使用 Youtube REST API 上传视频失败

Question

我正在尝试通过 Swift 从 ios 应用程序使用 YouTube 的 REST API 将视频上传到 YouTube，但我很难弄清楚该怎么做。我已使用以下代码从应用程序在 youtube 上上传视频。

func postVideoToYouTube(uploadUrl: String, videoData: Data, title: String, description: String, callback: @escaping PostVideoCallback){

    if (self.authorizer != nil) && (self.authorizer?.canAuthorize)! {

        self.servive?.apiKey = kGoogleAPIKey
        self.servive?.authorizer = authorizer

        let status = GTLRYouTube_VideoStatus()
        status.privacyStatus = "public"

        let snippet = GTLRYouTube_VideoSnippet()
        snippet.title = title
        let desc = description
        if desc.count > 0 {
            snippet.descriptionProperty = desc
        }
        var video = GTLRYouTube_Video()
        video.status = status
        video.snippet = snippet

        //  ---------------------

        let accessToken = UserDefaults.standard.string(forKey: kAccessToken) ?? ""
        let headers: HTTPHeaders = ["Authorization": "Bearer \(accessToken)"]

        Alamofire.upload(
            multipartFormData: { multipartFormData in

                let metadata = "{'snippet':{'title' : '\(title)', 'description': '\(description)'}}".data(using: .utf8, allowLossyConversion: false)!
                multipartFormData.append(metadata, withName: "snippet", mimeType: "application/json")
                multipartFormData.append(videoData, withName: "video", fileName: "demo2.mov", mimeType: "application/octet-stream")
        },


            to: "https://www.googleapis.com/upload/youtube/v3/videos?part=snippet",
            headers: headers,
            encodingCompletion: { encodingResult in

                switch encodingResult {

                case .success(let upload, _, _):

                    upload.responseJSON { response in

                        print(response.result.value)

                        do {
                            let jsonData = try JSONSerialization.jsonObject(with: response.data!, options: .allowFragments) as! JSON


                        } catch {
                            print("error serializing JSON: \(error)")

                            callback("", false)

                        }

                        print("Success")

                    }
                case .failure(_):
                    print("Failure")

                    callback("", false)

                }
        })


    } 
}

我收到了来自 Youtube 的以下回复

`Optional({
    etag = "\"XI7nbFXulYBIpL0ayR_gDh3eu1k/CAh7qTdnefHn2x9Fdt7z11TW1HM\"";
    id = muradZ51g78;
    kind = "youtube#video";
    snippet =     {
        categoryId = 22;
        channelId = UCfI1223CGZiSGVKhapRfc4Q;
        channelTitle = "Khushbu Desai";
        description = Test;
        liveBroadcastContent = none;
        localized =         {
            description = Test;
            title = Video;
        };
        publishedAt = "2018-10-10T07:09:40.000Z";
        thumbnails =         {
            default =             {
                height = 90;
                url = "https://i.ytimg.com/vi/muradZ51g78/default.jpg";
                width = 120;
            };
            high =             {
                height = 360;
                url = "https://i.ytimg.com/vi/muradZ51g78/hqdefault.jpg";
                width = 480;
            };
            medium =             {
                height = 180;
                url = "https://i.ytimg.com/vi/muradZ51g78/mqdefault.jpg";
                width = 320;
            };
        };
        title = Video;
    };
})
Success`

但我没有在我的频道上找到该视频。因为我在 youtube Studio 上收到视频失败

Answer 1

这通常有两个原因：

1. 如果视频太大，有时上传时可能会丢失少量数据包。这将导致视频编码失败。

2. 确实可以正确上传，但在 youtube 端视频编码失败。

可以检查一些东西来调试/修复问题：

1. 您在响应中收到了视频的 ID。通过 Id 进行 get 调用，并检查响应中是否提到了失败原因。

2. 如果视频文件很大，那么最好选择chunk 上传而不是分段上传。
