情到浓时终转凉″ 提交于 2019-12-07 06:58:14
问题 I'm coding a small website with Python and CGI where users can upload zip files and download files uploaded by other users. Currently I'm able to upload correctly the zip's, but I'm having some trouble to correctly send files to the user. My first approach was: file = open('../../data/code/' + filename + '.zip','rb') print("Content-type: application/octet-stream") print("Content-Disposition: filename=%s.zip" %(filename)) print(file.read()) file.close() But soon I realized that I had to send

常用编程语言介绍及各语言特点

一,编程语言 计算机语言的种类非常的多,总的来说可以分成机器语言,汇编语言,高级语言三大类。计算机每做的一次动作,一个步骤,都是按照已经用计算机语言编好的程序来执行的,程序是计算机要执行的指令的集合,而程序全部都是用我们所掌握的语言来编写的。所以人们要控制计算机一定要通过计算机语言向计算机发出命令。 通用的编程语言有两种形式:汇编语言和高级语言。 1.1汇编语言 汇编语言的实质和机器语言是相同的,都是直接对硬件操作,只不过指令采用了英文缩写的标识符,更容易识别和记忆。它同样需要编程者将每一步具体的操作用命令的形式写出来。汇编程序通常由三部分组成:指令、伪指令和宏指令。汇编程序的每一句指令只能对应实际操作过程中的一个很细微的动作,例如移动、自增,因此汇编源程序一般比较冗长、复杂、容易出错,而且使用汇编语言编程需要有更多的计算机专业知识,但汇编语言的优点也是显而易见的,用汇编语言所能完成的操作不是一般高级语言所能实现的,而且源程序经汇编生成的可执行文件不仅比较小,而且执行速度很快。 1.2高级语言 高级语言是绝大多数编程者的选择。和汇编语言相比,它不但将许多相关的机器指令合成为单条指令,并且去掉了与具体操作有关但与完成工作无关的细节,例如使用堆栈、寄存器等,这样就大大简化了程序中的指令。同时,由于省略了很多细节,编程者也就不需要有太多的专业知识。 高级语言主要是相对于汇编语言而言

问题 How can I run my perl CGI script without apache? This is for testing purposes, so some kind of single-process server that processes only one request at time should be enough for me. 回答1: Script shoud be run as specific user and currently I do not want to setup suexec on testing apache . There is nothing preventing you from duplicating the requisite Apache configuration except for the user under which httpd is going to be run, the interface/port to bind to and possibly the cgi-bin directory

CGI::Session sharing sessions between clients!

大兔子大兔子 提交于 2019-12-07 05:04:30
问题 When I tried this: while (my $cgi = new CGI::Fast) { ... my $session = CGI::Session->new(undef, $cgi); ... } I discovered that different clients were getting the same session! What would be causing this bizarre session-sharing? EDIT: I can't reproduce this reliably but in my testing, I have seen cases where I delete the session cookie from the browser, refresh the page, and (using Firebug's Net pane) see that I'm not sending a cookie in the request but get a Set-Cookie in the response with an

For example it doesn't contain SUMMARY section. Is there a correct way to

问题 I was using stackoverflow for a while now and it helped me very often. Now I have a problem I couldn't solve myself or through searching. I'm trying to output my excel file generated by openpyxl in browser as I was doing it with phpexcel. The method appears to be the same, but I only get broken file. My code looks like this: from openpyxl.workbook import Workbook from openpyxl.writer.excel import ExcelWriter from openpyxl.writer.excel import save_virtual_workbook from openpyxl.cell import get

Running Python CGI Scripts from Javascript and JQuery Mobile UI

♀尐吖头ヾ 提交于 2019-12-06 15:39:54
问题 The workflow I'm trying to accomplish is as follows. There is a jQuery Mobile UI with a bunch of range slider elements. Each one is for controlling a different function. When a user moves and releases any one of these sliders, a jQuery event should be triggered that makes an AJAX call (I don't care if it uses JSON, XML, POST, etc - fastest is best) The Ajax call contains info about what slider was moved, and what its new value is (ex: id=slider1, value=215) The Ajax executes a python script
