C# 从带有php头位置的URL获取文件名
我有一个网站在php这段代码C# 从带有php头位置的URL获取文件名,c#,C#,我有一个网站在php这段代码 switch($type){ case 'check': switch($action){ case 'update': echo "1.0.0.1"; break; } break; case 'download': $file = './ss/godzila.avi'; if (file_exis
switch($type){
case 'check':
switch($action){
case 'update':
echo "1.0.0.1";
break;
}
break;
case 'download':
$file = './ss/godzila.avi';
if (file_exists($file)) {
header("Location: {$file}");
exit;
}else{
header("HTTP/1.0 404 Not Found");
}
break;
}
我是如何把c转换成文件名的?此文件仅用于测试。我将从更新服务器发送软件更新
我需要c中的文件名:
FileStream newFile = new FileStream(filePatch+fileName, FileMode.Create);
newFile.Write(downloadedData, 0, downloadedData.Length);
下载文件时,您只需检查HttpWebResponse.Headers,它们应该包含您发送的标题 我想你可以举一个例子,我根据你的具体用途对它做了一些修改nl:你需要得到的文件名
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
namespace wget
{
class Program
{
static bool DownloadFile(string url, string targetDirectory, out string realFilename, string defaultName = "unknown.txt")
{
// first set the filename to a non existing filename
realFilename = string.Empty;
bool succes = false;
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = WebRequestMethods.Http.Get;
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
if (response.Headers.HasKeys())
{
/* in case no header found that is called "Location" you get your default set filename as a fallback */
realFilename = Path.Combine(targetDirectory, response.Headers["Location"] ?? defaultName);
}
else
{
realFilename = Path.Combine(targetDirectory, defaultName);
}
using (Stream responseStream = response.GetResponseStream())
{
int blockSize = 8192;
byte[] buffer = new byte[blockSize];
int result;
if (!Directory.Exists(targetDirectory))
{
Directory.CreateDirectory(targetDirectory);
}
using (FileStream targetStream = new FileStream(realFilename, FileMode.Create, FileAccess.Write))
{
do
{
result = responseStream.Read(buffer, 0, buffer.Length);
targetStream.Write(buffer, 0, result);
} while (result > 0);
}
}
}
succes = true;
}
catch (WebException wex)
{
if (wex.Response != null)
{
wex.Response.Close();
}
Console.WriteLine("WebException occured: {0}", wex.Message);
}
catch (FileNotFoundException fnfe)
{
Console.WriteLine("FileNotFoundException occured: {0} not found! {1}", fnfe.FileName, fnfe.Message);
}
catch (Exception ex)
{
Console.WriteLine("Error occured: {0}", ex.Message);
}
return succes;
}
static void Main(string[] args)
{
string filename;
if (DownloadFile("http://www.google.com", Environment.CurrentDirectory, out filename))
{
Console.WriteLine("Saved file to {0}", filename);
}
else
{
Console.WriteLine("Couldn't download file!");
}
Console.ReadLine();
}
}
}
你的意思是,你想从某个服务器下载文件?是的,我从许可证/更新服务器下载文件,文件名在标题中?这里是php代码。。标题位置…我下载文件,但需要文件名才能将filestream写入硬盘
