【quick-cocos2d-x】 CCHttpRequest用法

CCHttpRequest的用法很��

1、Get方法，�置URL，��事件：

[html] view plaincopyprint?

1. --[[

2. �置ulr："http://blog.csdn.net/longolder"

3. ��：self:onResponseGet(event)

4. 方法：GET

5. --]]

6. localurl="http://blog.csdn.net/longolder"

7. localrequest=network.createHTTPRequest(function(event)

8. self:onResponseGet(event)

9. end,url,"GET")

10. request:setTimeout(30)

11. request:start()

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

默�超����10s，���用setTimeout�置30s超�

2、POST方法，�GET方法相似，只不�要另外添加��：

--�用addPOSTValue向Form中添加�值�例如：key:value

forkey,valueinpairs(dataInfo)do

request:addPOSTValue(key,value)

end

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

dataInfo是一�保存要�送��的table集合

下面是回�方法：

functionHttpRequestTest:onResponseGet(event)

localrequest=event.request

ifevent.name~="completed"then--��completed表示正常�束此事件

print("request:getErrorCode(),request:getErrorMessage()",request:getErrorCode(),request:getErrorMessage())

return

end

localcode=request:getResponseStatusCode()

ifcode~=200then--成功

print("code",code)

localstrResponse=string.trim(request:getResponseString())

print(strResponse)

function HttpRequestTest:onResponseGet(event) local request = event.request if event.name ~= "completed" then -- ��completed表示正常�束此事件 print("request:getErrorCode(),request:getErrorMessage() ",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���有以下��值：

200 - 服�器成功返回��

404 - �求的��不存在

503 - 服�器��不可用
