我正在尝试处理我的api中的一些错误。但是，我尝试了许多方法来执行所需的操作？

在代码中，我使用了Exception \ Exception，这是另一个扩展到Exception的类“ use \ Exception”。这些选项均无效。我需要执行块捕获吗？

  //Piece of source in the begin of file
    namespace Business\Notifiers\Webhook;
    use \Exception;
    class MyException extends \Exception {}

    //Piece of source from my class
    try{

        $products = $payment->getProducts();
        if(count($products) == 0)
            return;
        $flight_id = $products[0]->flight_id;
        $this->message = 'Sir, we have a new request: ';
        $products = null; //Chagind it to null to force an error..
        foreach($products as $product){

            $this->appendAttachment(array(
                'color' => '#432789',
                'text' => 
                    "*Name:* $product->name $product->last_name \n" . 
                    "*Total Paid:*  R\$$product->price\n",
                'mrkdwn_in' => …

我究竟做错了什么？？

我正在尝试任何方式来获取POST数据但总是不起作用.那么它如何为null执行第一个condional响应就是badRequest("Expceting some data").

路线

POST   /pedidos/novo    controllers.Pedidos.cadastraPedidoNoBanco

我的控制器中的动作

@BodyParser.Of(BodyParser.Json.class)
    public static Result cadastraPedidoNoBanco(){
        JsonNode data = request().body().asJson();
        if(data == null){
            return badRequest("Expceting some data");
        } else {
            return ok(data);
        }
    }

另一个失败测试

所以这没有发生任何错误,但我不知道为什么响应是这样的:

资源

public static Result cadastraPedidoNoBanco(){
    Map<String,String[]> data = request().body().asFormUrlEncoded();
    if(data == null){
        return badRequest("Expceting some data");
    } else {
        String response = "";
        for(Map.Entry value : data.entrySet()){
            response += "\n" + value.getValue();
        }
        return ok(response);
    }
}
