PHP-在同一try-catch中包装变量块 [英] PHP - Wrap a variable block in the same try-catch

问题描述

在我的PHP项目中，我使用Guzzle发出许多不同的API请求。为了处理所有异常，每个API调用都包装在try-catch块中。示例：

in my PHP project, I use Guzzle to make a lot of different API requests. In order to handle all exception, each API call is wrapped into a try-catch block. An example:

        try {
            $res = $client->get($url, [
                'headers' => [
                    'Authorization' => "bearer " . $jwt,
                ]
            ]);
        } catch (ClientException $clientException) {
            // Do stuff
        } catch (ConnectException $connectException) {
            // Do stuff
        }catch (RequestException $requestException){
            // Do stuff
        }

对于每个请求，exceptiuon处理是相同的，但是实际的执行块相差很多，并且不能简单地由一系列选项来描述。

For each request, the exceptiuon handling is the same but the actual execution block differs a lot and can not be simply described by an array of options.

有没有一种方法可以创建功能/类将定制执行块包装到相同的try-catch处理中？

Is there a way to create a function/class able to wrap a custom execution block into the same try-catch handling?

我想到的唯一选择是使用带有函数的接口每个孩子扩展的execution（）和具有try-catch块并仅调用 run（）在执行块中> $ this-> execution（）。可以，但是我发现为每个仅在项目的一点使用的不同API调用创建一个全新的类太冗长。

The only options I came up with is to use an interface with a function execution() that is extended by each child and a function run() that has the try-catch blocks and simply calls $this->execution() inside the execution block. It would work, but I found too verbose the creation of a whole new class for each different API call that is only used in one point of my project.

更好/更少冗长的解决方案，以避免代码重复执行相同的异常处理？

Is there a better/less verbose solution to avoid code repetition of the same exception handling?

推荐答案

传递可调用对象，可以是匿名函数，常规函数或类方法：

Pass a callable, which can be an anonymous function, a regular function, or a class method:

function executeGuzzle(callable $fun) {
    try {
        return $fun();
    } catch (ClientException $clientException) {
        // Do stuff
    } catch (ConnectException $connectException) {
        // Do stuff
    } catch (RequestException $requestException) {
        // Do stuff
    }
}

$res = executeGuzzle(function () use ($client) {
    return $client->get(...);
});
