delphi 之 get post

没测试过这个

var
     Source:   TMemoryStream;
     Response:   TStringStream   ;
 begin
 try
         //   Set   the   properties   for   HTTP
         idHTTP.Request.Username   :=   'www ';
         idHTTP.Request.Password   :=   'www ';
 //         idHTTP1.Request.ProxyServer   :=   '11.133.190.13 ';
 //         idHTTP1.Request.ProxyPort   :=   StrToIntDef( '80 ',   80);
         idHTTP.Request.ContentType   :=   'application/x-www-form-urlencoded ';
           Response   :=   TStringStream.Create( ' ');
             try
                     Source   :=   TMemoryStream.Create;
                     try
                         Source.LoadFromFile( 'unsub.xml ');   //发送这个XML包，反向取消请求
                         idHTTP.Post( 'http://222.333.444.555/dsmp/dsmp.wsdl ',   Source,   Response);
                     finally
                       //   Source.Free;
                     end; 

                 memo.Lines.Text   :=   Response.DataString;//返回的字串,可以把它存为XML就可以
                 memo.Lines.SaveToFile( 'unsubresp.xml ');         //返回的反向取消应答包
             finally
                 Response.Free;
             end;
     finally
     end

这个方法试了 可以用

以下仅供参考，要求在web页面写特殊的字符，根据返回的结果判断是否登陆成功，用户名，密码方式见下：

procedure   TForm1.Button1Click(Sender:   TObject);
 var
     Url:   string;
     Response   :   TStringStream;
     Request   :   TStrings;
 begin
     Memo1.Clear;
     Response   :=   TStringStream.Create( ' ');
     try
         Request   :=   TStringList.Create;
         try
             Request.Append( 'txtUserId=hengli&txtPassword=ysj);
             url   :=   'http://192.168.1.33/nmmis/index.aspx ';
             IdHTTP1.Request.ContentType   :=   'application/x-www-form-urlencoded ';
             IdHTTP1.Post(Url,   Request,   Response);
             Memo1.Lines.Text   :=   Response.DataString;
         finally
             FreeAndNil(Request);
         end;
     finally
         FreeAndNil(Response);
     end;
 end;

通过idhttp上传文件到web上，然后返回上传的文件路径。

function   UpLoagFile(FileName:   String):   string;
 var
     obj   :   TIdMultiPartFormDataStream;
     Url:   String;
 begin
     obj   :=   TIdMultiPartFormDataStream.Create;
     try
         obj.AddFile( 'Image ',FileName,   GetMIMETypeFromFile(FileName));
         http.Request.ContentType   :=   obj.RequestContentType;
         obj.Position   :=   0;
         Url   :=     'http://192.168.1.44/insertImage.aspx ';
         Result   :=   http.Post(Url,   obj);
     finally
         obj.Free;
     end;
 end; 

 服务端,C#:
 private   void   Page_Load(object   sender,   System.EventArgs   e)
 {
         foreach(string   f   in   Request.Files.AllKeys)
         {
                 string   fileName,   fullName;
                 HttpPostedFile   postFile   =   Request.Files[f];
                 if   (postFile.ContentLength   >   10)
                 {
       fileName   =   postFile.FileName;
       //GetFileName(   fileName,   out   fullName   );
       fullName   =   "UpLoad/aaa.jpg "
       postFile.SaveAs   (   Server.MapPath   (   fullName   )   );
       Response.Write   (fullName);
 }
         }
 }
