Question

我正在开发一个codeigniter项目，该项目需要将推送通知发送到ios设备。在导入eapn库时，我无法弄清楚从ios app项目导出的.pem文件的放置位置。而且我也无法弄清楚如何引用它的路径。

这是Pushnotification.php库

您可以将此密钥文件（.pem）放在项目的任何位置。但是将此文件放入/library文件夹的最佳方法是创建一个新文件夹keys

现在，在您的库文件中，您必须添加real path。

function __construct() {
    $this->keyCertFilePath = APPPATH.'library/keys/'.$this->_ci->config->item('PermissionFile','apn');

这是最好的方法，如果它不起作用，请告诉我。

Codeigniter APN.where将.pem文件放在php代码中
