EOFError: 通过 Savon ruby​​ 客户端调用 SOAP API 到达文件末尾

Question

提到的错误来自在防火墙后面调用 API，但我正在尝试从 EngineYard 实例访问 API。 EngineYard 实例 IP 在其防火墙中列入白名单。

client = Savon.client(wsdl: "https://amagentostore.com/api/v2_soap?wsdl", read_timeout: 300, follow_redirects: true)
products = client.
          call(:dcapimodule_product_list, message: { session_id: session_id, additional_attributes: @additional_attributes }).
          body[:dcapimodule_product_list_response][:products][:item]

我收到以下错误

有什么想法吗？

Answer 1

问题是 @additional_attributes 是 nil，而 WSDL 需要一个数组。
