我正在尝试将 Evernote SDK 集成到我的 CodeIgniter Web 应用程序中，并且库中的一些类已加载，而其他类则没有，:-SI 不明白为什么。
我有一段简单的代码：
$access_token = 'my validated access token ';
// Get User Store
$userStoreTrans;
try{
$userStoreTrans = new THttpClient(USER_STORE_HOST, USER_STORE_PORT, USER_STORE_URL, USER_STORE_PROTO);
}
catch(TTransportException $e)
{
print $e->errorCode.' Message:'.$e->parameter;
}
$userStoreProt = new TBinaryProtocol($userStoreTrans);
$userStoreClient = new UserStoreClient($userStoreProt, $userStoreProt);
在正确创建 and 时，来自 Evernote SDK 的$userStoreTransand类会抛出一个$userStoreProtTHttpClientTBinaryProtocol$userStoreClientClass 'UserStoreClient' not found in .../home.php
我不明白为什么有些类被识别而另一些类不被识别，我可以看到的主要区别是“TClasses”在evernote-sdk-php/lib/transport/*.phpandevernote-sdk-php/lib/protocol/*.php和 UserStoreClient 有一个额外的文件夹evernote-sdk-php/lib/packages/UserStore/*.php
我将解释如何将 evernote-sdk-php 包含到我的 CodeIgniter 安装中：
这是我的 CodeIgniter 配置/autoload.php
$autoload['libraries'] = array('database','session','form_validation','security','tank_auth','Evernote_bootstrap');
这是我的 Evernote_bootstrap.php 文件
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
define("EVERNOTE_LIBS", dirname(__FILE__) . DIRECTORY_SEPARATOR . "evernote-sdk-php/lib");
// add ourselves to include path
ini_set("include_path", ini_get("include_path") . ":" . EVERNOTE_LIBS);
require_once("evernote-sdk-php/lib/autoload.php");
require_once("evernote-oauth/functions.php");
class Evernote_Bootstrap
{
function __construct()
{
// log_message('debug','Evernote_Bootstrap');
}
}
?>
Evernote_Bootstrap 类的主要目的是require_once of evernote-sdk-php/lib/autoload.php，这个类是使用 -phpa Thrift 生成器标志自动生成的，我只添加一些日志来查看问题。
自动加载.php：

function scrapeClasses($filename) {
$fh = fopen($filename, "r");
while ($line = fgets($fh)) {
$matches = array();
if ( preg_match("/^\s*class\s+([^\s]+)/", $line, $matches)) {
if (count($matches) > 1)
$GLOBALS['THRIFT_AUTOLOAD'][strtolower($matches[1])] = $filename;
}
}
}
function findFiles($dir, $pattern, &$finds) {
if (! is_dir($dir))
return;
if (empty($pattern))
$pattern = "/^[^\.][^\.]?$/";
$files = scandir($dir);
if (!empty($files)) {
foreach ($files as $f) {
if ($f == "." || $f == "..")
continue;
if ( is_file($dir . DIRECTORY_SEPARATOR . $f) && preg_match($pattern, $f)) {
$finds[] = $dir . DIRECTORY_SEPARATOR . $f;
} else if ( is_dir($dir . DIRECTORY_SEPARATOR . $f) && substr($f, 0, 1) != ".") {
findFiles($dir . DIRECTORY_SEPARATOR . $f, $pattern, $finds);
}
}
}
}
function str_var_dump($object)
{
ob_start();
var_dump($object);
$dump = ob_get_clean();
return $dump;
}
// require Thrift core
require_once(dirname(__FILE__) . DIRECTORY_SEPARATOR . "Thrift.php");
if (! isset($GLOBALS['THRIFT_ROOT']))
$GLOBALS['THRIFT_ROOT'] = dirname(__FILE__);
log_message('debug','bootstrap autoload.php is executing');
// stuff for managing autoloading of classes
$GLOBALS['THRIFT_AUTOLOAD'] = array();
$GLOBALS['AUTOLOAD_HOOKS'] = array();
$THRIFT_AUTOLOAD =& $GLOBALS['THRIFT_AUTOLOAD'];
// only populate if not done so already
if (empty($GLOBALS['THRIFT_AUTOLOAD'])) {
//$allLibs = glob( dirname(__FILE__) . "/**/*.php"); // oh poor winblows users can't use glob recursively
$allLibs = array();
findFiles( dirname(__FILE__), "/\.php$/i", $allLibs);
log_message('debug',str_var_dump($allLibs));
if (!empty($allLibs)) {
foreach ($allLibs as $libFile) {
scrapeClasses($libFile);
}
log_message('debug','all scrapped classes: ' . str_var_dump($GLOBALS['THRIFT_AUTOLOAD']));
}
}else{
log_message('debug','$GLOBALS[THRIFT_AUTOLOAD] already defined');
}
// main autoloading
if (!function_exists('__autoload')) {
function __autoload($class) {
log_message('debug','__autoload');
global $THRIFT_AUTOLOAD;
$classl = strtolower($class);
if (isset($THRIFT_AUTOLOAD[$classl])) {
// log_message('debug','$THRIFT_AUTOLOAD[$classl] is set, do require_once');
//include_once $GLOBALS['THRIFT_ROOT'].'/packages/'.$THRIFT_AUTOLOAD[$classl];
require_once($THRIFT_AUTOLOAD[$classl]);
} else if (!empty($GLOBALS['AUTOLOAD_HOOKS'])) {
log_message('debug','$GLOBALS[AUTOLOAD_HOOKS]is no empty, lets foreach');
foreach ($GLOBALS['AUTOLOAD_HOOKS'] as $hook) {
// log_message('debug','iterate');
$hook($class);
}
} else {
log_message('debug','nothing to do');
}
}
}
然后我记录了那个库，似乎工作正常。您可以看到主要的重要日志：log_message('debug',str_var_dump($allLibs));和log_message('debug','all scrapped classes: ' . str_var_dump($GLOBALS['THRIFT_AUTOLOAD']));输出：http ://pastebin.com/8w1MCKx9 ：
正如你所看到的，UserStore 类似乎与 THttpClient 或 TBinaryProtocol 一样好加载......关于这个问题的任何想法？
我不知道这是否重要，但我注意到$GLOBALS['THRIFT_ROOT']在 autoload.php 上定义的，不能从 CI 控制器访问。可能我错过了关于 CI 架构的一些东西。
