SOAP, WSDL未知输入/输出

我正在尝试使用以下WSDL文件创建SOAP服务器

    </wsdl:service>
</wsdl:definitions>

但我们从来没有我试着得到

Array
(
    [0] => UNKNOWN AddProduct(UNKNOWN $parameters)
)
Array
(
    [0] => struct AddProductRequest {
 Product Product;
}
    [1] => struct Product {
 integer quantity;
 string itemName;
 string URL;
 float pricePerItem;
 integer categoryId;
 string color;
 string size;
 float domesticShippingAndTaxes;
}
    [2] => struct AddProductResponse {
 boolean HasErrors;
 string error;
}
)

我尝试了几次更改，但仍然出现未知的东西，我也尝试了不同的解决方案，同样的情况下没有成功
