Question

我正在使用Rails 4.2.7。如何获取Net :: HTTP :: Post请求中设置的参数？我在我的Rails控制台中试过这个

2.3.0 :001 > url = "https://ruby-doc.org/stdlib-2.1.1/libdoc/net/http/rdoc/Net/HTTP/Post.html"
 => "https://ruby-doc.org/stdlib-2.1.1/libdoc/net/http/rdoc/Net/HTTP/Post.html" 
2.3.0 :002 > uri = URI(url)
 => #<URI::HTTPS https://ruby-doc.org/stdlib-2.1.1/libdoc/net/http/rdoc/Net/HTTP/Post.html> 
2.3.0 :003 > params = {"submitbutton" => "View"}
 => {"submitbutton"=>"View"} 
2.3.0 :004 > req = Net::HTTP::Post.new(uri)
 => #<Net::HTTP::Post POST> 
2.3.0 :005 > req.set_form_data(params)
 => "application/x-www-form-urlencoded" 
2.3.0 :008 > req.uri.params
NoMethodError: undefined method `params' for #<URI::HTTPS:0x007fe2aefba980>
Did you mean?  parser

我也试过调用“req.params”并获得相同的“未定义方法错误。”

请检查：

uri = URI('http://www.example.com/search.cgi')
res = Net::HTTP.post_form(uri, 'submitbutton' => 'View')
puts res.body

参考： https://ruby-doc.org/stdlib-2.1.1/libdoc/net/http/rdoc/Net/HTTP.html

在RoR中，如何在Net :: Http :: Post请求中设置参数？
