Here is how I have configured base url in react app. App.js let BASE_URL = '' let WS_BASE_URL = '' let

问题 I'm trying to fetch html file located at url https://sub.app.test/html from https://app.test using no-cors mode but the response is blocked by CORB (cross-origin read blocking). fetch('https://sub.app.test/html', { mode: 'no-cors'}) Why? 回答1: Even though no-cors mode is used (so the response doesn't need to have Access-Control-Allow-Origin to be allowed) the request is blocked by CORB because an html content is considered a data resource (it may contain sensitive data).

问题 I have setup FineUploader on a site and I included a check box that allows users to upload files using HTTPS if the want to. Unfortunately if the user accesses the site using http and then tries to use ssl it errors out, I assume because of CORS issues. I assume it is a CORS issue because if I access the site using https and try to upload using ssl it works fine. I found some documentation about enabling CORS support, but it appears that you either need to make it so only CORS requests will

问题 I'm having trouble accessing my server even with the npm cors package installed. import Express from 'express'; import compression from 'compression'; import bodyParser from 'body-parser'; import mongoose from 'mongoose'; import cors from 'cors'; /********************** SERVER CONFIG *********************/ import serverConfig from './config'; import auth from './routes/v1/auth.routes' // Initialize Express const app = new Express(); // DB Setup mongoose.connect(serverConfig.mongoUrl, error =>

问题 The Azure CORS settings doesn't seem to work at all unless I specify * any and all requests will return "has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status." I've added my CORS http + https variants of both my production + dev environment frontend. I have also added them in the web.config. <add name="Access-Control-Allow-Origin" value="https://LINK"/> <add name="Access-Control-Allow-Origin" value="https://LINK/"/>

问题 The preflight is not supposed to happen for simple requests as per the documentation: https://developer.mozilla.org/en/docs/Web/HTTP/Access_control_CORS). This is indeed the case if I don't put the additional "Authorization" header in the request: "Content-Type": "application/x-www-form-urlencoded", "Authorization": "Basic _base64_string_" Without "Authorization" header: :authority:www.target.com :method:POST //<----------------This is correct :path:/oauth2/access_token?client_id=xxx-xxx
