使用服务器内置的PHP构建的Google Cloud Shell问题-无法在端口8080上连接到Cloud Shell

Question

I can't get to work my simple index.php file on Google cloud shell. I start my server with command php -S localhost:8080 -t test/ . Before that I navigate just before test folder. I click Web preview in upper right corner and get error: Could not connect to Cloud Shell on port 8080 What could be the problem?

Answer 1

经过数小时的工作和重置...我只是从php -S localhost:8080 -t test/更改为php -S 127.0.0.1:8080 -t test

Answer 2

In Cloud Shell localhost resolves to both IPv4 and IPv6 addresses:

$ head -3 /etc/hosts
# Kubernetes-managed hosts file.
127.0.0.1       localhost
::1     localhost ip6-localhost ip6-loopback

It appears that when this is the case, PHP's builtin web server only binds to the IPv6 address ; however, Cloud Shell web preview connects to the IPv4 addresses. Your solution to bind directly to the IPv4 loopback interface (127.0.0.1) is probably the best, for now.
