oss开发版续点上传修改

从 create_mpu_object   上传修改，坑爹啊，弄了好久
====修改部分，以下========
// 初始化multipart
        if (isset($options['uploadId'])){
            $uploadId = $options['uploadId'];
        }else{
            //初始化
            $upload = $this->initiate_multipart_upload($bucket, $object);

                throw new OSS_Exception('Init multi-part upload failed...');
            }
            $xml = new SimpleXmlIterator($upload->body);
            $uploadId = (string)$xml->UploadId;
        }        

        // 或的分片
        $pieces = $this->get_multipart_counts($upload_filesize, (integer) $options[self::OSS_PART_SIZE]);

        $uploadResList = array();
        $upload_part_result = true;
        $upload_parts = array();
        if (isset($options['upload_parts'])) {

        }

        foreach ($pieces as $i => $piece){
            // if ($i==1) {//人为掏出异常，测试用
            //     throw new Exception(serialize($uploadResList), 1);
            // }
            if (isset($options['upload_parts']['PartNumber'])&&$options['upload_parts']['PartNumber']>=($i+1)) {
                continue;
            }
            $response_temp =  $this->upload_part($bucket, $object, $uploadId, array(
                //'expect' => '100-continue',
                self::OSS_FILE_UPLOAD => $options[self::OSS_FILE_UPLOAD],
                'partNumber' => ($i + 1),
                self::OSS_SEEK_TO => $upload_position + (integer) $piece[self::OSS_SEEK_TO],
                self::OSS_LENGTH => (integer) $piece[self::OSS_LENGTH],
            ));


            $upload_part_result = $upload_part_result && $response_temp->isOk();
            
            if(!$upload_part_result){
                throw new OSS_Exception(($i + 1).'any part upload failed...,pls try again');
            }

            $upload_parts[] = array(
                'PartNumber' => ($i + 1),
                'ETag' => (string) $response_temp->header['etag']
            );        

            //续点上传 上传参数
            $uploadResList['partNumber'] = ($i+1);
            $uploadResList['uploadId'] = $uploadId;
            $uploadResList['OSS_LENGTH'] = $piece[self::OSS_LENGTH];
            $uploadResList['OSS_SEEK_TO'] = $piece[self::OSS_SEEK_TO];
            $uploadResList['upload_parts'] = $upload_parts;
        }
        
        // $upload_parts = array();
        // $upload_part_result = true;
        
        // foreach ($response_upload_part as $i=>$response){
        //     $upload_part_result = $upload_part_result && $response->isOk();
        // }
        
        // if(!$upload_part_result){

        // }
