Symbol開発でノードの選択に困るというか面倒だったりします。
取ってくるというのはちょっと違うかもです、リストから１つ使えるノードを返すが正解かな。
ユーザーに選択させずに自動でやりたいときにご利用ください。
ノードのリストは適時メンテしてください。
普通のWEBサーバーで動くようにPHPになっています。
APIとして使っても良きかと思います。

ランダムに130ミリ秒以内に応答したもの１つを返します。

Symbolでトラップなのが
/network/properties
これを返さないノードが居たりする？もう治ったのかな？忘れましたがチェックして正常な物だけ返します。

返り値はjson
{node:xym780.allnodes.me}
となります。

ダウンロード

使い方

donwloadしたnode.phpをWEBサーバーにアップロードしてください。

あとはjavasctiptなどでnode.phpにリクエストしてください。

このようにJsonとして返ります。
{node:xym780.allnodes.me}

実装サンプル

下記のWEBサーバーにアップロードしています。

https://nftdrive-explorer.info/node.php

あとは以下のように普通に取得してください。

同期処理（XHR）

最初に同期処理でもいいかも。

sample.js


var xhr = new XMLHttpRequest();
data=null;
xhr.onreadystatechange = function() {
    switch ( xhr.readyState ) {

        case 0:
            // 未初期化状態.
            break;
        case 1: 

           // データ送信中.

             console.log( 'loading...' ); 

            break;
        case 2: // 応答待ち.
             console.log( 'loaded.' );
          
    
            break;
        case 3: // データ受信中.

             console.log( 'interactive... '+xhr.responseText.length+' bytes.' );   
      
            break;
        case 4: // データ受信完了.
            if( xhr.status == 200 || xhr.status == 304 ) {
                 data = xhr.responseText; // responseXML もあり
                 console.log( 'COMPLETE! :'+data );                   

            } else {
                console.log( 'Failed. HttpStatus: '+xhr.statusText );
            }
            break;
    }
};


//

xhr.open( 'GET', 'node.php', false );
xhr.setRequestHeader( 'Content-Type', 'application/x-www-form-urlencoded' );
xhr.send();
xhr.abort(); 

console.log(data);
//{node:xym780.allnodes.me}
};

非同期（fetch）

コラのパターンも

sample.js


fetch("node.php")
  .then(response=>{
   return response.json()
})
.then(data=>{

console.log(data);
//{node:node:xym780.allnodes.me}

})

コード本体

注意点としては$symbolNodeLisの中身を適時更新してください。
これだけあれば当分ダイジョブだとは思いますが。2023.11.30現在

$symbolNodeList=[]
