brew上怎么判断网络不通？

[p23814739]

现在在brew上做一个利用IWeb接口 发送接收数据的程序，流程是这样的：客服端post一个数据包给服务器，然后服务器收到数据包后会响应客户端一个数据包。

下面是我的源码：
int NH_GetInstallCode( )
{
CGPSApp *pMe = (CGPSApp*)GETAPPINSTANCE();
UIBOOL nRet = UIFALSE;
char szSetupNum[50]; //安装码
nRet = UI_GetInstallCode( pMe, szSetupNum, pMe->g_NavRegisterInfo.szIMEINum );
if ( nRet == UIFALSE )
{
return 0;
}
navi_memcpy( pMe->g_NavRegisterInfo.szSetupNum, szSetupNum, navi_strlen(szSetupNum) );
NavLog( "NH_GetInstallCode:[%s]\n", pMe->g_NavRegisterInfo.szSetupNum );
return 1;
}

//设置参数
int NH_AddWebOpt( )
{
CGPSApp *pMe = (CGPSApp*)GETAPPINSTANCE();
int i = 0;
int nRet = -1;
WebOpt awo[15];

if ( pMe->g_pIWeb == NULL )
return 0;
//1
awo[i].nId = WEBOPT_CONNECTTIMEOUT;
awo[i].pVal = (void *)100000;
i++;

awo[i].nId = WEBOPT_USERAGENT;
awo[i].pVal = (void *)WEBBER_USERAGENT;
i++;
//2
// awo[i].nId = WEBOPT_BODY;
// awo[i].pVal = (void *)pMe->g_pISource;
// i++;
//3
// awo[i].nId = WEBOPT_METHOD;
// awo[i].pVal = (void *)"post";
// i++;
//4
awo[i].nId = WEBOPT_HANDLERDATA;
awo[i].pVal = (void *)pMe;
i++;
//5

// i++;

// awo[i].nId = awo[i].nId = WEBOPT_STATUSHANDLER;
// awo[i].pVal = (void *)NH_WebStatus;
// i++;
//8
// awo[i].nId = WEBOPT_CONTENTLENGTH;
// awo[i].pVal = (void *)STRLEN(pMe->g_pszPostData + 1);
// i++;
//9
awo[i].nId = WEBOPT_FLAGS;
awo[i].pVal = (void *)WEBREQUEST_NOWAITCONN;
i++;
//10
awo[i].nId = WEBOPT_FLAGS;
awo[i].pVal = (void *)WEBREQUEST_FORCENEWCONN;
i++;
//11
awo[i].nId = WEBOPT_PROXYSPEC;
awo[i].pVal = (void *)"http:///";
i++;
//12
awo[i].nId = WEBOPT_PROXYSPEC;
awo[i].pVal = (void *)"*:///http://besideyou.mapabc.com:8080/navisoftware/qdactive.do";
i++;
//13
awo[i].nId = WEBOPT_END;

nRet = IWEB_AddOpt( pMe->g_pIWeb,awo);
if ( nRet == SUCCESS )
{
return 1;
}

return 0;
}

//读取服务器反馈过来的数据包
void NH_ReadFromWebCB( void *po )

CGPSApp *pMe = (CGPSApp*)po;
char szBuffer[1024] = {0};

return 0;

//设置接收响应的回调

if ( (ISource*)0 != pMe->g_pISource )

IWEB_GetResponse(pMe->g_pIWeb,
(pMe->g_pIWeb, &pMe->g_pIWebResp, &pMe->g_WebCallBack, pMe->g_pszUrl,
WEBOPT_HANDLERDATA, pMe,
WEBOPT_HEADER, "X-Method: POST\r\n", /* for kicks */
WEBOPT_HEADERHANDLER, NH_WebHeader,
WEBOPT_STATUSHANDLER, NH_WebStatus,
WEBOPT_METHOD, "POST",
WEBOPT_BODY, pMe->g_pISource,
WEBOPT_CONTENTLENGTH, STRLEN(pMe->g_pszPostData + 1),
WEBOPT_END));
}
else
{
NavLog( "URL: %s\n", pMe->g_pszUrl );

WEBOPT_HEADERHANDLER, NH_WebHeader,
WEBOPT_STATUSHANDLER, NH_WebStatus,
WEBOPT_END));
}

return 1;

}

程序调用的入口是：int NH_WebStart( )。

我遇到的问题是：
1、既然在NH_AddWebOpt( )设置了WEBOPT_CONNECTTIMEOUT参数，但是不知道在哪里判断连接超时？
2、怎么判断网络不通？？？

请大家支招，回答尽量详细，到位。。。O(∩_∩)O哈哈~ 谢谢

[nixionglin]

如果网络通 pMe->m_pWRI->nCode 返回的这个值为 200
这个值可以在回调函数里用 IWEBRESP_GetInfo(pMe->m_pIWebResp)取得
希望我的回答对你有用！

已经在真机上调试成功，希望对大家有用。。。一些函数是我项目上写的，大家可以自行去掉。
