CCHttpRequest的用法很���

1、Get方法，�O置URL，���事件：

[html] view plaincopyprint?

--[[
    �O置ulr："http://blog.csdn.net/longolder"
    �O�：self:onResponseGet(event)
    方法：GET
--]]
local url = "http://blog.csdn.net/longolder"
local request = network.createHTTPRequest(function(event)
    self:onResponseGet(event)
end, url, "GET")
request:setTimeout(30)
request:start()

	--[[
		�O置ulr："http://blog.csdn.net/longolder"
		�O�：self:onResponseGet(event)
		方法：GET
	--]]
	local url = "http://blog.csdn.net/longolder"
	local request = network.createHTTPRequest(function(event)
		self:onResponseGet(event)
	end, url, "GET")
	request:setTimeout(30)
	request:start()

默�J超�r�r�g��10s，�@�e�{用setTimeout�O置30s超�r

2、POST方法，�cGET方法相似，只不�^要另外添加���：

[html] view plaincopyprint?

-- �{用addPOSTValue向Form中添加�I值��例如：key:value
for key, value in pairs(dataInfo) do
    request:addPOSTValue(key, value)
end

	-- �{用addPOSTValue向Form中添加�I值��例如：key:value
	for key, value in pairs(dataInfo) do
		request:addPOSTValue(key, value)
	end

dataInfo是一��保存要�l送���的table集合

下面是回�{方法：

[html] view plaincopyprint?

function HttpRequestTest:onResponseGet(event)
    local request = event.request
    if event.name ~= "completed" then -- ����completed表示正常�Y束此事件
        print("request:getErrorCode(), request:getErrorMessage() ", request:getErrorCode(), request:getErrorMessage())
        return
    end
    local code = request:getResponseStatusCode()
    if code ~= 200 then -- 成功
        print("code ", code)
        return
    end
    local strResponse = string.trim(request:getResponseString())
    print(strResponse)
end

function HttpRequestTest:onResponseGet(event)
	local request = event.request
	if event.name ~= "completed" then -- ����completed表示正常�Y束此事件
		print("request:getErrorCode(), request:getErrorMessage() ", request:getErrorCode(), request:getErrorMessage())
		return 
	end
	local code = request:getResponseStatusCode()
	if code ~= 200 then -- 成功
		print("code ", code)
		return 
	end
	local strResponse = string.trim(request:getResponseString())
	print(strResponse)
end

常用的��B�a有以下���值：

200 - 服�掌鞒晒Ψ祷鼐W�

404 - �求的�W�不存在

503 - 服�掌��r不可用
