问题 function getUrlCurrently() { $pageURL = (@$_SERVER["HTTPS"] == "on") ? "https://" : "http://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } return $pageURL; } I'm using this function to determine the current URL of the page.

问题 I have a question, i want to make some search page, and it needs a get variable to sort the results. So if someone enters the page without that GET variable, reload the page and make it appear, for example you enter www.myweb.com/search and automatically reloads and changes to www.myweb.com/search/?sort=ascending (because that variable is necessary) . I hope you understand me, good bye 回答1: I think this will work for what you're looking to do: if (empty($_GET['sort'])) { header('Location: ' .

问题 I trying get text data from internet with C++ but I couldn't find anything useful. like python; import urllib data = urllib.urlopen("examplesite.com/data.txt").read() 回答1: Take a look at libcurl. It is a C library, with C++ bindings. The libcurl website includes a collection of examples in C, including one that copies a URL to a block of memory, getinmemory.c For C++, the main page of the curlcpp binding at https://github.com/JosephP91/curlcpp shows an example of downloading a URL to a file.

问题 I have seen this method being used on about three sites now, including Facebook, Dropbox and Microsoft's Skydrive. It works like this. Let's say you want to look at the image without downloading, then you'd just do this. https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-xxxx/xxx_xxxxxxxxxxxxxxx_xxxxxxxxx_o.jpg But if I want to download it, I'd add ?dl=1 https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-xxxx/xxx_xxxxxxxxxxxxxxx_xxxxxxxxx_o.jpg?dl=1 Easy peasy right? Well, it's probably not easy on

问题 We just redesigned a web application and as a result we've noticed a bug in Chrome (but it supposedly affects all WebKit browsers) that causes a full image/js/css reload after a Post/Redirect/Get. Our app is built using ASP.NET and uses a lot of Response.Redirect's which means users will run into this issue a lot. There's a bug report for the issue with test case: https://bugs.webkit.org/show_bug.cgi?id=38690 We've tried the following to resolve the issue: Change all Response.Redirects to be

问题 I am newer than "egg" in .NET and C# and wanted to test whether I am getting HTTP Response (GET) or not.

问题 What is the best way to implement simple pagination? Here is the code im using to put the items from the database into a table: $sql = "SELECT * FROM table WHERE id='id' "; $result = mysql_query($sql); while($row=mysql_fetch_array($result))} echo($row['id']); echo($row['name']); } I just wanted to pageinate this so i would use $_GET['page'] (bla.php?page=1) to set the offset to 10, then (bla.php?page=2) to set it by 20? 回答1: Simplest answer, add LIMIT to your SQL. LIMIT 10,0 would show first

问题 var transactionID; $.get('http://127.0.0.1/getId', null,function(data) { transactionID = data; alert(transactionID); }); alert(transactionID); The alert inside the get method returns value correctly. However, when the transactionID in the 2nd alert outside of the get method is still null? How to correctly pass out the return data from the get method? 回答1: The $.get is executed asynchronously, i.e. it sends the request to the server and executes the lines after it. So the alert outside will be
