Ruby Rails 中使用 Savon 的 SOAP 调用在信封和主要操作周围变得奇怪
SOAP call in Ruby on Rails using Savon gets weird around the envelope and main operation
在使用 Savon.rb 的 rails 项目中，我正在尝试进行非常复杂的 SOAP 调用。至少复杂到 Savon 建设者遇到很多麻烦的程度，所以我决定直接操纵 :xml。
首先我启动客户端：
@client = Savon.client(
:endpoint => 'https://testservice.postnl.com/CIF_SB/BarcodeWebService/1_1/BarcodeWebService.svc',
:wsdl => 'https://testservice.postnl.com/CIF_SB/BarcodeWebService/1_1/?wsdl')
然后我以以下形式进行调用：
@request = @client.build_request(:generate_barcode,
xml: %Q{ ... see soap call (with ruby interpolation) ... }
我添加了一个格式正确的 l Time.now, format: :postnl_api 字符串，其余的仍然是硬编码的。包括消息编号。
以下是 Savon 在这种情况下实际调用的方式，使用 @request.body 检索。

似乎不对劲的主要事情（顺便说一句，使用 Savon 构建器也是如此）是 envelope 的属性和主要操作的 :generate_barcode 形状及其属性。我不明白为什么我在 GenerateBarcode.
之前得到前缀 wsdl:
我告诉 Savon 拿走我的 xml 并完全按照那样建造它，但它不起作用。按原样发送我的版本 returns 错误 400。
