如何在PHP中通过cURL获取此节点ID?

I have some file save on unkownNodeId and only know that in range 0 to 5 http://example.com/api/node/fileId/unkownNodeId

When I send request to get fileId, for example is 2233 http://example.com/api/node/2233/unkownNodeId

I always have to try 1 by 1 like this http://example.com/api/node/2233/0 1 2 3 4 5 When I get wrong unkownNodeId, server only response as json array {"status":false} Is there anyway to send request by curl, then stop on right nodeId?

    don't think curl can do that by itself, but use a scripting language in combination with curl, it's trivial. for example with php-cli:

    php -r '$ch=curl_init();
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    for($i=0;$i<6;++$i){
        curl_setopt($ch,CURLOPT_URL,"http://example.com/api/node/2233/".$i);
        $ret=curl_exec($ch);
        if($ret!=="{\"status\":false}"){
            echo "correct node id: $i";
            return;
        }
    }'
    

    output: correct node id: 0
