用于express.js环境.有什么建议？

我正在研究YouTube broadcast示例示例.我创建了一个样本Java Project并添加了所需的罐子.但是,当我尝试运行该项目时,它会抛出异常.

例外:

我从这个GitHub存储库下载了该项目.

我收到了错误 ERROR 1066 (42000): Not unique table/alias:

我无法弄清楚它有什么问题.

我在卷曲使用TLS1.2的HTTPS网址时遇到问题,在我的curl操作中,我将登录数据发布到网站并将其保存在cookiefile中.我得到的错误信息是这个

 error:14077438:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert internal error

我试过设置VERIFYPEER并且VERIFYHOST为0但是这似乎不起作用,有什么建议吗？

以下是我使用的版本:

• OpenSSL版本为0.9.8b
• CURL版本是7.24.0
• PHP是5.3

这是代码:

$setuplogin = curl_init(); 
curl_setopt ($setuploginurl, CURLOPT_URL, $url); 
curl_setopt ($setuploginurl, CURLOPT_SSL_VERIFYPEER, 1); 
curl_setopt ($setuploginurl, CURLOPT_SSL_VERIFYHOST, 1);
curl_setopt ($setuploginurl, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 'CURL_SSLVERSION_TLSv1_2');
curl_setopt ($setuploginurl, CURLOPT_POSTFIELDS, 'username=uname&password=pword&act=login&submit=Login');
curl_setopt ($setuploginurl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36"); 
curl_setopt (setuploginurl, CURLOPT_TIMEOUT, 60); 
curl_setopt ($setuploginurl, CURLOPT_COOKIESESSION, TRUE); 
curl_setopt ($setuploginurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($setuploginurl,  CURLOPT_HEADER, 1);
curl_setopt ($setuploginurl,CURLOPT_ENCODING,"gzip");
curl_setopt ($setuploginurl, CURLOPT_POST, true);

我已经查看了我可以找到的用于设置元数据的每个示例AVAssetExportSession,但即使音频导出工作正常(结果音频文件播放正常),仍然没有随文件导出的元数据.我正在使用Xcode 4.5,目标构建iOS 5,测试设备iOS 6.请看下面我正在使用的代码,请让我知道我做错了什么.

// for metadata export

当我尝试JSON编码NSDate对象时,我得到了这个异常.我相信NSDate与JSON编码不兼容.但我必须编码日期.任何解决方案？

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid type in JSON write (__NSDate)'

stack:PHP 5.4.23,php-fpm,nginx 1.4.x,centos 6.5

我试图安装xdebug,不得不运行phpize命令.

我已经安装了php5-devl并且pecl命令工作

当我运行命令时,它给了我以下错误输出:

# phpize
Can't find PHP headers in /usr/include/php
The php-devel package is required for use of this command.

如何解决这个错误？

我有一个嵌入式HTML电子邮件,我正在使用base64编码图像.通过chrome访问时,图像不会显示在Gmail中.但通过邮件客户端(Mac上的Mail应用程序)访问相同的邮件时,它可以正常工作.我已正确设置标题.任何的想法？

我想安装的最新版本NodeJS上Ubuntu Zesty 17.04.但无论是使用apt-get还是尝试从nodesource ppa下载它,我总是拥有版本4.7.2.

apt-get的

sudo apt-get update
sudo apt-get install nodejs npm

节点PPA

curl -sL https://deb.nodesource.com/setup_6.x | sudo bash -
sudo apt-get update
apt-get install nodejs npm

结果

$> node -v
v4.7.2

我怎样才能获得NodeJS的6.9版本？
