问题描述
有人可以向我解释为什么在执行此POST时出现此错误吗?我从 Ruby-docs中提取了该代码段页面.
Can someone explain to me why I am getting this error when doing this POST? I pulled the snippet from the Ruby-docs page.
undefined method `hostname' for #URI::HTTP:0x10bd441d8 URL:http://ws.mittthetwitapp.com/ws.phpmywebservice (NoMethodError)
也许我错过了需求之类的东西吗?
Perhaps I am missing a require or something?
require 'net/http'
uri= URI('http://ws.mywebservice.com/ws.php')
req = Net::HTTP::Post.new(uri.path)
req.set_form_data('xmlPayload' => '<TestRequest><Message>Hi Test</Message></TestRequest>')
res = Net::HTTP.start(uri.hostname, uri.port) do |http|
http.request(req)
end
case res
when Net::HTTPSuccess, Net::HTTPRedirection
# OK
else
res.value
end
推荐答案
如果您使用的是1.9.3之前的Ruby版本,则应使用uri.host
.
If you're using a version of Ruby prior to 1.9.3, you should use uri.host
.
URI#hostname
是在Ruby 1.9.3中添加的. 与URI#host
不同之处在于,它从IPv6主机名中删除了括号.对于非IPv6主机名,其行为应相同.
URI#hostname
was added in Ruby 1.9.3. It is different than URI#host
in that it removes brackets from IPv6 hostnames. For non-IPv6 hostnames it should behave identically.
实现(来自 APIdock ):
def hostname
v = self.host
/\A\[(.*)\]\z/ =~ v ? $1 : v
end
