我在服务器上推送视频时遇到问题。我的API在正文中有两个参数:详细信息和文件,我必须通过标题中的标记对其进行授权。
在开始时,我的文件已准备好并导出到我推送到方法的URL。接下来是详细信息(字符串值)我正在尝试准备它在服务器上发送。
运行我的应用后,我遇到了这个错误:
错误域= NSCocoaErrorDomain代码= 3840"没有值。" UserInfo = {NSDebugDescription =无值。}
响应中的服务器返回有关JSON中推送视频的所有数据
我使用本教程尝试迈出第一步: https://mindfiremobile.wordpress.com/2014/01/27/upload-video-to-server-using-multiparts/
这是我在服务器上推送视频的第一步,我很乐意提供帮助。
func postDetailsWithVideo(details: String, file: NSURL) {
let url = serverURL.URLByAppendingPathComponent("api/details")
let videoData = NSData.init(contentsOfURL: file)
let kBoundary = "---------------------------14737809831466499882746641449"
let kStartTag = "--%@\r\n"
let kEndTag = "\r\n"
let kContent = "Content-Disposition: form-data; name=\"%@\"\r\n\r\n"
let body = NSMutableData()
//details data
body.appendData(String(format: kStartTag, kBoundary).dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(String(format: kContent, "storyDetails").dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(details.dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(String(format: kEndTag).dataUsingEncoding(NSUTF8StringEncoding)!)
//Video data
body.appendData(String(format: kStartTag, kBoundary).dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("Content-Disposition: form-data; file=\"flv\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData("Content-Type: application/octet-stream\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(NSData(data: videoData!))
body.appendData(String(format: kEndTag).dataUsingEncoding(NSUTF8StringEncoding)!)
// close form
body.appendData("--\(kBoundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
let contentType = "multipart/form-data; boundary=\(kBoundary)"
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "POST"
request.setValue("Bearer \(DataManager().getAccessToken())", forHTTPHeaderField: "Authorization")
request.setValue(contentType, forHTTPHeaderField: "Content-Type")
request.HTTPBody = body
print(body)
postDataOnTheServer(request, apiMethod: "api/details")
}
func postDataOnTheServer(request: NSMutableURLRequest, apiMethod: NSString) {
let currentRequest = request
let task = NSURLSession.sharedSession().dataTaskWithRequest(currentRequest){ data, response, error in
if error != nil{
self.delegate?.errorOccured(apiMethod, error: error!)
return
}
do {
let result = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? [String:AnyObject]
self.delegate?.serverResponseFromAPIMethod(apiMethod, result: result!)
} catch {
print("response - some error")
print(error) //do something with me
}
}
task.resume()
}

它是一个服务器问题。请你的后端不要回应任何东西,你会收到回应。
