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　　

 /// <summary> /// 文件上传配置项 /// </summary> public class FileUploadConst {  /// <summary>  /// 上传地址  /// </summary>  public string UploadPath { get; set; }  /// <summary>  /// 文件访问/下载地址  /// </summary>  public string DownloadPath { get; set; }  /// <summary>  /// 访问共享目录用户名  /// </summary>  public string UserName { get; set; }  /// <summary>  /// 访问共享目录密码  /// </summary>  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<FileUploadConst>(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<FileUploadConst> 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

  /// <summary>  /// 连接远程共享文件夹  /// </summary>  /// <param name="path">远程共享文件夹的路径</param>  /// <param name="userName">用户名</param>  /// <param name="passWord">密码</param>  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

  /// <summary>  /// 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  /// </summary>  /// <param name="inFileStream">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"</param>  /// <param name="dst">保存文件的路径，不含名称及扩展名</param>  /// <param name="fileName">保存文件的名称以及扩展名</param>  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

  /// <summary>  /// 上传附件到文件服务器中  /// </summary>  [HttpPost, Route("api/Upload/UploadAttachment")]  [AllowAnonymous]  public ServiceResponse<UploadRespModel> 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<UploadRespModel>.SuccessResponse(msg, viewModel, code);  }

4.图片地址拼接方法

  /// <summary>  /// 拼接文件全路径  /// </summary>  /// <param name="filePath">文件相对地址</param>  private string GetFileFullPath(string filePath)  {   var str = string.Empty;   if (!string.IsNullOrEmpty(filePath))   {    // 兼容旧数据    if (filePath.Contains("") || filePath.Contains("https://"))    {     str = filePath;    }    else    {     var host = FileUploadConfig.DownloadPath;     str = $"{host}/{filePath}";    }   }   return str;  }
