操作步骤

1. 获取用户Token，用于调用点播接口时进行认证鉴权。

   详细信息请参见构造请求。以“华北-北京四”为示例，若您需要调用其它区域的点播接口，请替换成对应区域的 IAM 终端节点。

   POST https://iam.cn-north-4.myhuaweicloud.com/v3/auth/tokens
   Content-Type: application/json
   
   {
     "auth": {
       "identity": {
         "methods": [
           "password"
         ],
         "password": {
           "user": {
             "name": "username", 
             "password": "password", 
             "domain": {
               "name": "domainname"   
             }
           }
         }
       },
       "scope": {
         "project": {
            "name": "projectname"
         }
       }
     }
   }

   如图2所示，红框中的信息为获取用户Token。

2. 调用创建媒资：上传方式接口，创建媒资，在请求头中增加“X-Auth-Token”字段，其中“Value”为步骤1获取的。

   POST https://vod.cn-north-4.myhuaweicloud.com/v1.0/{project_id}/asset
   
   {
   	"title": "test",
   	"description": "test",
   	"category_id": 87748, 
   	"video_name": "test.mp4",
   	"video_type": "MP4",
   	"cover_type": "PNG",
   	"tags":"mytags,test",
   	"auto_publish": 0,    
   	"template_group_name":"test",
   	"subtitles":[      
   		{	
   			"id":1,
   			"language":"CN", 
   			"type": "SRT", 
   			"md5": "SqcyFjJZoDZaP8oKIY6rgQ==",    
   			"description":"AAAAA" ,
   			"name":"cc.srt"
   		}  
   	],
   	"thumbnail":{
   		"type":"time",
   		"cover_position":1
   	
   	},
   	"review":{
   		"interval":10,
   		"politics":-1,
   		"terrorism":-1,
   		"porn":-1
   	}	
   }

   • “vod.cn-north-4.myhuaweicloud.com”为点播服务的终端节点，您可以在VOD终端节点中获取。
   • “category_id”为媒资分类ID。用户需要提前创建完成媒资分类，操作请参考创建媒资分类。
   • “template_group_name”为转码模板组名称。用户需要提前创建完成转码模板，操作请参考创建自定义转码模板。
     

     调用IAM接口的区域需与调用点播接口的区域一致，如调用“cn-north-4”区域的IAM接口获取用户Token，则该Token仅能用于调用“cn-north-4”区域点播接口的鉴权。

3. 在返回参数中获取“video_upload_url”，“cover_upload_url”和“subtitle_upload_urls”。

   {
     "asset_id": "3f40a2c7c60454f5f84381e0313ca230",
     "video_upload_url": "https://vod-bucket-81.obs.cn-north-4.myhuaweicloud.com:443/474bcff2992f4be5b883a2fb9cec7343/3f40a2c7c60454f5f84381e0313ca230/cdeda86cd1b7b3dd760a3ff28a5ee497.mp4?AWSAccessKeyId=BG923RWHL4HFXOGKCVAL&Expires=1560420274&Signature=9f%2BZcdD6SwjIU5ARHYiP6YY1Lyw%3D",
     "cover_upload_url": "https://vod-bucket-81.obs.cn-north-4.myhuaweicloud.com:443/474bcff2992f4be5b883a2fb9cec7343/3f40a2c7c60454f5f84381e0313ca230/cover/Cover0.png?AWSAccessKeyId=BG923RWHL4HFXOGKCVAL&Expires=1560420274&Signature=4Aa88NK%2By%2By1Xo0RvLpOvuaFCoE%3D",
     "subtitle_upload_urls": [
       "https://vod-bucket-81.obs.cn-north-4.myhuaweicloud.com:443/474bcff2992f4be5b883a2fb9cec7343/3f40a2c7c60454f5f84381e0313ca230/subtitle/1.srt?AWSAccessKeyId=BG923RWHL4HFXOGKCVAL&Expires=1560420274&Signature=l0UclE9yfaVrxkl0kaNnr%2BemG98%3D"
     ],
     "target": {
       "bucket": "vod-bucket-81",
       "location": "cn-north-4",
       "object": "474bcff2992f4be5b883a2fb9cec7343/3f40a2c7c60454f5f84381e0313ca230/cdeda86cd1b7b3dd760a3ff28a5ee497.mp4"
     }
   }

4. 使用PUT请求分别向“video_upload_url”，“cover_upload_url”和“subtitle_upload_urls”中上传音视频文件、封面图片和字幕文件。
   其中，请求头“Content-Type”需要根据上传的文件类型分别设置，如下所示：

   • 视频文件：video/视频格式，如：“video/mp4”。更多视频文件格式对应的请求头填写规则，请参见表1。
   • 音频文件：audio/音频格式，如：“audio/mp3”。更多音频文件格式对应的请求头填写规则，请参见表2。
   • 图片文件：image/图片格式，如：“image/png”。
   • 字幕文件：application/octet-stream。
