I've been having an issue with downloading webpages automatically with WebClient. Here are the steps my code runs through:
Retrieve HTML as string
Iterate through string, retrieving valid content urls (.js, .css, .png, etc.)
Download the content
Replace urls in HTML string with the content's local file path.
Save new HTML string to "main.html".
Everything is downloaded just fine. When I try to open up the html file in Chrome, it's a blank loading screen (varies from 10 seconds to 30 seconds). When the page finally loads, it looks like basic text and broken content.
The errors in the Chrome's Developer Tools suggest a lot of the .js and .css files aren't there, even though I've verified most of them are in the specified directory.
I have tried multiple sites, each with the same result.
Here is the code to retrieve the html data:
public string ScanPage(string url)
{
Console.WriteLine("Scanning url [" + url + "].");
WebClient client = new WebClient();
client.Headers.Add("user-agent", userAgent);
client.Headers.Add(HttpRequestHeader.ContentType, "text/html");
string page = string.Empty;
try
{
page = client.DownloadString(url);
Console.WriteLine("Webpage has been scanned.");
}
catch (Exception e)
{
Console.WriteLine("Error scanning page: " + e.Message);
}
client.Dispose();
return page;
}
Begin downloading data. This method is called first.
public void DownloadPageContent(string url, string contentDirectory, params string[] customExtensions)
{
//PathSafeURL(url) takes the url and removes unsafe characters
contentDirectory += PathSafeURL(url);
if (Directory.Exists(contentDirectory))
Directory.Delete(contentDirectory, true);
if (!Directory.Exists(contentDirectory))
Directory.CreateDirectory(contentDirectory);
Uri uri = new Uri(url);
string host = uri.Host;
//PageResponse is used to check for valid URLs. Irrelevant to the issue.
PageResponse urlResponse = CheckHttpPageResponse(url);
if (urlResponse.IsSuccessful())
{
//Get the html page as a string.
string data = ScanPage(url);
if (!string.IsNullOrEmpty(data))
{
//Download files with ".js" extension.
DownloadByExtension(ref data, ".js", contentDirectory + "/", "scripts/", host);
//Same as above, but with .css files.
DownloadByExtension(ref data, ".css", contentDirectory + "/", "css/", host);
//Iterate through custom extensions (.png, .jpg, .webm, etc.)
for (int i = 0; i < customExtensions.Length; i++)

HTMLContent class:

this.DownloadLink = DownloadLink;
this.Extension = Extension;

As a file downloader, this works good. For HTML downloading, it's good too. But as a complete offline webpage downloader, it does not.
EDIT:
Not sure if it matter, but I forgot to show what the userAgent variable looks like:
private const string userAgent = "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.33 Safari/537.36";

