http-headers

问题 I'd like to send headers with PHP, inside of a javascript condition. Is that possible? if ($('body').hasClass('browserChrome')) { <?php header("Content-Type: application/x-chrome-extension"); header('Content-Disposition: attachment; filename="http://example.com/file.crx"'); header("Pragma: no-cache"); header("Expires: 0"); ?> } 回答1: That won't work. First, your web server will execute the PHP script, resulting in an HTML page with JavaScript. That is then sent to the user's web client, which

问题 When I call apache_request_headers() in php to get the X-Forwarded-For header, it blanks out any and all page output. What am I doing wrong? $header = apache_request_headers(); $ip = $header["X-Forwarded-For"]; If I comment out those two lines it works just fine, except for the obvious issue that now $ip isn't being set. Thanks for your help! 回答1: From the manual, its probably this: "This function is only supported when PHP is installed as an Apache module." Try $_SERVER['HTTP_X_FORWARDED_FOR

问题 I saw this plugin which download files using Ajax and some other fallback techniques. But since ajax download file feature is not supported in all browsers , he used a trick with Iframe. ( which is pretty easy to implement) But one thing caught my eye : He also added an option which tells you when the file has finished download. He did it via cookie . He polls to see if the cookie via setInterval . as long as the cookie does not exist - the file wasn't finish download.( and when the cookie is

问题 When running with Kerberos tickets, I have noticed that every firefox request has a different Authorization line in the HTTP header. I loaded a simple page, then hit the reload button several times and it was never the same. What causes this behavior? I would have thought that the Authorization line would stay constant for the duration of the Kerberos credentials. (Note that I got the credentials via the kinit command before firing up firefox.) When the authentication method is Basic, then

问题 I'm trying to craft a very specific HTTP request to a server (ie. defining the exact set of HTTP headers), but NSURLSession keeps "helpfully" inserting a bunch of HTTP headers like Accept , Accept-Language and Accept-Encoding . Consider the following playground (Swift 2.x) which sends a request to a service that just echos the HTTP headers that were sent: import Foundation import XCPlayground XCPlaygroundPage.currentPage.needsIndefiniteExecution = true let url = NSURL(string: "http://httpbin

问题 I'm maintaining a web site for a non-profit organisation. I'm not the one who designed this web site, and I don't know the person who did it. That said, I have an issue with IE9. I will eventually try to correct it, but meanhile just adding the X-UA-Compatible header so IE9 turns to IE8 mode would work just fine. In an asp.net web site, I would add it in the web.config with the <customHeaders> element (with IIS7). Is there's a way to send this header for all file in a php web site, without

问题 I'm uploading a csv file to Django via ajax, using Django Rest Framework. I have everything working, but data from the request headers is included with the file content. I was expecting these headers to have been stripped from the file content, so the file would look exactly like the uploaded file. Any ideas? ... Django View class FileUploadView(APIView): parser_classes = (FileUploadParser, ) def post(self, request, format=None): file = request.FILES['file'] fs = FileSystemStorage() fs.save(
