Golang amazon s3视频上传出现奇怪错误

我使用Golang作为我的后端代码，我有一个允许人们上传图像和视频的应用程序。我有图像和视频工作，但现在由于某种原因，我得到了这个错误，这是一样的。我已经检查过了，因为返回的文件有一定的大小，所以视频正在转换，但由于某些原因，在上传视频时，我一直收到下面的错误。。。错误发生在下面的PutObject中，任何建议都会很好

func UploadStreamVideo(w http.ResponseWriter, r *http.Request) {
    r.ParseForm()

    var buf bytes.Buffer
    sess, _ := session.NewSession(&aws.Config{
        Region:      aws.String("us-west-2"),
        Credentials: credentials.NewStaticCredentials(aws_access_key_id, aws_secret_access_key, ""),
    })

    svc := s3.New(sess)

    file, handler, err := r.FormFile("file")
    if err != nil {
        log_errors("HomePage-UploadStreamImage: error receiving file", err.Error(), w)
        fmt.Println("Error Uploading Image")
        return
    }
    defer file.Close()
    println(handler.Filename) // I can see filename
    println(handler.Size)   // I also see the size here

    read_file, err := ioutil.ReadAll(file)

    if err != nil {
        log_errors("HomePage-UploadStreamImage")
        return
    }

    file.Read(read_file)
    fileBytes := bytes.NewReader(read_file)
    fileSize, err := buf.ReadFrom(file)
    if err != nil {
        log_errors("HomePage-UploadStreamImage")
    }

    fileType := http.DetectContentType(read_file)
    path := handler.Filename

    params := &s3.PutObjectInput{
        Bucket: aws.String("yisl"),
        Key:    aws.String(path),
        Body:   fileBytes,

        ContentLength: aws.Int64(fileSize),
        ContentType:   aws.String(fileType),
    }

     // This code below gives the error
    _, err = svc.PutObject(params)
    if err != nil {
        println(err.Error())
        log_errors("HomePage-UploadStreamImage")
        return
    }

    io.WriteString(w, "Done")
}

错误是：

您的错误消息有点混乱。你就是这么看的吗？或者这是两个错误（一个错误，后跟堆栈跟踪）？正如@Flimzy所说，整个事情有点混乱。所以我的建议是从一开始就开始稍微打扫一下。首先是

ioutil.ReadAll

，然后是

file.Read

（但是由于您是ioutil.ReadAll，所以光标位于最末尾，所以应该没有字节）。您不需要执行该过程来获取文件大小，因为您已经有了

handler.size

。查看PutObject的AWS S3文档（下面的链接），

主体是
io.readseek
和
r.FormFile（“文件”）时得到的
多部分.file
实现了
io.Reader
和
io.Seeker
，因此我认为您可以将
文件直接传递到
PutObject
。
