消費非Rails的REST API使用的ActiveResource

Question

我使用的ActiveResource對非Rails的REST API ......其實即便是「休息」的一部分是值得懷疑的，但他們的嘗試：

Although RESTful applications are ideally stateless, the ALM platform requires sessions to manage locking, client life time, and perform other basic tasks. Session management is performed using a cookie named QCSession.

無論如何，我需要發出一個GET到「身份驗證點/身份驗證」以獲得用戶身份驗證並取回cookie。只是不知道該怎麼做。這是我有，但我得到一個404錯誤：

class AlmActiveResource < ActiveResource::Base 
    attr_accessor :lwsso_cookie, :qcsession_cookie 

    self.site  = "http://alm_url/qcbin/" 
    self.user  = "name" 
    self.password = "pw" 

    def self.authentication 
    @auth_point = "authentication-point/authenticate" 
    self.prefix(@auth_point) 
    meow = self.get(:authenticate) 
    Rails.logger.debug("Meow: #{meow.inspect}") 

    end 
end

我有完全相同的問題。我終於必須把所有東西都放在控制器中，才能與ALM交談。這不是最好的，但它的工作原理。下面是在ReleaseCycles控制器Index操作：

def index 
    conn=getAuthenticatedCurl 
    conn.url="#{$HPQC_REST_URL}/release-cycles" 
    conn.perform 
    results=conn.response_code 
    hash=Hash.from_xml(conn.body_str) 
    respond_to do |format| 
     format.html { render :xml => hash } 
     format.xml { render :xml => hash } 
     format.json { render :json => hash } 
    end 
    conn.url=$HPQC_LOGOUT_URL 
    conn.perform 
    conn.close 
    return results 
end 

我創建的ApplicationController中的get 「getAuthenticatedCurl」。它看起來像：

$HPQC_HOST = "http://<your_alm_server>:8080" 
    $HPQC_REST_URL = "#{$HPQC_HOST}/qcbin/rest/domains/<DOMAIN>/projects/<PROJECT>" 
    $HPQC_LOGIN_URL = "#{$HPQC_HOST}/qcbin/authentication-point/authenticate" 
    $HPQC_LOGOUT_URL = "#{$HPQC_HOST}/qcbin/authentication-point/logout" 

    def getAuthenticatedCurl 
    @_conn = Curl::Easy.new($HPQC_LOGIN_URL) 
    @_conn.verbose = true 
    @_conn.http_auth_types = :basic 
    @_conn.userpwd = '<username>:<password>' 
    @_conn.enable_cookies = true 
    @_conn.cookiejar = 'cookies.txt' 
    @_conn.perform #creates the first cookie instance, which allows subsequent calls to the HPQC API 
    puts "connected...." 
    return @_conn 
    end 

它不漂亮，但它的工作原理，它的速度很快。我的下一步是做一個ActiveResource相同的事情。希望它有幫助，祝你好運！
