wcf rest 服务用于安卓和ISO调用2-------文件上传

Posted 2020-06-13

接着上次写.......................

这次利用wcf rest 上传文件.废话不多说.接着写代码.

在上次的接口中添加上传文件方法UpLoad,代码如下:

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

然后编写接口的方法实现:

 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);
                }
                //清空缓冲区
                fs.Flush();
                //关闭流
                fs.Close();
                return true;
            }
            catch (Exception ex)
            {
                LogHelper.Error("保存文件失败", ex);
                return false;
            }
        }

　　这里保存的路径,我就固定到d:\test文件夹下面.然后在浏览器里面查看一下.

　　接下来就编写客户端代码进行调用.接着上次的控制台应用程序写.代码如下图

 public static  void UploadFile()
        {
            Console.WriteLine("--------------上传文件----------------");

            HttpClient httpClient = new HttpClient();
            string uri = "http://localhost:31572/Service1.svc/UpLoad/";
            try
            {
                string str;
                do
                {
                    Stopwatch stopwatch = new Stopwatch();
                    Console.WriteLine("请输入上传文件路径:");
                    string filePath = Console.ReadLine();
                    if (!string.IsNullOrEmpty(filePath) && File.Exists(filePath))
                    {
                        string fileName = filePath.Substring(filePath.LastIndexOf("\\", StringComparison.Ordinal)+1);
                        Console.WriteLine("开始上传文件...");
                        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("文件:{0},上传结果:{1}", fileName, response.Result.Content.ReadAsStringAsync().Result);
                        Console.WriteLine("上传文件所需时间:{0}", stopwatch.ElapsedMilliseconds);
                    }
                    else
                    {
                        Console.WriteLine("请输入正确的文件路径");
                    }
                    Console.WriteLine("y/n是否继续上传?");
                   str = Console.ReadLine();
                } while (str=="y");
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex);
                Console.Read();
            }
        }

　　最后效果如下图:
