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();

}
try

}
}
catch (Exception ex)
{

throw;
}
}

2016 / 10 / 30 搬機房, 有幾件事沒有做好, 記錄一下:
1. Firewall 沒設定好, 下次要一中兩個人一起設定.
2. 有一個客戶的 DNS 等了一整天才生效, 要檢查所有網站的 TTL 和 Refresh 時間, 最好都在一個小時以內.
3. Email 主機: 有些客戶原來是用 msa.hinet.net 這個 SMTP, 搬到非 Hinet 的機房後就不能寄信了.
4. 某一個客戶的 DNS 沒改好, 因為在自已的 DNS Server 上面看到有記錄, 就誤判是我們代管的, 應該要用 Hinet 或 Google 來確認 NS Record 為何. 已刪除它的 DNS 記錄.
5. 202 的 .8 網路線沒插好, 主機開起來後, 要確認可以從每一個介面 Ping 出去.
6. 新 Firewall , 內部 IP 無法連到 Virtual Server: --> 要由內部 IP 連線到 Virtual Server 測試. 最好是在 hosts 上面都有 127.0.0.1 的設定.
7. 最好不要在下半年換機房, 比較忙, 客戶的活動也比較多.
8. Windows 的 DNS 若是直接修改 DNS 檔案. 因為 SOA 的序號沒有修改, 所以 Client 伺服器要手動重新讀取資料.
9. 要記得改 TWNIC 的 DNS Server設定.
