Preface
Recently, I encountered some cross-origin problems when I was working on the project, although I shared a lot of cross-origin problems online. However, it is still a bit confusing when I encounter it. After the project is launched, write an article to summarize it.

Previously, I thought that the PHPcURL simulation request also had cross-origin restrictions. If you have any questions about the sensitive data that requires permission access when designing an interface (for example, personal data that needs to be viewed after logon ). I will perform token detection. However, other common interfaces can be obtained directly, but only cross...

In this article, the Browser Security-same-origin policy and pseudo-URL domain mentioned the same-origin policy of the Browser, which mentioned that XMLHttpRequest strictly abides by the same-origin policy and cannot be requested from different sources. However, in practice, cross-origin resource reque
Talking about how the Koa2 framework uses CORS to complete cross-origin ajax requests.
There are many ways to implement cross-origin ajax requests. One of them is to use CORS, and the key to this method is to configure it on the server side.
This article only describes the basic configurations that can complete normal cross-origin ajax response (I will not perfor
Note: The following code should be tested in Firefox 3.5, chrome 3.0, and Safari 4. The implementation method of IE8 is different from that of other browsers.
Cross-origin requests, as the name implies, are resources in one site to access resources on another site with different domain names. This is common. For example, you can use the style label to load external style table files, use the IMG label to load external images, use the script label to

Same-origin policy
In client programming languages such as JavaScript and ActionScript, the same-source policy is a very important security concept, which has an important significance in ensuring data security. The same-origin policy specifies that scripts in different domains are isolated. scripts in one domain canno
The first thing to make clear is that the git operation revolves around 3 big steps (virtually all SCM)1. Fetching data from Git (git clone)2. Change the Code3. Transfer the changes back to Git (git push)These 3 steps involve two repository, one is the remote repository, and the other one is the local repository, and then the workspace. which1, 32 steps related to remote Server/remote repository/remote branch,2 related to local repository/local branch. git clone will copy a copy to your local, G

This article mainly introduces the reasons for cross-origin javascript and the solution sharing. it is very detailed and comprehensive. if you need it, you can refer to it.

Javascript cross-origin is one of the most common problems for web developers.

Cross-origin access on the browser side has always been a problem. Most R D personnel have a good attitude towards js, and the scars are lost. Therefore, it hurts from time to time when the problem occurs. I remember using iframe and script domain declaration a long time ago. yahoo js util solves the problem of second-level domain name cross-origin access.When the time passes through and is pulled back to
