使用Ruby gem Typhoeus的Api请求

Question

下面的请求有什么问题？

request = Typhoeus::Request.new("http://fluidsurveys.com/api/v2/groups",
                                    method: :get,
                                    userpwd: "test_user:test_password",
                                    headers: { 'ContentType' => "application/json"})
response = request.body
puts response

这将返回undefined method body for #<Typhoeus::Request:0x007f8e50d3b1d0> (NoMethodError)

下面的请求在httparty中很好地工作

call= "/api/v2/groups/"
auth = {:username => "test_user", :password => "test_password"}
url = HTTParty.get("http://fluidsurveys.com/api/v2/groups",
                   :basic_auth => auth,
                   :headers => { 'ContentType' => 'application/json' } )
response = url.body
puts response

编辑：

我试过这个：

response = request.response
puts response.body

没有运气。我收到这个：undefined method body for nil:NilClass (NoMethodError)

您需要在响应体可用之前完成get。

编辑:这是一个可操作的解决方案。它不使用你的网站，我甚至不能手动访问。但是，这会返回响应代码200和response_body。在我的调试器中运行这个程序会显示完整的响应，您可以看到使用"puts response.inspect“。

class TyphoeusTry
  require 'typhoeus'
  request = Typhoeus::Request.new("http://www.google.com",
                                  method: :get,
                                  userpwd: "test_user:test_password",
                                  headers: { ContentType: "application/json"})
  response = request.run
  puts response.response_body
end

问题是你并没有真正执行你的请求。下面的代码应该可以工作。

request = Typhoeus::Request.new("http://fluidsurveys.com/api/v2/groups",
                                method: :get,
                                userpwd: "test_user:test_password",
                                headers: { 'ContentType' => "application/json"})

request.run
response = request.response
response_code = response.code
response_body = response.body
