关于Attempt

用PHP面向对象的方式实现try和catch

像专业人士一样操作 🆗

使用方法

$response = attempt(fn() => $this->client->get('ninja'))
    ->catch(ConnectException::class)
    ->done(fn() => []); //done can be replaced with ()

安装

最低要求是PHP 7.2+和Composer。

使用以下命令安装

composer require transprime-research/attempt

其他使用方法

$response = Attempt::on(fn() => $this->client->get('ninja'))
    ->catch(AttemptTestException::class)(); // or ->done()

// Do something with Response

catch 方法接受一个异常对象

$response = Attempt::on(fn() => $this->client->get('ninja'))
    ->catch(\AttemptTestException())(); // or ->done()

// Do something with Response

设置默认响应

$response = Attempt::on(fn() => $this->client->get('ninja'))
    ->with(['abc'])
    ->catch(AttemptTestException::class)
    ->done(); // ['abc'] is returned if exception is caught  

// with default value
attempt(fn() => $this->execute())
    ->catch(AttemptTestException::class, 'It is done') //returns 'It is done'
    ->done();
    
// closure as default value
attempt(fn() => $this->execute())
    ->catch(AttemptTestException::class, fn() => 'It is done') //returns 'It is done'
    ->done();
    
// handle the resolved default value in done()
attempt(fn() => $this->execute())
    ->catch(AttemptTestException::class, fn() => 'error') //returns 'It is done'
    ->done(fn(Exception $ex, $severity) => logger($severity, $ex));

多个异常

$response = Attempt::on(fn() => $this->client->get('ninja'))
    ->catch(AttemptTestException::class, HttpResponseException::class)()

// Do something with Response

多个catch块

attempt(fn() => $this->execute())
    ->catch(NinjaException::class, 'Ninja error') //returns 'It is done')
    ->catch(AnotherExeption::class, 'Another error') //returns 'It is done'
    ->done(fn($ex) => logger()->error($ex));

使用捕获的异常响应做更多操作

$response = Attempt::on(fn() => $this->client->get('ninja'))
    ->catch(AttemptTestException::class, HttpResponseException::class)
    ->done(fn(\HttpResponseException $e) => logger()->error($e->getMessage()));

// Do something with Response

更多功能：将默认值的执行传递给可调用的类

// loading...
