query-string

问题 Does anyone know if it's possible to make use of URL query's within Laravel. Example I have the following route: Route::get('/text', 'TextController@index'); And the text on that page is based on the following url query: http://example.com/text?color={COLOR} How would I approach this within Laravel? 回答1: Yes, it is possible. Try this: Route::get('test', function(){ return "<h1>" . Input::get("color") . "</h1>"; }); and call it by going to http://example.com/test?color=red . You can, of course

问题 Somewhere in the url there is a &sortBy=6 . How do I update this to &sortBy=4 or &sortBy=2 on a button click? Do I need to write custom string functions to create the correct redirect url?

Response.Redirect(completeUrl); But what I want to do is modify an existing querystring variable. 回答1: To modify an existing QueryString value use this approach: var

问题 I am creating a photo gallery, and would like to be able to change the query string and title when the photos are browsed. The behavior I am looking for is often seen with some implementations of continuous/infinite page, where while you scroll down the query string keeps incrementing the page number (http://x.com?page=4) etc.. This should be simple in theory, but I would like something that is safe across major browsers. I found this great post, and was trying to follow the example with

问题 Although it is strongly recommended (W3C source, via Wikipedia) for web servers to support semicolon as a separator of URL query items (in addition to ampersand), it does not seem to be generally followed. For example, compare http://www.google.com/search?q=nemo&oe=utf-8 http://www.google.com/search?q=nemo;oe=utf-8 results. (In the latter case, semicolon is, or was at the time of writing this text , treated as ordinary string character, as if the url was: http://www.google.com/search?q=nemo

问题 What is the limit on QueryString / GET / URL parameters 回答1: There is no limit in theory. For HTTP URLs, the HTTP 1.1 specification states: The HTTP protocol does not place any a priori limit on the length of a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs. A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can

I'm trying to accept a query string of the form ?param[key1]=value1&param[key2]=value2 and convert it into a Dictionary in C# MVC 4. This is trivial to do in PHP, but I haven't been able to find any method of reproducing this in C#. I know I can take an array via ?param=value1&param=value2 but that leaves issues of ordering and isn't nearly as useful for my
