Perl Apache : Perl script displayed as plain text

阅读更多关于 Perl Apache : Perl script displayed as plain text

While configuring with apache and perl cgi scripts , don't know why index.cgi / index.pl are displayed as plain text instead of executing them. When I put http://localhost in browser it displays below code, instead of executing it. List item #!C:/Dwimperl/perl/bin/perl.exe -w print "Content-type: text/html\n\n"; print <<HTML; <html> <head> <title>A perl web page</title> </head> <body> <h3>A hello world form perl</h3> </body> HTML exit; This are parts of httpd.conf file which I have edited most of the times (after reading various online reference, tutorials) # This should be changed to whatever

Display the result on the webpage as soon as the data is available at server

I am writing a cgi page in Python. Let's say a client sends request to my cgi page. My cgi page does the calculation and as soon as it has the first output, it sends back that output to the client, but it will CONTINUE to do the calculation and send other responses AFTER the first response is sent. Is what I have presented here possible? I ask this question because in my limited knowledge, in a cgi page responses are sent back on one-time basic, once a response is sent, cgi-page stops running. This thing is made on server side or client side, and how do I implement it? My server is running

How can I send POST and GET data to a Perl CGI script via the command line?

阅读更多关于 How can I send POST and GET data to a Perl CGI script via the command line?

I am trying to send a get or a post through a command-line argument. That is test the script in the command line before I test through a browser (the server has issues). I tried searching online, and I suppose I was probably using incorrect terminology because I got nothing. I know this is possible because I saw someone do it. I just don't remember how it was done. Thanks! :) Are you using the standard CGI module? For example, with the following program (notice -debug in the arguments to use CGI ) #! /usr/bin/perl use warnings; use strict; use CGI qw/ :standard -debug /; print "Content-type:

How can I serve unbuffered CGI content from Apache 2?

阅读更多关于 How can I serve unbuffered CGI content from Apache 2?

问题 I would like to be able to allow a user to view the output of a long-running GCI script as it is generated rather than after the script is complete. However even when I explicitly flush STDOUT the server seems to wait for the script to complete before sending the response to the client. This is on a Linux server running Apache 2.2.9. Example python CGI: #!/usr/bin/python import time import sys print "Content-type: text/plain" print for i in range(1, 10): print i sys.stdout.flush() time.sleep

php-fpm搭建及加固

阅读更多关于 php-fpm搭建及加固

php-fpm安装 nginx本身不能处理PHP，它只是个web服务器，当接收到请求后，如果是php请求，则发给php解释器处理，并把结果返回给客户端。 nginx一般是把请求发fastcgi管理进程处理，fascgi管理进程选择cgi子进程处理结果并返回被nginx。那什么又是cgi呢？ CGI(Common Gateway Interface)。CGI是外部应用程序（CGI程序）与Web服务器之间的接口标准，是在CGI程序和Web服务器之间传递信息的规程。CGI规范允许Web服务器执行外部程序，并将它们的输出发送给Web浏览器，CGI将Web的一组简单的静态超媒体文档变成一个完整的新的交互式媒体。简单的说，就是：cgi就是专门用来和web 服务器打交道的。web服务器收到用户请求，就会把请求提交给cgi程序（php的fastcgi），cgi程序根据请求提交的参数作应处理（解析php），然后输出标准的html语句返回给web服服务器，再返回给客户端，这就是普通cgi的工作原理。安装 yum安装 yum install php php-mysql php-fpm 安装成功。 php-fpm配置文件路径：/etc/php-fpm.d/www.conf php配置文件路径：/etc/php.ini 说明： php-mysql，这个是后续链接mysql需要的修改php配置 php

Webpage redirect to the main page with CGI Python

阅读更多关于 Webpage redirect to the main page with CGI Python

As my first web app I developed a very simple survey. Random questions are being asked from the user anytime the page refreshes. The answer is sent to a cgi script using post to save the answers to the database. However, when the user presses the submit button it automatically goes to the page which is responsible for processing the data and since it doesn't have any output it is a blank page. Now if the user wants to answer another question they have to press the "back" in the browser and refresh the page so a new question pops up. I don't want this. I want it in a way that when the users

How can I fork a background processes from a Perl CGI script on Windows?

阅读更多关于 How can I fork a background processes from a Perl CGI script on Windows?

I've had some trouble forking of processes from a Perl CGI script when running on Windows. The main issue seems to be that 'fork' is emulated when running on windows, and doesn't actually seem to create a new process (just another thread in the current one). This means that web servers (like IIS) which are waiting for the process to finish continue waiting until the 'background' process finishes. Is there a way of forking off a background process from a CGI script under Windows? Even better, is there a single function I can call which will do this in a cross platform way? (And just to make

Redirect Standard Output Efficiently in .NET

阅读更多关于 Redirect Standard Output Efficiently in .NET

I am trying to call php-cgi.exe from a .NET program. I use RedirectStandardOutput to get the output back as a stream but the whole thing is very slow. Do you have any idea on how I can make that faster? Any other technique? Dim oCGI As ProcessStartInfo = New ProcessStartInfo() oCGI.WorkingDirectory = "C:\Program Files\Application\php" oCGI.FileName = "php-cgi.exe" oCGI.RedirectStandardOutput = True oCGI.RedirectStandardInput = True oCGI.UseShellExecute = False oCGI.CreateNoWindow = True Dim oProcess As Process = New Process() oProcess.StartInfo = oCGI oProcess.Start() oProcess.StandardOutput

Deploy flask application on 1&1 shared hosting (with CGI)

阅读更多关于 Deploy flask application on 1&1 shared hosting (with CGI)

I've written a web application for my sports club with the flask web framework. I did everything on my local machine with the build-in test server. Know they told me to deploy it on an 1&1 shared hosting web space. They have python support but it seems like they only allow CGI to run python scripts. I tried this tutorial: flask via CGI I ignored the rewrite stuff until now. All requests to my CGI script resulted in a 404 error. I modified my 404 handler in the application to return request.path . When I request /foo/runserver.cgi/ it returns / as output. I have no idea why it doesn't serve the

Python os module open file above current directory with relative path

阅读更多关于 Python os module open file above current directory with relative path

问题 The documentation for the OS module does not seem to have information about how to open a file that is not in a subdirectory or the current directory that the script is running in without a full path. My directory structure looks like this. /home/matt/project/dir1/cgi-bin/script.py /home/matt/project/fileIwantToOpen.txt open("../../fileIwantToOpen.txt","r") Gives a file not found error. But if I start up a python interpreter in the cgi-bin directory and try open("../../fileIwantToOpen.txt","r
