Post 的資料好像會變大, 要改 Web.config

<system.web>

    <httpRuntime requestValidationMode="2.0" maxRequestLength="1024000"/>

</system.web>

程式碼如下:

public string UploadFilesToRemoteUrl(string url, string[] files, NameValueCollection formFields = null)

    {

        string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");



        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

        request.ContentType = "multipart/form-data; boundary=" +

                                boundary;

        request.Method = "POST";

        request.KeepAlive = true;



        Stream memStream = new System.IO.MemoryStream();



        var boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +

                                                                boundary + "\r\n");

        var endBoundaryBytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +

                                                                    boundary + "--");





        string formdataTemplate = "\r\n--" + boundary +

                                    "\r\nContent-Disposition: form-data; name=\"{0}\";\r\n\r\n{1}";



        if (formFields != null)

        {

            foreach (string key in formFields.Keys)

            {

                string formitem = string.Format(formdataTemplate, key, formFields[key]);

                byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(formitem);

                memStream.Write(formitembytes, 0, formitembytes.Length);

            }

        }



        string headerTemplate =

            "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n" +

            "Content-Type: application/octet-stream\r\n\r\n";



        for (int i = 0; i < files.Length; i++)

        {

            memStream.Write(boundarybytes, 0, boundarybytes.Length);

            var header = string.Format(headerTemplate, "uplTheFile", files[i]);

            var headerbytes = System.Text.Encoding.UTF8.GetBytes(header);



            memStream.Write(headerbytes, 0, headerbytes.Length);



            using (var fileStream = new FileStream(files[i], FileMode.Open, FileAccess.Read))

            {

                var buffer = new byte[1024];

                var bytesRead = 0;

                while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)

                {

                    Response.Write("bytesRead: " + bytesRead.ToString() + "<br>");

                    memStream.Write(buffer, 0, bytesRead);

                }

            }

        }



        memStream.Write(endBoundaryBytes, 0, endBoundaryBytes.Length);

        request.ContentLength = memStream.Length;



        using (Stream requestStream = request.GetRequestStream())

        {

            memStream.Position = 0;

            byte[] tempBuffer = new byte[memStream.Length];

            memStream.Read(tempBuffer, 0, tempBuffer.Length);

            memStream.Close();

            requestStream.Write(tempBuffer, 0, tempBuffer.Length);

        }



        try

        {

            using (var response = request.GetResponse())

            {

                Stream stream2 = response.GetResponseStream();

                StreamReader reader2 = new StreamReader(stream2);

                return reader2.ReadToEnd();

            }

        }

        catch (Exception ex)

        {

            return (ex.ToString());

            throw;

        }

    }

客戶要求
1. 檔案只能放在 Firewall 內的後台用 Web server (Server A).
2. 使用者只能存取 DMZ 的 Web server (Server B).
3. Server B 只能用 HTTP 通過 Firewall 向 Server A 要資料.(i.e.  Server B 不能掛戴 Server A 的目錄成為虛擬目錄)

所以在 Server B 上面建立了一支程式用 HTTP 的方式讀取 Server A 的檔案再寫出去.

例如, http://ServerB/Upload/test.pdf 會讀取 http://ServerA/Upload/test.pdf 再送到 Client 端

namespace WWW.Controllers

{

    public class UploadController : Controller

    {

        // GET: Upload

        public void Index(string Filename)

        {

            //Create a stream for the file

            Stream stream = null;



            //This controls how many bytes to read at a time and send to the client

            int bytesToRead = 10000;



            // Buffer to read bytes in chunk size specified above

            byte[] buffer = new Byte[bytesToRead];



            string url = "http://admin-dev.nanya.bike.idv.tw/newnanyaback/Upload/" + Filename;



            // The number of bytes read

            try

            {

                //Create a WebRequest to get the file

                HttpWebRequest fileReq = (HttpWebRequest)HttpWebRequest.Create(url);



                //Create a response for this request

                HttpWebResponse fileResp = (HttpWebResponse)fileReq.GetResponse();



                if (fileReq.ContentLength > 0)

                    fileResp.ContentLength = fileReq.ContentLength;



                //Get the Stream returned from the response

                stream = fileResp.GetResponseStream();



                // prepare the response to the client. resp is the client Response

                var resp = HttpContext.Response;



                if (Filename.ToLower().EndsWith(".png") ||

                    Filename.ToLower().EndsWith(".jpg") ||

                    Filename.ToLower().EndsWith(".jpeg") ||

                    Filename.ToLower().EndsWith(".gif")

                    )

                {

                    resp.ContentType = "image";

                }

                else

                {

                    //Indicate the type of data being sent

                    resp.ContentType = "application/octet-stream";



                    //Name the file

                    resp.AddHeader("Content-Disposition", "attachment; filename=\"" + HttpUtility.UrlEncode(Filename, Encoding.UTF8) + "\"");

                }



                resp.AddHeader("Content-Length", fileResp.ContentLength.ToString());



                int length;

                do

                {

                    // Verify that the client is connected.

                    if (resp.IsClientConnected)

                    {

                        // Read data into the buffer.

