Websockets服务器的SSL / TLS-Go lang

Question

I am using collider (https://github.com/webrtc/apprtc/tree/master/src/collider -a websockets server in go) and I am trying to add SSL/TLS support. For which I generated self-signed certificates:

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365

Enter PEM pass phrase:
Verifying - Enter PEM pass phrase:
Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:CA
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:testwebsite.com
Organizational Unit Name (eg, section) []:Engineering
Common Name (e.g. server FQDN or YOUR name) []:www.testwebsite.com
Email Address []:[e-mail]

When I run the collider, I see this error:

2017/06/05 21:25:50 Error Run: crypto/tls: failed to parse private key

When I generate using (based on http://www.kaihag.com/https-and-go/):

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout key.pem -out cert.pem

I get this error:

2017/06/05 22:11:31 http: TLS handshake error from <some-ip>:1082: remote error: unknown certificate

How to fix this?

Note: collider uses golang.org/x/net/websocket

I ended up obtaining the certs from: https://certbot.eff.org/#ubuntuxenial-other

certbot certonly --standalone -d example.com -d www.example.com

I had to use fullchain.pem instead of cert.pem for this collider to work:
