file_get_contents 不是 return 一切

Question

我正在尝试 return 来自 steamcommunity 市场的完整 json 模式。不幸的是，它只是 return 第一个模式。

它应该 return : {"success":true,"lowest_price":"$0.63","volume":"5,301","median_price":"$0.68 "}

仅插入 returns {"success":true}

<?php
$hash = "AK-47 | Elite Build (Minimal Wear)";
$marketObj = json_decode(file_get_contents("http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=$hash"), true);
        if ($marketObj['success'] !== true) {
            echo jsonErr('An error occured while fetching market price for an item.');
            return;
        }else {
            echo ($marketObj['lowest_price']);
        }
?>

所以问题是我无法读取脚本中的其他参数。有人知道吗？

您需要 urlencode() 查询字符串，因为它包含特殊字符：

$hash = urlencode("AK-47 | Elite Build (Minimal Wear)");

或者，您可以这样做：

$url = 'http://steamcommunity.com/market/priceoverview/?' . http_build_query([
    'currency' => '1',
    'appid' => '730',
    'market_hash_name' => 'AK-47 | Elite Build (Minimal Wear)',
]);
$marketObj = json_decode(file_get_contents($url), true);

file_get_contents 不是 return 一切

file_get_contents doesn't return everything

php

file-get-contents

partial
