问题 Why the output of this simple Perl script >> print "Content-type: text/plain\n"; print "Transfer-Encoding: chunked\n\n"; print "11\n\n"; print "0123456789ABCDEF\n"; print "11\n\n"; print "0123456789ABCDEF\n"; print "0\n\n"; ...works for Chrome browser and does not for IE10..? 回答1: You’ve implemented the chunked transfer coding wrong: Each chunk consists of the chunk size in bytes in hexadecimal notation, followed by a CRLF sequence, followed by the chunk data: chunk = chunk-size [ chunk

问题 This question already has answers here : How to fix “Headers already sent” error in PHP (11 answers) Closed 6 years ago . Complete error: Warning (2): Cannot modify header information - headers already sent by (output started at /Applications/XAMPP/xamppfiles/htdocs/trunk/dafe/cake/basics.php:355) [CORE/cake/libs/controller/controller.php, line 743] As far as I can tell it happens after I try to redirect. I know it's caused by a whitespace but I can't find it anywhere, where does this error

问题 I have some JavaScript from a 3rd party vendor that is initiating an image request. I would like to figure out the URI of this image request. I can load the page in my browser, and then monitor "Live HTTP Headers" or "Tamper Data" in order to figure out the image request URI, but I would prefer to create a command line process to do this. My intuition is that it might be possible using python + qtwebkit, but perhaps there is a better way. To clarify: I might have this (overly simplified code)

问题 I'm looking at creating an anonymous poll. However, I want to prevent users from voting twice. I was thinking of hashing some request.META values like so: from hashlib import md5 request_id_keys = ( 'HTTP_ACCEPT_CHARSET', 'HTTP_ACCEPT', 'HTTP_ACCEPT_ENCODING', 'HTTP_ACCEPT_LANGUAGE', 'HTTP_CONNECTION', 'HTTP_USER_AGENT', 'REMOTE_ADDR', ) request_id = md5('|'.join([request.META.get(k, '') for k in requst_id_keys])).hexdigest() My questions: Good idea? Bad idea? Why? Are some of these keys

问题 I'm using a proxy service (proxymesh) that puts useful information into the headers sent in response to a CONNECT request. For whatever reason, Python's httplib doesn't parse them: > CONNECT example.com:443 HTTP/1.1 > Host: example.com:443 > < HTTP/1.1 200 Connection established < X-Useful-Header: value # completely ignored < The requests module uses httplib internally, so it ignores them as well. How do I extract headers from a CONNECT request? 回答1: Python's httplib actually ignores these

问题 I mocking my API using Apiary.io. But somehow I cannot read any headers from response object using angularJS. And I am sure i have at least Content-Type: application/json correctly set-up by checking in firebug. Code in Angular should read headers correctly too as i can print them when sending request to somewhere else than apiary.io... $http.get('http://ies.apiary.io/some').then(function(response) { console.log("ok",response.headers('Content-Type')); },function(response){console.log("err"

问题 I am working on a simple download application. While making a request for the following file both firefox and my application doesn't get the content-length field. But if i make the request using wget server does send the content-length field. I did change wgets user agent string to test and it still got the content-length field. Any ideas why this is happening? wget request ---request begin--- GET /dc-13/video/2005_Defcon_V2-P_Zimmerman-Unveiling_My_Next_Big_Project.mp4 HTTP/1.0 User-Agent:
