GET vs. POST (form processing)

阅读更多关于 GET vs. POST (form processing)

问题 I completely understand the differences between the two in terms of form handling, user discretion and privacy of data, but in what situation would anyone rather use GET over POST when sending form results? Thanks 回答1: GET places parameters in the URL itself, allowing everyone to see. While POST would be ideal for logins and security-sensitive data, GET is ideal when you want a dynamic page to be bookmarked. Take a forum for example. The thread which shows all posts within it is loaded

difference between cin.get() and cin.getline()

问题 I am new to programming, and I have some questions on get() and getline() functions in C++. My understanding for the two functions: The getline() function reads a whole line, and using the newline character transmitted by the Enter key to mark the end of input. The get() function is much like getline() but rather than read and discard the newline character, get() leaves that character in the input queue. The book(C++ Primer Plus) that I am reading is suggesting using get() over getline() . My

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?

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).

Correct syntax for hyperlink URL with PHP $_GET

阅读更多关于 Correct syntax for hyperlink URL with PHP $_GET

I am wondering how I would put information from my website in the URL on the first page of my site, and then on the next page, use $_GET to get the variables from the URL. I was just wanting to put it in a link like <a href="mywebsite.com/page?name=$name"></a> So would it work if I did it like that, and if it would, how would I get it from the URL? do <a href="http://mywebsite.com/page?name=<?php echo $name; ?>"></a> And in your page, you could get the name as: $name = $_GET['name']; Example Link: http://example.com/page.php?name=Charles If you used $_GET["name"] it would return the value

PHP $_GET and $_POST undefined problem

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_query.php"); } ?> When this page executes, the following error is always shown: PHP Notice: Undefined

How do I download zip file in C#?

阅读更多关于 How do I download zip file in C#?

问题 I use HTTP GET that downloads a zip file in a browser, something like https://example.com/up/DBID/a/rRID/eFID/vVID (not the exact url) Now, when I try to do the same download in C# code(same GET method as above) for a desktop application, the zip file downloaded is not a valid archive file. When I opened this file in notepad, it was some HTML page. I think I'm not setting some header correctly. I looked around for examples. I'd found several wrt uploads, but did not see anything for downloads
