如何解决本地向服务器上传文件

长腿爸爸 2009-12-15 05:52:52

需求：
实现本地文件上传至服务器，使用的Http协议。
找了几个方法都是：
未处理 WebException
远程服务器返回错误: (405) 不允许的方法。

使用的示例代码：



  /**/

        /// <summary>

        /// WebClient上传文件至服务器

        /// </summary>

        /// <param name="fileNamePath">文件名，全路径格式</param>

        /// <param name="uriString">服务器文件夹路径</param>

        /// <param name="IsAutoRename">是否自动按照时间重命名</param>

        public void UpLoadFile(string fileNamePath, string uriString, bool IsAutoRename)

        {

            int indexOf = 0;

            if (fileNamePath.Contains("\\"))

            {

                indexOf = fileNamePath.LastIndexOf("\\");

            }

            else if (fileNamePath.Contains("/"))

            {

                indexOf = fileNamePath.LastIndexOf("/");

            }

            string fileName = fileNamePath.Substring(indexOf + 1);



            string NewFileName = fileName;

            if (IsAutoRename)

            {

                NewFileName = DateTime.Now.ToString("yyMMddhhmmss") + DateTime.Now.Millisecond.ToString() + fileNamePath.Substring(fileNamePath.LastIndexOf("."));

            }



            string fileNameExt = fileName.Substring(fileName.LastIndexOf(".") + 1);

            if (uriString.EndsWith("/") == false) uriString = uriString + "/";



            uriString = uriString + NewFileName;

 //Utility.LogWriter log = new Utility.LogWriter();

            //log.AddLog(uriString, "Log");

            //log.AddLog(fileNamePath, "Log");

            /**/

            /**/

            /**/

            /// 创建WebClient实例

            WebClient myWebClient = new WebClient();

            myWebClient.Credentials = CredentialCache.DefaultCredentials;

            // 要上传的文件

            FileStream fs = new FileStream(fileNamePath, FileMode.Open, FileAccess.Read);

            //FileStream fs = OpenFile();

            BinaryReader r = new BinaryReader(fs);

            byte[] postArray = r.ReadBytes((int)fs.Length);

            Stream postStream = myWebClient.OpenWrite(uriString, "PUT");





            try

            {



                //使用UploadFile方法可以用下面的格式

                //myWebClient.UploadFile(uriString,"PUT",fileNamePath);





                if (postStream.CanWrite)

                {

                    postStream.Write(postArray, 0, postArray.Length);

                    postStream.Close();

                    fs.Dispose();

//                    log.AddLog("上传日志文件成功！", "Log");

                }

                else

                {

                    postStream.Close();

                    fs.Dispose();

//                    log.AddLog("上传日志文件失败，文件不可写！", "Log");

                }



            }

            catch (Exception err)

            {

                postStream.Close();

                fs.Dispose();

                //Utility.LogWriter log = new Utility.LogWriter();

//                log.AddLog(err, "上传日志文件异常！", "Log");

                throw err;

            }

            finally

            {

                postStream.Close();

                fs.Dispose();

            }

        }
