content-length

问题 I would like to know how much data was sent in response to a certain http-request. What I currently do is this: HttpURLConnection con = (HttpURLConnection) feedurl.openConnection(); //check the response for the content-size int feedsize = con.getContentLength(); The problem is, that content-legnth is not always set. E.g. when the server uses transfer-encoding=chunked I get back a value of -1. I do not need this to display progress information. I just need to know the size of the data that was

问题 I'm trying to figure why the Content-Length header of php gets overwritten. This is demo.php <?php header("Content-Length: 21474836470");die; ?> a request to fetch the headers curl -I http://someserver.com/demo.php HTTP/1.1 200 OK Date: Tue, 19 Jul 2011 13:44:11 GMT Server: Apache/2.2.16 (Debian) X-Powered-By: PHP/5.3.3-7+squeeze3 Content-Length: 2147483647 Cache-Control: must-revalidate Content-Type: text/html; charset=UTF-8 See Content-Length ? It maxes out at 2147483647 bytes, that is 2GB.

问题 We have a reverse proxy server running on wwwdev.example.com, and we have the full site running on dev.example.com. If I go to dev.example.com/scripts/jquery-version.js, I get the full jQuery-version.js file returned, ending like this: if ( typeof define === "function" && define.amd && define.amd.jQuery ) { define( "jquery", [], function () { return jQuery; } ); } })( window ); If I go to wwwdev.example.com/scripts/jquery-version.js, the file is cut off before it completes: if ( typeof define

问题 I'm using java's HTTP Server object with web service implemeted by WebServiceProvider. I see that no matter of the client request, the answer is chunked and i need it to be with content length. so i'm assuming the problem is in the server and not the web server provider, right? and how can i configure the http header to use content length and not chunked? HttpServer m_server = HttpServer.create(); Endpoint ep= Endpoint.create(new ep()); HttpContext epContext = m_server.createContext("

问题 I am using Ruby on Rails 3 and in a my view file I have this code: <%= form_for (@account, ...) do |f| %> <%= f.file_field :file %> ... <%= f.submit "Upload" %> <% end %> In order to avoid an overloading of the server, I would check the size of the uploading file before that the server receives it. This is because, pressing the submit button of the form, the server first will entirely receive the file and after will check the file. I know that a HTTP request has header fields, so I would like

问题 Please forgive my lack of understanding on this subject. I had bunch of urls that I am interested to know the size of its web page. So, I used HTTP Head req method to get the Content-Length. I verified the Content-Length values generated from Head method by opening some of those urls in a browser (I used Firefox) and checking the "View Page Info" (from right-click on website in browser) option that gives the "Size:". For most of the urls, both the values matches but not for some. I wonder why

问题 i'm using code like this: //section with the important stuff for the client ob_start(); echo "Blah... Random Content" . rand(1,1000); $size = ob_get_length(); header("Content-Length: $size"); header('Connection: close'); ob_end_flush(); ob_flush(); flush(); //all the following output/script running time should be ignored by the client (file_get_contents()) sleep(10); echo "long action completed"; to output some content and subsequently running a time consuming background job. In a other file

问题 I've a big compressed file and I want to know the size of the content without uncompress it. I've tried this: import gzip import os with gzip.open(data_file) as f: f.seek(0, os.SEEK_END) size = f.tell() but I get this error ValueError: Seek from end not supported How can I do that? Thx. 回答1: It is not possible in principle to definitively determine the size of the uncompressed data in a gzip file without decompressing it. You do not need to have the space to store the uncompressed data -- you

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . Google displayed a 411 error, but I already put the Content-Length in the header. How do I fix this error? $authToken = getAuthorizationToken(); $xml_data = '<?XML version="1.0"?> <Batch> <Remove> <Promotions>

问题 i have the following struct defined: typedef struct PList{ Person person; struct PList *nextPerson; // set to NULL by default <<<<< }PList; and this method: int length(struct PList* db){ PList* cur = db; int size = 0; while (cur != NULL){ ++size; cur = cur->nextPerson; } return size; } error: conflicting types for 'length' is being thrown at the signature for the length method. Any ideas? 回答1: That actually means that there is another function/declaration called length elsewhere in your
