js 单利的使用方法:
httpUtils.getInstance().httpPost('http://192.168.1.107:8081/index.php?s=/app/verify/sendverify.html', params, function (data) { if (data === -1) { cc.log('请检查网络!'); } else { var jsonD = JSON.parse(data); if (jsonD['status'] === 1) { cc.log('发送成功'); } else { cc.log('发送失败' + ':' + eval("'" + jsonD['message'] + "'"));
}
}
});
