JSON-Abfrage mit Indy-Komponenten

[tkoenig]

Malzeug zusammen,

Ich versuche zur Zeit, mich ein wenig mit Delphi-Programmierung und Internet. Als kleines Test-Projekt will ich jetzt sozusagen eine automatisierte Datenbank mit Auswertungen über meinen World of Tanks Clan basteln. Erster Schritt ist das Auslesen der Mitglieder. Diese finde ich auf http://worldoftanks.eu/community/clans/500010608-G0LD/ unten in der Tabelle. Diese Seite abzufragen ist mit idHTTP kein Problem, funktioniert auch wunderbar. Das Problem ist die eigentliche Tabelle.

Diese wird durch eine separate Abfrage mit JSON-Daten gefüllt. Ich habe diese JSON-Abfrage mit Fiddler mitgeschnitten und versuche nun, sie nachzubauen:

Delphi-Quellcode:

procedure TForm1.InitHTTP;
begin
  clan_request := TIdHTTP.Create(nil);
  clan_request.AllowCookies := true;
  clan_request.CookieManager := IdCookieManager1;
  clan_request.Request.Accept := 'application/json, text/javascript, */*; q=0.01';
  clan_request.Request.AcceptEncoding := 'gzip, deflate';
  clan_request.Request.AcceptLanguage := 'de-de,de;q=0.8,en-us;q=0.5,en;q=0.3';
  clan_request.Request.UserAgent := 'Mozilla/5.0 (Windows NT 5.1; rv:14.0) Gecko/20100101 Firefox/14.0.1';
  clan_request.Request.Connection := 'keep-alive';
end;

function TForm1.GetClanMembers: string;
var url: string;
begin
  clan_request.Request.Referer := 'http://worldoftanks.eu/community/clans/500010608-G0LD/';
  url := 'http://worldoftanks.eu/community/clans/500010608/members/?type=table&_=1343897160069&offset=0&limit=100&order_by=date&search=&echo=1&id=clan_members_index';

  result := clan_Request.Get(url);
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  InitHTTP;
  Memo1.Text := GetClanMembers;
end;

Wenn ich das ganze jetzt ausführe, bekomme ich von den Indy-Komponenten den schicken 404-Fehler, die selbe Abfrage in Firefox bringt ebenfalls 404.




Das ist die Abfrage mit Fiddler im Firefox mitgeschnitten:

Code:

GET /community/clans/500010608/members/?type=table&_=1343897160069&offset=0&limit=100&order_by=date&search=&echo=1&id=clan_members_index HTTP/1.1

Accept-Language: de-de,de;q=0.8,en-us;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate

Und das die Response:

Mich interessieren wirklich nur die JSON-Daten, was kann ich noch tun? Hat es vielleicht was mit den Cookies zu tun? Ich bin für jede Hilfe dankbar.

Zitat von tkoenig:

Hat es vielleicht was mit den Cookies zu tun?

Ja, erst muss der Client auf eine Seite zugreifen die ihm die Sessioncookies in der HTTP Antwort mitsendet (z.B. eine Loginseite).

Indy speichert die Cookies im Cookiemanager und sendet sie bei der HTTP Anfrage auf die API-URL dann mit.

[tkoenig]

Danke für die schnelle Antwort. Habe mal fix nachgeschaut. Der wichtige Cookie (csrftoken) wird bei Aufruf der eigentlichen Seite gesetzt, Aufruf dieser Seite vorher bringt aber auch nichts, Fehler 404 bleibt der selbe

Edit: Problem gelöst, es lag an dem Header "X-Requested-With: XMLHttpRequest"
clan_request.Request.CustomHeaders.Add('X-Requested-With: XMLHttpRequest'); hat zumindest den 404-Fehler behoben.
