ios - 上传视频文件到服务器

Question

我已将视频文件上传到服务器，但文件大小为零。

let url:NSURL? = NSURL(string: (Config.sampleuploadurl as String)+"/uploadServlet?chehara_email=\(candit_email)")
// let url:NSURL? = NSURL(string: (Config.apiUrl as String)+"/UploadServlet?chehara_email=\(candit_email)")
print(url)
let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData
var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 2.0)
request.HTTPMethod = "POST"
let boundaryConstant = "Boundary-7MA4YWxkTLLu0UIW"; // This should be auto-generated.
let contentType = "multipart/form-data; boundary=" + boundaryConstant

let fileName:String = videoName

let mimeType = "text/MOV"
let fieldName = "uploadFile"

request.setValue(contentType, forHTTPHeaderField: "Content-Type")

var error: NSError?
var dataString = "--\(boundaryConstant)\r\n"

dataString += "Content-Disposition: form-data; name=\"\(fieldName)\"; filename=\"\(fileName)\"\r\n"
print("dataString")

dataString += "Content-Type: \(mimeType)\r\n\r\n"
print(dataString)

dataString += String(contentsOfFile: videoName, encoding: NSUTF8StringEncoding, error: &error)!   // This is Error Line

dataString += "\r\n"
dataString += "--\(boundaryConstant)--\r\n"

let requestBodyData = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
print("Request")
print(requestBodyData)

request.HTTPBody = requestBodyData
print(request.HTTPBody)

})

埃里克， 你不应该使用 NSMutableURLRequest，你应该使用 NSURLSession。这是我在其他地方发布的一些代码

http://stackoverflow.com/questions/35604866/swift-send-file-to-server/35609325#35609325

我回复的这篇文章也显示了它的实现。 NSMutableURLRequest 正在被贬值。

这是关于该主题的几个优秀教程之一；不，我不是伪装的巴特·雅各布斯:)
