从命令行界面或Web调用时PhantomJS挂起
从命令行界面或Web调用时PhantomJS挂起
提问于 2013-05-21 04:24:44
我正在尝试使用phantomJS来捕获网址的屏幕截图，但是当我调用phantomJS (从命令行或web应用程序)时，它挂起并看到永远不会执行"exit()“调用。我似乎找不到任何错误消息，并且它一直在运行，直到我杀死它。这是传递给phantomjs命令的JS文件：
var page = require('webpage').create();
var system = require('system');
var script_address = '';
var page_to_load = '';
var members_id = '';
var activities_id = '';
var folder_path = '';
if (system.args.length < 5)
{
console.log('Usage: phantom_activity_fax.js script_address page_to_load members_id activities_id folder_path');
console.log('#Args: '+system.args.length);
phantom.exit();
}//END IF SYSTEM.ARGS.LENGTH === 1
//ASSIGN OUR ARGUMENTS RECIEVED
script_address = system.args[0];
page_to_load = system.args[1];
members_id = system.args[2];
activities_id = system.args[3];
folder_path = system.args[4];
console.log(system.args[0]);
console.log(system.args[1]);
console.log(system.args[2]);
console.log(system.args[3]);
console.log(system.args[4]);
//OPEN OUR PAGE WITH THE VALUES PROVIDED
page.open(page_to_load, function () {
console.log("Entering Anonymous Function, Beginning RENDER:\n");
page.render(folder_path+members_id+'_'+activities_id+'.png');
phantom.exit();
});我看到值被推送到控制台，但之后它就挂起了:(我尝试了web检查器，但不知道在哪里执行__run()调用，当我将调试器-autorun=yes添加到调用中时，没有看到任何变化:(。
这是我在命令行挂起时(以root用户身份)获得的输出：

/var/www/wv-wellvibe2-test/uploads/images/faxes/这是我作为自己的用户运行它时得到的输出，但我在指定的文件夹(传真)中看不到图像文件：

[user@wv-wellvibe2 ~]$ 不幸的是，正如我所说的，该命令已完成，但没有在faxes文件夹中保存.png。下面是该文件夹的权限：
[root@wv-wellvibe2 faxes]# ls -la

(这里请求的是调用Phantom JS流程的PHP脚本)
header("Date: " . date('Y-m-d H:i:s'));
//GET THE SMARTY CONFIG
include_once $_SERVER['DOCUMENT_ROOT'] . "/smarty/configs/config.php";
//VARS USED LATER
$process_script = $_SERVER['DOCUMENT_ROOT'] . '/javascripts/phantom_activity_fax.js';
$page_to_load = 'https://' . $_SERVER['HTTP_HOST'] . '/manual_scripts/phantom_js_test_page.php';
$members_id = $_SESSION['members_id'];
$activities_id = 0;
$folder_path = $_SERVER['DOCUMENT_ROOT'] . 'uploads/images/faxes/';
$system_response = '';
$call = "phantomjs --remote-debugger-port=65534 --remote-debugger-autorun=yes " . $process_script . " " . $page_to_load . " " . $members_id . " " . $activities_id . " " . $folder_path;
echo 'CallingSystemWith: ' . $call . '<br />';
try
{
$system_response = system($call);
echo '<br />SystemResponse: ' . $system_response . '<hr />';
} catch (Exception $exc) {
echo $exc->getTraceAsString();
}//END TRY / CATCH(它告诉PhantomJS“抓取”的页面是一个简单的PHP脚本，它输出$_SESSION和$_REQUEST的print_r() )

使用：
$phantomjs --debug=true rasterize.js http://... test.pdf在rasterize.js中，在ressource上添加超时，这是我的问题：
page.settings.resourceTimeout = 10000; // Avoid freeze!!!页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
