基于企鹅号的视频文件分片上传的实现流程，包含队列、文件切片、while 循环等
1、数据库结构的设计，一张资源表，一张企鹅号的视频文件分片上传表，一张企鹅号的事务表，结构如下：
28、asset：资源 Asset id 主键 channel_id 渠道ID channel_code 渠道代码，qq：企鹅号；wx：微信公众帐号 channel_type_id 渠道的类型ID channel_type_code 渠道的类型代码，qq_cw：企鹅号的内容网站应用；qq_tp：企鹅号的第三方服务平台应用；wx：微信公众帐号应用 source 来源，xContent：内容库；vms：视频管理系统；cms：内容管理系统；spider：自媒体 type 资源文件的类型，image：图片；video：视频 absolute_url 来源的资源文件的绝对URL relative_path 渠道发布的资源文件的相对路径 size 文件大小，单位(字节) task_id 任务ID channel_article_id 渠道的文章ID status 状态，0：禁用；1：启用 is_deleted 是否被删除，0：否；1：是 created_at 创建时间 updated_at 更新时间 deleted_at 删除时间
29、qq_video_multipart_upload：企鹅号的视频文件分片上传 QqCwVideoMultipartUpload id 主键 asset_id 资源ID qq_app_task_id 企鹅号的应用的任务ID qq_app_id 企鹅号的应用ID qq_app_type 企鹅号的应用类型，cw：内容网站应用；tp：第三方服务平台应用 size 视频文件大小，单位(字节) md5 视频文件MD5值 sha 视频文件SHA-1值 transaction_id 上传的唯一事务ID mediatrunk 视频 mediatrunk 文件 start_offset 分片的起始位置(从0开始计数) end_offset 分片的结束位置 vid 视频文件唯一标示ID status 状态，0：禁用；1：待上传；2：上传中；3：上传中(已失败)；4：已上传 is_deleted 是否被删除，0：否；1：是 created_at 创建时间 updated_at 更新时间 deleted_at 删除时间
30、qq_transaction：企鹅号的事务 QqTransaction id 主键 group_id 租户ID qq_app_task_id 企鹅号的应用的任务ID qq_app_id 企鹅号的应用ID qq_app_type 企鹅号的应用类型，cw：内容网站应用；tp：第三方服务平台应用 qq_article_id 企鹅号的文章ID qq_video_multipart_upload_id 企鹅号的应用的视频文件分片上传ID transaction_id 事务ID type 类型，1：文章；2：视频 transaction_ctime 事务创建时间 ext_err 扩展的错误 transaction_err_msg 事务的错误信息 article_abstract 文章摘要 article_type 文章类型，取值：普通文章，图文文章，视频文章，直播文章，RTMP直播文章 article_type_code 文章类型代码，normal：文章；multivideos：视频；images：组图；live：直播 article_url 文章快报链接 article_imgurl 文章封面图 article_title 文章标题 article_pub_flag 文章发布状态，取值：未发布，发布成功，审核中 article_pub_time 文章发布时间 article_video_title 视频文章标题 article_video_desc 视频文章描述 article_video_type 视频文章类型，视频 article_video_vid 视频文章的视频唯一ID task_id 任务ID status 状态，0：禁用；1：成功；2：失败；3：处理中 is_deleted 是否被删除，0：否；1：是 created_at 创建时间 updated_at 更新时间 deleted_at 删除时间
2、资源的上传是基于队列实现的，因此会先将资源数据存储至资源表，进而入上传资源的队列，再执行上传资源的作业
3、执行 1 次接口请求，此时资源表已经存在资源的相应数据，且入复制资源的队列
PS E:\wwwroot\channel-pub-api> ./yii copy-asset-queue/info --color=0 Jobs - waiting: 1 - delayed: 0 - reserved: 0 - done: 0
4、执行复制资源队列中的任务命令，会复制相应的资源，且将资源的相对路径存储至资源表中
PS E:\wwwroot\channel-pub-api> ./yii copy-asset-queue/run --verbose=1 --isolate=1 --color=0 2018-11-15 10:05:56 [pid: 23112] - Worker is started 2018-11-15 10:05:57 [1] common\jobs\CopyAssetJob (attempt: 1, pid: 23112) - Started 2018-11-15 10:06:08 [1] common\jobs\CopyAssetJob (attempt: 1, pid: 23112) - Done (11.394 s) 2018-11-15 10:06:08 [pid: 23112] - Worker is stopped (0:00:12)
5、复制资源队列中的任务执行成功后，会入上传资源的队列
PS E:\wwwroot\channel-pub-api> ./yii upload-asset-queue/info --color=0 Jobs - waiting: 1 - delayed: 0 - reserved: 0 - done: 0
6、上传资源的代码分为 2 个部分，一为文件切片，需要将视频资源文件切片为100M大小的小文件，\channel-pub-api\common\services\AssetService.php
/**
* 文件切片
* @param string $fileAbsolutePath 需要切片的文件的绝对路径
* 格式如下：E:/wwwroot/channel-pub-api/storage/spider/videos/切片文件.mp4
*
* @param int $size 104857600，单位为字节
*
* 生成文件列表如下：
* E:/wwwroot/channel-pub-api/storage/spider/videos/切片文件_0.mp4
* E:/wwwroot/channel-pub-api/storage/spider/videos/切片文件_1.mp4
*/
public static function cut($fileAbsolutePath, $size)
{
// 获取需要切片的文件的路径信息
$pathInfo = pathinfo($fileAbsolutePath);
$i = 0;
$handle = fopen($fileAbsolutePath, "rb");
while (!feof($handle)) {
$cutHandle = fopen($pathInfo['dirname'] . '/' . $pathInfo['filename'] . '_' . $i . '.' . $pathInfo['extension'], "wb");
fwrite($cutHandle, fread($handle, $size));
fclose($cutHandle);
unset($cutHandle);
$i++;
}
fclose($handle);
}
7、HTTP请求，企鹅号的内容网站应用的视频文件分片上传，\channel-pub-api\common\logics\http\qq_api\Video.php
<?php

9、执行上传资源队列中的任务命令，会切片文件，上传相应的资源，且更新企鹅号的视频文件分片上传表、新增企鹅号的事务
PS E:\wwwroot\channel-pub-api> ./yii upload-asset-queue/run --verbose=1 --isolate=1 --color=0 2018-11-15 11:02:29 [pid: 39632] - Worker is started 2018-11-15 11:02:30 [1] common\jobs\UploadAssetJob (attempt: 1, pid: 39632) - Started 2018-11-15 11:06:48 [1] common\jobs\UploadAssetJob (attempt: 1, pid: 39632) - Done (257.816 s) 2018-11-15 11:06:48 [pid: 39632] - Worker is stopped (0:04:19)
10、查看生成的切片小文件，由于切片大小为100M，396 MB (415,352,401 字节)的文件切片为4个小的文件，如图1
图1
11、上传成功后，分片的起始位置与分片的结束位置皆等于文件的大小：415352401，如图2
图2
12、在企鹅号后台查看我的素材，视频文件已经分片上传成功，如图3
图3
