如何修正twilio-php在查找坏数字上的未明异常？

Question

我不知道抛出异常是怎么回事.

当我在查找中输入一个不好的数字时，我会得到以下信息：

致命错误:在/home/jimbursch/includes/twilio-php/Services/Twilio.php:297堆栈跟踪中未找到“未找到所请求的资源/PhoneNumbers/310-69-5340”消息的未命名异常“Services_Twilio_RestException”：#0 /home/jimbursch/includes/twilio-php/Services/Twilio.php(265)：Base_Services_Twilio->_processResponse( /home/jimbursch/includes/twilio-php/Services/Twilio.php(236)：Base_Services_Twilio->_makeIdempotentRequest(Array，) #1 /home/jimbursch/includes/twilio-php/Services/Twilio.php(236)：Base_Services_Twilio->_makeIdempotentRequest(Array，‘/v1/PhoneNumber.’，1) #2 /home/jimbursch/includes/twilio-php/Services/Twilio/InstanceResource.php(79)：Base_Services_Twilio->retrieveData('/v1/PhoneNumber...') #3 /home/jimbursch/includes/site_functions.php(655)：Services_Twilio_InstanceResource->__get('phone_number') #4 /home/jimbursch/include/admin/misc.php(43)：lookupPhone('310-69-5340')

这就是我认为它正在发生的地方：

private function _processResponse($response)
{
    list($status, $headers, $body) = $response;
    if ($status === 204) {
        return true;
    }
    $decoded = json_decode($body);
    if ($decoded === null) {
        throw new Services_Twilio_RestException(
            $status,
            'Could not decode response body as JSON. ' .
            'This likely indicates a 500 server error'
        );
    }
    if (200 <= $status && $status < 300) {
        $this->last_response = $decoded;
        return $decoded;
    }
    throw new Services_Twilio_RestException(
        $status,
        isset($decoded->message) ? $decoded->message : '',
        isset($decoded->code) ? $decoded->code : null,
        isset($decoded->more_info) ? $decoded->more_info : null
    );
}

你必须catch这个例外。

正确的是，当发生错误时，Twilio SDK抛出一个异常。

你必须做如下事情：

<?php
...

try {
    //Your Twilio code you'd like to execute
} catch( Services_Twilio_RestException $e ) {
    echo $e->getMessage(); // Or maybe log it
    // Handle the fact that "The requested resource /PhoneNumbers/310-69-5340 was not found"
}

通过捕获错误消息，您可以避免Fatal error，并且您的脚本可以继续工作，从而允许您注册操作失败(或者报告了其他有用的信息)。
