Apply post to send and receive XML files and parameters in ASP. Go

you can use post to send requests to other pages and get the results returned. You can send a post to another page from one page, or you can use HttpRequest to send a post to a page in a WinForm project. Let's take an example from an ASPX page of ASP. Post.aspx from an ASPX page, sending a request to the Receive.aspx page. 1first, build the project, add two pages, post.aspx and receive.aspx put a button in the Post page, and in its click Method we can write a piece of code like this:Private voidButton1_Click (Objectsender, System.EventArgs e) {//XML file path  stringXMLfileName = Server.MapPath ("File/frame.xml"); HttpWebRequest req=NULL; Try   {    //set the URL of the page to post to, here the Chinese parameters or have special symbols, to be encoded.    stringURL ="http://localhost/Receive.aspx"+"? Dwgfilename="+httputility.urlencode ("nnn+10111452505252706++2.bmp,nnn+10111457375757706++13.bmp")+"&pltfilename="+httputility.urlencode ("nnn+10110934363434706++ home page. JPG"); //Create a HttpWebRequest objectreq =(HttpWebRequest) httpwebrequest.create (URL); //set the way it submits data postReq. Method ="POST"; //set the value of the Content-type HTTP headerReq. ContentType ="Text/xml";//"application/x-www-form-urlencoded;charset=gb2312";       using(StreamWriter Requestwriter =NewStreamWriter (req. GetRequestStream ())) {//defines a StreamReader object that reads the contents of an XML fileStreamReader reader =NewStreamReader (XMLfileName); stringRET =Reader.     ReadToEnd (); Reader.     Close (); Requestwriter.writeline (ret);//writes the read content to the Requeststream. } Response.Write ("sent to the"); }   Catch(Exception ex) {Throwex; }   finally{     }}2. Take a look at the receive page receive.aspx the request to receive a post from the Pageload method in the Receive.aspx page. Private voidPage_Load (Objectsender, System.EventArgs e) {   if(Request.requesttype = ="POST")   {    //Response.ContentType = "Text/xml";    stringPltfilename = request.querystring["Pltfilename"];//plt file name    stringDwgfilename = request.querystring["Dwgfilename"];//DWG file Name list: 111.dwg,222.dwg,333.dwg .....//receives and reads the XML file stream from the post.StreamReader reader =NewStreamReader (Request.inputstream); String XmlData=Reader.        ReadToEnd (); Try    {     //declares a xmldoc document object, LOAD () XML stringXmlDocument doc =NewXmlDocument (); Doc.     LOADXML (XmlData); //get the XML document root nodeXmlElement root =Doc.     DocumentElement; ..... Do your own work on the XML ... }
