创建共享文件夹参考资料：https://www.cnblogs.com/dansediao/p/5712657.html
一、配置上传文件相关参数并读取参数
1.配置appsettings.json
{
"FileUploadInfo": {
"UploadPath": "\\\\172.21.0.10\\File",
"DownloadPath": "http://213.10.11.126:8001/",
"UserName": "ShareUser",
"Password": "Password"
}
}
2.读取配置数据
2.1 新建实体类
///
/// 文件上传配置项
///
public class FileUploadConst
{
///
/// 上传地址
///
public string UploadPath { get; set; }
///
/// 文件访问/下载地址
///
public string DownloadPath { get; set; }
///
/// 访问共享目录用户名
///
public string UserName { get; set; }
///
/// 访问共享目录密码
///
public string Password { get; set; }
}
2.2 映射实体类与配置项
在startup.cs中配置
public void ConfigureServices(IServiceCollection services)
{
services.Configure(Configuration.GetSection("FileUploadInfo"));
}
3.控制器中读取配置项，通过注入的方式
public FileUploadConst FileUploadConfig { get; set; }
public UploadController(IOptions option)
{
FileUploadConfig = option.Value;
}
二、上传文件
上传文件之前记得初始化构造方法，注入文件上传配置项！！！！！↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑
1.连接文件服务器方法
///
/// 连接远程共享文件夹
///
/// 远程共享文件夹的路径
/// 用户名
/// 密码
private static bool connectState(string path, string userName, string passWord)
{
var flag = false;
var proc = new Process();
try
{
proc.StartInfo.FileName = "cmd.exe";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.CreateNoWindow = true;
proc.Start();
var dosLine = "net use " + path + " " + passWord + " /user:" + userName;
proc.StandardInput.WriteLine(dosLine);
proc.StandardInput.WriteLine("exit");
while (!proc.HasExited)
{
proc.WaitForExit(1000);
}
var errormsg = proc.StandardError.ReadToEnd();
proc.StandardError.Close();if (string.IsNullOrEmpty(errormsg))
{
flag = true;
}
else
{
throw new Exception(errormsg);
}
}
catch (Exception ex)
{
WriteHelper.WriteFile(ex);
throw ex;
}
finally
{
proc.Close();
proc.Dispose();
}
return flag;
}
2.传输文件流到服务器中
///
/// 向远程文件夹保存本地内容，或者从远程文件夹下载文件到本地
///
/// 要保存的文件的路径，如果保存文件到共享文件夹，这个路径就是本地文件路径如：@"D:\1.avi"
/// 保存文件的路径，不含名称及扩展名
/// 保存文件的名称以及扩展名
private static void Transport(Stream inFileStream, string dst, string fileName)
{if (!Directory.Exists(dst))
{
Directory.CreateDirectory(dst);
}
dst = dst + fileName;
if (!System.IO.File.Exists(dst))
{var outFileStream = new FileStream(dst, FileMode.Create, FileAccess.Write);
var buf = new byte[inFileStream.Length];
int byteCount;
while ((byteCount = inFileStream.Read(buf, 0, buf.Length)) > 0)
{
outFileStream.Write(buf, 0, byteCount);
}
inFileStream.Flush();
inFileStream.Close();
outFileStream.Flush();
outFileStream.Close();
}
}
3.接收文件并上传到文件服务器
///
/// 上传附件到文件服务器中
///
[HttpPost, Route("api/Upload/UploadAttachment")]
[AllowAnonymous]
public ServiceResponse UploadAttachment()
{
var viewModel = new UploadRespModel();
var code = 200;
var msg = "上传失败!";
var path = FileUploadConfig.UploadPath; //@"\\172.16.10.130\Resource";
var s = connectState(path, FileUploadConfig.UserName, FileUploadConfig.Password);
try
{
if (s)
{
var filelist = HttpContext.Request.Form.Files;
if (filelist.Count > 0)
{
var file = filelist[0];
var fileName = file.FileName;
var blobName = FileHelper.GetSaveFolder(fileName);
path = $@"{path}\{blobName}\";
fileName = $"{DateTime.Now:yyyyMMddHHmmss}{fileName}";
//共享文件夹的目录
var theFolder = new DirectoryInfo(path);
var remotePath = theFolder.ToString();
Transport(file.OpenReadStream(), remotePath, fileName);
viewModel.SaveUrl = $"{blobName}/{fileName}";
viewModel.DownloadUrl = GetFileFullPath(viewModel.SaveUrl);
msg = "上传成功";
}
}
else
{
code = CommonConst.Code_OprateError;
msg = "链接服务器失败";
}
}
catch (Exception e)
{
Console.WriteLine(e);
msg = e.Message;
}
return ServiceResponse.SuccessResponse(msg, viewModel, code);
}
4.图片地址拼接方法
///
/// 拼接文件全路径
///
/// 文件相对地址
private string GetFileFullPath(string filePath)
{
var str = string.Empty;
if (!string.IsNullOrEmpty(filePath))
{
// 兼容旧数据
if (filePath.Contains("http://") || filePath.Contains("https://"))
{
str = filePath;
}
else
{
var host = FileUploadConfig.DownloadPath;
str = $"{host}/{filePath}";
}
}
return str;
}
