【问题描述】：

我收到了来自 API 端点的数组请求并尝试保存到数据库，但它正在将所有数组请求正文保存到每个列表中。

下面是每个列的数组发布

s:284:"{"TransactionType":"Pay
Bill","TransID":"MBL51H83P1","TransTime":"20201603457857","TransAmount":"100","BusinessShortCode":"600000","BillRefNumber":"EDSJH90","InvoiceNumber":"1232","OrgAccountBalance":"500","MSISDN":"254710306000","FirstName":"D","MiddleName":"TANUI","LastName":"KIP"}";

Laravel 函数接收请求

$data = json_decode($request->getContent() );
            $mydata= serialize(json_encode($data));
            $trn = new MpesaTransaction;
            $trn->TransactionType = $mydata;
            $trn->TransID = $mydata;
            $trn->TransTime = $mydata;
            $trn->TransAmount = $mydata;
            $trn->BusinessShortCode = $mydata;
            $trn->BillRefNumber = $mydata;
            $trn->InvoiceNumber = $mydata;
            $trn->OrgAccountBalance = $mydata;
            $trn->MSISDN = $mydata;
            $trn->FirstName = $mydata;
            $trn->MiddleName = $mydata;
            $trn->LastName = $mydata;
            $trn->save();

现在如何将每个数组值保存到其各自的列？

【解决方案1】：

如果您确定响应包含您表中的所有列，那么您可以简单地在模型上使用create 方法：

$data = json_decode($request->getContent(), true);

MpesaTransaction::unguarded(static function() use ($data) {
    MpesaTransaction::create($data);
});

否则，必须一一设置参数：

$model = new MpesaTransaction;
$model->TransactionType = $data['TransactionType'];
// ........
$model->save();

【解决方案2】：

您的代码错误。如果 $request->getContent() 是 json 那么你需要解码为数组。您可以使用我的代码进行测试。

$data = json_decode($request->getContent(),true );
$trn = new MpesaTransaction;
$trn->TransactionType = $data['TransactionType'];
$trn->TransID =  $data['TransID'];
$trn->TransTime =  $data['TransTime'];
$trn->TransAmount =  $data['TransAmount'];
$trn->BusinessShortCode =  $data['BusinessShortCode'];
$trn->BillRefNumber =  $data['BillRefNumber'];
$trn->InvoiceNumber =  $data['InvoiceNumber'];
$trn->OrgAccountBalance =  $data['OrgAccountBalance'];
$trn->MSISDN =  $data['MSISDN'];
$trn->FirstName =  $data['FirstName'];
$trn->MiddleName =  $data['MiddleName'];
$trn->LastName =  $data['LastName'];
$trn->save();
