39行代码为:  $item=$resp["item_list"]['sp_item'][0];
-----------------------------------------------------------------------------------------------------------------------------

错误提示为:

com.caucho.quercus.QuercusErrorException: E:\TAE_SVN\TAE_SDK\apps\ceshi7\admin\core\GoodsCreate.php:39: Fatal Error: Can't use object 'stdClass' as array

-----------------------------------------------------------------------------------------------------------
前后代码为:


if ($dopost == 'caiji')
{
    if ($numIid != "" && rRuleNum($numIid))
    {
        $c = new TopClient;
        $c->appkey = $appkey;     //top appkey
        $c->secretKey = $secretKey;  //top secretkey
        //实例化具体API对应的Request类
        $req = new SpItemInfoListGetRequest;
$req->setId($numIid);
$req->setSiteKey('3zzd10741k7259kez673850e4346d6l1');
$resp = $c->execute($req);

//print_r($resp);

$item=$resp["item_list"]['sp_item'][0];

        if ($item)
        {
            $detail_url = $item["item_url"];   //商品链接
            $num_iid = $item["item_id"];        //商品ID
            $title = $item["title"];           //商品标题
            $nick = $item["nick"];            //卖家昵称
            $pic_url = "http://img1.tbcdn.cn/tfscom/".$item["pic_url"];      //商品主图
            
            $price = $item["price"];       //商品原价格
           // $freight_payer = $item["freight_payer"]; //取消了
            $freight_payer ="seller";//临时都设置为包邮

$sid=$item["seller_id"]; //卖家数字ID

            $num = 1000;            //商品数量 临时使用
            $item_imgs =$item["itemImgs"];       //商品图片列表
        }
        else
            $createMessage = '不存在这个商品';
        //print_r($resp);
    }
    else
    {
        $createMessage = "商品ID【不能为空】并且【必须是数字】。";
    }
}

------解决思路----------------------
年轻人,想当然是大忌!
楼主只有
$resp = $c->execute($req);
//print_r($resp);
$item=$resp["item_list"]['sp_item'][0];
并没有给出 print_r($resp) 的结果
你如何就能断定他就是 json 解码的结果呢?
我用 json 模拟一个出错的场景,并不表示是楼主的真实情况
只是说明这种错误可能在什么情况下出现

况且我也说了原因:你是把对象当做数组访问了

我在帮楼主分析出错的原因,你捣什么乱

Quote: 引用:


$o = json_decode('{"a":{"b":[1,2,3]}}');
echo $o['a']['b'][0];
报错 Fatal error:  Cannot use object of type stdClass as array 

可推知你是把对象当做数组访问了
要这样
echo $o->a->b[0];


也可这样
$o = json_decode('{"a":{"b":[1,2,3]}}',true);
echo $o['a']['b'][0];



这个你也没说原因。。。。。。。

应该是 json_decode  总是返回一个PHP对象   而不是数组
