如果你的代码中需要频繁使用try-catch包括代码，且异常处理方式都相同，记录日志并抛出一个友好的错误提示，那么可以使用下面的方式进行改进。
原代码：
try {
// Use Stripe's library to make requests...
} catch(\Stripe\Error\Card $e) {
// Since it's a decline, \Stripe\Error\Card will be caught
$body = $e->getJsonBody();
$err = $body['error'];
print('Status is:' . $e->getHttpStatus() . "\n");
print('Type is:' . $err['type'] . "\n");
print('Code is:' . $err['code'] . "\n");
// param is '' in this case
print('Param is:' . $err['param'] . "\n");
print('Message is:' . $err['message'] . "\n");
} catch (\Stripe\Error\RateLimit $e) {
// Too many requests made to the API too quickly
} catch (\Stripe\Error\InvalidRequest $e) {
// Invalid parameters were supplied to Stripe's API
} catch (\Stripe\Error\Authentication $e) {
// Authentication with Stripe's API failed
// (maybe you changed API keys recently)
} catch (\Stripe\Error\ApiConnection $e) {
// Network communication with Stripe failed
} catch (\Stripe\Error\Base $e) {
// Display a very generic error to the user, and maybe send
// yourself an email
} catch (Exception $e) {
// Something else happened, completely unrelated to Stripe
}
改进之后：
function stripeResponse($function) {
try {
// Use Stripe's library to make requests...
\Stripe\Stripe::setApiKey("my_key");
$function();
} catch(\Stripe\Error\Card $e) {
// Since it's a decline, \Stripe\Error\Card will be caught
} catch (\Stripe\Error\RateLimit $e) {
// Too many requests made to the API too quickly
} catch (\Stripe\Error\InvalidRequest $e) {
// Invalid parameters were supplied to Stripe's API
} catch (\Stripe\Error\Authentication $e) {
// Authentication with Stripe's API failed
// (maybe you changed API keys recently)
} catch (\Stripe\Error\ApiConnection $e) {
// Network communication with Stripe failed
} catch (\Stripe\Error\Base $e) {
// Display a very generic error to the user, and maybe send
// yourself an email
} catch (Exception $e) {
// Something else happened, completely unrelated to Stripe
}
}
return $this->stripeResponse(function() {
\Stripe\Charge::create([
"amount" => 100,
"currency" => "eur",
"source" => "token",
"description" => "Description"
]);
});
//如果你想传入外部参数：
$a = [];
return $this->stripeResponse(function() use ($a) {
\Stripe\Charge::create([
"amount" => 100,
"currency" => "eur",
"source" => "token",
"description" => "Description"
]);
});
//如果你想传入外部参数，同时还需要改变外部参数的值，可以使用引用&
$a = [];
return $this->stripeResponse(function() use (&$a) {
\Stripe\Charge::create([
"amount" => 100,
"currency" => "eur",
"source" => "token",
"description" => "Description"
]);
});
