Question

我正在使用react-s3-uploader将文件上传到S3存储桶。所有文件类型和文件大小都可以执行mp3和m4a文件。大型mp4文件上传没有问题，图像，文本等。我甚至将mp3的文件扩展名更改为mp4并上传。但是，每次我尝试上传mp4或m4a S3时都会返回 SignatureDoesNotMatch 错误：

<Error>
<Code>SignatureDoesNotMatch</Code>
<Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message>

</Error>

以下是客户端和服务器的代码段。

JS react-s3-uploader代码段：

onDrop(acceptedFiles,rejectedFiles){
    var s3u = new S3Upload({
      files: acceptedFiles,
      signingUrl:this.uploadOptions.signingUrl,
      uploadRequestHeaders: { 'x-amz-acl': 'private' },
      onProgress:this.handleUploadProgress.bind(this),
      onError:this.handleUploadError.bind(this),
      onFinishS3Put:this.handleFinishedUpload.bind(this),
    });
    this.setState({files:acceptedFiles});
  }

Django终止获取签名的网址摘要：

conn = boto.connect_s3(settings.AWS_ACCESS_KEY_ID, settings.AWS_SECRET_ACCESS_KEY)
        object_name = request.GET['objectName']
        key_name = ('generic_video/' +str(ru.customer.pk)+'/'+ object_name).encode('utf-8')
        content_type = mimetypes.guess_type(object_name)[0]
        signed_url = conn.generate_url(

            key_name,

        return HttpResponse(json.dumps({'signedUrl': signed_url}))

上传mp3有什么特别的技巧吗？我觉得我错过了一些简单的东西？

SignatureDoesNotMatch将mp3 / m4a文件上传到S3但上传所有其他文件时出错
