RAILS EXCEPTION: undefined method `keys' for nil:NilClass
I can't figure out why in the following line of code
res = https.get(url开发者_JAVA技巧, nil)
The application stops and give me the following exception:
undefined method `keys' for nil:NilClass
The strange things is that this error happens only in my development enviroment, when I put the application online (heroku), everyhthing work like a charm.
That above line of code, use this inclusion:require 'net/https'
Is anybody able to explain me why ?
TnxIf you don't want to pass any headers just use:
res = https.get(url, {})
in the documentation for Net::HTTP
this method definition is
def get(path, initheader = {}, dest = nil, &block) # :yield: +body_segment+
res = nil
if HAVE_ZLIB
unless initheader.keys.any?{|k| k.downcase == "accept-encoding"}
initheader["accept-encoding"] = "gzip;q=1.0,deflate;q=0.6,identity;q=0.3"
@compression = true
....
in your code initheader
is nil
so error happens on line four initheader.keys
It may work fine on heroku because there is if HAVE_ZLIB
which can be faulse
so code is skipped.
