前端代码:
<code><iframe src="Customer/login_to_spe" width="100%" height="1200px" scrolling="no" frameborder="0"> </iframe> </code>
后端代码:
<code>function login_to_spe(){ //省略了get url 代码 header("Location: $url"); } </code>
前端代码和后端代码都在同一个域名下,login_to_spe()获取的url是另一个域名下的
iframe引用的是同域名下的url,虽然这个url进行了跳转,但为什么还是被浏览器拦截了?
浏览器报的错误:Load denied by X-Frame-Options: https://xxxx.com/ does not permit cross-origin framing.
最后查出来的问题是:清了浏览器的缓存就不会报错了。。ORZ。。

请求数据步骤
发送请求--->浏览器接受响应--->判断是否是同域下
是的话,就把响应数据返回给请求点。不是的话就提醒禁止跨域请求。
现在可以在响应头中增加
<code>header("Access-Control-Allow-Origin: *"); //允许的域 header("Access-Control-Allow-Methods: POST, GET, OPTIONS"); //允许的方法 header("Access-Control-Allow-Headers: X-PINGOTHER"); //允许的自定义header</code>
告诉浏览器可以把响应值返回给跨域请求的点

1楼的评论,说这针对的不对
看提示Load denied by X-Frame-Options: https://xxxx.com/ does not permit cross-origin framing.
X-Frame-Options头就是用来告诉浏览器,本页面是否应该在frame显示本页面。
它的配置:
<code>DENY 这个页面不允许在frame中显示 SAMEORIGIN 只允许在本域的frame中显示 ALLOW-FROM uri 配置允许显示的域</code>
因此,只需要添加如下
<code>header("X-Frame-Options: ALLOW-FROM xxx你的域xxx");</code>

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
