amazon-web-services - Golang 中 AWS S3 中的 NoCredentialproviders

Question

我在 Golang 工作，现在我试图将图像上传到 AWS S3，但我得到:

NoCredentialProviders: no valid providers in chain. Deprecated.
    For verbose messaging see aws.Config.CredentialsChainVerboseErrors

我的代码是这样的:

func firstFunction(){
    //Connect to S3
    AWSsession, err := ConnectAWS()
    if err != nil {
        fmt.Println("Error Connecting to AWS S3")
    }

    GetSingleMedia(AWSsession)
}

func ConnectAWS()(*session.Session, error){

    //Create S3 Session
    AWSsession, err := session.NewSession(&aws.Config{
        Region: aws.String("us-west-2")},
    )

    if err != nil {
        fmt.Println("Error AWS:", err.Error())
    }

    return AWSsession,err
}

func GetSingleMedia(...someparams,AWSsession *session.Session){
            //o.Blob is correct, this is valid
            data, err := ioutil.ReadAll(bytes.NewReader(o.Blob))
            //Store: bytes.NewReader(o.Blob)
            UploadImage(AWSsession,bytes.NewReader(o.Blob),bucket,"SomeID")
}

func UploadImage(AWSsession *session.Session,reader *bytes.Reader,bucket string, key string) (*s3manager.UploadOutput,error){

    uploader := s3manager.NewUploader(AWSsession)

    result, err := uploader.Upload(&s3manager.UploadInput{
        Body : reader,
        Bucket: aws.String(bucket),
        Key : aws.String(key),
    })

    if err != nil {
        fmt.Println("Error uploagin img: ",err.Error())
    }


    return result,err
}

此外，我已将凭证放在 /home/myuser/.aws/ 下，有一个凭证文件，我在创建 session 时没有收到任何错误，那么，可能是什么问题？在UploadImage中触发错误

编辑:

目前在我的凭据文件中:

[default]
awsBucket = "someBucket"
awsAccessKey = "SOME_ACCESS_KEY"
awsSecretKey = "SOME_AWS_SECRET_KEY"

我是否可以更改任何权限或其他内容？

我建议您按照此处的指南进行操作:http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html

此命令将要求您提供访问/ key 并以正确的格式写入它们:

aws configure

您的 credentials 文件格式似乎有误。正确的格式应该是这样的:

[default]
aws_access_key_id = SOME_ACCESS_KEY
aws_secret_access_key = SOME_AWS_SECRET_KEY
