cocos2dx http 链接以及采集数据 小例子

大家好，前些日子一直在忙，忙过了一个cocos2dx小游戏之后，又在研究着android平台的东西，现在想跟大家分享一下小知识http小例子

在新建的helloworld项目中导入外部头文件

#include "cocos-ext.h"       USING_NS_CC_EXT; 

如有不懂如何导入可看http://blog.csdn.net/five50/article/details/8748833

在init函数中这样子写

bool HelloWorld::init(){    bool bRet = false;    do     {        CC_BREAK_IF(! CCLayer::init());cocos2d::extension::CCHttpRequest* request = new cocos2d::extension::CCHttpRequest();request->setUrl("http://www.baidu.com");request->setRequestType(cocos2d::extension::CCHttpRequest::kHttpGet);request->setResponseCallback(this, httpresponse_selector(HelloWorld::onHttpRequestCompleted));request->setTag("GET test1");cocos2d::extension::CCHttpClient::getInstance()->send(request);request->release();        bRet = true;    } while (0);    return bRet;}

增加多一个函数onHttpRequestCompleted该函数为接收数据回调函数

如下

void HelloWorld::onHttpRequestCompleted( cocos2d::extension::CCHttpClient *sender, cocos2d::extension::CCHttpResponse *response ){std::vector<char> *buffer = response->getResponseData();printf("Http Test, dump data: ");for (unsigned int i = 0; i < buffer->size(); i++){    CCLOG("%c", (*buffer)[i]);}printf("\n");}
