php Exception.getMessage()总是不返回任何内容

Question

当我在php中捕获异常并尝试输出一些细节时,getMessage()总是不返回任何内容.如果我执行var_dump(),我会看到要显示的消息.我究竟做错了什么？

                try
                {
                    ...
                }
                catch (Exception $e)
                {
                    echo "<p>Exception: " . $e->getMessage() . "</p>"; 
                    return;
                }

如果我做var_dump($ e)我得到以下输出:

object(ETWSException)#735(10){["errorCode":protected] => int(401)["errorMessage":protected] => string(226)"HTTP/1.1 401未授权日期:2015年8月21日星期五18 :26:30 GMT服务器:Apache WWW-Authenticate:OAuth realm = https://etws.etrade.com/,oauth_problem=token_expired 内容长度:995内容类型:text/html; charset = utf-8"[" httpCode":protected] => NULL ["message":protected] => string(0)""["string":"异常":private] => string(0)""["code":protected] = > int(0)["file":protected] => [snip!]

我认为getMessage()应该显示errorMessage的内容.

嗯,我试过$ E-> getErrorMessage()和这显示预期的消息.搜索谷歌的php异常getErrorMessage似乎没有显示任何有用的东西(所有页面似乎只提到getMessage,而不是getErrorMessage).是什么赋予了？

电子贸易例外类是一团糟.它实现了自己的构造函数,并没有为标准设置正确的值Exception.它希望您用来$e->getErrorMessage()获取消息.
