Golang SDK is the ability to upload objects to the storage service.

package main

import (
    "context"
    "github.com/tencentyun/cos-go-sdk-v5"
    "os"
)

func main() {
    client := getClient() // Get the client object as shown above
    
    file, _ := os.Open("path/to/file") // Open the file to upload
    key := "path/to/remote/key"       // Specify the remote key for the uploaded object
    
    _, err := client.Object.Put(context.TODO(), key, file, nil)
    if err != nil {
        // Handle the error
    }
}

Downloading Objects

In addition to uploading objects, you can also download objects from the Tencent Cloud Object Storage service using the Golang SDK.

package main

import (
    "context"
    "github.com/tencentyun/cos-go-sdk-v5"
    "os"
)

func main() {
    client := getClient() // Get the client object as shown above
    
    key := "path/to/remote/key"               // Specify the remote key of the object to download
    localFile, _ := os.Create("local/file")    // Create a local file to save the downloaded object
    
    _, err := client.Object.GetToFile(context.TODO(), key, localFile, nil)
    if err != nil {
        // Handle the error
    }
}

Deleting Objects

You can also delete objects stored in the Tencent Cloud Object Storage service using the Golang SDK.

package main

import (
    "context"
    "github.com/tencentyun/cos-go-sdk-v5"
)

func main() {
    client := getClient() // Get the client object as shown above
    
    key := "path/to/remote/key"             // Specify the remote key of the object to delete
    
    _, err := client.Object.Delete(context.TODO(), key, nil)
    if err != nil {
        // Handle the error
    }
}
