如何打印有关NET：HTTPRequest的信息以进行调试？ [英] How can I print information about a NET:HTTPRequest for debug purposes?

问题描述

我是来自Java的Ruby的新手。我正在尝试创建一个http get请求，我得到一个400的http响应代码。我通过http调用的服务非常特别，我很确定我的请求不完全正确。在我执行头部请求（下面）之后查看 req 对象是有帮助的，以便仔细检查正在发送的request_headers是我认为我的发送。有没有办法打印出req对象？

I'm new to Ruby coming from Java. I'm trying to make a http get request and I'm getting an http response code of 400. The service I'm calling over http is very particular and I'm pretty sure that my request isn't exactly correct. It'd be helpful to "look inside" the req object after I do the head request (below) to double check that the request_headers that are being sent are what I think I'm sending. Is there a way to print out the req object?

req = Net::HTTP.new(url.host, url.port)
req.use_ssl = true

res = req.head(pathWithScope, request_headers)

code = res.code.to_i
puts "Response code: #{code}"

我试过这个： puts请求调试：＃{req.inspect}但它只打印这个：＃< Net :: HTTP www.blah.com:443 open = false>

I tried this: puts "Request Debug: #{req.inspect}" but it only prints this: #<Net::HTTP www.blah.com:443 open=false>

推荐答案

使用 set_debug_output 。

http = Net::HTTP.new(url.host, url.port)
http.set_debug_output($stdout) # Logger.new("foo.log") works too
