1 在服务器端使用sqllite编写数据库
常见命令是：sqlite3 tank.db
进入之后创建表：
create table tscore (
id integer primary key autoincrement,
username varchar(32) unique not null,
totalscore integer not null,
score integer not null
);
在服务器端编写程序：
#include<stdio.h>
#include<sqlite3.h>
#include<string.h>
#include<stdlib.h>
int main()
printf("Content-type:text/html\n\n");
//set Score to Database
char * queryString = getenv("QUERY_STRING");
if(queryString == NULL)
{
printf("Err:queryString is NULL");
return 0;
}
//totalscore=%d&score=%d&user=user%d
//获取参数
char *totalScore = strtok(queryString,"&");
char *score = strtok(NULL,"&");
char *username = strtok(NULL,"&");
strtok(totalScore,"=");
totalScore = strtok(NULL,"=");
strtok(score,"=");
score = strtok(NULL,"=");
//写数据库
sqlite3* db;
int ret = sqlite3_open("/usr/lib/cgi-bin/tank.db",&db);
if(ret != SQLITE_OK)
{
printf("open database error:%s",sqlite3_errstr(sqlite3_errcode(db)));
return 0;
}
char sql[2048];
sprintf(sql,"insert into tscore(username,totalScore,score) values('%s',%s,%s)",usernam| e,totalScore,score);
ret = sqlite3_exec(db,sql,NULL,NULL,NULL);
printf("%s<br>",sql);
if(ret != SQLITE_OK)
{
printf("insert data error:%s",sqlite3_errstr(sqlite3_errcode(db)));
sqlite3_close(db);
return 0;
}
return 0;
}
编译：
sudo gcc setScore.c -o setScore.cgi -lsqlite3
注意要加上最后面的-lsqlite3,不然
设置tank.db的权限
在浏览器中输入以下链接地址：
http://192.168.28.155/cgi-bin/setScore.cgi?totalscore=100&score=1011&username=toto
网页中的输出运行结果：
tank.db中的内容如下：

3 HttpClient的客户端：
T24HttpClient.h（Get方式）
#ifndef __T24HttpClient_H__
#define __T24HttpClient_H__
#include "cocos2d.h"
#include "cocos-ext.h"
#include "TBack.h"
USING_NS_CC;
USING_NS_CC_EXT;
class T24HttpClient :public TBack
{
public:
CREATE_FUNC(T24HttpClient);
bool init();
static CCScene * scene();
void HttpResponse(CCHttpClient*client, CCHttpResponse*response);
};
#endif
T24HttpClient.cpp
#include "T24HttpClient.h"
CCScene* T24HttpClient::scene()
{
CCScene* scene = CCScene::create();
T24HttpClient* layer =T24HttpClient::create();
scene->addChild(layer);
return scene;
}
bool T24HttpClient::init()
{
TBack::init();
//向服务器发送请求（http报文）单例
CCHttpClient* client =CCHttpClient::getInstance();
//创建一个request对象
CCHttpRequest* request =new CCHttpRequest();
//设置访问URL
request->setUrl("http://192.168.192.130/cgi-bin/setScore.cgi?username=xxx&score=xxxx&totalscore=xxx");
request->setResponseCallback(this,httpresponse_selector(T24HttpClient::HttpResponse));
//要对client进行release
client->release();
return true;
}
//通过回调的方式实现
void T24HttpClient::HttpResponse(CCHttpClient*client, CCHttpResponse*response)
{
if (!response->isSucceed())
{
CCLog("response error: %s",response->getErrorBuffer());
return;
}
//获得相应的数据
std::vector<char>* data =response->getResponseData();
std::string strData;

for (it = data->begin(); it != data->end(); ++it)
{

char buf[8192];
FILE* f = fopen("btn_go_0.png","rb");
int len = fread(buf,1,8192,f);
fclose(f);
CCLOG("len=%d\n",len);
req->setRequestData((const char*)buf,len);
client->send(req);
req->release();
return true;
}
void HttpClientPost::HttpResponse(CCHttpClient*client, CCHttpResponse*response)
{
//如果相应失败
if (!response->isSucceed())
{
//获取失败信息
CCLog("response error: %s",response->getErrorBuffer());
return;
}
//获得相应的数据
std::vector<char>* data =response->getResponseData();