                        length = stream.Read(buffer, 0, bytesToRead);



                        // and write it out to the response's output stream

                        resp.OutputStream.Write(buffer, 0, length);



                        // Flush the data

                        resp.Flush();



                        //Clear the buffer

                        buffer = new Byte[bytesToRead];

                    }

                    else

                    {

                        // cancel the download if client has disconnected

                        length = -1;

                    }

                } while (length > 0); //Repeat until no data is read

            }

            finally

            {

                if (stream != null)

                {

                    //Close the input stream

                    stream.Close();

                }

            }

        }

    }

}

但不是這樣就好了, 在 RouteConfig.cs 中要加上:
            routes.MapRoute(
                name: "Upload",
                url: "Upload/{filename}",
                defaults: new { controller = "Upload", action = "Index", filename = UrlParameter.Optional }
            );

此外在 Web.Config 中也要加上:

  <system.webServer>
    <handlers>
      <add name="UrlRoutingHandler_Upload"
           type="System.Web.Routing.UrlRoutingHandler, 
               System.Web, Version=4.0.0.0, 
               Culture=neutral, 
               PublicKeyToken=b03f5f7f11d50a3a"
           path="/Upload/*"
           verb="GET"/>
    </handlers>
  </system.webServer>

在 .100 安裝 MVC 專案時, web.config 要記得檢查有沒有設定 UrlRoutingModule, 如下. 否則會出現 404 的錯誤.
 

<system.webServer>
  <modules>
    <remove name="UrlRoutingModule-4.0" />
    <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
  </modules>
</system.webServer>

JavaScriptSerializer、DataContractJsonSerializer及Json.NET

比較

目前是使用 Json.NET >  工具 程式褲套建管理員  > Package manager console 

PM>  Install-Package Newtonsoft.Json

​就可以安裝了
 

錯誤訊息如下, 完全沒有錯誤訊息, 以及沒有錯誤的程式碼位置

查了一下，原來網址後面多了空白 (%20) , 也就是 ? 前面多了空白
只是exception物件會自作聰明把他濾掉了，反而從 exception log 看不到資料
測試過，userd可以正常看網站，只是server會有不斷 excetion產生，有點煩
網路上雖有一些解法，但我想還是要求下廣告時，要注意網址問題


 

當A網站的 css 去下載另一B網站的字型檔 (.ttf, .woff .. 等)
語法

@font-face { src: url('.....woff')

此時瀏覽器會使用 XHR 方存取字型檔案  因此會產生跨站問題 (CORS)
https://developer.mozilla.org/zh-TW/docs/HTTP/Access_control_CORS
所以無法下載字型檔

解決方法:
B網域網站要加上 http header，允許A網站存取
語法

Access-Control-Allow-Origin: http://foo.example

當然，http://foo.example 可以改成 * (星號)  表示所有站台都可以存取

http://blog.zhusee.in/post/48857667691/jquery-deferred-object

deferred.done(callback)  #=> 成功時執行
deferred.fail(callback)  #=> 失敗時執行
deferred.progress(callback)  #=> 還在跑，但是裡面的程式使用 `.notify` 方法通知進度
deferred.always(callback)  #=> 無論成功或失敗都會執行
deferred.when(filters)  #=> 在呼叫 callback 前先處理資料，後面解釋

當所有 Deferred 都完成後，註冊在 $.when() 下面的 callback 會拿到第一個 Deferred 物件傳給 callback 的參數

var d1 = $.Deferred(), d2 = $.Deferred(),
     w = $.when(d1, d2);

  w.done(function(msg) { console.log(msg) });

  d1.resolve("Part A done");
  d2.resolve("Part B done");

  #=> "Part A done"

因為 useragent 是可以改的 所以也是 injection  的入口

用了大概一年半的 git flow(是 git 的一種開發規範) ，最近才開始有一點領會到分散式的精神，
先簡單比較一下，在開發新功能上 集中式與分散式的差別

SVN(集中式): 
從 SVN Server Update到最新的版本 ->
開始照著需求修改程式 ->
遇到程式被鎖住請他unlock ->
繼續開發 ->
開發完成把 修改過的程式 commit 到 SVN Server 上

git(分散式): git flow
先從server 上的 repository 拉下最新的版本 到自己的 repository
(這邊很不一樣 git 會有一個主要的repository 然後開發端又有自己的) ->
建立一個新的Branch來作為開發用 ->
開發程式(不會去Server 上確認是有人在改相同的程式) ->
開發完 commit 到自己的local端的 repository ->
送一個合併 Branch 的需求 ->
管理的人做 Code Review 然後把開發的新分支合併

優缺點:
集中式從頭到尾都只有 1 個 repository，確保了所有人的程式都是同一個版本，
如果現在有兩個新的 feature 都要改同一支程式，就必須先後開發的必要，或是
日後做 merge 的動作，但集中式的設計，並不強迫我們做 code review 的動作
，所以要解決 conflict 時會額外耗時也抗拒。

或是我同時要開發兩個新功能，在集中式管理，我們勢必會包一包一起commit，
但在git flow 上就會開兩個 branch，在未來我們更容易了解整個開發歷史。

git flow 使用經驗中，獲得最多的其實是 Code Review 的過程，Code Review
大家會更能接受自己的做法被質疑，從討論中得到更簡易解法，進而改善整個專案
的品質和可維護性，同時可以降低duplicate code 的情況。 
 
更重要的了解 git 後，可以在 github 上面跟全世界的人一起開發(雖然我沒機會到共
同開發其他專案)，有更通用的 naming convention，更多解決方案工具。

慧守CKEditor編輯器版本更新(目前版本IE11無法使用)，更新至4.4.7後，大部份IE11皆正常，但有台電腦無法正常運作。
該電腦：




原套用方法：

<textarea style="width:675px; height:60px" name="Description" id="Description">#Description#</textarea>

                                            <script type="text/javascript">

                                                CKEDITOR.replace('Description');

                                            </script>

更改為下面方法即可：
​

<textarea style="width:675px; height:60px" name="Description" id="Description">#Description#</textarea>

                                            <script type="text/javascript">

                                                $('#Description').ckeditor();
