Why is CORS without credentials forbidden?

由 混江龙づ霸主 提交于 2019-12-29 08:03:14
问题 I'm trying to understand why cross domain requests without credentials is not allowed (by default, without setting up server to return Access-Control-Allow-Origin header). In case of request with credentials all is pretty straightforward - one can fulfill some malicious actions on your behalf on other sites, for example on facebook, if you have logged in on it. For example this request: xhr = new XMLHttpRequest(); xhr.open('GET', 'http://www.google.com'); xhr.send(); produce an error ( I

Dealing with incremental server response in AJAX (in JavaScript)

由 烈酒焚心 提交于 2019-12-29 07:38:09
问题 I have AJAX app which updates page based on server response. The command that AJAX server response is based on takes long time to generate full response, but it sends partial information as soon as it is calculated. This partial response / partial info is send in "burst", and time and size of each burst is unpredictable. CGI script (in Perl) that streams command output to web browser (to AJAX request) has autoflush turned on. The server response is based on output of external command. While

VBA XMLHTTP clear authentication?

由 不问归期 提交于 2019-12-29 06:30:14
问题 I am writing a set of VBA macros in which it uses the XMLHTTP object to send asynchronous requests to a server. I am sending Basic Authentication with: XMLHttpReq.setRequestHeader "Authorization","Basic " & Base64EncodedUserPass This works great the first time. But if the user changes their userid/password, even if the code creates a brand new XMLHttpReq object and sets this header to the new information, it logs in to the server as the first user, presumably from cached credentials. How can

How to send Json object (or string data) from Javascript xmlhttprequest to MVC Controller

由 假如想象 提交于 2019-12-29 05:46:27
问题 I created a web application in ASP.NET MVC and trying to call a controller through Javascript AJAX. In Jquery we can send a json object which MVC Model Binder automatically tries to create a .NET object and pass in the controller as an argument. However I am using a web workers in which jquery cannot be used. So I am making the AJAX call through the vanilla xmlhttprequest object. Is there a a way to send the Json object through this method? I used the xmlhttprequest's send method but the

Ajax简介 Ajax 的全称是 Asynchronous JavaScript and XML（异步的 JavaScript 和 XML），是一种用于创建动态网页的技术。 Ajax 是一种使用现有标准的新方法，通过与服务器进行少量的数据交换，Ajax 可以使网页实现异步更新，这意味着可以在不重新加载整个网页的情况下，对网页的某部分进行更新。 Ajax的优缺点 Ajax 的优点： 最大的优点是页面无刷新更新，用户的体验非常好 使用异步方式与服务器通信，具有更迅速的响应能力 可以将一些服务器工作转移到客户端，利用客户端资源来处理，减轻服务器和带宽的压力，节约空间和带宽租用成本 技术标准化，并被浏览器广泛支持，不需要下载插件或者小程序 Ajax 的缺点： Ajax 不支持浏览器 back 返回按钮 有安全问题，Ajax 暴露了与服务器交互的细节 对搜索引擎不友好 破坏了程序的异常机制 不容易调试 Ajax工作原理 在客户端（如浏览器）和服务器之间加了一个中间层：Ajax 引擎。由 Ajax 引擎独立向服务器请求数据，前端获取到 Ajax 返回的数据后，可以使用新数据来更新页面、或进行其它操作，使用户请求和服务器响应异步化，从而保证了在不刷新页面的前提下可以局部更新网页内容。 使用new XMLHttpRequest()命令来创建一个Ajax实例对象。 XMLHttpRequest类
