How to download HTTP directory with all files and sub-directories as they appear on the online files/folders list?

阅读更多关于 How to download HTTP directory with all files and sub-directories as they appear on the online files/folders list?

问题 There is an online HTTP directory that I have access to. I have tried to download all sub-directories and files via wget . But, the problem is that when wget downloads sub-directories it downloads the index.html file which contains the list of files in that directory without downloading the files themselves. Is there a way to download the sub-directories and files without depth limit (as if the directory I want to download is just a folder which I want to copy to my computer). 回答1: Solution:

Sanitizing user's data in GET by PHP

阅读更多关于 Sanitizing user's data in GET by PHP

How do you sanitize data in $_GET -variables by PHP? I sanitize only one variable in GET by strip_tags . I am not sure whether I should sanitize everything or not, because last time in putting data to Postgres, the problem was most easily solved by the use of pg_prepare . How do you sanitize data in $_GET -variables by PHP? You do not sanitize data in $_GET. This is a common approach in PHP scripts, but it's completely wrong*. All your variables should stay in plain text form until the point when you embed them in another type of string. There is no one form of escaping or ‘sanitization’ that

问题 I'm new to PHP so I apologize if this is a simple problem... I am moving a PHP site from one server to another. The new server is IIS 7.0, PHP 5.2.1, with short open tag turned "On", and I don't know how the original server was set-up (I was just given the code). The following is the very first section of code on one of the pages: <? ob_start(); session_start(); if($_GET['confirm'] == 13 || $_GET['confirm'] == 14 || $_GET['confirm'] == 15 || $_GET['confirm'] == 16) { include("test/query/test

问题 How do I make an HTTP GET request with parameters in Ruby? It's easy to do when you're POST ing: require 'net/http' require 'uri' HTTP.post_form URI.parse('http://www.example.com/search.cgi'), { "q" => "ruby", "max" => "50" } But I see no way of passing GET parameters as a hash using 'net/http' . 回答1: Use the following method: require 'net/http' require 'cgi' def http_get(domain,path,params) return Net::HTTP.get(domain, "#{path}?".concat(params.collect { |k,v| "#{k}=#{CGI::escape(v.to_s)}" }

I am a newbie, so excuse me if this is a silly question .. So what I was trying is to get the title of a URL using JQuery/JS. I dont want to load the content of the url and then parse tags in it.

How to check if $_GET is empty?

阅读更多关于 How to check if $_GET is empty?

How to check if $_GET is empty? You said it yourself, check that it's empty : if (empty($_GET)) { // no data passed by get } See, PHP is so straightforward. You may simply write, what you think ;) This method is quite secure. !$_GET could give you an undefined variable E_NOTICE if $_GET was unset (not probable, but possible). i guess the simplest way which doesn't require any operators is if($_GET){ //do something if $_GET is set } if(!$_GET){ //do something if $_GET is NOT set } Just to provide some variation here: You could check for if ($_SERVER["QUERY_STRING"] == null) it is completely

Is it possible to preserve plus signs in PHP $_GET vars without encoding?

阅读更多关于 Is it possible to preserve plus signs in PHP $_GET vars without encoding?

问题 Say I request this URL: http://mydomain.com/script.php?var=2+2 $_GET['var'] will now be: "2 2" where it should be "2+2" Obviously I could encode the data before sending and then decode it, but I'm wondering if this is the only solution. I could also replace spaces with plus symbols, but I want to allow spaces as well. I simply want whatever characters were passed, without any url decoding or encoding going on. Thank you! 回答1: Of course. You could read out $_SERVER["QUERY_STRING"] , break it

In my script, requests.get never returns: import requests print ("requesting..") # This call never returns! r = requests.get( "http://www.justdial.com", proxies = {'http': '222.255.169.74:8080'}, ) print(r.ok) What could be the possible reason(s)? Any remedy? What is the default timeout that get uses? What is the default timeout that get uses? The default timeout is None , which means it'll wait (hang) until the connection is closed.
