获取网络时间、解析xml、截取string

很多游戏具有每日登陆奖励功能，为防止玩家修改本地时间，需要读取服务器时间。下面分两部分介绍获取网络时间的两种方法，第一部分解析xml，第二部分截取string。

第一部分：通过国家授时中心链接获得的数据如下:

然后解析xml获得当前时间,完整代码如下：

01	using UnityEngine;
02	using System.Collections;
03	using System.Xml;
04
05	/// <summary>
06	/// Get web time and parse xml
07	/// 获取网络时间/解析xml
08	/// </summary>
09	public class Test1 : MonoBehaviour
10	{
11	public string timeURL = "http://www.time.ac.cn/timeflash.asp?user=flash";//授时中心地址
12	// Use this for initialization
13	void Start()
14	{
15	StartCoroutine(GetTime());
16	}
17
18	IEnumerator GetTime()
19	{
20	Debug.Log("Start get web time");
21	WWW www = new WWW(timeURL);
22	while (!www.isDone)
23	{
24	Debug.Log("Getting web time");
25	yield return www;
26	Debug.Log("Finish getting web time and whole xml is : " + www.text);
27	ParseXml(www);
28	}
29	}
30
31	public void ParseXml(WWW www)
32	{
33	XmlDocument xmlDoc = new XmlDocument();
34	xmlDoc.LoadXml(www.text);
35	XmlElement root = xmlDoc.DocumentElement;
36	XmlNodeList nodeList = root.SelectNodes("/ntsc/time");
37	foreach (XmlElement xe in nodeList)
38	{ //Unity3D教程手册：www.unitymanual.com
39	foreach (XmlElement x1 in xe.ChildNodes)
40	{
41	if (x1.Name == "year")
42	Debug.Log("Current year: " + x1.InnerText);
43	if (x1.Name == "month")
44	Debug.Log("Current month: " + x1.InnerText);
45	if (x1.Name == "day")
46	Debug.Log("Current day: " + x1.InnerText);
47	if (x1.Name == "hour")
48	Debug.Log("Current hour: " + x1.InnerText);
49	if (x1.Name == "minite")
50	Debug.Log("Current minite: " + x1.InnerText);
51	if (x1.Name == "second")
52	Debug.Log("Current second: " + x1.InnerText);
53	}
54	}
55	}
56	}

获得的网络时间如下:

获取网络时间、解析xml、截取string

第二部分:通过北京时间链接地址获得的数据如下:

1	t0=new Date().getTime(); nyear=2013; nmonth=6; nday=3; nwday=1; nhrs=16; nmin=57; nsec=29;

然后截取string获得网络时间,具体方法是截取“;”获得年月日...然后截取“=”获得对应的时间.

完整代码如下:

01	using UnityEngine;
02	using System.Collections;
03
04	/// <summary>
05	/// Get web time and split string
06	/// 获取网络时间/截取string
07	/// </summary>
08	public class Test2 : MonoBehaviour
09	{
10	public string timeURL = "http://www.beijing-time.org/time.asp";//北京时间地址
11	// Use this for initialization
12	void Start()
13	{
14	StartCoroutine(GetTime());
15	}
16
17	IEnumerator GetTime()
18	{
19	Debug.Log("Start get web time");
20	WWW www = new WWW(timeURL);
21	while (!www.isDone)
22	{ //Unity3D教程手册：www.unitymanual.com
23	Debug.Log("Getting web time");
24	yield return www;
25	Debug.Log("Finish getting web time and whole xml is : " + www.text);
26	SplitString(www);
27	}
28	}
29
30	public void SplitString(WWW www)
31	{
32	string[] timeData = www.text.Split(';');
33	for (int i = 0; i < timeData.Length; i++)
34	{
35	string[] exactTime = timeData[i].Split('=');
36	foreach (string temp in exactTime)
37	Debug.Log(temp);
38	}
39	}
40	}
