如何获得工作线程阵列？找不到我的错误我是新手

Question

无法解码 JSON 以 foreach 需要帮助

<?php 
$workers      = 'https://api.ethermine.org/miner/***/workers';
$workersContent = file_get_contents($workers);
$workersJson = json_decode($workersContent, true);
foreach ($workersJson['data']['worker'] as $worker) {
    $output = $worker['worker'][1]; 
     echo $output;
 }

?>

如何获得工作线程阵列？找不到我的错误我是新手 ☺

Answer 1

访问网址时，我可以看到结构是这样的：

{"status":"OK","data":[{"worker":"gtx1050tix4","time":1520599200,"lastSeen":1520599074,"reportedHashrate":45518082,"currentHashrate":43333333.333333336,"validShares":39,"invalidShares":0,"staleShares":0,"averageHashrate":43559413.580246896}]}

如果你想得到gtx1050tix4那么答案是

foreach ($workersJson['data']['worker'] as $worker) {
    $output = $worker; 
    echo $output;

}

如果你想从那里获得整个数据和输出，答案是

    foreach ($workersJson['data'] as $data) {
        $worker = $data['worker'];
        $time = $data['time']; // any key from json

       echo $worker;

}

希望这能为您清除问题

请试试这个：

<?php 
$workers      = 'https://api.ethermine.org/miner/YOURAPIKEY/workers';
$workersContent = file_get_contents($workers);
$workersJson = json_decode($workersContent, true);
//print_r($workersJson);
foreach ($workersJson['data'] as $worker) {
    $output = $worker['worker']; 
     echo $output;
 }
?>

你可以执行以下操作：

$workers        = 'https://api.ethermine.org/miner/YOURAPIKEY/workers';
$workersContent = file_get_contents($workers);
$workersJson    = json_decode($workersContent, true);
foreach ($workersJson['data'] as $worker) {
    //$worker["worker"] <-- accessing gtx1050tix4
    //$worker["time"] <-- accessing 1520599200
    //etc
    echo "<pre>";
    print_r( $worker );
    echo "</pre>";
}

这将导致：

Array
(
    [worker] => gtx1050tix4
    [time] => 1520599200
    [lastSeen] => 1520599074
    [reportedHashrate] => 45518082
    [currentHashrate] => 43333333.333333
    [validShares] => 39
    [invalidShares] => 0
    [staleShares] => 0
    [averageHashrate] => 43559413.580247
)
