Example explanation of using try catch in laravel5
This article mainly introduces the knowledge about using try catch in laravel5. Friends who need it can refer to it
Using the following code in laravel5 does not catch the exception
try{
var_dump($val);
}catch (Exception $e){
var_dump($e);
echo $e->getMessage();
}The Laravel 5 era controller is forced to be placed under the sub-namespace, so that the Exception class under the root namespace cannot be called directly. Laravel 4 controllers can be used directly under the namespace. After PHP 5.3, all classes will be in the namespace by default. If not declared, they will be in the top-level namespace by default.
So to use try catch syntax, either use \Exception at the beginning of the code, or use catch (\Exception $e). So the correct way to use it is
try{
var_dump($val);
}catch (\Exception $e){
var_dump($e);<br><br>echo $e->getMessage();
<br>
}ps: try catch problem in Laravel 5: Exception cannot be detected
In a recent project, I tried to use try catch and found that There has been no success
try{
var_dump($val);
}catch (Exception $e){
var_dump($e)；
}In php, this code should print the value of $e. However, this is not the case in Laravel 5. This is because Laravel 5 enforces the use of the PSR standard and the correct namespace must be used.
So to use try catch syntax, either use \Exception at the beginning of the code, or use catch (\Exception $e). So the correct way to use it is
try{
var_dump($val);
}catch (\Exception $e){
var_dump($e)；
}Summary

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1.
