Hi.
I’m new to discourse and started diving into it by setting up a development system, following this howto.
Afterwards I was able to access my instance via ip address, but trying to access via hostname fails with following message:
Blocked host: discourse_example_net
To allow requests to discourse_example_net, add the following to your environment configuration:
config.hosts << “discourse_example_net”
I found this PR, but I don’t know how to set the env var.
Best,
Luis
You can prepend DISCOURSE_DEV_HOSTS=discourse_example_net to the command that starts the unicorn server, or you can set the variable in your ~/.bashrc (or the rc file of the shell you use).
我尝试了 DISCOURSE_DEV_HOSTS=xxx.ngrok.io d/unicorn，但很遗憾，它没有生效。
我猜你说的“不起作用”是指你仍然遇到了和原始发帖人相同的错误？看起来你正在使用 Docker 进行开发，因此需要在容器内部（而不是主机机器上）设置此环境变量。我开发时不使用 Docker，但看起来 d/boot_dev 可以为你在容器内设置变量：
d/boot_dev -e DISCOURSE_DEV_HOSTS=xxx.ngrok.io
然后运行 d/unicorn。
那最终总是会出现
