问题 I am using Spring with DWR . I want to return a file object as response , however I save the file (to be sent) at server temporary location and then send its location as href for anchor tag on client side , however I wonder if there could be a way to throw the file directly to browser on response object without saving it temporarily on server. I expected if there could be a way to send file as a response via DWR. 回答1: public ModelAndView writeFileContentInResponse(HttpServletRequest request,

Using .NET to Post a file to Server HttpWebRequest or WebClient

Okay so here is the deal. As the question states, I'm trying to POST a file to a webserver and am having a few issues. I've tried posting this same file to the same webserver using Curl.exe and have had no issues. I've posted the flags I used with curl just incase they might point out any potential reasons why I'm having trouble with the .NET classes. curl.exe --user "myUser:myPass" --header "Content-Type: application/gzip" --data-binary "@filename.txt.gz" --cookie "data=service; data-ver=2; date=20100212; time=0900; location=1234" --output "out.txt" --dump-header "header.txt" http://mysite

I am trying to get the header "Set-Cookie" or access the cookie container, but the Set-Cookie header is not available. The cookie is in the response header, but it's not there in the client request object. I am registering the ClientHttp stack using bool httpResult = WebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp); Here's the response: HTTP/1.1 200 OK Content-Type: application/xml; charset=utf-8 Connection: keep-alive Status: 200 X-Powered-By: Phusion Passenger (mod_rails/mod_rack) 3.0.0.pre4 ETag: "39030a9c5a45a24e485e4d2fb06c6389" Client-Version: 312, 105, 0, 0 X-Runtime:

Getting JSON data from a response stream and reading it as a string?

I am trying to read a response from a server that I receive when I send a POST request. Viewing fiddler, it says it is a JSON response. How do I decode it to a normal string using C# Winforms with preferably no outside APIs. I can provide additional code/fiddler results if you need them. The fiddler and gibberish images: The gibberish came from my attempts to read the stream in the code below: Stream sw = requirejs.GetRequestStream(); sw.Write(logBytes, 0, logBytes.Length); sw.Close(); response = (HttpWebResponse)requirejs.GetResponse(); Stream stream = response.GetResponseStream();

My app currently uses OAuth to communicate with the Twitter API. Back in December, Twitter upped the rate limit for OAuth to 350 requests per hour. However, I am not seeing this. I am still getting 150 from the account/rate_limit_status method. I was told that I needed to use the X-RateLimit-Limit HTTP header to get the new rate limit. However, in my code, I do not see that header. Here is my code... HttpWebRequest request = (HttpWebRequest)WebRequest.Create(newURL); request.Method = "GET"; request.ServicePoint.Expect100Continue = false; request.ContentType = "application/x-www-form-urlencoded

Concurrency Limit on HttpWebRequest

I am writing an application to measure how fast I can download web pages using C#. I supply a list of unique domain names, then I spawn X number of threads and perform HTTPWebRequests until the list of domains has been consumed. The problem is that no matter how many threads I use, I only get about 3 pages per second. I discovered that the System.Net.ServicePointManager.DefaultConnectionLimit is 2, but I was under the impression that this is related to the number of connections per domain. Since each domain in the list is unique, this should not be an issue. Then I found that the GetResponse()

C# HttpWebResponse Comet problem

风格不统一 提交于 2019-11-30 05:15:32
问题 I am wondering how I would go about reading a persistent connection with HttpWebRequest and HttpWebResponse. The problem seems to be that the GetResponseStream() function waits for the server connection to be closed before returning. Is there an alternative easy way to read a comet connection? Example that doesn't work. // get the response stream Stream resStream = response.GetResponseStream(); string tempString = null; int count = 0; do { // fill our buffer count = resStream.Read(buf, 0, buf