I am trying to send a file to a VM on a ESXi Server from an outside Client.
I am using the VMware SDK VMWare.Vim.dll.
When i try to use the URL given by the FileTransfer Request it Fails.
Code:
public static string ServerIP
{
get { return ConfigurationManager.AppSettings["ServerIP"].ToString(); }
}
private string ServiceUrl = "https://" + ServerIP + "/sdk";
private string UserName = "ESXIUser";
ServiceContent sc = new ServiceContent();
VimClient client = new VimClientImpl();
public VmOps()
{
}
public void Connect(string password)
{
// connect to vSphere web service
sc = client.Connect(ServiceUrl);
// Login using username/password credentials
client.Login(UserName, password);
}
public void copyDatastoreFile(/*string VMName, string Folder, string sourceFilePath*/)
{
string hostpass = "ESXIUserPAssword";
string VMName = "VMname";
string Folder = "Test";
string FileName = "test.zip";
//File destination info
string BasePath = "D:";
String targetDir = BasePath + "/" + Folder;
string srcPath = BasePath + "/" + Folder + "/" + FileName;
//Connect to the ESXi
Connect(hostpass);
NameValueCollection nvcFilter = new NameValueCollection();
nvcFilter.Add("Name", VMName);
var vm = (VirtualMachine)client.FindEntityView(typeof(VirtualMachine), null, nvcFilter, null);
GuestOperationsManager gom = new GuestOperationsManager(client, sc.GuestOperationsManager);
gom.UpdateViewData();
if (gom.FileManager == null)
{
return;
}
GuestFileManager gfm = new GuestFileManager(client, gom.FileManager);
var Auth = new NamePasswordAuthentication { Password = "VMPassword", Username = "VMUSER", InteractiveSession = false };
bool exists = false;
GuestListFileInfo fInfo = gfm.ListFilesInGuest(vm.MoRef, Auth, BasePath, null,null, Folder);
exists = fInfo.Files != null;
if (!exists)
{
// Create directory where the files will be copied to
gfm.MakeDirectoryInGuest(vm.MoRef, Auth, targetDir, true);
}
// Copy Virtual Machine file To
string URL = gfm.InitiateFileTransferToGuest(vm.MoRef,
Auth,
targetDir + "/" + FileName,
new GuestFileAttributes(),
new FileInfo(srcPath).Length,
true);
UploadFile(srcPath, URL.Replace("*", ServerIP));
}
private void UploadFile(string from, string to)
{
using (WebClient wc = new WebClient())
{
string cookie = ((VimApi_60.VimService)client.VimService).CookieContainer.GetCookies(new Uri(((VimApi_60.VimService)client.VimService).Url))[0].ToString();
wc.Credentials = new NetworkCredential("ESXiUSER", "ESXIUserPAssword");
wc.Headers.Add(HttpRequestHeader.Cookie, cookie);
try
{
wc.UploadFile(to, "PUT", from);
}
catch (WebException wex)
{
if (wex.Response != null)
{
string pageContent = new StreamReader(wex.Response.GetResponseStream()).ReadToEnd().ToString();
}
}
wc.Dispose();
}
}
URL Looks like:
"https://199.199.0.1:443/guestFile?id=22&token=23e2deef-7979-b1a8-75e5-413440d8c1377"
Cookie Looks like:
"vmware_soap_session="5e24eaa312s1245de2gg213456m23b4bd87c8e1ca"
WebException:
The remote Server returned an error:(500) Internal Server Error
ResponseStream:
\n 22\n The file Name is not valid
Anyone any experience on file Transfers with VMware SDK? Thank you for your help!
btw. it was a simple mistake, all slashs have to be switched with a double backslash. The VMWare sdk can handle the slash, but the webclient put can't.
example:
string targetDir = BasePath + "\\" + Folder;
string srcPath = BasePath + *"\\" + Folder + "\\" + FileName;
I am writing on my pdf-word converter and I just received a really strange exception witch makes no sens to me.

Its the first time that such a exception appears. but I have to be honest that I never tried to convert more then 3-4 files from pdf to word and right now I am doing more then 100 files.

Is it any possible way to create a video thumbnail from random url?
I have some links with video and I want to make a thumbnail from that video and save the thumbnail image on local storage. If any possible way to do this ?
Here is the solution for youtube videos:-
public string GetThumbnailsUrl(string url)// this url is your youtube video url
{
string imgurl = "";
if (url != "")
{
if (!url.ToLower().Contains("embed/"))//if not an embed URL
{
string v = url;
if (url.Contains("?"))
{
v = v.Substring(v.LastIndexOf("v=") + 2);
if (v.Contains("&"))
v = v.Substring(0, v.LastIndexOf("&"));
}
else
{
v = v.Substring(v.LastIndexOf("v/") + 2);
}
int i = 0;
try
{
i = Convert.ToInt32(ConfigurationManager.AppSettings["ImageSize"].Trim());//ImageSize contains the size of image.... the value is like 0,1,2,3.....
}
catch { i = 0; }
imgurl = "http://img.youtube.com/vi/" + v + "/" + i + ".jpg";
}
else//For embed URL
{
string[] sep = new string[1] { "embed/" };
string[] ss = url.Split(sep, StringSplitOptions.None);
string key = ss[ss.Length - 1];
int i = 0;
try
{
i = Convert.ToInt32(ConfigurationManager.AppSettings["ImageSize"].Trim());
}
catch { i = 0; }
imgurl = "http://img.youtube.com/vi/" + key + "/" + i + ".jpg";
}
}
return imgurl;
}
I have some code that uses the WEBDAV 'SEARCH' method to retrieve emails from an an Exchange Mailboxs 'Inbox' folder - my code takes the the innerXML of the HTTPWebRquests WEBresponse.
Using 'selectingSingleNode' on these namsspaces:
'urn:schemas:httpmail' & urn:schemas:mailheader
Alows me to extract the elements:
f:textdescription
d:fromd:subject
f:datareceived...and so on
I then create a collection of these details in a list and using the 'Subject' along with the URI use the 'PUT' method to recreate these messages in the 'draft's folder before using the 'MOVE' to send the mails (puts them in the sent items using '/##DavMailSubmissionURI##/"' statement.
The problem i have is the nature of the emails i am dealing with tend to come in with the same subject line so it gets confused with which emails have been sent/or not.
Does anyone know of a way around this, I dont know why the 'PUT' relies on the Subject line for the URI to the mail resource rather than say the HREF tag which is unique. Any ideas:
Code is below:

