unity3d 通过 http网络下载到本地
最近研究了下http 从服务器下载到本地。
有点复杂，没太搞明白 post， 不过也做了个demo......
用到了 2种方式 ：
1, http get
2, www
第一种：
http get
string urlPath = "http://www........";//写个网络资源路径（自己写）
string localPath = @"D:\BianZhen.mov";
///
/// 下载文件
///
IEnumerator DownLoadFile(string url)
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
request.Method= "GET";
HttpWebResponse hw = (HttpWebResponse)request.GetResponse();
Stream stream =hw.GetResponseStream();
FileStream fileStream = new FileStream(localPath, FileMode.Create, FileAccess.Write);
long length = hw.ContentLength;
long currentNum = 0;
decimal currentProgress = 0;
while (currentNum < length)
{
byte[] buffer = new byte[1024];
currentNum += stream.Read(buffer, 0, buffer.Length);
fileStream.Write(buffer, 0, buffer.Length);
if (currentNum % 1024 == 0)
{
currentProgress = Math.Round(Convert.ToDecimal(Convert.ToDouble(currentNum) / Convert.ToDouble(length) * 100), 4);
Debug.Log("当前下载文件大小:" + length.ToString() + "字节 当前下载大小:" + currentNum + "字节 下载进度" + currentProgress.ToString() + "%");
}
else
{
Debug.Log("当前下载文件大小:" + length.ToString() + "字节 当前下载大小:" + currentNum + "字节"+ "字节 下载进度" + 100 + "%");
}
currentnn = currentProgress;
yield return false;
}
hw.Close();
stream.Close();
fileStream.Close();
}
decimal currentNumShow;
GUIStyle guistyle = new GUIStyle();
void OnGUI()
{
guistyle.fontSize = 80;
GUI.Label(new Rect(50, 50, 50, 50),currentNumShow.ToString(), guistyle);
}
第二种：
www
string urlPath = "http://www.....";//资源网络路径(自己写)
string file_SaveUrl = @"D:\test.rar";//资源保路径
FileInfo file;
void Start ()
{
file = new FileInfo(file_SaveUrl);
Debug.Log(file_SaveUrl);
StartCoroutine(DownFile(urlPath));
}
///
/// 下载文件
///
IEnumerator DownFile(string url)
{
WWW www = new WWW(url);
yield return www;
if (www.isDone)
{
Debug.Log("下载完成");
byte[] bytes = www.bytes;
CreatFile(bytes);
}
}
///
/// 创建文件
///
///
void CreatFile(byte[] bytes)
{
Stream stream;
stream =file.Create();
stream.Write(bytes, 0, bytes.Length);
stream.Close();
stream.Dispose();
}
