android上传图片、视频、文件，服务端使用wcf接收

浏览数：28 / 时间：2015年06月11日

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

Wcf代码：

接口

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

实现

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
