最近、signalR 0.5.3 から 1.0.x rc2 にアップグレード/アップグレードしていますが、接続の作成に問題があります。
問題は、私が例外に遭遇していることです:
TypeError: res が null です
connection.appRelativeUrl = res.Url;
接続を作成するスクリプトは、デフォルトのデモ コードに戻されています。
var connection = $.connection('/signalr');
connection.start(function () {
console.log("connection started!");
});
それでもエラーが発生します。jquery.signalr.js ファイルにステップ インし、接続コードをヒットすると、次のようになります。
var url = connection.url + "/negotiate";
connection.log("Negotiating with '" + url + "'.");
$.ajax({
url: url,
global: false,
cache: false,
type: "GET",
data: {},
dataType: connection.ajaxDataType,
error: function (error) {
$(connection).triggerHandler(events.onError, [error.responseText]);
deferred.reject("SignalR: Error during negotiation request: " + error.responseText);
// Stop the connection if negotiate failed
connection.stop();
},
success: function (res) {
var keepAliveData = connection.keepAliveData;
connection.appRelativeUrl = res.Url;
最後の行に到達しましたが、 res パラメーターが null であり、接続の試行を爆破しています。すべての signalR 依存関係を更新し、ハブで追加のクライアント/サーバー プロパティを使用するようにすべてのハブ クライアント側呼び出しを変更しました。
私の /signalr/hubs js スクリプトが作成されており、利用できると予想されるサーバー側のハブ メソッドにマッピングされたすべての適切なメソッドが含まれています。js ファイルは次のとおりです。
