问题 When to use RequestHandler.get_argument() , RequestHandler.get_query_argument() and RequestHandler.get_body_argument() ? What is the use-case for each of them? Also what does the request.body and request.argument do in these cases? Which are to be used in which scenarios? And, is there a request.query or something similar too? 回答1: Most HTTP requests store extra parameters (say, form values) in one of two places: the URL (in the form of a ?foo=bar&spam=eggs query string), or in the request

问题 Let's assume that I want to add a favicon on a dynamically generated page (specifically an ADF Faces page, but this is irrelevant). I can't modify a tag of my resulted html. So I try to add a http-header in servlet header. I want my header to be identical to html head element: <link rel="shortcut icon" href="http://foo.com/favicon.ico"> I'm adding it this way: httpResponse.addHeader("Link", "<http://foo.com/favicon.ico>; rel=\"shortcut icon\""); And in my browser I see this header in response

问题 I am building an app which consists of a menu and a webview. When the user is selecting menu items, the webview should load the respecting html file. So far so good. Now I am experiencing, that the webview is requesting the html each time I am pressing the menu item. I would like to only load the html once in a session, cause the html files wont change during a day. So first thing I did is to set the expires header correctly on the server side.

问题 Using PHP how can I accurately test that a remote website supports the "If-Modified-Since" HTTP header. From what I have read, if the remote file you GET has been modified since the date specified in the header request - it should return a 200 OK status. If it hasn't been modified, it should return a 304 Not Modified. Therefore my question is, what if the server doesn't support "If-Modified-Since" but still returns a 200 OK? There are a few tools out there that check if your website supports

问题 I am trying to workaround CORS restriction on a WebGL application. I have a Web Service which resolves URL and returns images. Since this web service is not CORS enabled, I can't use the returned images as textures. I was planning to: Write a PHP script to handle image requests Image requests would be sent through the query string as a url parameter The PHP Script will: Call the web service with the query string url Fetch the image response (web service returns a content-type:image response)

问题 I'm trying to develop a full PHP web browser that can handle cookies. I've created the following class: <?php class Browser { private $cookies = ''; private $response_cookies = ''; private $content = ''; /** * Cookie manager * @Description : To set or get cookies as Array or String */ public function set_cookies_json($cookies) { $cookies_json = json_decode($cookies, true); $cookies_array = array(); foreach ($cookies_json as $key => $value) { $cookies_array[] = $key .'='.$value; } $this-

问题 This is what I am trying to achieve with Angular : this.headers = ...; this.http.get(`${urlApi}`).subscribe(data => { // go to url with specific headers }, err => { console.log(err); }); When I get the response of a get request from my server, I want to redirect to an external url with specific headers, to be able communicate some information between two apps. There must be a way to do this. I know it's not possible using window.location.href . 回答1: From what I have learnt, this is a
