httpwebresponse

问题 How to let Httpwebresponse ignore the 404 error and continue with it? It's easier than looking for exceptions in input as it is very rare when this happens. 回答1: I'm assuming you have a line somewhere in your code like: HttpWebResponse response = request.GetResponse() as HttpWebResponse; Simply replace it with this: HttpWebResponse response; try { response = request.GetResponse() as HttpWebResponse; } catch (WebException ex) { response = ex.Response as HttpWebResponse; } 回答2: try {

问题 I see many examples but all of them read them into byte arrays or 256 chars at a time, slowly. Why? Is it not advisable to just convert the resulting Stream value into a string where I can parse it? 回答1: You should create a StreamReader around the stream, then call ReadToEnd . You should consider calling WebClient.DownloadString instead. 回答2: You can use StreamReader.ReadToEnd() , using (Stream stream = response.GetResponseStream()) { StreamReader reader = new StreamReader(stream, Encoding

问题 I am initiating an HttpWebRequest and then retrieving it's response. Occasionally, I get a 500 (or at least 5##) error, but no description. I have control over both endpoints and would like the receiving end to get a little bit more information. For example, I would like to pass the exception message from server to client. Is this possible using HttpWebRequest and HttpWebResponse? Code: try { HttpWebRequest webRequest = HttpWebRequest.Create(URL) as HttpWebRequest; webRequest.Method =

问题 Im wondering if theres an easy way to get the response of an async httpwebrequest. I have already seen this question here but all im trying to do is return the response (which is usually json or xml) in the form of a string to another method where i can then parse it/ deal with it accordingly. Heres some code: I have these two static methods here which i think are thread safe as all the params are passed in and there are no shared local variables that the methods use? public static void

问题 Is there any way I can hook Fiddler up to capture requests and responses made using .NET HttpWebRequest and HttpWebResponse? 回答1: The Fiddler FAQ gives the answer to this. You essentially route your HTTP traffic through Fiddler (i.e. Use Fiddler as a proxy). Here's some links that will help: Fiddler Web Debugging - Configuring Clients Which in turn links to here: Take the Burden Off Users with Automatic Configuration in .NET You can achieve this via some configuration settings in the web

问题 I'm successfully passing data between a handheld device (Compacted Framework/Windows CE) and a modern (not "modern" as in Windows 8, but as in 21st Century) server app (Web API). However, after the (successful) passing of data, the client fails with the err msg, " This operation cannot be performed after the request has been submitted " Which operation is it complaining about? Here's my client code: public static HttpWebResponse SendXMLFile(string xmlFilepath, string uri) { StringBuilder sb =

问题 I have the function to check if website is available. public bool ConnectionAvailable(string strServer) { try { HttpWebRequest reqFP = (HttpWebRequest)HttpWebRequest.Create(strServer); reqFP.Timeout = 10000; HttpWebResponse rspFP = (HttpWebResponse)reqFP.GetResponse(); if (HttpStatusCode.OK == rspFP.StatusCode) { // HTTP = 200 - Internet connection available, server online rspFP.Close(); return true; } else { // Other status - Server or connection not available rspFP.Close(); return false; }

问题 I posted a question here that sends an HttpWebRequest, but on looking closer at my method SendHTTPRequestNoCredentials(), which I'm sure I adapted from something I found on StackOverflow some time in the past, it seems as if something's missing. See if this looks fishy to you, when the Http method is Get: public static HttpWebRequest SendHTTPRequestNoCredentials(string uri, HttpMethods method, string data, string contentType) { WebRequest request = null; try { request = WebRequest.Create(uri)

问题 I´m making repeated requests to a web server using HttpWebRequest, but I randomly get a 'broken' response stream in return. e.g it doesn´t contain the tags that I KNOW is supposed to be there. If I request the same page multiple times in a row it turns up 'broken' ~3/5. The request always returns a 200 response so I first thought there was a null value inserted in the response that made the StreamReader think it reached the end. I´ve tried: 1) reading everything into a byte array and cleaning
