问题 How does Google Chrome's ADVANCED REST CLIENT plugin make cross domain POST requests? I thought maybe something with CORS but I don't see "Access-Control-Allow-Origin" in any response. This is a link to the plugin: https://chrome.google.com/webstore/detail/hgmloofddffdnphfgcellkdfbfbjeloo/related?hl=en-US 回答1: Short answer : Extensions are different from normal web pages. They can ask for extra permissions during the course of installation. (slightly) Long answer : The main requirement of

Angular 2 - No 'Access-Control-Allow-Origin' header is present on the requested resource

问题 When trying to make API Calls from my Angular 2 App to my API, I get the following error: XMLHttpRequest cannot load http://localhost/myAPI/public/api/v1/auth/login. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 422. I've been checking every single question on the web and anything releated to CORS, nothing solved my problem! My Laravel API running on port 80.

Disable cross domain web security in Firefox

问题 In Firefox, how do I do the equivalent of --disable-web-security in Chrome. This has been posted a lot, but never a true answer. Most are links to add-ons (some of which don't work in the latest Firefox or don't work at all) and "you just need to enable support on the server". This is temporary to test. I know the security implications. I can't turn on CORS on the server and I especially would never be able to allow localhost or similar. A flag, or setting, or something would be a lot better

springboot基于CORS处理跨域问题

由 天涯浪子 提交于 2020-01-08 01:46:05
1. 为什么有跨域问题 跨域不一定都会有跨域问题。 因为跨域问题是浏览器对于ajax请求的一种安全限制： 一个页面发起的ajax请求，只能是与当前页域名相同的路径 ，这能有效的阻止跨站攻击。 因此： 跨域问题 是针对ajax的一种限制 。 但是这却给我们的开发带来了不便，而且在实际生产环境中，肯定会有很多台服务器之间交互，地址和端口都可能不同，怎么办？ 2. 解决跨域问题的方案 目前比较常用的跨域解决方案有3种： Jsonp 最早的解决方案，利用script标签可以跨域的原理实现。 限制： 需要服务的支持 只能发起GET请求 nginx反向代理 思路是：利用nginx把跨域反向代理为不跨域，支持各种请求方式 缺点：需要在nginx进行额外配置，语义不清晰 CORS 规范化的跨域请求解决方案，安全可靠。 优势： 在服务端进行控制是否允许跨域，可自定义规则 支持各种请求方式 缺点： 会产生额外的请求 3. cors解决跨域 3.1 什么是cors CORS是一个W3C标准，全称是"跨域资源共享"（Cross-origin resource sharing）。 它允许浏览器向跨源服务器，发出 XMLHttpRequest 请求，从而克服了AJAX只能 同源 使用的限制。 CORS需要浏览器和服务器同时支持。目前，所有浏览器都支持该功能，IE浏览器不能低于IE10。 浏览器端： 目前

启用CORS实现Ajax跨域请求

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 应用场景：想从a.com请求b.com上的资源，由于同源策略不允许请求。 解决办法：在请求的php文件中加入 header("Access-Control-Allow-Origin: http://b.com"); 这种比较安全，如果请求来源比较多，可以这么设置 header("Access-Control-Allow-Origin: *"); 如果使用Nginx，需要配置让其支持ajax跨越请求， 参考网址 location / { if ($request_method = 'OPTIONS') { add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS'; # # Custom headers and headers various browsers *should* be OK with but aren't # add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since

Why isn't my nginx web server handling ttf fonts?

由 安稳与你 提交于 2020-01-07 08:46:29
问题 I've been researching this issue where a specific font file isn't rendered on remote sites because of CORS restrictions. So far I have been able to identify that requests for that url are responding with access-control-allow-origin, but nginx is rejecting requests for that font when made remotely. I am using laravel and the laravel-cors plugin from spatie, but I wouldn't think that would return header information for a style sheet or font not rendered from laravel routes. Does anyone know why

Understanding CORS on UPnP/DLNA browsing

问题 I've been playing around with home-grown UPNP/DLNA Browsing. What I manage to do is a shell script based approach using curl to query the Server and xsl processing to make html pages out of the answers. Next I thought I could build all this into javascript/kind of interactive browser page. But now I hit the CORS issue as the requests are preflighted by the browser (they are not preflighted when using curl and the server speaks no CORS, just UPnP). Some simplest code trying to get the root of
