Php 代码有但我没有'；我不知道在哪里

所以我有代码应该从bitskins或steamcommunity获取物品价格。它什么都做，除了价格是0

<?php
require_once "../config.php";
require_once "../db.php";
$secret ="";
$api = "";
require_once 'GoogleAuthenticator.php';
$ga = new PHPGangsta_GoogleAuthenticator();
$oneCode = $ga->getCode($secret);
if(!isset($_GET['secret']) || $_GET['secret'] != $config['bot_key_add']){
    die("Access denied");
    return;
}

$json = json_decode(file_get_contents("php://input"));

$weapon = urlencode($json->weapon);
$link = "https://bitskins.com/api/v1/get_item_price/?api_key=" . $api . "&code=" . $oneCode . "&names=" . $weapon . "&delimiter=!END!";
$steam_price = file_get_contents($link);
$item_price = json_decode($steam_price);
if(empty($item_price) || $item_price->success == false || empty($item_price->price))
{
    $link = "http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=.$weapon";
    $price2 = $item_price->median_price;
    $price2 = str_replace("&#36;" , "", $price2);
    $price2 = str_replace("$" , "", $price2);
    $price2 = round(str_replace(",",".",$price2), 2);
}
else 
{
    $price2 = $item_price->price;
    $price2 = str_replace("&#36;" , "", $price2);
    $price2 = str_replace("$" , "", $price2);
    $price2 = round(str_replace(",",".",$price2), 2);
}
$saveWeapon = $pdo->prepare("");

$saveWeapon->execute([  ":steamId"      => $json->userID,
                        ":classid"      => $json->classid,
                        ":assetid"      => $json->assetid,
                        ":weaponName"   => $json->weapon,
                        ":price"        => $price2,
                        ":float"        => $json->color
]);
?>

如果项位于数据库中，则以下是bitskins API结果： 如果项目不在数据库中，请执行以下操作：

基本上，若项目不在数据库中，它应该使用steam市场。我找不到任何“错误”代码，但它在数据库中插入了0。好吧，让我们看看这里发生了什么

$link = "https://bitskins.com/api/v1/get_item_price/?api_key=" . $api . "&code=" . $oneCode . "&names=" . $weapon . "&delimiter=!END!";
$steam_price = file_get_contents($link);
$item_price = json_decode($steam_price);
if(empty($item_price) || $item_price->success == false || empty($item_price->price))
{
    $link = "http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=.$weapon";
    $price2 = $item_price->median_price;
    $price2 = str_replace("$" , "", $price2);
    $price2 = str_replace("$" , "", $price2);
    $price2 = round(str_replace(",",".",$price2), 2);
}

您无法从steamcommunity.com

$link

获取内容，并试图从失败的数据集中提取

中间价

试着这样做：

$link = "https://bitskins.com/api/v1/get_item_price/?api_key=" . $api . "&code=" . $oneCode . "&names=" . $weapon . "&delimiter=!END!";
$steam_price = file_get_contents($link);
$item_price = json_decode($steam_price);
if(empty($item_price) || $item_price->success == false || empty($item_price->price))
{
    $link = "http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=.$weapon";
    // Added
    $steam_price = file_get_contents($link);
    $item_price = json_decode($steam_price);
    // 
    $price2 = $item_price->median_price;
    $price2 = str_replace("$" , "", $price2);
    $price2 = str_replace("$" , "", $price2);
    $price2 = round(str_replace(",",".",$price2), 2);
}

当bitskins上的price为null时尝试这样做，否则它会从bitskins获取price，或者我在那里做了一些错误的事情：D？您使用
文件获取内容
从bitskins.com获取数据，但如果失败，您就不能使用
文件获取内容
从backup steamcommunity.com获取数据。嗯，您能为我“修复”代码吗？非常感谢，先生添加了示例解决方案。尝试了您的部分代码，但仍在数据库中输入了0以获取价格。
