swift - 使用 Swift 通过 REST API 为 youtube 上传设置片段数据

Question

我能够使用以下代码通过他们的 REST API 将视频成功上传到 youtube:

func postVideoToYouTube(token: String, callback: Bool -> Void){

let headers = ["Authorization": "Bearer \(token)"]

let path = NSBundle.mainBundle().pathForResource("video", ofType: "mp4")
let videodata: NSData = NSData.dataWithContentsOfMappedFile(path!)! as! NSData
upload(
    .POST,
    "https://www.googleapis.com/upload/youtube/v3/videos?part=id",
    headers: headers,
    multipartFormData: { multipartFormData in
        multipartFormData.appendBodyPart(data: videodata, name: "video", fileName: "video.mp4", mimeType: "application/octet-stream")
    },
    encodingCompletion: { encodingResult in
        switch encodingResult {
        case .Success(let upload, _, _):
            upload.responseJSON { request, response, error in
                print(response)
                callback(true)
            }
        case .Failure(_):
            callback(false)
        }
    })
}

我现在想编辑上面的代码，以便我可以在初始上传时设置一些 snippet 数据，特别是 title 和 description.

我尝试使用另一种 Alamofire 方法，它与上面的方法非常相似，只是它还需要一个 NSMutableURLRequest 作为参数。我制作了我的代码片段字典并将其设置为可变请求的 HTTPBody 属性。视频上传仍然有效，但我的片段的标题和描述值仍未设置。

如何在上传视频到 youtube 时设置一些片段信息？

Answer 1

为参数值添加一行到 multipartFormData block ，如下所示(将代码放在视频项之前):

multipartFormData.appendBodyPart(data:"{'snippet':{'title' : 'TITLE_TEXT', 'description': 'DESCRIPTION_TEXT'}}".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"snippet", mimeType: "application/json")

post url也应该改成part=snippet

https://www.googleapis.com/upload/youtube/v3/videos?part=snippet

即

.POST,
    "https://www.googleapis.com/upload/youtube/v3/videos?part=snippet",
    headers: headers,
    multipartFormData: { multipartFormData in
        multipartFormData.appendBodyPart(data:"{'snippet':{'title' : 'TITLE_TEXT', 'description': 'DESCRIPTION_TEXT'}}".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"snippet", mimeType: "application/json")
        multipartFormData.appendBodyPart(data: videodata, name: "video", fileName: "video.mp4", mimeType: "application/octet-stream")
},
