Magento 如何显示完整的错误消息而不是截断一个

Question

任何人都知道如何让 Magento 显示完整的错误消息，而不是用...截断它

例子:

Warning: include() [function.include]: Filename cannot be empty  in /home/kevinmag/public_html/app/code/core/Mage/Core/Block/Template.php on line 241

0 /home/kevinmag/public_html/app/code/core/Mage/Core/Block/Template.php(241): mageCoreErrorHandler(2, 'include() [fetchView('frontend/base/d...')

我想知道 [fetchView('frontend/base/d...') 它与 ...

不要责怪 Magento，这都是 PHP 的错 :) Exception::getTraceAsString native 方法削减了回溯输出，似乎没有正常的方法来处理它。

我必须工作的唯一解决方案是下一个:

我添加了一个功能，我从善良的先生 那里得到的Steve ( How can I get the full string of PHP’s getTraceAsString() ) 到 app\code\core\Mage\Core\functions.php:

function getExceptionTraceAsString($exception) {
    $rtn = "";
    $count = 0;
    foreach ($exception->getTrace() as $frame) {
        $args = "";
        if (isset($frame['args'])) {
            $args = array();
            foreach ($frame['args'] as $arg) {
                if (is_string($arg)) {
                    $args[] = "'" . $arg . "'";
                } elseif (is_array($arg)) {
                    $args[] = "Array";
                } elseif (is_null($arg)) {
                    $args[] = 'NULL';
                } elseif (is_bool($arg)) {
                    $args[] = ($arg) ? "true" : "false";
                } elseif (is_object($arg)) {
                    $args[] = get_class($arg);
                } elseif (is_resource($arg)) {
                    $args[] = get_resource_type($arg);
                } else {
                    $args[] = $arg;
                }
            }
            $args = join(", ", $args);
        }
        $rtn .= sprintf( "#%s %s(%s): %s%s(%s)\n",
            $count,
            $frame['file'],
            $frame['line'],
            isset($frame['class']) ? $frame['class'] . '->' : '',
            $frame['function'],
            $args );
        $count++;
    }
    return $rtn;
}

我修改了 Mage.php 文件(printException 方法) - 而不是 $e->getTraceAsString()我已插入 getExceptionTraceAsString($e) - 注意有两种外观: Debug模式打开和关闭。

为了演示结果，这里是两个回溯的示例 - 没有修复，并且有相应的修复。

更新 :上述逻辑只修改了错误/报告输出；要将此逻辑添加到异常日志中，您还需要修改 Mage::logException 方法 - 更改

self::log("\n" . $e->__toString(), Zend_Log::ERR, $file);

和

self::log("\n" . $e->getMessage() . getExceptionTraceAsString($e), Zend_Log::ERR, $file);

希望能帮助到你!
