使用 php 和 api 显示 Steam 库存

Question

当我查询http://api.steampowered.com/IEconItems_{appid}/GetPlayerItems/v0001/?key={apikey}&steamid={steamid}&format=json时，我得到一个json响应

但问题是，如果没有任何我在任何地方都找不到的附加信息，我不知道如何处理此响应。我在查看我自己的 cs:go 库存时得到的部分响应：

                }
            ]

        }

id与武器的对应关系以及稀有性和数量也很有意义。但是我不能指望手动找到每个州每种武器的每个 ID 对吗？我是否错过了一个不同的 API，我可以使用它来查看什么武器对应什么 id？

ps: 抱歉英语不好

Answer 1

尝试将 JSON 字符串解析为数组。因为这个响应不是一个有效的 JSON 字符串，所以尝试将它插入一个新数组来解析一个有效的 JSON 字符串。

如：{"main_container": [ --> 你的发布代码]}

<?php

    $jsonResponse = '{"main_container": [
                {
                "id": 235322185,
                "original_id": 190991409,
                "defindex": 19,
                "level": 1,
                "quality": 4,
                "inventory": 70,
                "quantity": 1,
                "rarity": 4,
                "attributes": [
                    {

                "quality": 4,
                "inventory": 77,

                        "defindex": 7,
                        "value": 1141712676,
                        "float_value": 564.611572265625
                    },
                    {
                        "defindex": 8,

                    }

            }
        ]}
    ';

    $jsonDecodeArray = json_decode($jsonResponse, true);

    foreach($jsonDecodeArray as $mainContainerItems){

        // LOOP THROUGH ALL ITEM GROUP. IN THIS CASE WE HAVE 3 ITEM GROUPS IN
        // $mainContainerItems ARRAY

        foreach($mainContainerItems as $inventoryItem){

            echo $inventoryItem['id']; // will return for example: 236529059
            echo $inventoryItem['original_id']; // will return for example: 136971214
            echo $inventoryItem['defindex'];
        }       
    }
?>

在这种情况下，结果将是一个多维数组，您可以在其中循环使用多个 foreach。

结果是：

$jsonDecodeArray 包含包含所有项目的 ma​​in_container 数组，其中单个项目也是一个数组。

$inventoryItem 包含单个项目及其所有属性。如下图。

Array

    [id] => 236529059
    [original_id] => 136971214
    [defindex] => 35
    [level] => 1
    [quality] => 4
    [inventory] => 77
    [quantity] => 1
    [rarity] => 2
    [attributes] => Array
        (
            [0] => Array
                (

                    [float_value] => 3
                )

                    [float_value] => 564.61157226562
                )

                )

        )

Answer 2

您将致电GetSchema 以确定这些是哪些项目。您将 DefIndex 值与 GetSchema 返回的值进行比较

您的工作流程将如下所示：

• 调用GetSchema 并将result['items'] 的结果存储在某个地方以便以后查找
• 调用当前调用并解析项目。对于每个项目，从上方查找您的储值结果
• GetSchema 还具有您可能需要的稀有度和其他值（即那些属性）

Answer 3

将您的库存defindex（不是属性）值与此架构进行比较。

http://api.steampowered.com/IEconItems_730/GetSchema/v0002/?key=xxxxx

例如，defindex = 19 是架构上的 Weapon_p90。
