上传大文件到S3

Question

我的机器上有python2.7、pip和boto。你知道吗

我需要上传一个约400 MB的zip文件到S3存储桶。你知道吗

上载可以在小文件上工作，但在上载所需的400 MB文件时失败并出现此错误。 BotoServerError:400错误请求 我正在使用下面的代码。有什么想法吗？你知道吗

    def UploadFileToS3(self, zippedfile, aws_access_key_id, aws_secret_access_key, bucket, awsfolder, callback=None, md5=None, reduced_redundancy=False, content_type=None):

    #def UploadFileToS3(self, zippedfile, callback=None, md5=None, reduced_redundancy=False, content_type=None):

            # so we fall back on this            
            file.seek(0, os.SEEK_END)
            size = file.tell()

        conn = boto.connect_s3(aws_access_key_id, aws_secret_access_key)
        bucket = conn.get_bucket(bucket, validate=True)
        k = Key(bucket)
        #k.key = key


        filename = os.path.basename(zippedfile)
        k.key = awsfolder + "/" + filename

        # Rewind for later use
        file.seek(0)
    except Exception as ex:
        print "Error encountered while uploading to S3. " + unicode(ex)
