Laravel5.2 How to jump to 404 when accessing a non-existent route? How to configure LNMP environment?
Theoretically, if you turn off debug
, the online environment will automatically get 404
.
Do you want to "jump to page 404" or "show page 404"? If you want to jump, please configure app/Exceptions/handler.php and return a Redirect response when NotFoundException is thrown.
1. If you just want to throw a 404 error, the debug switch can satisfy you;
2. If you want to handle exceptions or customize exceptions, please refer to the following;
The Handler.php
file in the Exceptions
directory under the app
in the laravel project root directory; we can customize exceptions
and handle exceptions
here;
The most common one is
ModelNotFoundException
Here is a Demo:
route:
vikin.cc/article/8
Handler file:
//处理Http响应异常 public function render($request, Exception $e) { switch($e){ //使用类型运算符 instanceof 判断异常(实例)是否为 ModelNotFoundException case ($e instanceof ModelNotFoundException): //进行异常处理 return $this->renderException($e); break; default: return parent::render($request, $e); } } //处理异常 protected function renderException($e) { switch ($e){ case ($e instanceof ModelNotFoundException): //自定义处理异常,此处我们返回一个404页面 return view('errors.404'); break; default: //如果异常非ModelNotFoundException,我们返回laravel默认的错误页面 return (new SymfonyDisplayer(config('app.debug'))) ->createResponse($e); } }
Through the above cases, you can easily handle exceptions and give users a friendly prompt!

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
