用s3manager上传文件

Question

我正在尝试从我的网站下载一些文件，并将它们上传到amazons3。

这是我的代码：

import (
    "log"
    "net/http"

    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/credentials"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/s3/s3manager"
)

func main() {
    // Make a GET request to an image to be downloaded and uploaded to s3
    resp, err := http.Get("http://my-site.com/image.jpg")
    if err != nil {
        log.Fatal(err)
    }

    // Get the AWS credentials
    creds := credentials.NewSharedCredentials("/Users/name/.aws/credentials", "default")

    // Set up config
    config := &aws.Config{
        Region:      aws.String("US Standard"),
        Credentials: creds,
    }

    // Set up a new AWS session
    sess := session.New(config)

    // Set up a new s3manager client
    uploader := s3manager.NewUploader(sess)

    result, err := uploader.Upload(&s3manager.UploadInput{
        Body:   resp.Body,
        Bucket: aws.String("mimi-movies"),
        Key:    aws.String("mimi.jpg"),
    })
    if err != nil {
        log.Fatalln("Failed to upload", err)
    }

    log.Println("Successfully uploaded to", result.Location)
}

我一直得到一个零指针取消引用的运行时错误，但是由于某些原因，我认为它可能与ssl有关，但以下是整个错误：

Answer 1

aws-go-sdk上有一个bug，但解决方案是将该区域更改为“us 1”。

// Set up config
config := &aws.Config{
    Region:      aws.String("us-east-1"),
    Credentials: creds,
}

Answer 2

正如@user3666882所提到的，aws中存在bug，您可能应该检查您的区域。

在您的代码中，您已经编写了获得AWS证书的代码。

// Get the AWS credentials
    creds := credentials.NewSharedCredentials("/Users/name/.aws/credentials", "default")

您可以在您的终端中尝试这样的方法：

aws配置

并配置aws。

否则你可以用Minio。但是您必须将ACCESS_KEY_ID和SECRET_ACCESS_KEY放在代码中，这对生产使用非常不利。

 s3Client, err := minio.New("s3.amazonaws.com", "YOUR-ACCESSKEYID", "YOUR-SECRETACCESSKEY", false)

此外，您还可以使用外部API 毒蛇隐藏这些密钥。但我建议您使用正式的AWS作为Go。
