Maybe the best way is to use a traffic sniffer.

(Which would totally work...except in my case the traffic I want to see is encrypted. D'oh!)

blocks|key|4010007|text|或者，当我不知道确切的内部结构时，我的方法是直接抛出一个"debugger“语句，使用"script/server+--debugger”启动服务器，然后单步执行代码，直到我到达我想要的位置，然后在IRB.....that中开始一些检查可能会有所帮助(嘿，Luke+btw)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4010008|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Or my method of getting into things when I don't know the exact internals is literally just to throw in a "debugger" statement, start up the server using "script/server --debugger" and then step through the code until I'm at the place I want, then start some inspecting right there in IRB.....that might help (hey Luke btw)

blocks|key|4010037|text|我喜欢Wireshark，因为您可以在web浏览器客户端(通常是您的开发机器)上启动它，然后执行页面请求。然后，您可以找到HTTP数据包，右键单击并“跟随对话”，以查看HTTP的标题来回。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4010038|entityMap|0|LINK|mutability|MUTABLE|url|http://www.wireshark.org/^0|3|9|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I like <a href="http://www.wireshark.org/" rel="nofollow noreferrer">Wireshark</a> because you can start it listening on the web browser client end (usually your development machine) and then do a page request. Then you can find the HTTP packets, right click and "Follow Conversation" to see the HTTP with headers going back and forth.

blocks|key|5421415|text|很简单。只需看一下返回的响应。:)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5421416|有两个选项：|5421417|5421418|您的计算机上有源文件。编辑它。在适当的位置放置一个puts+response.inspect。记住删除它。|unordered-list-item|offset|length|style|CODE|5421419|Ruby有开放的类。找到正确的方法并重新定义它来做你想做的事情，或者使用别名和调用链来做这件事。可能有一个方法返回响应--抓取它，打印它，然后返回它。|5421420|5421421|下面是后一种选择的一个愚蠢的例子。|5421422|#+Somewhere+buried+in+ActiveResource:

It's easy. Just look at the response that comes back. :)

Two options:

<ul>
<li>You have the source file on your computer. Edit it. Put a <code>puts response.inspect</code> at the appropriate place. Remember to remove it.</li>
<li>Ruby has open classes. Find the right method and redefine it to do exactly what you want, or use aliases and call chaining to do this. There's probably a method that returns the response -- grab it, print it, and then return it.</li>
</ul>

Here's a silly example of the latter option.

<pre><code># Somewhere buried in ActiveResource:
class Network
 def get
 return get_request
 end

 def get_request
 "I'm a request!"
 end
end

# Somewhere in your source files:
class Network
 def print_request
 request = old_get_request
 puts request
 request
 end
 alias :old_get_request :get_request
 alias :get_request :print_request
end
</code></pre>

Imagine the first class definition is in the ActiveRecord source files. The second class definition is in your application somewhere.

<pre><code>$ irb -r openclasses.rb 
&gt;&gt; Network.new.get
I'm a request!
=&gt; "I'm a request!"
</code></pre>

You can see that it prints it and then returns it. Neat, huh?

(And although my simple example doesn't use it since it isn't using Rails, check out <code>alias_method_chain</code> to combine your alias calls.)

blocks|key|835247|text|只有在您还控制服务器的情况下，这才有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|835248|遵循服务器日志并搜索出被调用的URL：|835249|Completed+in+0.26889+(3+reqs/sec)+%7C+Rendering:+0.00036+(0%25)+%7C+DB:+0.02424+(9%25)+%7C+200+OK+[http://localhost/notifications/summary.xml?person_id=25738]|code-block|syntax|javascript|835250|然后在Firefox中打开它。如果服务器是真正的RESTful+(即，无状态)，您将得到与ARes相同的响应。|835251|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

This only works if you also control the server:

Follow the server log and fish out the URL that was called:

<pre><code>Completed in 0.26889 (3 reqs/sec) | Rendering: 0.00036 (0%) | DB: 0.02424 (9%) | 200 OK [http://localhost/notifications/summary.xml?person_id=25738]
</code></pre>

and then open that in Firefox. If the server is truely RESTful (ie. stateless) you will get the same response as ARes did.

blocks|key|835258|text|firefox+plugin+live+http+headers+(http://livehttpheaders.mozdev.org/)可以很好地做到这一点。或者你可以使用像http://www.httpviewer.net/这样的网站工具|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|835259|entityMap|0|LINK|mutability|MUTABLE|url|http://livehttpheaders.mozdev.org/|1|http://www.httpviewer.net/^0|Y|Y|0|2G|Q|1|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]|$A|R|B|S|1|T]]|C|$]]|$1|D|3|-4|5|6|7|U|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]]]

the firefox plugin live http headers (<a href="http://livehttpheaders.mozdev.org/" rel="nofollow noreferrer">http://livehttpheaders.mozdev.org/</a>) is great for this. Or you can use a website tool like <a href="http://www.httpviewer.net/" rel="nofollow noreferrer">http://www.httpviewer.net/</a>

Monkey patch the connection to enable Net::HTTP debug mode. See <a href="https://gist.github.com/591601" rel="noreferrer">https://gist.github.com/591601</a> - I wrote it to solve precisely this problem. Adding this gist to your rails app will give you <code>Net::HTTP.enable_debug!</code> and <code>Net::HTTP.disable_debug!</code> that you can use to print debug info.

Net::HTTP debug mode is insecure and shouldn't be used in production, but is extremely informative for debugging.

blocks|key|3164255|text|在config/initializers/中添加一个名为'debug_connection.rb'的新文件，其中包含以下内容：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3164256|class+ActiveResource::Connection

Add a new file to <code>config/initializers/</code> called <code>'debug_connection.rb'</code> with the following content:

<pre><code>class ActiveResource::Connection
 # Creates new Net::HTTP instance for communication with
 # remote service and resources.
 def http
 http = Net::HTTP.new(@site.host, @site.port)
 http.use_ssl = @site.is_a?(URI::HTTPS)
 http.verify_mode = OpenSSL::SSL::VERIFY_NONE if http.use_ssl
 http.read_timeout = @timeout if @timeout
 # Here's the addition that allows you to see the output
 http.set_debug_output $stderr
 return http
 end
end
</code></pre>

This will print the whole network traffic to $stderr.
