自己封装的cocos2dx中封装pomelo并导出给javascript使用-优快云博客

本文介绍了一个Cocos2d-x项目中集成Pomelo网络库的过程，包括C++类定义、实例化方法、连接服务器及发送请求等功能实现，并提供了具体的代码示例。

#ifndef __CCPOMELO_H__
#define __CCPOMELO_H__
#include "cocos2d.h"

class CCPomelo : public cocos2d::CCObject
{
public:
CCPomelo(){};
~CCPomelo(){};

int connect(const char* addr, unsigned short port);

int request(const char* route, const char* msg);

void onRequestCallback(int status, const char* msg);

static CCPomelo* getInstance();

protected:
void* m_client;

protected:
static CCPomelo* m_pInstance;
};

#endif

******************CCPomelo.cpp文件如下******************

#include "CCPomelo.h"
#include "pomelo.h"

USING_NS_CC;

CCPomelo* CCPomelo::m_pInstance = NULL;
CCPomelo* CCPomelo::getInstance()
{
if( !m_pInstance )
{
m_pInstance = new CCPomelo();
}
return m_pInstance;
}

void on_request_cb(pc_request_t *req, int status, json_t *resp) {
if(status == -1) {
//printf("Fail to send request to server.\n");
return;
} else if(status == 0) {
//printf("server response: %s\n", json_dumps(resp, 0));
}

// release relative resource with pc_request_t
json_t *msg = req->msg;

CCPomelo::getInstance()->onRequestCallback(status, json_dumps(msg, 0));

pc_request_destroy(req);
}

int CCPomelo::connect(const char* addr, unsigned short port)
{
m_client = pc_client_new();
struct sockaddr_in address;
memset(&address, 0, sizeof(struct sockaddr_in));
address.sin_family = AF_INET;
address.sin_port = htons(port);
address.sin_addr.s_addr = inet_addr(addr);
return pc_client_connect((pc_client_t*)m_client, &address);
}

void CCPomelo::onRequestCallback(int status, const char* msg)
{
CCLog(msg);
}

int CCPomelo::request(const char* route, const char* msg)
{
pc_request_t *request = pc_request_new();
json_error_t error;
return pc_request((pc_client_t*)m_client, request, route, json_loads(msg, 0, &error), on_request_cb);
}

然后导出到Js 可以看 (coco2dx_root)/tools/tojs/README.mdown，详细说明了如何导出Js

导出的时候我发现个问题，unsigned short port 导出Js的文件有问题，打开jsb_cocos2dx_extension_auto.cpp 加入jsval_to_uint16(cx,argv[1],&arg1);

最后脚本中调用：

cc.Pomelo.getInstance().connect("127.0.0.1", 3010);
cc.Pomelo.getInstance().request("connector.helloHandler.hi", "{'msg' : 'hi~'}".replace(/'/g,"\""));
