Zencart外贸建站-调试

Zencart二次开发：　把Zencart程序转到另一服务器后就出现了如下问题：

问题描述：IE浏览器中为空白，Firefox浏览器出现“Content Encoding Error”　谷歌浏览器出现：Error 2 (net::ERR_FAILED): Unknown error.

在网上搜索了大堆的案例，但是很少有这种情况的，官方论坛上出现了两个但是没有给出解决方案，只有一步步的调试。

1.先参照网上大部分人提过的，开启错误提示：

在if (defined(‘STRICT_ERROR_REPORTING’) && STRICT_ERROR_REPORTING == true) {

前面加上：defined(‘STRICT_ERROR_REPORTING’,true);

结果：没有任何的反应，错误信息都没有输出

2.设个输入点(var_dump(‘test error’); exit; 在application_top.php中从上到下逐行测试

结果：在require(‘includes/autoload_func.php’);前后有变化，输入点放在此句前能够输出test error,放在后面就又变成和问题描述中一样，由此判断问题出自autoload_func.php文件

3.利用Zenstudio提供的ZendDebugger对autoload_func.php设置断点调试

并在if (DEBUG_AUTOLOAD === true) echo $debugOutput;上面加上var_dump(DEBUG_AUTOLOAD);var_dump($debugOutput);

进入调试模式，一步步的执行，输出信息如下：

string(80) “actionPoint=>40 include(‘includes/init_includes/init_db_config_read.php’); ”
bool(false)
string(47) “actionPoint=>50 $sniffer = new sniffer(); ”

输入这些之后就报错了，打开includes/auto_loaders/config.core.php文件发现是调用到

$autoLoadConfig[50][] = array(‘autoType’=>’init_script’,
‘loadFile’=> ‘init_gzip.php’);

时出的错。
4.上网搜索了一会发现，这是gzip是对ＰＨＰ文件进行加速用的，需要在php.ini中配置才行。

打开php.ini，添加下面语句即可为全站的php文件启用gzip加速：
output_buffering = Off
output_handler =
zlib.output_compression = On

重启后发现问题已解决
