问题 I am trying to subscribe to an ical feed through Yahoo Calendar using a URL in the following format: https://calendar.yahoo.com/subscribe?ics={__ICS_FEED_URL__}&name={__NAME__} . After accessing that URL, Yahoo presents me with a dialog box pre-populated with the URL to the feed and the name. After hitting "OK" a dialog box follows soon after with a 500 error.

问题 I gave an answer to following thread. but in the comment a user suggested that network admin can change the default port of http from 80 to something else. As for as I know if I open a page eg. http://www.example.com without port that means it is running on port 80. I just want to clarify that is it possible for network admin to change default port? 回答1: When using a browser, http://www.example.com will always try and connect to the server's TCP port 80, like it's port 443 for HTTPS

问题 To overcome a CORS (cross origin request sharing) problem I am facing with submitting a regular HTTP request, I need to submit a hidden form in Angular 4. I did that in HTML with no problem. However, I am not sure how to do that in Angular. Here is the code I have in the html of my component: <form form #f="ngForm" action="https://whatever.site.I_access" method="get"> <input type="hidden" name="scope" value="openid email"> <input type="hidden" name="response_type" value="id_token token">

问题 I know there are a lot of different comminucation protocals like: http, tcp, ssh, socks5, SMTP, POP, etc. I also know that to achieve a comminication, we need to connect localhost:localport to remotehost:remoteport . For example, if we google something, we would connect a random local port to www.google.com: 80 . If we ssh a remote host, we would connect a random local port to remotehost: 22 . My question is: Are communication protocol Half-duplex or Full-duplex ? I guess the answer is Half

问题 While I was trying my project on localhost it was working fine, using https://cors-anywhere.herokuapp.com/ since I got the CORS problem. But once I deployed the site on Netlify, it gave me the error 426 (Upgrade Required), with or without using https://cors-anywhere.herokuapp.com/. These are the messages that appear on my console: >Failed to load resource: the server responded with a status of 426 (Upgrade Required) >Error: Request failed with status code 426 at createError.js:16 at settle.js

问题 What HTTP response code should be returned when a POST request was not successful and a request body was correctly formatted? For successful POST request i am using 201 - Created, but there is no equivalent not created code. I am thinking either 400 - bad request but that would actually point user that a request is poorly formatted or 304 - not modified. 回答1: What HTTP response code should be returned when a POST request was not successful and a request body was correctly formatted?

问题 I want my origin to be able to see the User-Agent header .e.g: Gecko/20100101 Firefox/62.0 not Amazon CloudFront . In the Behaviors tab I can whitelist User-Agent header, so it's passed to the origin correctly, however now CloudFront caches content per User-Agent , meaning that user visiting the CloudFront endpoint from different browsers forces CloudFront to go to the origin. Is there any way to configure CloudFront to pass some headers to the origin, but not necessarily cache against them?

问题 What is the difference between the two headers below? Which one is preferred? X-Auth-Token : dadas123sad12 Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ== 回答1: Authorization is the primary header used by clients to authenticate against peers in HTTP as foreseen in RFC 7235. It is often linked to the Basic authentication scheme as per RFC 7617, but that is not a given. The Basic scheme allows clients to provide a username-password-pair separated by a colon ( : ) coded in Base64. It cannot be

问题 I'm setting up a REST-server in PHP and want to allow the client to use an endpoint with different methods like GET, POST, PUT, DELETE, ... But there is a problem when I try adding the function for the POST method: The application runs the function for GET if I try to access it with POST via Postman. I already tried to comment the GET function but if I do this, I get an error 405. // Just a testing function for POST $app->post('/users', function (Request $request, Response $response, array
