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
/// <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("http://") || filePath.Contains("https://")) { str = filePath; } else { var host = FileUploadConfig.DownloadPath; str = $"{host}/{filePath}"; } } return str; }
