android上传图片、视频、文件，服务端使用wcf接收

最近一直在搞android上传图片、视频、文件，服务端使用wcf接收，本文对调试中的遇到的问题进行记录。

首先android上传一些小图片是比较容易的一天下来差不多就能调试出来，但是上传一些大的文件时就出现各种问题，包括wcf默认支持64k的文件，后来大图片可以上传了，但是传视频又有问题，上传的视频打不开，经过努力google最后问题终于解决了。作者kwstu QQ806693619

一、Android:

Wcf代码：

接口

1 2 3 [OperationContract] [WebInvoke(BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] string update_pictrue(Stream getStream);

实现

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 public string update_pictrue(Stream getStream) { Console.WriteLine( "setData service has bean started!" ); string uploadFolder = @"C:\kkk\"; string savaPath = "sss" ; //string dateString = DateTime.Now.ToShortDateString() + @"\"; string fileName = "ddd.mp4" ; //Stream sourceStream = request.FileData; FileStream targetStream = null ; if (!getStream.CanRead) { throw new Exception( "数据流不可读!" ); } if (savaPath == null ) savaPath = @"Photo\"; if (!savaPath.EndsWith( "\\" )) savaPath += "\\" ; uploadFolder = uploadFolder + savaPath; //+ dateString; if (!Directory.Exists(uploadFolder)) { Directory.CreateDirectory(uploadFolder); } string filePath = Path.Combine(uploadFolder, fileName); using (targetStream = new FileStream(filePath, FileMode.Create, FileAccess.Write, FileShare.None)) { //read from the input stream in 4K chunks //and save to output stream const int bufferLen = 4096 ; byte [] buffer = new byte [bufferLen]; int count = 0 ; while ((count = getStream.Read(buffer, 0 , bufferLen)) > 0 ) { targetStream.Write(buffer, 0 , count); } targetStream.Close(); getStream.Close(); } return "" ; }

配置很重要必须支持大文件上传
