我为CommandGet事件设置了一个简单的事件处理程序。
当回复使用GET方法发送的数据时,我可以解析参数并毫无问题地发送XML数据(参见下面的代码)
Download := ARequestInfo.Params.Values['dld'];
Config := ARequestInfo.Params.Values['config'];
Flash := ARequestInfo.Params.Values['flash'];
Employees := ARequestInfo.Params.Values['employees'];
Schedule := ARequestInfo.Params.Values['schedules'];
AppTables := ARequestInfo.Params.Values['apptables'];
Heartbeat := NewHeartbeat;
Heartbeat.Version.Dld := Download;
Heartbeat.Version.Config := Config;
Heartbeat.Version.Flash := Flash;
Heartbeat.Version.Employee := Employees;
Heartbeat.Version.Schedule := Schedule;
Heartbeat.Version.AppTables := AppTables;
AResponseInfo.ContentType := 'application/xml';
AResponseInfo.ResponseNo := 200;
AResponseInfo.ContentText := '<?xml version="1.0" encoding="utf-8"?>' +
#13+#10 + FormatXMLData(Heartbeat.XML);
XMLDocument1.xml.Clear;
XMLDocument1.Active := True;
XMLDocument1.XML.text := ARequestInfo.FormParams;
SynMemo1.Lines.Add(ARequestInfo.FormParams);
SynMemo1.Lines.Add(#13+#10);
if XMLDocument1.XML.Count > 0 then
begin
XMLDocument1.XML.Delete(0);
XMLDocument1.XML.Delete(0);
for i := pred(xmldocument1.xml.count) downto 0 do
begin
stmp := XMLDocument1.XML.Strings[i];
if Length(stmp) > 0 then
begin
if Copy(stmp,1,1) = '<' then
break
else
XMLDocument1.XML.Delete(i);
end
else
XMLDocument1.XML.Delete(i);
end;
XMLDocument1.XML.Text := StringReplace(XMLDocument1.XML.Text,
'<Punches ', '<Punches xmlns="http://ats/punch" ', [rfReplaceAll]);
end;
Punch := GetPunches(XMLDocument1);
PunchReply := NewOperationStatus;
PunchReply.Uid := Punch.Uid;
PunchReply.NodeValue := 'OK';
stmp := '<?xml version="1.0" encoding="utf-8"?>' +
#13+#10 + FormatXMLData(PunchReply.XML);
SynMemo1.Lines.Add(stmp);
SynMemo1.Lines.Add(#13+#10);
AResponseInfo.ContentType := 'text/html';
AResponseInfo.ContentStream := TStringStream.Create(stmp);
我用wireshark来查看发生了什么,看起来indy在发送响应之前发送了一个ACK,导致客户端断开连接。
任何关于如何解决这个问题的建议,我都会回复POST数据并获取。
