本文详细介绍了如何使用Cocos2d-x框架进行HTTP POST请求，并通过回调函数处理响应数据，包括设置请求头、数据、响应回调及错误处理。

void CClass::PostUpdateToUrl(CCObject* apTarget, const char* apUrl, const char* apData, unsigned long aulLength)
{
	cocos2d::extension::CCHttpRequest* request = new cocos2d::extension::CCHttpRequest();
	request->setUrl(apUrl);
	request->setRequestType(cocos2d::extension::CCHttpRequest::kHttpPost);
	std::vector<std::string> headers;
	headers.push_back("Content-Type: application/json; charset=utf-8");	//根据情况修改
	request->setHeaders(headers);
	request->setRequestData(apData ,aulLength);
	request->setResponseCallback(apTarget, httpresponse_selector(CCommHttp::onHttpRequestUpdate));
	request->setTag("Post_My_Data");	//根据情况修改
	cocos2d::extension::CCHttpClient::getInstance()->send(request);
	request->release();

	return ;
}

void CCommHttp::onHttpRequestUpdate(cocos2d::CCNode *sender ,void *data)
{
	AllocConsole();
	freopen("CONIN$", "r", stdin);
	freopen("CONOUT$", "w", stdout);
	freopen("CONOUT$", "w", stderr);
	cocos2d::extension::CCHttpResponse *response = (cocos2d::extension::CCHttpResponse*)data;  
	if (!response)  
	{
		return;  
	} 
	if (0 != strlen(response->getHttpRequest()->getTag())) 
	{
		CCLog("%s completed", response->getHttpRequest()->getTag());
	}
	int statusCode = response->getResponseCode();
// 	char statusString[64] = {};
// 	sprintf(statusString ,"Http status code:%d ,tag = %s" ,statusCode ,response->getHttpRequest()->getTag());
	CCLog("response code:%d" ,statusCode);
	if (!response->isSucceed())
	{
		CCLog("response failed");
		CCLog("error buffer:%s" ,response->getErrorBuffer());
	}
	std::vector<char> *buffer = response->getResponseData();
	printf("Http response,dump data:");
	for (unsigned int i=0; i<buffer->size(); i++)
	{
		printf("%c" ,(*buffer)[i]);
	}

std::string result(buffer->begin(),buffer->end()); ;CCMessageBox(result.data(), "1");

用法

char* url = "http://www.oschina.net/action/api/news_list";
char* data = "catalog=2&pageIndex=1&pageSize=5";
PostUpdateToUrl(this, url,data ,strlen(data));
