cocos2dx http 鏈接以及採集數據 小例子

大家好，前些日子一直在忙，忙過了一個cocos2dx小遊戲之後，又在研究着android平臺的東西，現在想跟大家分享一下小知識http小例子

在新建的helloworld項目中導入外部頭文件

#include "cocos-ext.h"       
USING_NS_CC_EXT; 

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

在init函數中這樣子寫

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;
}

增加多一個函數onHttpRequestCompleted該函數爲接收數據回調函數

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");
}
