Question

无法弄清楚为什么这个网络服务不起作用。只是给我空白。我测试了网址和数据。

http://onleague.stormrise.pt:8031/OnLeagueRest/resources/onleague/News/News?id_user=a7664093-502e-4d2b-bf30-25a2b26d6021&page=1&new_filter=0

我的代码：

session_start();
function getNews() {
    $json = file_get_contents('http://onleague.stormrise.pt:8031/OnLeagueRest/resources/onleague/News/News?id_user=a7664093-502e-4d2b-bf30-25a2b26d6021&page=1&new_filter=0');
    $data = json_decode($json, TRUE);
    $newst = array(); 
    foreach($data['data']['item'] as $item) {
        $newst[] = $item;
    }
    foreach($newst as $v) 
    {
        $_SESSION['newsid'][] = $v['id'];
        $_SESSION['newstitle'][] = $v['title'];
        $_SESSION['newstext'][] = $v['news'];
        $_SESSION['newslink'][] = $v['link'];
        $_SESSION['newsdate'][] = $v['date'];
        $_SESSION['newsentityName'][] = $v['entityName'];
        $_SESSION['aclikes'][] = $v['account']['likes'] . ")";
        $_SESSION['acdislikes'][] = $v['account']['dislikes'] . ")";
        $_SESSION['accomentes'][] = $v['account']['commentes'] . ")";
        $_SESSION['acshares'][] = $v['account']['shares'] . ")";
        $_SESSION['acclicks'][] = $v['account']['clicks'] . ")";
    }

}
getNews();
$key = count($_SESSION['newsid']);
    for ($i = 0; $i <= $key; $i++) {
        echo $_SESSION['newsid'][$i] . "<br />";
    }

你确定这条线是正确的：

foreach($data['data']['item'] as $item) {
    $newst[] = $item;
}

阅读本文让我觉得你用一个项目覆盖整个$ newstst数组......每个项目。因此，数组最终将成为 last $项的值（可能为空）。我期待的是：

foreach($data['data']['item'] as $item) {
    $newst.push( $item );
}

（注意，没有经过测试，我的语法可能很狡猾......但是你得到了漂移）。

为什么我无法从此Web服务数组中获取值？
