1.通過http協議，post同時上傳多張圖片和資料到伺服器上。
2.IOS開發中前端採用xcode 7.1 swift語言。
3.伺服器端採用asp.net，asp實現。

一、下面先看看前端程式碼。
1.先把需要上傳的圖片存在img陣列中。
2.imgs為圖片數量，names和context為需要上傳的資料。
上傳圖片swift程式碼：

 func upload(img:[UIImage])
     {
        let context = mytext.text
        let names : String = self.title! as String
        lb.frame
 
=CGRectMake(0,250, self.view.bounds.size.width,20)
        lb.textColor=UIColor.whiteColor()
        lb.text="上傳中...."
        lb.textAlignment=NSTextAlignment.Center
        lb.backgroundColor=UIColor.blackColor()
        lb.alpha=1
        //新增風火輪
        av.frame=CGRectMake(100,280,20, 20)
        av.backgroundColor
 
=UIColor.whiteColor()
        av.color=UIColor.redColor()
        av.startAnimating()
         self.view.addSubview(av)
         self.view.addSubview(lb)
        var data:[NSData] = [UIImagePNGRepresentation(img[0])!]
        for (var i = 1; i < imgs; ++i) {
           data += [UIImagePNGRepresentation(img[i])! as NSData]
      }
         let uploadurl:String="http://192.168.2.66:81/uploadpic.aspx?id="
 
+names+"&context="+context
        //設定伺服器接收地址
        let request=NSMutableURLRequest(URL:NSURL(string: uploadurl)!)
          request.HTTPMethod="POST"//設定請求方式
         let body=NSMutableData()
         let boundary:String="---------------------------7d33a816d302b6"
         let contentType:String="multipart/form-data;boundary="+boundary
          request.addValue(contentType, forHTTPHeaderField:"Content-Type")
        //傳圖片
        for (var k = 0; k < imgs; ++k) {
        body.appendData(NSString(format:"\r\n--\(boundary)\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
        body.appendData(NSString(format:"Content-Disposition:form-data;name=\"userfile1\";filename=\"dd1.jpg\"\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
        body.appendData(NSString(format:"Content-Type:image/jpeg\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
        body.appendData(data[k])
        }
        body.appendData(NSString(format:"\r\n--\(boundary)--\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
        request.HTTPBody=body
         let que=NSOperationQueue()
         NSURLConnection.sendAsynchronousRequest(request, queue: que, completionHandler: {
            (Response, data, error) -> Void in
            if (error != nil){
                 print(error)
             }else{
                 let tr:String=NSString(data:data!,encoding:NSUTF8StringEncoding)! as String
                  print(tr)
                   //在主執行緒中更新UI風火輪才停止
                  dispatch_sync(dispatch_get_main_queue(), {
                  self.av.stopAnimating()
                 self.lb.hidden=true
                })
             }
         })
    }

二、伺服器端實現程式碼。
1、資料庫，用來儲存上傳的資料和圖片路徑。
context(
[ID] [int] IDENTITY(1,1) NOT NULL,
[nosn] varchar NULL,
[context] varchar NULL,
[createtime] varchar NULL,
[img1] varchar NULL,
[img2] varchar NULL,
[img3] varchar NULL,
[img4] varchar NULL
）
2､接收上傳多張圖片的程式碼：uploadpic.aspx

<%@ Page language="c#" AutoEventWireup="false"  %> 
<%
string names = Request.QueryString["id"];
string ctxt = Request.QueryString["context"];
string spath = Server.MapPath("/"+names);
string SaveFilePath ="";
string[] sfpath =new string[4];
int rq = Request.Files.Count;
Response.Write(rq);
if (System.IO.Directory.Exists(spath) == false)
{
System.IO.DirectoryInfo dirinfo = System.IO.Directory.CreateDirectory(spath);
}
int i=0;
for (i=0; i<=rq-1; i++ ) {
    sfpath[i] = "/"+names+"/"+System.DateTime.Now.ToString("yyyymmddhhmmssfff") + i+".jpg";
 SaveFilePath = Server.MapPath(sfpath[i]);
HttpPostedFile postfile1=Request.Files[i];
postfile1.SaveAs(SaveFilePath);
}
Response.Write(rq + "  image upload success!\r\n");
string url = "http://192.168.2.66:81/postcontext.asp?id="+ names + "&context=" + ctxt + "&img1="+sfpath[0] +"&img2="+sfpath[1] +"&img3="+sfpath[2] +"&img4="+sfpath[3];
//string data = "id="+ names + "&context=" + ctxt + "&img1="+sfpath1 +"&img2="+sfpath2 +"&img3="+sfpath3 +"&img4="+sfpath4;
string data = "";
Response.Write (data);
 try
{
byte[] postBytes = Encoding.GetEncoding("utf-8").GetBytes(data);
System.Net.HttpWebRequest myRequest = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url);
myRequest.Method = "POST";
myRequest.ContentType = "text/html";
myRequest.ContentLength = postBytes.Length;
myRequest.Proxy = null;
System.IO.Stream newStream = myRequest.GetRequestStream();
newStream.Write(postBytes, 0, postBytes.Length);
newStream.Close();
// Get response
System.Net.HttpWebResponse myResponse = (System.Net.HttpWebResponse)myRequest.GetResponse();
using (System.IO.StreamReader reader = new System.IO.StreamReader(myResponse.GetResponseStream(), Encoding.GetEncoding("utf-8")))
{
string content = reader.ReadToEnd();
Response.Write( content);
}
}
catch (System.Exception ex)
{
Response.Write( ex.Message);
}
 Response.End();
%>

3.儲存資料的檔案：postcontext.asp

<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<!-- #include file="conn.asp" --> 
<%
dim id,mys
urls="http://192.168.2.66:81"
id = Request.QueryString("id")

mys = request.QueryString("context")
img1 = request.QueryString("img1")
img2 = request.QueryString("img2")
img3 = request.QueryString("img3")
img4 = request.QueryString("img4")
if img1<> "" then
   img1 = urls & img1
 end if 

if img2<> "" then
   img2 = urls & img2
 end if 
 if img3<> "" then
   img3 = urls & img3
 end if 
 if img4<> "" then
   img4 = urls & img4
 end if 
 dim rs1
sqlcmd="insert into context (nosn,context,createtime,img1,img2,img3,img4) VALUES  ('"&id&"','"&mys&"',getdate(),'"&img1&"','"&img2&"','"&img3&"','"&img4&"') "
set rs1=conn.execute(sqlcmd)  
response.Write(sqlcmd)
Response.write "儲存成功！"
  %>
