示例
普通回调
如果选择普通回调模式，则回调 URL 会接收到来自云点播的 HTTP 请求。请求采用 POST 方法，请求内容在 BODY 中，如下所示（省略了值为 null 的字段）。
{ "EventType":"ProcedureStateChanged", "ProcedureStateChangeEvent":{ "TaskId":"1256768367-Procedure-475b72xxxcb177t1", "Status":"FINISH", "ErrCode":0, "Message":"", "FileId":"5285890784246869930", "FileName":"动物世界", "FileUrl":"https://1256768367.vod2.myqcloud.com/xxx/xxx/xxx.mp4", "MetaData":{ "AudioDuration":59.990001678467, "AudioStreamSet":[ { "Bitrate":383854, "Codec":"aac", "SamplingRate":48000 } ], "Bitrate":1021028, "Container":"mov,mp4,m4a,3gp,3g2,mj2", "Duration":60, "Height":480, "Rotate":0, "Size":7700180, "VideoDuration":60, "VideoStreamSet":[ { "Bitrate":637174, "Codec":"h264", "Fps":23, "Height":480, "Width":640 } ], "Width":640 }, "MediaProcessResultSet":[ { "Type":"Transcode", "TranscodeTask":{ "Status":"SUCCESS", "ErrCode":0, "Message":"SUCCESS", "Input":{ "Definition":20 }, "Output":{ "Url":"https://1256768367.vod2.myqcloud.com/xxx/xxx/v.f20.mp4", "Size":4189073, "Container":"mov,mp4,m4a,3gp,3g2,mj2", "Height":480, "Width":640, "Bitrate":552218, "Md5":"eff7031ad7877865f9a3240e9ab165ad", "Duration":60.04700088501, "VideoStreamSet":[ { "Bitrate":503727, "Codec":"h264", "Fps":24, "Height":480, "Width":640 } ], "AudioStreamSet":[ { "Bitrate":48491, "Codec":"aac", "SamplingRate":44100 } ], "Definition":0 } } }, { "Type":"CoverBySnapshot", "CoverBySnapshotTask":{ "Status":"SUCCESS", "ErrCode":0, "Message":"SUCCESS", "Input":{ "Definition":10, "PositionType":"Time", "PositionValue":0 }, "Output":{ "CoverUrl":"http://1256768367.vod2.myqcloud.com/xxx/xxx/xxx.100_0.jpg" } } } ] }}
可靠回调
