问题 I am currently working on an implementation of an application for Windows Phone 7 that should retrieve the SHOUTcast stream (inspired by this question). The stream location is represented by an IP address and a port. Here is an example of a SHOUTcast stream URL: http://78.159.104.183:80 I am trying to make a HttpWebRequest to get the data from the stream: HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://78.159.104.183:80") ; Once the request is initialized, I am trying to

How to create a request to a URL and write the response to the page

问题 I believe I've done this before, but I can't seem to remember how:( HttpWebRequest request = (HttpWebRequest)WebRequest.Create("www.example.com"); request.Method = "GET"; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); How do I then write the response to the page? Thanks a lot. 回答1: The below example demonstrates how it can be done: string myRequest = "abc=1&pqr=2&lmn=3"; string myResponse=""; string myUrl = "Where you want to post data"; System.IO.StreamWriter myWriter =

I'm getting a string in a json format from the Rotten Tomatoes website. My code looks like HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.Create(url); webRequest.Method = "GET"; webRequest.ContentType = "application/json"; HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse(); using(StreamReader reader = new StreamReader(response.GetResponseStream())) { //Code I'm using the reader with } When I run a movie search that returns 1 - 4 movies it works fine. However, If I try to get the results of 5 or more it won't work. The webResponse contentlength is -1. When I'm

VB.NET Use WebRequest to check if URI is valid

问题 Looking for the best way to determine if a URI exists in VB.NET without downloading the actual content. System.IO.FileExists / My.Computer.FileSystem.FileExists can be used locally to determine if a file exists, is there an equivalent for the Web? Currently I am using a HttpWebRequest to check URI existance using the ResponseStream . This populates the stream if the target does exist and throws an exception if it doesn't. The function is being expanded to also check for PDF files (typically

How to manitain session values during HttpWebRequest?

In my code I'm sending a HttpWebRequest to a page in my website. When request sends to this page, It doesn't maintain the Session values. Below is the code, from where I'm generating the web request: Public Overloads Shared Function ReadURL(ByVal sUrl As String) As String Dim sBody As String Dim oResponse As HttpWebResponse Dim oRequest As HttpWebRequest Dim oCookies As New CookieContainer oRequest = WebRequest.Create("http://localhost:64802/inventory/purchase_order.aspx?id=5654") oRequest.CookieContainer = oCookies oResponse = oRequest.GetResponse() Dim oReader As New StreamReader(oResponse

How do I get the local port number of an HttpWebRequest?

I'm making a long-running request with an HttpWebRequest asynchronously. While the request is running, I'd like to be able to get the local port of the request (ie, the one on the client, not the server). How do I do that? I've looked at HttpWebRequest.ServicePoint.BindIPEndPointDelegate, but that just seems to allow the caller to specify the local addy/port. Ideally, I'd like to allow HttpWebRequest to pick its local port normally and then ask it what it chose. Unfortunately, the HttpWebRequest class really does not expose what you are asking for. I don't recommend what I'll say below to be

I am trying to post a Json to our web service. My problem is that when my request.ContentLength exceeds 7kb. I will get a web exception 500 at request.GetResponse(). But if my request.ContentLength is below 7kb, my post is successfully sent. Error Message: The remote server returned an error: (500) Internal Server Error. Source code: public static string JsonPost(string url, string method, string postData) { Uri address = new Uri(url + method); HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest; request.Method = "POST"; request.ContentType = "application/json"; byte[]

How to read the response stream before the Http response completes

跟風遠走 提交于 2019-12-05 08:22:20
When making a request using HttpWebRequest object, I need to call the method GetResponse() to send the request and get the response back. The problem with this method is that it doesn't return the response object until all data has been received. Say I am downloading a 100 MB file, I won't be able to read it until the response finish and all the 100 MB is downloaded. What I want is to be able to read the response stream bytes as soon as they arrive, without waiting for the response to complete. I know I can use the Range Http header, but it won't work on my situation. scherand I think this is
