httpwebresponse

问题 As the title of the topic may suggest, I have a PHP script setup on my server that, when called upon, is spitting data back to the user by echoing it back onto the page. I am then using HttpWebRequest to read the data that was put onto the page by the PHP script. While this data is encrypted, I would like for it to not appear on the page at all. I figured there must be a better way to go about doing this. If I have been unclear thus far regarding my intentions, I am looking for some way to

问题 I have run to a problem with Proxying http stream. First: I am creating http protocol media streaming server with VLC player.

But still there is one

问题 I am developing an application using twitter api and that involves writing a method to check if a user exists. Here is my code: public static bool checkUserExists(string user) { //string URL = "https://twitter.com/" + user.Trim(); //string URL = "http://api.twitter.com/1/users/show.xml?screen_name=" + user.Trim(); //string URL = "http://google.com/#hl=en&sclient=psy-ab&q=" + user.Trim(); string URL = "http://api.twitter.com/1/users/show.json?screen_name=" + user.Trim(); HttpWebRequest

问题 Suppose I am retrieving a url as follows: string url = "http://www.somesite.com/somepage.html" HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); Is there a way I can see the IP address of the destination url? Does it require a separate call? Thanks 回答1: Look at the System.Net.Dns class. You can get a list of IP addresses of the host from the Dns.GetHostEntry() method. 回答2: Although Dns.GetHostEntry() can get you the IP of

问题 I have tried to connect to a server with HttpWebRequest & HttpWebResponse and it works fine, but I got another problem I want to know when the server have been time out or disconnected, suppose something happened to my connection and I got disconnected I want to know how can I understand this in the following code: string uri = @"myUrl"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); request.Credentials = new NetworkCredential(User, Pass); ServicePointManager

问题 There are numerous posts on how to check if a URL is valid. All of them feature basically the same code, which seems to work for everyone - not for me though and I don't get why. public static bool ifURLexists(string url) { try { var request = WebRequest.Create(url) as HttpWebRequest; request.Method = "HEAD"; //response ALWAYS throws an exception using (var response = (HttpWebResponse)request.GetResponse()) { return response.StatusCode == HttpStatusCode.OK; } } catch { return false; } } I

问题 I'm trying to use HttpwebRequest and Httpwebresponse to log into a website via POST then once authenticated have it redirect to a default page within the new site. I'm able to do a responsereader.ReadttoEnd() put am unsure of how to get an automatic redirect. Dim ccContainer As New CookieContainer() Dim encoding As New ASCIIEncoding() Dim strId As String = "username" Dim strName As String = "password" Dim postData As String = "UAPMURL=&UAPMURLxx=xx&login=" & strId postData += ("&password1=" &

问题 I am currently using this script to get HTTP response headers. public static List<string> GetHttpResponseHeaders(string url) { List<string> headers = new List<string>(); WebRequest webRequest = HttpWebRequest.Create(url); using (WebResponse webResponse = webRequest.GetResponse()) { headers.Add("Status Code: " + (int) ((HttpWebResponse) webResponse).StatusCode); } return headers; } Specifically, Status Code: is what I am interested in. With that said, it appears that StatusCode() doesn't

问题 I'm trying to figure out how many times my web request was redirected before I finally landed at the end content. I'm creating my web request as follows: var httpRequest = (HttpWebRequest) WebRequest.Create("some arb path"); httpRequest.AllowAutoRedirect = followRedirects; I've had a look at the following URL http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.maximumautomaticredirections.aspx However, I do not want to impose the limit.

问题 I am building a library that allows a user to download files from a URL. One of the options I am considering is letting the user specify the expected MD5 checksum for the file; the library's GetFile(string url) function ensures that the checksum for the downloaded stream matches the one specified by the user. Being aware that the NetworkStream returned by HttpWebResponse.GetResponseStream() is not seekable, I found a way to duplicate the Stream thanks to the answers to this question: How can
