wcf rest 服務用於安卓和ISO調用2-------檔案上傳

標籤：

接著上次寫.......................

這次利用wcf rest 上傳檔案.廢話不多說.接著寫代碼.

在上次的介面中添加上傳檔案方法UpLoad,代碼如下:

[WebInvoke(Method = "POST", UriTemplate = "UpLoad/{fileName}",        ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]        [System.ComponentModel.Description("上傳檔案")]        bool UpLoad(System.IO.Stream stream, string fileName);

然後編寫介面的方法實現:

 public bool UpLoad(Stream stream, string fileName)        {            try            {                byte[] buffer = new byte[1024];                FileStream fs = new FileStream(@"d:\test\" + fileName, FileMode.Create, FileAccess.Write);                int count = 0;                while ((count = stream.Read(buffer, 0, buffer.Length)) > 0)                {                    fs.Write(buffer, 0, count);                }                //清空緩衝區                fs.Flush();                //關閉流                fs.Close();                return true;            }            catch (Exception ex)            {                LogHelper.Error("儲存檔案失敗", ex);                return false;            }        }

　　這裡儲存的路徑,我就固定到d:\test檔案夾下面.然後在瀏覽器裡面查看一下.

　　接下來就編寫用戶端代碼進行調用.接著上次的控制台應用程式寫.代碼如

 public static  void UploadFile()        {            Console.WriteLine("--------------上傳檔案----------------");            HttpClient httpClient = new HttpClient();            string uri = "http://localhost:31572/Service1.svc/UpLoad/";            try            {                string str;                do                {                    Stopwatch stopwatch = new Stopwatch();                    Console.WriteLine("請輸入上傳檔案路徑:");                    string filePath = Console.ReadLine();                    if (!string.IsNullOrEmpty(filePath) && File.Exists(filePath))                    {                        string fileName = filePath.Substring(filePath.LastIndexOf("\\", StringComparison.Ordinal)+1);                        Console.WriteLine("開始上傳檔案...");                        Stream fs = new FileStream(filePath, FileMode.Open);                        HttpContent content = new StreamContent(fs);                        stopwatch.Start();                        var response =  httpClient.PostAsync(uri + fileName, content);                        response.Result.EnsureSuccessStatusCode();                        Console.WriteLine("檔案:{0},上傳結果:{1}", fileName, response.Result.Content.ReadAsStringAsync().Result);                        Console.WriteLine("上傳檔案所需時間:{0}", stopwatch.ElapsedMilliseconds);                    }                    else                    {                        Console.WriteLine("請輸入正確的檔案路徑");                    }                    Console.WriteLine("y/n是否繼續上傳?");                   str = Console.ReadLine();                } while (str=="y");            }            catch (Exception ex)            {                Console.WriteLine(ex);                Console.Read();            }        }

　　最後效果如:

下一篇就是soap和rest如何一起使用.
