本文介绍了使用Multipart表单数据进行文件上载的Web服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我面临着如何使用多部分表单数据使用TransferFile（）方法的Web服务的关键问题？ 我已经为它编写了以下代码： [WebMethod] [ScriptMethod（ResponseFormat = ResponseFormat.Json）] public void TransferFile（） { HttpContext postedContext = HttpContext.Current; HttpFileCollection Request = postingContext.Request.Files; foreach （HttpPostedFile item in Request） { string filename = item.FileName; byte [] fileBytes = new 字节 [item.ContentLength]; item.InputStream.Read（fileBytes， 0 ，item.ContentLength）; TransferFile（filename，fileBytes）; // objFileTransfer.TransferFile（filename，fileBytes）; retJSON = js.Serialize（ new {Result = objFileTransfer.TransferFile（filename，fileBytes）}）; Context.Response.Write（retJSON）; // fileBytes现在包含文件内容 // 文件名包含文件名 } } 这个网络服务是否获得多部分表单数据？ 当iPhone开发人员使用此API时，他们没有得到回复。 private FtpWebRequest ftpRequest = null ; // private FtpWebResponse ftpResponse = null; private 流ftpStream = null ; private int bufferSize = 2048 ; public string TransferFile（ string filename， byte [] fileContent） { string strMsg = string .Empty; 尝试 { / * 创建FTP请求* / 字符串 uploadUrl = 字符串 .Format（ {0} / {1} / {2}， ftp：// Address， DirectoryName，filename）; ftpRequest =（FtpWebRequest）FtpWebRequest.Create（uploadUrl）; / * 使用提供的用户名和密码登录FTP服务器* / ftpRequest.Credentials = new NetworkCredential（ 用户名， 密码）; / * 如有疑问，请使用以下选项* / ftpRequest.UseBinary = true ; ftpRequest.UsePassive = true ; ftpRequest.KeepAlive = true ; / * 指定FTP请求的类型* / ftpRequest.Method = WebRequestMethods.Ftp.UploadFile; 尝试 { ftpRequest.ContentLength = fileContent.Length; 流requestStream = ftpRequest.GetRequestStream（）; requestStream.Write（fileContent， 0 ，fileContent.Length）; requestStream.Close（）; FtpWebResponse response =（FtpWebResponse）ftpRequest.GetResponse（）; strMsg = 文件上传状态： + response.ToString（）; } catch （Exception ex）{Console.WriteLine（ex.ToString（））; } / * 资源清理* / ftpStream.Close（）; ftpRequest = null ; } catch （Exception ex）{Console.WriteLine（ex.ToString（））; } return strMsg; } 解决方案 Hello Rajesh， 以下是示例代码。当点击提交按钮时，它会将所选文件数据发布到提到的（动作）网站。 < 表单 id = Form1 action = htt：//mysite.com/photo 方法 = post enctype = multipart / form-data > < 输入 id = myPhoto name = myPhoto type = file / > < input type = 提交 / > < / form > 谢谢， Imdadhusen 请检查答案 - WCF服务接受邮政编码的multipart / form-data [ ^ ]。 这可能对你有帮助。 I am facing critical problem that How to make webservice that uses TransferFile() method by multipart form data?.I have write following code for it:[WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public void TransferFile() { HttpContext postedContext = HttpContext.Current; HttpFileCollection Request = postedContext.Request.Files; foreach (HttpPostedFile item in Request) { string filename = item.FileName; byte[] fileBytes = new byte[item.ContentLength]; item.InputStream.Read(fileBytes, 0, item.ContentLength); TransferFile(filename, fileBytes); //objFileTransfer.TransferFile(filename, fileBytes); retJSON = js.Serialize(new { Result = objFileTransfer.TransferFile(filename, fileBytes) }); Context.Response.Write(retJSON); // fileBytes now contains the content of the file // filename contains the name of the file } }Is this webservice get multipart form data?When an iPhone developer consume this api they are not getting response.private FtpWebRequest ftpRequest = null; //private FtpWebResponse ftpResponse = null; private Stream ftpStream = null; private int bufferSize = 2048; public string TransferFile(string filename, byte[] fileContent) { string strMsg = string.Empty; try { /* Create an FTP Request */ String uploadUrl = String.Format("{0}/{1}/{2}", "ftp://Address", "DirectoryName", filename); ftpRequest = (FtpWebRequest)FtpWebRequest.Create(uploadUrl); /* Log in to the FTP Server with the User Name and Password Provided */ ftpRequest.Credentials = new NetworkCredential("Username", "Password"); /* When in doubt, use these options */ ftpRequest.UseBinary = true; ftpRequest.UsePassive = true; ftpRequest.KeepAlive = true; /* Specify the Type of FTP Request */ ftpRequest.Method = WebRequestMethods.Ftp.UploadFile; try { ftpRequest.ContentLength = fileContent.Length; Stream requestStream = ftpRequest.GetRequestStream(); requestStream.Write(fileContent, 0, fileContent.Length); requestStream.Close(); FtpWebResponse response = (FtpWebResponse)ftpRequest.GetResponse(); strMsg = "File Upload Status: " + response.ToString(); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } /* Resource Cleanup */ ftpStream.Close(); ftpRequest = null; } catch (Exception ex) { Console.WriteLine(ex.ToString()); } return strMsg; } 解决方案 Hello Rajesh,Following are sample code. When clicking on submit button it will post selected files data to the mentioned (action) website.<form id="Form1" action="htt://mysite.com/photo" method="post" enctype="multipart/form-data"> <input id="myPhoto" name="myPhoto" type="file" /> <input type="submit" /></form>Thanks,ImdadhusenPlease check the answer - WCF service to accept a post encoded multipart/form-data[^].This might help you. 这篇关于使用Multipart表单数据进行文件上载的Web服务的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
