无法连接到www.googleapis.com端口443:网络无法访问

Question

我正在尝试在我的网站中使用Google Client API在Symfony2中编写谷歌登录.我按照这里的说明进行操作,但是当我调用$ client-> authenticate($ code)时; 命令异常抛出告诉:
无法连接到www.googleapis.com端口443:网络无法访问有
什么问题？

Answer 1

解决方案2(来自更新).它似乎是ipv6接口和curl与php的一些错误,所以另一个解决方案是在curl函数中设置appropiate选项,用你的PHP脚本中的ipv4连接到远程服务器

curl_setopt($ curl,CURLOPT_IPRESOLVE,CURL_IPRESOLVE_V4);

解决方案1.

同样的事情发生在我身上(通过将ip v4和主机名添加到/ etc/hosts文件中解决),正如@ hans-z在另一个回答评论中指出的那样,我尝试使用next命令来验证网络问题.

curl -v https://www.googleapis.com 

事实证明它是随机的,只有十分之一的尝试curl命令可以连接到服务器,响应是这样的:("La red es inaccesible"意思是英文"network unreachable":))

$ curl -v https://www.googleapis.com
* Rebuilt URL to: https://www.googleapis.com/
* Hostname was NOT found in DNS cache

* Failed to connect to www.googleapis.com port 443: La red es inaccesible
* Closing connection 0
curl: (7) Failed to connect to www.googleapis.com port 443: La red es inaccesible

成功的回应是:

奇怪的消息是"在DNS缓存中找不到主机名",我使用谷歌DNS的4.4.4.4和8.8.8.8,所以我使用curl命令输出中的ipv4将该域添加到我的/ etc/hosts文件中解决了.

#/etc/hosts
...
64.233.186.95 www.googleapis.com
#DONT COPY THIS IP, USE THE ONE FROM YOUR CURL OUTPUT

Answer 2

看起来像是传出防火墙/代理/网络问题。您应该能够使用ping和curl从运行您的网站的计算机来验证这一点。
