ruby - 我们可以看到使用机械 gem 发送的请求吗？

Question

我正在尝试使用 mechanize gem 构建 GET 请求，但我不断收到重定向错误。首先，我想知道是否有一种方法可以查看使用不同参数构建后发送的实际请求？

@agent.verify_mode = OpenSSL::SSL::VERIFY_NONE
cookie = Mechanize::Cookie.new('xyz_session', @tokenid)
cookie.domain = ".mydomain.com"
cookie.path = "/"
@agent.cookie_jar << cookie
@agent.redirection_limit=0
puts @agent.cookies
body = {}.to_json
#@agent.set_proxy("localhost",3000)
@agent.request_headers = {'Content-Type' => "application/json"}
       @agent.get("https://access.test.api.mydomain.com/oidc/v1/user/authorise?response_type=code&redirect_uri=http://localhost&client_id=testclient1&service=AccountSignInService&state=any-state") 
       expect(response.code).to eql(302), "Authorization Code couldn't be received"

我不断收到 Redirect limit of 0 reached (Mechanize::RedirectLimitReachedError)

如果我没有设置重定向限制，我会得到 connection refused: localhost:3000 (Net::HTTP::Persistent::Error)

因此我想首先检查我的请求是否按照我希望的方式发送...

只需为代理设置记录器即可获得请求/响应调试。

require 'mechanize'
require 'logger'

agent = Mechanize.new
agent.log = Logger.new(STDERR)
agent.get('http://google.com/')

运行这段代码会产生:
