Wie kann ich die Voted-Ereignisse von TheDAO abrufen?

Pablo Jabo · Answer 1

Vielen Dank @BokkyPooBah für die allgemeine Idee, aber der endgültige Code unterscheidet sich ein wenig von dem, was Sie geschrieben haben. Der Prototyp zum Abonnieren eines Ereignisses in Solidität ist (ich verwende web3):

SolidityEvent.prototype.execute = function (indexed, options, callback)

Also wird der erste Parameter indiziert, dem ich ein leeres Objekt übergebe. Der Optionsparameter sollte die Blockinformationen wie folgt haben:

var theDAOInterfaceABI = [{ "constant": true, "inputs": [{ "name": "", "type": "uint256" }], "name": "proposals", "outputs": [{ "name": "recipient", "type": "address" }, { "name": "amount", "type":

Es funktioniert perfekt, es ruft alle Ereignisse aus dem angegebenen Blockintervall ab (hier ab Block 1594771 bis spätestens).

@Pablo Yabo, ich habe versucht, Ihren geänderten Code zu verwenden, bekomme die Ereignisse aber immer noch nicht konsistent. Könnten Sie bitte die vollständigen Anweisungen hinzufügen, die Sie verwenden, einschließlich einiger Beispielausgaben. Vielen Dank.
Überprüfen Sie den neuen Code, er war unvollständig. Jetzt habe ich das Ganze in der Geth-Konsole getestet und dort die gleiche Ausgabe erhalten.
Wie könnte ich das Erhalten der Ausgabe ignorieren { callbacks: filterId: ... watch: function(callback) }und nur die Protokolle erhalten. @Pablo Yabo

Filtern von Ereignissen

Hier ist die DAOInterface.VotedEreignisdefinition von EtherScan.io - The DAO - Source Code :

event Voted(uint indexed proposalID, bool position, address indexed voter);

Und hier ist ein Beispiel für Befehle, die die Felder voterund proposalIDverwenden, um nach bestimmten Ereignissen zu filtern:

// Find all Voted events from one address
var theDAOVotedEvent = theDAO.Voted({voter: "0x8063379a7bf2cb923a84c5093e68dac7f75481c5"}, {fromBlock: 1614771, toBlock: 'latest'});
theDAOVotedEvent.watch(function(error, result){
  console.log(JSON.stringify(result));
});

Bezug

Von der JavaScript-API - web3.eth.filter :

Objekt - Ein Filterobjekt mit den folgenden Methoden:

filter.get(callback): Gibt alle Protokolleinträge zurück, die dem Filter entsprechen.

filter.watch(callback): Überwacht Statusänderungen, die zum Filter passen, und ruft den Callback auf. Einzelheiten finden Sie in diesem Hinweis.

filter.stopWatching()**: **Stoppt die Überwachung und deinstalliert den Filter im Knoten. Sollte immer angerufen werden, wenn es fertig ist.

Vielen Dank für den Code. Mit diesem Code bekomme ich die neuen Stimmen, aber ich bekomme die neuen nicht. Wenn Sie in der Antwort sehen, dass es heißt: fromBlock: undefined, to: undefined, toBlock: undefined
Sie bekommen die neuen Stimmen, aber nicht die alten Stimmen? Versuchen Sie, den fromBlockParameter einzustellen.
Ich habe es getan, ich habe 0, 1000000, 1600000 und mehr ausprobiert, aber es heißt immer toBlock: undefined und es werden nur neue Stimmen gemeldet. Irgendwelche Ideen?
Ich habe versucht zu verwenden get(), konnte aber die Ergebnisse nicht zurückbekommen. Wenn ich es schaffe, werde ich diese Seite aktualisieren.

Wie kann ich die Voted-Ereignisse von TheDAO abrufen?
