頁數 2 / 5 上一頁 下一頁
搜尋 url 結果:
zero-width space
寫程式這麼多年,終於被這個東西給害到,所以特別提一下
zero-width space: 就是沒有寬度的空白,字元碼  \u200b , 或是 urlencode =  %e2%80%8b
當你從 word , excel ,PDF 複製文字貼到記事本,網頁textbox, 或是 visual studio
有時候會把這個碼也一起貼上,重點是: 你肉眼根本看不出來

​2017-08-15 22:05:15​ -> 2017前面有 \u200b, 尾巴也有 
2017-08-15 22:05:15 -> 這個就正常

這會造成甚麼,DateTime.Parse 就會出錯,或是對字串做 MD5 hash 會造成錯誤的結果
然後就會一直 debug 找不出原因,要用 urlencode 測看看才會現出原形
另外,這個碼也無法用 Trim() 清掉,因為他不是 Char.IsWhiteSpace 成員

所以,從 word excel pdf 或是其他網頁 copy 文字貼到程式碼做測試
如果發生怪怪的bug,可能要思考一下是不是這個字元在作怪

LINE Pay介接
LINE Pay款流程:

Post File With C#
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)

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

        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 =

簡單的 HTTP Relay By MVC.
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>

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

css 存取字型檔無法跨網站
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

自製 radio button & checkbox 的注意事項
自製input 的 radio button 和 checkbox 之前常見的做法是,在input旁邊加入:not(old)的選擇器,如下所例 (以下寫法為SCSS格式)

input[type="radio"]:not(old){
width:28px;
margin:0;
padding:0;
@include opacity(0);
}
input[type="radio"]:not(old) + label{
display: inline-block;
margin-left: -28px;
padding-left: 18px;
background: url("//www.shopunt.com/images/eng/btn/radio.png") no-repeat;
width:auto;
line-height: 12px;
}
input[type="radio"]:not(old):checked + label{
background: url("//www.shopunt.com/images/eng/btn/radio-r.png") no-repeat;
width:auto;
}


但是chrome的新版本(39版)後開始,不能直接在input旁邊加:not(old),這段語法,點擊後,會無法正常顯示,所以解決的方法有兩個
1. 要使用:not(old)這段語法,不能在input旁邊加,必須是在他的外層上加,如下所例

.r-btn:not(old){
    input[type="radio"]{
     width:28px;
     margin:0;
     padding:0;
     @include opacity(0);
    }
    input[type="radio"] + label{
     display: inline-block;
     margin-left: -28px;
     padding-left: 18px;
     background: url("//www.shopunt.com/images/eng/btn/radio.png") no-repeat;
     width:auto;
     line-height: 12px;
    }
    input[type="radio"]:checked + label{
     background: url("//www.shopunt.com/images/eng/btn/radio-r.png") no-repeat;
     width:auto;
    }
}


2. 不使用:not(old),改用:not(:checked)寫法,Selectors 4也建議使用此語法,如下所例
input[type="radio"]:not(:checked), input[type="radio"]:checked {
    position: absolute;
    left: -9999px;
}
input[type="radio"]:not(checked) + label{
display: inline-block;
margin-left: 4px;
padding-left: 18px;
background: url("//www.shopunt.com/images/eng/btn/radio.png") no-repeat;
width:auto;
line-height: 12px;
}
input[type="radio"]:checked + label{
background: url("//www.shopunt.com/images/eng/btn/radio-r.png") no-repeat;
width:auto;
}
