Question

您好我想知道如何将我的Laravel基本Web服务连接到My Android Application？目前我尝试使用native和laravel代码。我设法从本机PHP获取json。但是当我在Laravel中尝试它时，它返回相同的json但无法在Android中接收它，错误说明了Doctype

对于我的控制器中的Laravel

    public function jsonview()
{
    $data2  =DB::table('item_list')->orderBy('id','desc')->get();
    $response = array();
    $response["status"] =1;
    $response["message"] = "getting data";
    $response["data"]=array();
    //$response["data"] = $data2;
    //or with
    foreach ($data2 as $data2) {
        $datas = array();
        //echo "lol";
        $datas["nama_item"] = $data2->nama_item;
        $datas["description"] = $data2->description;
        $datas["price"] = $data2->harga;
        $data = DB::table('users')->where("id","=",$data2->seller)->first();
        $datas["seller"] = $data->firstname;
        $datas["picture"] = $data2->pic_name;
        array_push($response["data"], $datas);
    }
    //dd(Request::json()->get('data'));

    return Response()->json(['data'=>$response["data"]]);
}

在Android中返回错误

它保持接收

Value <!DOCTYPE

这里是完整的错误代码

My Current Android适用于原生php，但尚未在Laravel中接收

这可能是因为您的代码显示错误页面。它是HTML页面，当然它在开头包含DOCTYPE。

只需检查日志中的错误并进行修复。
