http-headers

问题 I am using the following code to get the Client's Ip Address. But for all the headers, i am getting null value. And request.getRemoteAddr() returns IP address of the machine on which Tomcat server is running. So, what is the efficient way to get the IP address of the machine from which request is coming ? private static final String[] HEADERS_TO_TRY = { "X-Forwarded-For", "Proxy-Client-IP", "WL-Proxy-Client-IP", "HTTP_X_FORWARDED_FOR", "HTTP_X_FORWARDED", "HTTP_X_CLUSTER_CLIENT_IP", "HTTP

问题 I'm using k8 v1.7 and Python Client v2.0. My custom scheduler detects a pending pod and schedules it successfully. However, after assigning a pod to a node, it complains that the pod is already assigned to a node though it is just assigned by the scheduler itself. Is this something to be concerned? Or how can I fix this? Error Message create_namespaced_binding: (409) Reason: Conflict HTTP response headers: HTTPHeaderDict({'Date': 'Tue, 19 Jun 2018 16:14:57 GMT', 'Content-Length': '289',

问题 In Android, I am using Fuel, a Kotlin library, to fetch a JSON file. Right now, my code looks like this (url is a variable of type string): url.httpGet().responseJson { _, _, result -> when(result) { is Result.Failure -> { //Do Stuff } is Result.Success -> { //Do Stuff } } } However, I'd like to fetch an uncached version of the JSON file located at the url . I read this post: fetch(), how do you make a non-cached request? and it seems like I have to add the headers "pragma: no-cache" and

问题 I wanted to know how to check the server response of " If-Modified-Since " header sent by my browser. I am not sure how do I achieve it. Any help would be a great deal to me, Thanks. 回答1: Check the HTTP response code (e.g., using curl ). If the resource is not modified you get a 304 response, else, in the non-error case, a 200 . 来源： https://stackoverflow.com/questions/6661924/if-modified-since-header

问题 We are trying to make cross domain AJAX call via POST. If we directly try to access bbb.com from aaa.com it will ask for credentials. Only after giving credentials will we be able to access bbb.com . Now in the same way, when an AJAX call is made to a different domain, in this case bbb.com I'm receiving a 403 forbidden error. I tried adding the authorization header and now in the request header, I see the below headers but even after having authorization header I'm still having the issue.

问题 I'am trying to send via curl a rest request with a header consisting of authorization key and api key. Therefore I build following curl call: $api_key = 'abc'; $token = 'xyz'; $authorization = 'Authorization: Bearer ' . $token; $api = 'Api_key: ' . $api_key; curl_setopt($curl, CURLOPT_HTTPHEADER, array($authorization, $api)); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data); curl_setopt($curl,

问题 I'm working on "CDN" video delivery script. my problem is not all providers are included, therefor I need to check if the client can access the link, if not send him another one. i've tried with get_headers, but with get_headers only the server checks if it can access the link, not the user. $header = get_headers($VIDEO); preg_match('/\d{3}/', $header[0], $code); if($code[0] < 400){ header("Content-type: video/x-flv"); header("Location:" . $VIDEO . $dop); }else{ header("Content-type: video/x

问题 Can I do something like this? ob_start(); header("Content-Type: application/msword"); header("Content-Disposition: attachment; filename=".$title); header("Content-Length: ".$size); header("Content-Transfer-Encoding: binary"); readfile($path); ob_end_flush(); Currently I am getting the correctly named file to download, but the contents of the file is the html output from the php that contains the above code. I have verified the $path to be correct. Would a bad $size cause this to happen? I

问题 I've just moved a site to live and am getting a 406 Not Acceptable error when using jquery to make an ajax request to a php script. I don't get the error on my test server so I'm just trying to figure out the correct way to fix this. The AJAX request is as follows, and expects JSON response, while my php script is just echoing out with json_encode() . $.ajax({ type: "POST", contentType: "application/json", data: "{}", url: "server/php/progress.php", dataType: "json", EDIT: here's the crux of

问题 I’m finding that Nginx does not have features that I would consider basic, like send an Age header from proxy cache. In order to don’t let a browser store a cache which is max-age 60min, for 60min more if it’s already 59min old. I want to send an Age Header. (I prefer to use the same max-age for browsers and proxies) I came up with this solution, but I feel is a little bit ghetto, so I would like your opinions. I had to use LUA and then map{} because there was no other way I could make any
