How to send a https request with a certificate golang

Question

I have a server which has a rest API running over https. I want to make a call to this rest api in my application which is running in different port but since this is over https I am getting

Post https://localhost:8080/api/v1/myapi: x509: certificate signed by unknown authority

I have 2 files pulic_key.pem and private_key which can used to verify the certificate. How can verify certificate while sending rest request using golang? I am using &http.Client{} to send a rest request. Here is what I am doing to ignore the certificate right now.

tr := &http.Transport{
TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
}

client := &http.Client{Transport: tr}

Answer 1

If the certificate is self-signed, you must add this option :

TLSClientConfig: &tls.Config{
   RootCAs:      caCertPool,
   InsecureSkipVerify: true,
},
