问题
I'm unable to get Mechanize to load a page that used to work -- it's reliably failing with a Errno: ECONNRESET: Connection reset by peer - SSL_connect
message. Any suggestions as to what I should try or details I should look at? (Please see "what I've tried" below...)
Update 1
Taking a hint from a related S.O. post, I tried accessing the site directly with Net::HTTP
. When I set http.ssl_version = :TLSv1
, I get a redirect rather than an error (as it should be). So my question becomes: how can I configure Net::HTTP's underlying ssl_version
parameters from within Mechanize
?
Thanks...
The symptoms:
$ rails console
>> a = Mechanize.new
=> #<Mechanize:0x007fd26789b8e0 ...>
>> p = a.get("http://sce.com")
# (...after a long pause...)

What I've tried:
- I've tried the same URL from a Firefox web browser. It works.
- I've explicitly set the Mechanize
request_headers
to exactly mimic the Firefox browser. No change. - I've updated my
ssl/cert.pem
file (a second time) as described in this S.O post. No change. - I've tried different sites:
www.pge.com
andwww.sdge.com
. Both work. There's something different about thewww.sce.com
site.
Success with Net::HTTP
Here's an example of Net::HTTP working:
$ irb
>> require 'net/https'
=> true
>> require 'uri'
=> false
>> uri = URI.parse("https://www.sce.com/")
=> #<URI::HTTPS:0x007facab8f6ba0 URL:https://www.sce.com/>
>> http = Net::HTTP.new(uri.host, uri.port)
=> #<Net::HTTP www.sce.com:443 open=false>
>> http.use_ssl = true
=> true
>> http.ssl_version = :TLSv1 # <= this line makes all the difference
=> :TLSv1
>> r = http.start { |agent| p agent.get(uri.path) }
=> #<Net::HTTPFound 302 Found readbody=true>
>> r.to_hash

The folks on the Mechanize mailing list kindly provided the answer:
agent = Mechanize.new do |a|
a.ssl_version = :TLSv1
end
