PhantomJS 非cli模式下Could not connect to display 错误

解决问题的是前人的提问

https://github.com/ariya/phantomjs/issues/14061

## 最后一层的哥们 ## 为 phantomjs 添加参数 <span style="\"font-family:" "helvetica="" neue",="" helvetica,="" arial,="" sans-serif;="" font-size:="" 22px;\"="">QT_QPA_PLATFORM=offscreen</span> 然后就成功了

## sudo -u www-data QT_QPA_PLATFORM=offscreenphantomjs

## 运行时为文件添加环境

## #!/bin/sh

## LD_LIBRARY_PATH=\"/usr/lib/phantomjs:$LD_LIBRARY_PATH\"

## export LD_LIBRARY_PATH

## export QT_QPA_PLATFORM=offscreen

## exec \"/usr/lib/phantomjs/phantomjs\" \"$@\"

## 就此解决cli模式能顺利运行，http就崩溃的问题 ## 说了这么多还没说遇到的问题。。。 ## 这是我在git上提的问题，直接搬过来 ## [https://github.com/jonnnnyw/php-phantomjs/issues/167](\"https://github.com/jonnnnyw/php-phantomjs/issues/167\") > ## I run it under php cli mode successflu.

## <?php
require \'vendor/autoload.php\';

## 
use JonnyW\\PhantomJs\\Client;

## 
$client = Client::getInstance();
$client->getEngine()->setPath(\'/usr/lib/phantomjs/phantomjs\');
//$client->getEngine()->debug(true);
$request = $client->getMessageFactory()->createRequest(\'http://jonnnnyw.github.io/php-phantomjs/4.0/6-debugging/\', \'GET\');
/**
 * @see JonnyW\\PhantomJs\\Http\\Response
 **/
$response = $client->getMessageFactory()->createResponse();
// Send the request
$client->send($request, $response);
var_dump($response->getContent());

## 主要想记录一下解决这个问题的心路历程。。。特别鸣谢羊的大力支持。。。。老司机万岁 ## 同一个文件，在cli模式下运行顺利，兴高采烈的架设到服务器， ## 然后http访问。。异常迅速 ## 这可是带网络请求的，这么快心都凉了一半 ## 日志打出来一看

## QXcbConnection: Could not connect to display PhantomJS has crashed

## 一脸懵逼 ## 最开始猜测是路径错误 ## 于是加入了

## $client->getEngine()->setPath(\'/usr/lib/phantomjs/phantomjs\');

## 发现还是错误 ## 这时候当然猜测权限不足 ## 多番尝试

## sudo chown www-data ./ -R

## sudo chgrpwww-data ./ -R

## sudo -u www-data -H php index.php

## 依然木有解决问题 ## 这时候想到cli和fpm的配置文件差异 ## 于是将cli模式的配置文件覆盖到fpm下

## cp /etc/php/7.0/cli/php.ini /etc/php/7.0/fpm/php.ini 

## 毫无卵用 ## 这个时候个人的力量就不行了 ## 老司机提议搜一搜 ## 上github一搜 ## 发现不少人类似问题 ## [https://github.com/ariya/phantomjs/issues/14376](\"https://github.com/ariya/phantomjs/issues/14376\") > ## The offscreen platform is a usable workaround for me with the stock Ubuntu package.

## 这2楼都人生淫家 ## 老司机瞬间猜测是木有display原因是缺少屏幕输出 ## 。。。 ## 总觉得自己用了假linux
