PHP试图让非对象的属性 [英] PHP Trying to get property of non-object

问题描述

我运行APNS PHP脚本，它的工作正常，但一个文件抛出PHP错误，我想知道我应该怎么解决它。

I'm running an APNS PHP script and it's working fine but one file throws PHP errors and I want to know how I should fix it.

下面的错误弹出：

/usr/bin/php -f /usr/share/nginx/www/processFeedback.php

<br/>Started processing FeedbackPHP Notice:  Trying to get property of non-object in /usr/share/nginx/www/processFeedback.php on line 46
PHP Warning:  stream_socket_client(): unable to connect to  (Failed to parse address "") in /usr/share/nginx/www/classes/Apns.php on line 66
PHP Notice:  Undefined variable: errstrn in /usr/share/nginx/www/classes/Apns.php on line 69

46号线：

$apns = new apns($server->ServerUrl, $certificatePath, $certificate->Passphrase);

66号线：

$this->stream = stream_socket_client($this->server, $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);

69号线：

throw new Exception("<br/>Failed to connect $err $errstrn");

我不是一个PHP的专家，所以我错过了什么？

I'm not a PHP expert so what am I missing?

推荐答案

就在堆栈跟踪看准了这一点：

Just spotted this in the stack trace:

#1 /usr/share/nginx/www/processFeedback.php(46): Apns->__construct(NULL, 'certificates/ck...', 'passwd') .

这清楚地表明，$服务器是NULL。你有什么期望SERVERURL是？也许你可以只在相关的行输入一个字符串，像这样：

This clearly shows that $server is NULL. What do you expect the ServerUrl to be? Maybe you could just enter that as a string in the line in question, like so:

$apns = new apns('myServerUrl', $certificatePath, $certificate->Passphrase)
