电商数据查询API如何用PHP进行调用？构建商品信息、价格监控、评论分析等作用

一、科技应用背景

在电商行业快速发展的今天，数据驱动决策已成为企业运营的核心竞争力。通过API接口获取电商平台数据，能够为企业提供以下核心价值：

• 市场洞察：实时掌握商品价格和销量趋势

• 竞品分析：监控竞争对手商品策略变化

• 用户研究：分析商品评论挖掘用户需求

• 运营优化：基于数据优化商品标题和详情页

二、PHP实现完整代码

// 探数API客户端
$apiKey = 'https://www.tanshuapi.com/market/detail-128';
$ecommerceApi = new EcommerceDataApi($apiKey);
// 示例1：获取商品详情
$itemId = '123456789';
$result = $ecommerceApi->getItemDetail($itemId);
if (isset($result['error'])) {
    echo "查询失败: " . $result['error'];
} else {
    // 创建商品信息对象
    $itemInfo = new EcommerceDataApi::ItemInfo();
    foreach ($result as $key => $value) {
        if (property_exists($itemInfo, $key)) {
            $itemInfo->$key = $value;
        }
    }
    // 输出商品信息
    echo "商品ID: " . $itemInfo->item_id . "\n";
    echo "商品标题: " . $itemInfo->title . "\n";
    echo "当前价格: " . $itemInfo->price . "元\n";
    echo "原价: " . $itemInfo->original_price . "元\n";
    echo "折扣: " . $itemInfo->getDiscount() . "%\n";
    echo "月销量: " . $itemInfo->sales . "\n";
    echo "店铺名称: " . $itemInfo->shop_name . "\n";
    echo "商品主图: " . $itemInfo->getMainImage() . "\n";
    // 业务处理
    if ($itemInfo->getDiscount() > 20) {
        echo "⚠️ 商品正在大促，建议关注竞品价格\n";
    }
}
// 示例2：获取商品评论
$comments = $ecommerceApi->getItemComments($itemId, 1, 5);
if (isset($comments['error'])) {
    echo "获取评论失败: " . $comments['error'];
} else {
    echo "\n商品评论(最新5条):\n";
    foreach ($comments['list'] as $comment) {
        $commentInfo = new EcommerceDataApi::CommentInfo();
        foreach ($comment as $key => $value) {
            if (property_exists($commentInfo, $key)) {
                $commentInfo->$key = $value;
            }
        }
        echo "用户: " . $commentInfo->user_nick . "\n";
        echo "评分: " . str_repeat('★', $commentInfo->score) . "\n";
        echo "内容: " . $commentInfo->content . "\n";
        echo "时间: " . $commentInfo->getFormattedTime() . "\n";
        echo "----------------\n";
    }
    // 分析评论情感
    $sentiment = $this->analyzeCommentsSentiment($comments['list']);
    echo "评论情感分析: " . $sentiment['summary'] . "\n";
}
/**
 * 简单评论情感分析
 */
private function analyzeCommentsSentiment($comments) {
    $positive = 0;
    $negative = 0;
    $neutral = 0;
    foreach ($comments as $comment) {
        if ($comment['score'] >= 4) {
            $positive++;
        } elseif ($comment['score'] <= 2) {
            $negative++;
        } else {
            $neutral++;
        }
    }
    $total = count($comments);
    return [
        'positive' => $positive,
        'negative' => $negative,
        'neutral' => $neutral,
        'positive_rate' => $total > 0 ? round($positive / $total * 100, 1) : 0,
        'summary' => $positive > $negative ? '好评为主' : ($negative > $positive ? '差评较多' : '评价中性')
    ];
