ブログは仕事の勉強で出会った穴を記録するだけで、交流を歓迎します.

1.ファイルフロー

1.1クライアント

アップロードコンポーネントからInputStreamを取得しbyte[]に変換し、オブジェクトを組み立ててアップロードする

  try{    byte[] buffer = new byte[filedata.InputStream.Length];
                filedata.InputStream.Read(buffer, 0, buffer.Length);
                var requstData = new
                {
                    file = buffer,
                    path = resultPath,
                    fileName = filename
                };
                var result = UrlRequestHelper.HttpPostRequst(ConfigurationManager.AppSettings["FileUploadPath"], JsonConvert.SerializeObject(requstData), "");
            }

httppost書き換え

 /// 

        ///   post  
        /// 
        ///         
        /// 
        public static string HttpPostRequst(string url, string postData, string ActionUrl)
        {
            byte[] bs = Encoding.UTF8.GetBytes(postData);

            HttpWebRequest result = (HttpWebRequest)WebRequest.Create(url + ActionUrl);
            result.ContentType = "application/json";
            result.ContentLength = bs.Length;
            result.Method = "POST";

            using (Stream reqStream = result.GetRequestStream())
            {
                reqStream.Write(bs, 0, bs.Length);
            }
            using (WebResponse wr = result.GetResponse())
            {
                string reader = new StreamReader(wr.GetResponseStream(),
                    Encoding.UTF8).ReadToEnd();
                return reader;
            }
        }

WebconfigのmaxRequestLengthの設定

1.2 webapi

受信最大値の設定

[FromBody]object bitで受信し、DeserializeObjectからオブジェクトを転送

  [HttpPost]
        public string FileUp([FromBody] object bit)

        {

            lock (_lock)
            {
                string jsonstr = JsonConvert.SerializeObject(bit);
                Data res = JsonConvert.DeserializeObject(jsonstr);

                return SaveFile(res.file, res.path, res.fileName);
            }
        }

ポイント:byte[]streamを転送し、ファイルに書き込む.

   private string SaveFile(byte[] file, string path, string fileName)
        {
            try
            {
                var serverPath = configPath;   //    
                CreatePath(serverPath + @path);
                var filename = fileName;
                var filePath = string.Format(@"{0}\{1}", serverPath + @path, filename);     //      
                var fullpath = filePath;     //     
               
                //      

                using (var ms = new MemoryStream())
                {
                    MemoryStream m = new MemoryStream(file);
                    string files = string.Format(@"{0}", fullpath);
                    FileStream fs = new FileStream(files, FileMode.OpenOrCreate);
                    m.WriteTo(fs);
                    m.Close();
                    fs.Close();
                    m = null;
                    fs = null;
                    return fullpath;
                }
            }
            catch (Exception ex)
            {
                throw ex;

            }
        }

発生したピット:フォルダ権限の問題(発生しなかった場合は使用できません)

 /// 

        ///       
        /// 
        /// 
        /// 
        private void CreatePath(string filepath)
        {
            if (!Directory.Exists(filepath))
            {
                var securityRules = new DirectorySecurity();
                securityRules.AddAccessRule(new FileSystemAccessRule(System.Environment.UserName, FileSystemRights.FullControl, AccessControlType.Allow));
                securityRules.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
                securityRules.AddAccessRule(new FileSystemAccessRule("NETWORK SERVICE", FileSystemRights.FullControl, AccessControlType.Allow));
                Directory.CreateDirectory(filepath, securityRules);
            }
        }
