FastDfs示例代码

初始化

List<IPEndPoint> trackerIPs = new List<IPEndPoint>();
IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse("192.168.0.123"),22122);
trackerIPs.Add(endPoint);
ConnectionManager.Initialize(trackerIPs);
StorageNode node = FastDFSClient.GetStorageNode("group1");

获取文件信息

FDFSFileInfo fileInfo = FastDFSClient.GetFileInfo(node, fileName);
Console.WriteLine(string.Format("FileName:{0}", fileName));
Console.WriteLine(string.Format("FileSize:{0}", fileInfo.FileSize));
Console.WriteLine(string.Format("CreateTime:{0}", fileInfo.CreateTime));
Console.WriteLine(string.Format("Crc32:{0}", fileInfo.Crc32));

上传文件

byte[] buffer = FastDFSClient.DownloadFile(node, fileName, 0L, 0L);
string localName = @"D:\a.ppt";
if (fileInfo.FileSize >= 1024)//如果文件大小大于1KB  分次写入
{
FileStream fs = new FileStream(localName, FileMode.OpenOrCreate, FileAccess.Write);
//string name_ = LocalName.Substring(LocalName.LastIndexOf("\\") + 1, LocalName.Length - LocalName.LastIndexOf("\\") - 1);
long offset = 0;
long len = 1024;
while (len > 0)
{
byte[] buffer = new byte[len];
buffer = FastDFSClient.DownloadFile(node, fileName, offset, len);
fs.Write(buffer, 0, int.Parse(len.ToString()));
fs.Flush();
// setrichtext(name_ + "已经下载：" + (offset / fileInfo.FileSize) + "%");
offset = offset + len;
len = (fileInfo.FileSize - offset) >= 1024 ? 1024 : (fileInfo.FileSize - offset);
}
fs.Close();
}
else//如果文件大小小小于1KB  直接写入文件
{
byte[] buffer = new byte[fileInfo.FileSize];
buffer = FastDFSClient.DownloadFile(node, fileName);
FileStream fs = new FileStream(localName, FileMode.OpenOrCreate, FileAccess.Write);
fs.Write(buffer, 0, buffer.Length);
fs.Flush();
fs.Close();
}

删除文件

FastDFSClient.RemoveFile("group1", fileName);

　　HTTP获取文件  
1. Http流读取  

string url = "http://aa.com/da/g5/M02/0D/16/rBEDik_nOJ0IAAAAAAA_cbJCY-UAACrRgMhVLEAAD-J352.jpg";
System.Net.HttpWebRequest req = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(url);
System.Net.HttpWebResponse res = (System.Net.HttpWebResponse)req.GetResponse();
Image myImage = Image.FromStream(res.GetResponseStream());
myImage.Save("c:\\fast.jpg");//保存

>　　WebClient直接下载   


using (WebClient web = new WebClient())
{
web.DownloadFile("http://img13.360buyimg.com/da/g5/M02/0D/16/rBEDik_nOJ0IAAAAAAA_cbJCY-UAACrRgMhVLEAAD-J352.jpg", "C:\\abc.jpg");
web.DownloadFile("http://192.168.81.233/M00/00/00/wKhR6VADbNr5s7ODAAIOGO1_YmA574.jpg", "C:\\abc.jpg");
