Continued ： Pagoda installation hyperf

As mentioned above, how to install in the pagoda hyperf frame , The rest of the operation and maintenance panels are not bad , I won't go back to .

The tools used here phpstorm

tips： If you have laravel perhaps thinkphp5.1(6) Words , You will find that the general operation is consistent , It's easy to get started , Finally, be diligent in reading documents , Read the document in time if you don't understand .

One 、 Plug in installation

start-up hyperf After a successful visit , You also need to install two plug-ins

PHP Annotation
Swoole IDE Helper

Let's talk about the function ：

PHP Annotation The purpose of this is to achieve php Annotation definition in , At the same time hyperf There is also a section about the role of routing annotations , Details move : annotation annotation          annotation

After installing the plug-in , You can use

 domain name :9501/ modular / controller / Method   

  This way to access

Such as this ：

​

​

If the route annotation is not installed , Destined to be only config/routes.php The short route name is defined in the route file , Visit again .

Such as this ：

​

 ​

​

Swoole IDE Helper： Used for compiling swoole A plug-in that prompts code when .

Two 、 The basic document explains ：

​

Please configure according to the file directory mysql Connection or other information , If configured env Invalid configuration , Please go config/autoload/ Search for databases.php To configure mysql Information

3、 ... and 、 Code display

use Hyperf\DbConnection\Model\Model as BaseModel;

// Introduce soft deletion 
use Hyperf\Database\Model\SoftDeletes;

class Admins extends BaseModel
{
    use SoftDeletes;
}

because hyperf Inside did json Handle , So in return Return the normal array when , No need to be like tp perhaps laravel Same first json Again return 

Effect display ：

add to ：

modify ：

Delete ：

Inquire about ：

More chained queries and aggregate functions 、 Self increment and self decrement of fields 、 to update json Fields, etc

Please move to the model chapter ： Model

Four 、 close debug

hyperf The default creation time field and update time field are created_at  and updated_at , Pay attention to this point , If cli When an error is reported, remember to create these two fields ; If you don't want hyperf Take over these two fields , You need to set public $timestamps = false;

  as follows ：
