Golang 上传远程 URL 图片到 Minio 存储

你可以使用以下代码将远程 URL 图片文件上传到 Minio：

package main

import (
	"fmt"
	"io/ioutil"
	"net/http"
	"os"

	"github.com/minio/minio-go/v7"
	"github.com/minio/minio-go/v7/pkg/credentials"
)

func main() {
	// Initialize Minio client object.
	endpoint := 'play.min.io'
	accessKeyID := 'Q3AM3UQ867SPQQA43P2F'
	secretAccessKey := 'zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG'
	useSSL := true
	minioClient, err := minio.New(endpoint, &minio.Options{
		Creds:  credentials.NewStaticV4(accessKeyID, secretAccessKey, ''),
		Secure: useSSL,
	})
	if err != nil {
		fmt.Println(err)
		return
	}

	// Download image from remote URL.
	url := 'https://www.example.com/image.jpg'
	response, err := http.Get(url)
	if err != nil {
		fmt.Println(err)
		return
	}
	defer response.Body.Close()
	data, err := ioutil.ReadAll(response.Body)
	if err != nil {
		fmt.Println(err)
		return
	}

	// Upload image to Minio.
	bucketName := 'testbucket'
	objectName := 'image.jpg'
	contentType := 'image/jpeg'
	_, err = minioClient.PutObject('testbucket', objectName, bytes.NewReader(data), int64(len(data)), minio.PutObjectOptions{
		ContentType: contentType,
	})
	if err != nil {
		fmt.Println(err)
		return
	}

	fmt.Printf('Successfully uploaded %s to %s/%s\n', objectName, bucketName, objectName)
}

请注意，此示例代码假设您已安装minio-go库并导入它。此外，您需要替换accessKeyID，secretAccessKey，endpoint，bucketName和objectName变量的值以适应您的Minio实例和存储桶。
