Laravel从API获取数组数据存入数据库时遇属性读取错误

错误原因 #

1. 遍历对象错误：你的$responses是单个API响应的关联数组（包含status、message、consignment三个键），而非多个数据项的集合。foreach ($responses as $response)会依次遍历出200、成功提示字符串、consignment数组，当遍历到整数200时，尝试读取$response->invoice就会触发“对整数读取属性”的错误。
2. 数据访问方式错误：API返回的是数组结构，你却用了对象属性访问符->，正确的数组访问应该用['键名']，或者先将数组转为对象。

正确代码实现 #

方案一：直接使用数组索引访问（推荐） #

// 提取出需要的consignment数据
$consignment = $responses['consignment'];

$curDatains = new CurrierData();
$curDatains->orderId = 1;
$curDatains->orderInvoice = $consignment['invoice'];
$curDatains->consignment_id = $consignment['consignment_id'];
$curDatains->tracking_code = $consignment['tracking_code'];
$curDatains->status = $consignment['status'];
$curDatains->save();

方案二：将数组转为对象后访问 #

如果习惯使用对象属性的方式访问，可以先把consignment数组转为对象：

$consignment = (object)$responses['consignment'];

$curDatains = new CurrierData();
$curDatains->orderId = 1;
$curDatains->orderInvoice = $consignment->invoice;
$curDatains->consignment_id = $consignment->consignment_id;
$curDatains->tracking_code = $consignment->tracking_code;
$curDatains->status = $consignment->status;
$curDatains->save();

补充说明 #

如果后续API会返回多个consignment的集合（比如consignment是数组数组），再考虑使用foreach遍历，但当前场景下单个响应只需要提取consignment字段即可。
