示例3：获取媒资详情
场景描述
若您需要查询一个或多个媒资的基本信息、转码文件生成信息、截图信息及审核信息，您可以调用VOD API进行查询。
本章节指导用户如何使用API调用的方式获取存储在VOD中的媒资的详情信息。
操作步骤
- 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1所示，红框中的信息为获取用户Token。 - 调用查询媒资信息接口，查询媒资详情信息。
- 选择GET请求方法并输入URI。
https://{endpoint}/v1.0/{project_id}/asset/details?asset_id=41cff636d5b12a51e7eb2838bbf45201&categories=base_info,transcode_info&thumbnail_info,review_info“categories”为查询媒资信息的类型，您可以选择一个或者多个类型进行查询，具体取值如下所示：- base_info：查询媒资基本信息，包含媒资标题、分类、描述、文件类型、原始文件地址等。
- transcode_info：查询媒资转码文件信息，包含使用的转码模板、转码后的媒资信息等。
- thumbnail_info：查询截图信息，包含截图状态、截图存储地址等。
- review_info：审核信息，包含审核是否通过，文本审核结果、封面审核结果和视频审核结果等。
仅转码、截图或审核成功时，才可查询到对应的转码信息、截图信息和审核信息。
- 请求消息头中增加“X-Auth-Token”，值设置为步骤1中获取的用户Token。
- 请求响应成功后，返回媒资详情信息。
