How to enable the cross-origin function for laravel
Preface
This article describes how to enable the cross-origin function in laravel. We will share the content for your reference and learning. I will not talk about it here. Let's take a look at the details.
Cross-origin requests

In the other (8888) project, index. jsp is as follows: // because jsp is actually a servlet, jsp is used to represent servlet here.
In fact, the above is nothing more than clicking the ajax button on the jsonp page to obtain data on the other page.

Cross-origin Javascript knowledge
Summary of JS cross-origin knowledge:
Before the term "cross-origin" often appeared, we used it frequently. For example, if the img and src of website A point to an image address of website B, there is no doubt that this is normally displayed (regardless of anti-leech technology). Similarly, you can direct the src attribute of th
pages. By comparing ASP with many other technologies that can provide this dynamic, you gain an in-depth understanding of the development of the ASP, while understanding the development of Web applications, not limited to understanding simple dynamic Web sites.The origin of HTMLThe World Wide Web (Wide web,www) originated in the CERN laboratory in Switzerland. Tim Berners-lee and its development team spent a great deal of time studying the creation o

Note:1: The jQuery version must be later than version 1.2. Otherwise, cross-origin processing is not supported. 2. Only GET requests are supported. 2. The requested URL must return data as shown in the following example.
Advantages and disadvantages of this solution:Advantages: 1: better than using iframe to add the output parent. the XXX () solution is simple, efficient, and clear, and the frontend processing is more convenient. 2: It is much
resolution and generation (fast network transmission ).
JSONP (JSON with Padding) is a "usage mode" of JSON, which can be used to solve cross-Origin data access problems in mainstream browsers. Because of the same-origin policy, web pages located in server1.example.com cannot communicate with servers that are not in server1.example.com, And the

JavaScript code dynamically inserts the script tag, the browser accesses the URL in the src attribute. This will send the information in the query string to the server. In listing 1, username and reservation are passed as name-value pairs. In addition, the query string contains the output format of the request to the server and the name of the callback function (showItinerary ). After the script tag is loaded, the callback function is executed and the information returned from the service is pa
