swift – NSURLSessionUploadTask超时

概述我正在使用AFNetworking将视频文件上传到服务器,我几乎每次尝试上传文件时都会暂停上传. 我正在尝试同时上传多个文件,到目前为止,我尝试的最大值是2,因为它们保持超时. 相关守则： for i in 0 ... 2 { let filePath : NSURL = NSURL(fileURLWithPath: "filepathgoeshere") 我正在使用AFNetworking将视频文件上传到服务器,我几乎每次尝试上传文件时都会暂停上传.

我正在尝试同时上传多个文件,到目前为止,我尝试的最大值是2,因为它们保持超时.

相关守则：

for i in 0 ... 2 {            let filePath : NSURL = NSURL(fileURLWithPath: "filepathgoeshere")            let tempfilename = String(format: "%f",NSDate.timeIntervalSinceReferenceDate())            let tempfileUrl = NSURL(fileURLWithPath: "\(NstemporaryDirectory())\(tempfilename)")            let request = AFhttpRequestSerializer().multipartFormRequestWithMethod("POST",URLString: getAPIURL(),parameters: parameters,constructingBodyWithBlock: { (formData : AFMultipartFormData!) -> VoID in                formData.appendPartWithfileURL(filePath,name: "file",filename: "file",mimeType: "vIDeo/mp4",error: nil)                },error: nil)            // Work around for problem with multi-part requests not giving a content-length and being rejected by S3            // See: https://github.com/AFNetworking/AFNetworking/issues/1398            AFhttpRequestSerializer().requestWithMultipartFormRequest(request,writingStreamContentsTofile: tempfileUrl,completionHandler: { (error: NSError!) -> VoID in                var manager : AFURLSessionManager = AFURLSessionManager(sessionConfiguration: NSURLSessionConfiguration.defaultSessionConfiguration())                var progress : nsprogress? = nil                var uploadTask : NSURLSessionUploadTask = manager.uploadTaskWithRequest(request,fromfile: tempfileUrl,progress: &progress,completionHandler: { (response: NSURLResponse!,responSEObject: AnyObject!,error: NSError!) -> VoID in                    NSfileManager.defaultManager().removeItemAtURL(tempfileUrl,error: nil)                    if let err = error {                        println("There was an error :(")                        println("Error: \(err.localizedDescription)")                        // Todo: Add in relevant error catching                        successCallback(success: false)                    } else {                        successCallback(success: true)                    }                })                if let testNil = progress {                    progressCallback(progress: progress)                }                uploadTask.resume()            })        }

解决方法

func multiplefileUploadRequestSessionManager(url:String,parameters:NSDictionary,fileInfo:NSArray,completionHandler: (response:NSURLResponse?,responSEObject:AnyObject?,error:NSError?) -> ())    {        let request : NSMutableURLRequest = AFhttpRequestSerializer().multipartFormRequestWithMethod("POST",URLString: url,constructingBodyWithBlock: { (formData) -> VoID in            if(fileInfo.count > 0)            {                for file in fileInfo                {                    var fileData    = file.valueForKey("fileData") as NSData                    var name        = file.valueForKey("filenameData") as String                    var filename    = file.valueForKey("filename") as String                    var mimeType    = file.valueForKey("mimeType") as String                    formData.appendPartWithfileData(fileData,name: name,filename: filename,mimeType: mimeType)                }            }        },error: nil)        let conf : NSURLSessionConfiguration = NSURLSessionConfiguration.defaultSessionConfiguration()        let manager : AFURLSessionManager = AFURLSessionManager(sessionConfiguration: conf)        var progress : nsprogress? = nil        var uploadTask:NSURLSessionUploadTask = manager.uploadTaskWithStreamedRequest(request,progress: nil) { (response,responSEObject,error) -> VoID in            completionHandler(response:response,responSEObject:responSEObject,error:error)        }        uploadTask.resume()}

这可能有助于您进行多个文件上传
