http-headers

问题 Our server returns a custom 'X-Execution-Time' HTTP response header that returns in miliseconds the time between the server getting a request and our code returning a page, ie how long our code takes to run. I'm using JMeter to do some testing & I'd like to be able to report on this number of over time. I've setup this regular expression extractor: X-Execution-Time:\s(\d+) but I don't know how to get JMeter to report on this number per request so i can get a trend over time 回答1: This isn't

问题 In internet, I see only add parameter to HTTP request like below. this.headers.append('Content-Type', 'application/json'); this.headers.append('Accept', 'application/json'); this.headers.append('Access-Control-Allow-Credentials', 'true'); I cannot find how can I get HTTP request header params in Angular 4. 回答1: The Headers class also has a get(name: string) method, which returns a string, as well as other helpful methods for inspecting the headers. From the Angular docs: https://angular.io

问题 I'm trying to send an image file(that resides locally) from my react single page frontend app to my flask backend. Some of the things I have tried out but not limited to are capturing my content type and indicating the encType on the front end. Although, the post requests indicates that it was successful. However, when I log the requests.files, request.form, request.values, I get no data input. Obviously, there's something I'm missing out and could really use any help I could get from anyone.

问题 Does the HTTP protocol allow a 302 request header to be modified so some parameters can be set and passed to the url receiving the request? 回答1: 302 is a response code, not a request header. The client will resolve the redirect by doing a new request for the new URL, so your client may add whatever headers it want to that new request. A server wanting some data be sent along to the new URL should do so by appending it to the URL as querystring variables, for example: http://example.com/new

问题 I have developed a solution that relies on an AJAX call to retrieve information and update the client page every 10 seconds. This is working fine, but I am concerned at the scalability of the code, given the number and length of headers being passed from client to server and back again. I have removed a number of redundant headers on the server side, mostly ASP.NET-related, and now I'm attempting to cut down on the headers coming from the client. The browser used by my company is IE (version

问题 I try to get the tags working in an express/node.js environment but somehow they always get blocked by the content security policy. I already tried using multiple node-modules like express-csp-header or csp-header but none of them did the trick. So I went back to 'normal' declaration. This is at the top of my server.ts script: app.use((req: any, res: any, next: any) => { res.set({ "Access-Control-Allow-Origin": "*", "Access-Control-Allow-Headers": "Origin, X-Requested-With, Content-Type,

问题 For now it looks like this func cacheHandler(h http.Handler) http.Handler { return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { w.Header().Set("Cache-Control", "max-age=1800") h.ServeHTTP(w, r) }) } http.Handle("/", cacheHandler(http.FileServer(http.Dir("./template/index")))) http.HandleFunc("/json", sendJSONHandler) http.HandleFunc("/contact", contactHandler) http.Handle("/static/", http.StripPrefix("/static/", cacheHandler(http.FileServer(http.Dir("./template/static")))))

问题 I need to integrate a RESTful API called SMMRY into my Android App. This API does automatic text summary of an URL or block of text that is sent to it. I am using Retrofit 2.1.0 as networking library. I have managed to put URL text summarization working perfectly, so when I pass the URL then it does the text summary and provides me back. But I am unable to correctly implement the POST request by sending the appropriate parameters (which include headers, etc), so that it does the summary of

问题 I'm trying to deliver a CSV file through an action. The mime-type in the response still shows as text/html. Can someone help? Thanks //$this->setLayout(false); //$this->getUser()->shutdown(); //sfConfig::set('sf_web_debug', false); $response = $this->getContext()->getResponse(); $response = $this->getResponse(); $response->clearHttpHeaders(); $response->setHttpheader('Pragma: public', true); $response->addCacheControlHttpHeader('Cache-Control', 'must-revalidate'); $response->setContentType(

问题 I have many many small images that are displayed on a user's profile and the loading of this page is horrible. The best solution is to sprite them all, but sadly I have too many images for that and only a few hundred are used per profile. So, I'm trying to get the second best solution. What headers should I send? ETag? Expires? Cache-Control? Right now I have: http://metaward.com/media/award/ofwjh3.png Last-Modified Sat, 11 Jul 2009 22:37:49 GMT Cache-Control max-age=2592000 Expires Tue, 29
