ruby on rails - Getting user information using either user.login or user.id -

-

तो मेरे पास एक url है जैसे 

  localhost / users /: id / posts

जो उस विशिष्ट उपयोगकर्ता की पोस्ट देता है अब यह आईडी या तो उसका लॉगिन (जो स्ट्रिंग है) या आईडी (user.id) हो सकता है जो कि तकनीकी रूप से एक पूर्णांक है, लेकिन पैराम्स [: आईडी] हमेशा एक स्ट्रिंग है तो मैं इसे कैसे क्रियान्वित कर सकता हूँ। 

  @user = params [: आईडी] .is_a? (स्ट्रिंग)? User.find_by_login (params [: id]): User.find (params [: id])

params [: id] हमेशा एक स्ट्रिंग है कोई विचार? धन्यवाद।

मैंने यह किया है, मेरे पास वास्तव में दो अलग-अलग नियंत्रक क्रियाएं हैं - < कोड> शो और show_by_login । मुझे लगता है कि यह कम अप्रत्याशित तरीके से है, और मेरे पास अधिक नियंत्रण है।

अपने लॉगिनों की विशिष्टता को लागू करना सुनिश्चित करें, उन्हें इंडेक्स करें, और यदि show_by_login आपके पास को सक्रिय करें रिकार्ड नहीं मिल सकता है: ActiveRecord :: RecordNotFound अपने आप को।

<पूर्व> डीईफ़ शो @ यूज़र = यूज़र.फंड (पैराम्स [: आईडी]) उत्तर_टो डॉट | प्रारूप | Format.html format.xml {रेंडर: xml = & gt; @ User.to_xml} end end def show_by_login @user = User.find_by_login (params [: लॉगिन]) जब तक कि यूजर वर्क ऐक्टिवर रिकार्ड :: रिकार्ड नॉटफॉन्ड एंड रेंडर: एक्शन = & gt; 'शो' एंड

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