Using just the subject to identify email is, indeed, not a good way. If I remember it's correct, there are no automatic / obvious email id for exchange / webdav?
If you parse the subject to pick message, I would also pick more information of the email envelope - Like it size, length to create my own id. The best step should be that you create some sort of hash (check Cryptography) out of the whole message body OR i.e. first character of first xx word in the email body (heavier processing though). That will end up in same hash value everytime you call it on same email envelope. Of until the email content is leaved unchanged.
Looks like you're working with Exchange 2003. Be aware that WebDAV is no longer supported in Exchange Version 2010... and with 2007 and newer you can use a WSDL to do everything you need. All you need is an Exchange 2007 CAS to do this.
What I mentioned is a better longer term approach and has less headaches than parsing unsupported WEBDAV XML
To answer your question, there is a property that is unique per message. Use MFCMapi (on codeplex) to look for it. The property will be named "MessageURL" or something like that. Use that property in the URL for your webdav calls.
I am trying to make a web server in C#, i need to get the requested url and then list the files and folders requested.This is good to get the first directory .
For Eg. My webserver root is c:\test when i open localhost i get the contents of test folder. Say Data is subfolder of c:\test, i can click on data from the browser and get into C:\test\data now when i click on any folder then the get request comes with %2F instead of c:\test\data\ok and so i am stuck.
Code to Recieve The Request :
sRequest = sBuffer.Substring(0, iStartPos - 1);
sRequest.Replace("\\", "/");
if ((sRequest.IndexOf(".") < 1) && (!sRequest.EndsWith("/")))
{
sRequest = sRequest + "/";
}
iStartPos = sRequest.LastIndexOf("/") + 1;
sRequestedFile = sRequest.Substring(iStartPos);
sDirName = sRequest.Substring(sRequest.IndexOf("/"), sRequest.LastIndexOf("/") - 3);
if (sDirName == "/")
sLocalDir = sMyWebServerRoot;
else
{
//Get the Virtual Directory
// sLocalDir = GetLocalPath(sMyWebServerRoot, sDirName);
Console.WriteLine("i am here");
sDirName = sDirName.Substring(1, sDirName.Length - 2);
//sDirName = sDirName.Replace("/", "\\");
Console.WriteLine("Amit:" + sDirName);
string test1 = Path.Combine("C:\\test\\", sDirName);
sLocalDir = Path.Combine(#"C:\\test", sDirName);
}
Now to List Dir I have the following Function :
public String listdir(string sLocaldir,string sDirName)
{
string sresult = "";
StringBuilder sb = new StringBuilder();
sb.AppendLine("<html>");
sb.AppendLine("<head>");
sb.AppendLine("<title>Test</title>");
sb.AppendLine("</head>");
sb.AppendLine("<body>");
sb.AppendLine("<h1><center><u>Listing Folders Under " + sLocaldir + "</h1></u></center>");
string[] folderpaths = Directory.GetDirectories(sLocaldir);
sb.AppendLine("<font color=red><font size=5>Listing Directories<br>");
for (int i = 0; i < folderpaths.Length; i++)
{
string fpath = folderpaths[i];
string[] foldernames = fpath.Split('\\');
int j = foldernames.Length - 1;
string fname = foldernames[j];
string fullname;
if (sDirName != "/")
{
//fname= fname + "\\";
fullname = sDirName +"/"+ fname;
//fullname = fullname.Replace("\\", "/");
//fullname = Path.GetPathRoot("C:\\test");
Console.WriteLine("Get full path:" + fullname);
}
else
{
fullname = fname;
}
Console.WriteLine("Full Test:" + fullname);
//sb.AppendLine(string.Format("<img src=file.png height=20 width=20>{1}<br>",
sb.AppendLine(string.Format("<img src=file.png height=20 width=20>{1}<br>",
HttpUtility.HtmlEncode(HttpUtility.UrlEncode(fullname )),
HttpUtility.HtmlEncode(fname)));
}
string[] filePaths = Directory.GetFiles(#"C:\test");
sb.AppendLine("<font color=red><font size=5>Listing Files<br>");
for (int i = 0; i < filePaths.Length; ++i)
{
string name = Path.GetFileName(filePaths[i]);
sb.AppendLine(string.Format("<img src=file.png height=20 width=20>{1}<br>",
HttpUtility.HtmlEncode(HttpUtility.UrlEncode(name)),
HttpUtility.HtmlEncode(name)));
}
sb.AppendLine("</ul>");
sb.AppendLine("</body>");
sb.AppendLine("</html>");
sresult = sb.ToString();
return sresult;
//Console.WriteLine(sresult);
}
Any help would be highly appreciated.
