\"example\"\r\n<\/a><\/div>\r\n\r\n\r\nThis simple peace of code could be very helpful in case of debugging HTTP api.\r\nInstallation is pretty simple:\r\n
gem install http_logger<\/code><\/pre>\r\nAnd\r\n
require 'http_logger' Net::HTTP.logger = Logger.new(...) Net::HTTP.colorize = true <\/code><\/pre>\r\nIn rails you don’t have to do anything, as defaults are:\r\n
# Net::HTTP.logger = Rails.logger if defined?(Rails). # Net::HTTP.colorize = true<\/code><\/pre>\r\n \r\n\r\nTODO for v2:\r\n
Completed 200 OK in 150ms (Views: 13.5ms | ActiveRecord: 0.0ms | <strong>Net::HTTP: 115.5ms<\/strong>) <\/code><\/pre>\r\n
Offtop for ruby lovers<\/h3>\r\nWant to show the most interesting part in the source code:\r\n
 def request(request, body = nil, &block) ... <strong>response<\/strong> = request_without_log(request, body, &block) ensure ...... if defined?(<strong>response<\/strong>) rails_log("Response body", <strong>response<\/strong>.body) unless response.body.is_a?(Net::ReadAdapter) end end<\/code><\/pre>\r\nPay attention on how ensure<\/strong> works with context.\r\nThe response<\/em> local variable defined inside of def<\/em> and ensure<\/em>, but still accessible after ensure if there was no exception inside of request_without_log<\/em>.
