obtaining response charset of response to get or post request

家住魔仙堡 提交于 2019-12-05 06:04:15
I am working to extract response charset in a java web app, where I am using Apache HTTP Client. For example, one possible value obtained from "Content-Type" header is text/html; charset=UTF-8 Then my code will extract all text after the "=" sign... So the charset as extracted will be UTF-8 I just wanted to know, is the above method for obtaining response charset correct? Or is there some scenario where the above code will not work? Is there something I am missing here? forty-two Doesn't httpclient (or http core) already provide that functionality? Something like this: HttpResponse response =

问题 I saw that there was a similar question but could not find proper answer .. Any new answer would be greatly appreciated. 回答1: Try this: Define a Filter that adds response headers: import com.google.common.collect.HashMultimap; import com.google.common.collect.Multimap; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax

Is there a size limit for HTTP response headers on Google App Engine?

心不动则不痛 提交于 2019-12-05 05:21:46
I was trying to run a profiler on some handler code up on appspot and was looking for a way to show the pstats output without writing directly to the response body (which is problematic for handlers responding with structured data such as JSON). I decided to try writing the output to the response header, and added some js to my html-rendering handlers that could parse the header and console.log() it (turned out to be pretty simple and convenient to work with). For the non-html rendering handlers, I was thinking I might try and build a chrome extension to do something similar, but of course,

Adding favicon through a http header

こ雲淡風輕ζ 提交于 2019-12-05 05:20:26
Let's assume that I want to add a favicon on a dynamically generated page (specifically an ADF Faces page, but this is irrelevant). I can't modify a tag of my resulted html. So I try to add a http-header in servlet header. I want my header to be identical to html head element: <link rel="shortcut icon" href="http://foo.com/favicon.ico"> I'm adding it this way: httpResponse.addHeader("Link", "<http://foo.com/favicon.ico>; rel=\"shortcut icon\""); And in my browser I see this header in response: Link: <http://foo.com/favicon.ico>; rel="shortcut icon" But, unfortunately, this does not have any

“Content-Type:text/plain” forces to download the file

三世轮回 提交于 2019-12-05 04:51:15
If I call header('Content-Type:text/plain; charset=ISO-8859-15'); the browser will download the file instead of showing it. Using text/html works instead. (the downloaded file is processed anyway, it's not downloading the source code) I've tried to add header('Content-Disposition:inline;'); but it was just ignored. I'm pretty clueless about what could cause this problem, any tip? The server is MAMP 1.9.6 (PHP 5.3.5, Apache/2.0.64). edit: this only happens on Chrome, it works on Firefox, Camino and Safari. I cannot reproduce this with this script: <?php header('Content-Type:text/plain; charset

HTTP: How should I respond to “Range: bytes=” when Range is unsupported?

僤鯓⒐⒋嵵緔 提交于 2019-12-05 04:40:17
What is the correct response to a GET request with the header field Range: bytes=278528- if Range is not supported? Reading the HTTP header definitions ( http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html ) i think i should at least set: Accept-Ranges: none , but it clearly states that Clients MAY generate byte-range requests without having received this header for the resource involved. So, if a client requests a range, should I: Reply with the whole file from byte 0? Reply with some status error? (400/406/416/501) see: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html You may ignore

How to return response header field to main method using Google Volley for HTTP GET request in Android / Java?

给你一囗甜甜゛ 提交于 2019-12-05 04:24:40
I'm using google volley for networking in android. I will make a http GET request and need to return a response header value. I found some answers on stack overflow to access the header fields, but don't know how to return it to my calling spot. Please have a look at my code, I put four numbers in it to explain my problem. At (1) I can print out the value which I need. Than I've tried to save it in a class attribute (2) and there is no error in the IDE. If I want to return it from there (3), I got a NullPointerException at (4). Maybe its a read before write problem there. So how can I get the

Tornado - What is the difference between RequestHandler's get_argument(), get_query_argument() and get_body_argument()?

别来无恙 提交于 2019-12-05 04:18:03
When to use RequestHandler.get_argument() , RequestHandler.get_query_argument() and RequestHandler.get_body_argument() ? What is the use-case for each of them? Also what does the request.body and request.argument do in these cases? Which are to be used in which scenarios? And, is there a request.query or something similar too? Most HTTP requests store extra parameters (say, form values) in one of two places: the URL (in the form of a ?foo=bar&spam=eggs query string ), or in the request body (when using a POST request and either the application/x-www-form-urlencoded or multipart/form-data mime

Why does Google Chrome NOT use cached pages when I define the HTTP “Expires” header

天大地大妈咪最大 提交于 2019-12-05 04:03:17
I am sending validly formatted HTTP response "Expired" headers (e.g. "Wed, 04 May 2011 09:29:09 GMT") with a page served through https://[host]:{port}/ (with [host] being localhost) from a J2EE application, using response.setDateHeader("Expires", {milliseconds a few seconds in the future} ) . On my pages I have a link to the same page. When I click this link from within Firefox (4) or IE (8), the page is reloaded from cache until the Expired time is reached. Once the Expired time is passed, clicking on the same link results in the page being loaded from the server with fresh data. If I hit F5
