通过SSL发布UTF-8时,HEROKU上的"EOFError:文件结束"

Question

我在heroku上有一个奇怪的错误.为了重现它,我必须在请求体中使用任何UTF-8字符进行大的(超过几KB)HTTPS POST.这是一个例子:

require "net/https"
require "uri"

#Accutally I've ecountered this bug while posting to another server
url = URI.parse("https://api.heroku.com/myapps")

#It's Ukrainian 'oiced velar plosive G' letter
payload = "?"*10000
request = Net::HTTP::Post.new(url.path)
request.body = payload
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.read_timeout = 500
http.start {|http| http.request request }

在本地机器的irb上运行这样的脚本给了我:

#<Net::HTTPUnauthorized 401 Unauthorized readbody=true> 

......这是预期的,但是在heroku雪松上,在"heroku控制台"上运行...在大约60秒内,我得到:

EOFError: end of file reached

我该怎么办？

Answer 1

我必须将 ruby​​ 版本添加到Gemfile中，因为默认 Cedar 的 ruby​​ 是 1.9.2（在通过 SSL 传递 UTF-8 字符串时存在错误）

source 'https://rubygems.org'
ruby "1.9.3"

gem 'rails', '3.2.7'
gem 'pg'
