Don’t use Go’s default HTTP client (in production)

Writing Go programs that talk to services over HTTP is easy and fun. I’ve written numerous API client packages and I find it an enjoyable task. However, I have run into a pitfall that is easy to fall into and can crash your program very quickly: the default HTTP client. TL;DR: Go’s http package doesn’t specify request timeouts by default, allowing services to hijack your goroutines. Always specify

http.DefaultClientはtimeout=0となっているので本番環境では使わないようにしよう
