在GO中使用AWS SDK V2上传图像失败

Question

我正在使用AWS S3服务上传图像。昨天，我将SDK v1更新到v2，发现图像上传失败，出现以下错误：

operation error S3: PutObject, https response error StatusCode: 403, RequestID: XXXXXXXXXXX, HostID: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX, api error SignatureDoesNotMatch: The request signature we calculated does not match the signature you provided. Check your key and signing method.

[default]
aws_access_key_id = XXXXXXXXXXXXXXXXXXX
aws_secret_access_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXx

package main

import (
    "context"
    "fmt"
    "io"
    "net/http"

    "github.com/aws/aws-sdk-go-v2/aws"
    awsconfig "github.com/aws/aws-sdk-go-v2/config"
    "github.com/aws/aws-sdk-go-v2/feature/s3/manager"
    "github.com/aws/aws-sdk-go-v2/service/s3"
)

func main() {
    fileName := "test123.jpg"
    filePath := "/BUCKET_NAME/uploads/aman/2021/6/25/"

    res, err := http.Get("https://images.app.goo.gl/mpQ5nXYXjdUMKGgW7")
    if err != nil || res.StatusCode != 200 {
        // handle errors
    }
    defer res.Body.Close()
    UploadFileInS3Bucket(res.Body, fileName, filePath)
}

func UploadFileInS3Bucket(file io.Reader, fileName, filePath string) {
    cfg, err := awsconfig.LoadDefaultConfig(context.TODO(),
        awsconfig.WithRegion("REGION"),
    )
    client := s3.NewFromConfig(cfg)
    uploader := manager.NewUploader(client)
    uploadResp, err := uploader.Upload(context.TODO(), &s3.PutObjectInput{
        Bucket:      aws.String(filePath),
        Key:         aws.String(fileName),
        Body:        file,
        ContentType: aws.String("image"),
    })
    fmt.Println(uploadResp)
    fmt.Println(err)
}

在花了几天时间之后，我了解到SDK V2对于Bucket和Key字段采用以下格式：

fileName := "uploads/2021/6/25/test123.jpg"
filePath := "BUCKET_NAME"

基本上，对于这些字段，在SDK V1和V2中存在反之亦然的行为。上面是V2。以下是V1:

fileName := "test123.jpg"
filePath := "/BUCKET_NAME/uploads/2021/6/25/"
