我正在编写一个脚本来从GitHub v4 API获取数据。但是我的Ruby脚本失败了EOFError。如何避免EOFError？
以下代码在失败end of file reached (EOFError)。我运行了10次脚本，但没有人成功。
require 'net/http'
require 'uri'
uri = URI.parse 'https://api.github.com/graphql'
header = {
'Authorization' => 'bearer MY_GITHUB_TOKEN',
}
Net::HTTP.new uri.host, uri.port do |http|
http.use_ssl = true
end.start do |http|
req = Net::HTTP::Post.new uri.path, header
req.body = " \
{ \
\"query\": \"query { viewer { login }}\" \
} \
"
http.request req do |res|
p res.code
p res.message
p res.body
p res.read_body
res.read_body do |body|
p body
end
end
end
我正在使用ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux] 由rbenv-build编译的Ruby 。我得到了堆栈跟踪。

由于我的错误猜测。
Net::HTTP.new 不占用任何块，因此下面的代码
Net::HTTP.new uri.host, uri.port do |http|
http.use_ssl = true
end.start ...
应该
(Net::HTTP.new uri.host, uri.port).tap do |http|
http.use_ssl = true
end.start ...
