為什么我的CodeIgniter庫沒有加載某些類

Question

我正在嘗試將Evernote SDK集成到我的CodeIgniter Web應用程序中，並且從庫中加載了某些類，而沒有加載其他類，：-SI無法理解原因。

我有一段簡單的代碼：

$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);

雖然正確創建了$userStoreTrans和$userStoreProt ， THttpClient Evernote SDK中的THttpClient和TBinaryProtocol類， $userStoreClient拋出了Class 'UserStoreClient' not found in .../home.php的Class 'UserStoreClient' not found in .../home.php

我不明白為什么可以識別某些類而不能識別某些類，我可以看到的主要區別是“ TClasses”位於evernote-sdk-php/lib/transport/*.php和evernote-sdk-php/lib/protocol/*.php和UserStoreClient有一個額外的文件夾evernote-sdk-php/lib/packages/UserStore/*.php

我將說明如何在我的CodeIgniter安裝中包括evernote-sdk-php：

這是我的CodeIgniter config / autoload.php

$autoload['libraries'] = array('database','session','form_validation','security','tank_auth','Evernote_bootstrap');

這是我的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類的主要目的是evernote require_once of evernote-sdk-php/lib/autoload.php的require_once of evernote-sdk-php/lib/autoload.php ，該類是使用-phpa Thrift生成器標志自動生成的，我只添加了一些日志記錄即可查看問題。

autoload.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，我登錄了該庫，看起來工作正常。 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'])); 和輸出： http : //pastebin.com/8w1MCKx9 ：

如您所見，UserStore類似乎比THttpClient或TBinaryProtocol加載得還好...關於此問題的任何想法？

我不知道它是否重要，但是我注意到在autoload.php上定義的$GLOBALS['THRIFT_ROOT']無法從CI控制器訪問。 可能我缺少有關CI體系結構的信息。

從我們最新的SDK更新開始，UserStoreClient（和其他SDK類）位於適當的名稱空間中。 假設您正在使用我們生成的代碼，是否已導入正在使用的類？ 例如

use EDAM\UserStore\UserStoreClient;
