Question

我现在已经有这个问题了一段时间，但我一直在缩小这个问题，我认为我现在已经找到了主要问题。虽然我的JSONstore正确调用了PHP，并且firebug确实从数据库中返回了正确的数据，但它不会显示在我的网格中。

我有一个只有2列日期的网格，以及来自日志的条目。当我取出日志条目时，网格将显示日期正常，当我刚刚从日志创建一个包含静态数据的数组时，它也将在网格中正常显示。我认为我的JSONstore没有正确地从mysql表中解析数据。

我的代码是：

  var logStore = new Ext.data.JsonStore({
    autoLoad: true,
    url: 'inc/interface/config.php?list=messages',
    root: 'dates',
    idProperty: 'ID',
    fields: ['ID', 'ReceivedAt', 'Message'],
    listeners: {
                loadexception: function() {
                    console.log('load failed -- arguments: %o', arguments);
                }
        }
}); 

  var logGrid = new Ext.grid.GridPanel({
        region: 'center',
        store: logStore,
        colModel: new Ext.grid.ColumnModel({
            columns: [{
                id: 'received',
                header: 'Received',
                dataIndex: 'ReceivedAt',
                width: 250
            },{
                id: 'message',
                header: 'Logs',
                dataIndex: 'Message',
                width: 750
            }]
        })
    });

它所提取的日志条目的一个例子是：

| Apr 9 00:00:02 dh1 dhcpd: Added new forward map from nfxxxxich-PC.wifi-uhs.osu to 10.xxx.xx.248 |
| Apr 9 00:00:02 dh1 dhcpd: added reverse map from 248.xxxx.xxx.10.in-addr.arpa. to nxxxxxh-PC.wifi-uhs.osu |
| Apr 9 00:00:02 dh1 dhcpd: DHCPREQUEST for 10.xxx.xxx.248 from 00:x:5c:x:8c:xx (nxxxxh-PC) via 10.xxx.xxx.254 |
| Apr 9 00:00:02 dh1 dhcpd: DHCPACK on 10.X.XX.248 to 00:X:5c:X8c:XX (nXXXich-PC) via 10.193.XX.XXX |
| Apr 9 00:00:02 dh1 dhcpd: Added new forward map from XX.wifi-uhs.XXX to 10.X.X.242 |
| Apr 9 00:00:02 dh1 dhcpd: added reverse map from 242.X.193.X.in-addr.arpa. to X.wifi-uhs.XXX |
| Apr 9 00:00:02 dh1 dhcpd: DHCPREQUEST for 10.X.X.242 from 00:X:ce:X21:63 (elena) via 10.X.X.254 |
| Apr 9 00:00:02 dh1 dhcpd: DHCPACK on 10.193.XXX.XX to 00:X:ce:X:21:63 (elena) via 10.X.X.254 |
| Apr 9 00:00:02 dh1 dhcpd: Added new forward map from P305-XXX.wifi-uhs.XXX to 10.193.X.X |
| Apr 9 00:00:02 dh1 dhcpd: added reverse map from 21.241.X.X.in-addr.arpa. to P305-XXXX.wifi-uhs.XXX |

日期，dh1和日志条目本身之间有各种不同的字符和制表符。逃避这些角色会有问题吗？我只是不太确定它是如何完成的。任何帮助，将不胜感激。

Answer 1

您尚未在字段中指定类型和格式。而且我猜你的php json实现不会生成javascript Date对象。

所以...尝试返回一个unix时间戳并将其用作字段：

fields: [
  {name: 'ID', type: 'int'},
  {name: 'ReceivedAt', type: 'date', dateFormat: 'Y-m-d H:i:s'},
  'Message'
]

您也可以选择在dateFormat旁边指定type: 'date'。有关详细信息，请参阅文档：http://www.sencha.com/deploy/dev/docs/?class=Ext.data.Field

{"dates":[{"ID":"18","ReceivedAt":"2010-07-07 11:37:42","Message":"Apr  9 00:00:03 dh1 dhcpd: added reverse map from 244.xxx.xxx.10.in-addr.arpa. to xxx.wifi-uhs.xxx"},{"ID":"19","ReceivedAt":"2010-07-07 11:37:42","Message":"Apr  9 00:00:03 dh1 dhcpd: DHCPREQUEST for 10.xxx.xxx.244 from 00:xx:f0:xx:d5:xxx (xxx) via xx.x.xxx.254"},{"ID":"20","ReceivedAt":"2010-07-07 11:37:42","Message":" [origin software="rsyslogd" swVersion="3.22.1" x-pid="5222" x-info="http://www.rsyslog.com"] (re)start"},{"ID":"21","ReceivedAt":"2010-07-07 11:37:42","Message":"WARNING: rsyslogd is running in compatibility mode.

We suggest upgrading your config and adding -c3 as the first rsyslogd option."},{"ID":"22","ReceivedAt":"2010-07-07 11:37:42","Message":"the last error occured in /etc/rsyslog.conf, line 38"},{"ID":"23","ReceivedAt":"2010-07-07 11:37:42","Message":"warning: selector line without actions will be discarded"},{"ID":"24","ReceivedAt":"2010-07-07 11:37:42","Message":"CONFIG ERROR: could not interpret master config file '/etc/rsyslog.conf'. [try http://www.rsyslog.com/e/2123 ]"},{"ID":"25","ReceivedAt":"2010-07-07 11:37:42","Message":"Warning: backward compatibility layer added to following directive to rsyslog.conf: ModLoad imuxsock"}]}

实际上我发现了问题，而不是我的代码。我限制我的PHP仅提取19条记录并且它有效，它在第20条记录中，我得到一种不同类型的日志，它在我的网格上混乱，什么都不会显示。我认为它与日志中的特殊字符有关。

无论哪种方式，Rsyslog都是一个错误，我正在使用它将这些转储到mysql中。我不确定如何通过php / extjs修复它。
