How can we parse HTTP response header fields using Qt/C++?

戏子无情 提交于 2019-12-06 05:20:32
I am writing a piece of software that uses Qt/KDE libs. The objective is to parse the HTTP header response fields into different fields of a struct. So far the HTTP header response is contained in a QString. It looks something like this: "HTTP/1.1 302 Found date: Tue, 05 Jun 2012 07:40:16 GMT server: Apache/2.2.22 (Linux/SUSE) x-prefix: 49.244.80.0/21 x-as: 23752 x-mirrorbrain-mirror: mirror.averse.net x-mirrorbrain-realm: region link: <http://download.services.openoffice.org/files/du.list.meta4>; rel=describedby; type="application/metalink4+xml" link: <http://download.services.openoffice.org

Simulate file form submission with XMLHttpRequest Level 2

你。 提交于 2019-12-06 05:20:18
On my current page I use old file upload with input element. However, now I've implemented drag&drop from that very nice series of articles: http://www.sitepoint.com/html5-file-drag-and-drop/ There's one snag. Before rewriting the page I was submitting the form with the file and server side service (Java's appspot.com) did all the magic of retrieving the file, saving to DB etc. I would still like to take advantage of that service. However now, after rewriting the file upload to use XMLHttpRequest my code simply writes file to the content, whereas service expects form. Is there a way to mimick

twisted location header redirect

邮差的信 提交于 2019-12-06 04:41:38
From the render_GET method of a Resource in twisted , is it possible to redirect to a different url entirely (hosted elsewhere) request.redirect(url) doesn't appear to do anything, and neither does twisted.web.util.Redirect The equivalent in php would be, header('location:'.$url); EDIT this is the code I'm running from twisted.web import server, resource from twisted.internet import reactor class Simple(resource.Resource): isLeaf = True def render_GET(self, request): request.redirect("www.google.com") request.finish() site = server.Site(Simple()) reactor.listenTCP(8080, site) reactor.run() I

Correct HTTP Headers for Images?

无人久伴 提交于 2019-12-06 04:40:41
问题 I'm writing a web server in C#, just for the fun of it, and I am able to serve basic text files to my browser. However, when serving up an image (say, image.png ), all browsers that I test my server on (IE, Firefox, and Chrome) show some kind of placeholder thumbnail for the image, as if the image is corrupted or invalid. The response that I am sending to the browser looks like HTTP/1.0 200 Ok Content-Type: image/png Content-Length: 14580053 {image data here} Am I using the correct HTTP

How to Modify HTTP Header of a request using C#?

独自空忆成欢 提交于 2019-12-06 04:17:46
问题 I was trying to modify a HTTP Header using C#. I tried to manipulate the Request.Headers on Page preinit event. But when i try to set anything to the Headers, i get PlatformNotSupportedException. Since We can not set a new NameValueCollection to Reqeust.Headers, I tried to set the value using following code: Request.Headers.Set(HttpRequestHeader.UserAgent.ToString(), "some value"); Any idea how can this be achieved? 回答1: Try this: HttpContext.Current.Request.Headers["User-Agent"] = "Some

YouTube not showing as a referrer?

生来就可爱ヽ(ⅴ<●) 提交于 2019-12-06 03:16:32
I've been tracking referrers to my site and storing it a session to be used in some reports when they do certain actions. To get the referrer, I just do $_SESSION["s1"] = $_SERVER["HTTP_REFERER"]; It seems to work for everything except YouTube. Clicking a link on YouTube generates a blank referrer. What could cause this? Does YouTube do something to the headers? Does opening a new window lose the referrer info? I came across this same issue today. Even though this question is 5 years old it came up first on Google when I searched for the cause; so I am going to answer it here for others who

How to disable browser caching in Vaadin

余生长醉 提交于 2019-12-06 02:59:54
问题 My question is short (and hopefully simple to solve!): How can I completely disable browser-caching in my webservice realized with vaadin ? I want to completely disable caching since I'm getting problems when I try to do some PDF streaming and displaying them in my browers. I have read about a solution for my problem for example here: Using <meta> tags to turn off caching in all browsers? They talk about adding some headers to the web application that disable browser caching. But how do I add

Is it possible to attach file in POST Json?

喜你入骨 提交于 2019-12-06 02:40:15
I have a heap of data in format JSON(Serialized object). I send this data to server by POST method with header: Content-Type: application/json . Is it possible to attach file to body request and send at once. Or JSON data sugggests sending only text data? Try to send the file inside the json object as a base64 string: { "file":"dGhpcyBpcyBhIGZpbGUgc2FtcGxl..." } Later you can open the file with something like: document.location = 'data:application/pdf;base64,' + file In this context, the content-type header aims to describe the type of data in the request body. If you use application/json the

How to re-order HTTP headers?

青春壹個敷衍的年華 提交于 2019-12-06 02:01:29
I was wondering if there was any way to re-order HTTP headers that are being sent by our browser, before getting sent back to the web server? Since the order of the headers leaves some kind of "fingerprinting", see this post and this post , I was thinking about using MITMProxy (with Inline Scripting, I guess) to modify headers on-the-fly. Is this possible? How would one achieve that? Note: I'm looking for a method that could be scripted, not a method using a graphical tool like the Burp Suite (although Burp is known to be able to re-order headers) I'm open to suggestions. Perhaps NGINX might

What is the “raw HTTP header”? What is the difference between “HTTP header” and “raw HTTP header”?

心已入冬 提交于 2019-12-06 01:38:54
问题 In Zend Framework in Response Class there are two different arrays for storing headers: _headers[] and _headersRaw[] . And there are appropriate methods for setting each one: setHeader(), getHeaders(), clearHeader() and setRawHeader(), getRawHeaders(), clearRawHeaders() . What is the reason to have "header" and "raw header"? Is there some special kind of usage in practice for each of these headers? 回答1: using setHeader you set key vale pair without worrying about there formatting e.g $this-
