无效的SOAP请求需要有经验的眼睛

savon wsdl soap xml ruby

TLDR:可以找到解决方案 here

我正在使用 savon 对SOAP服务发出请求。我知道。。。总的

不管怎样,我很难让Savon规矩点。SOAP提供程序具有 this validator,它接受以下输入:

Web Service: ProductData
Version: 1.0.0
Operation: getProductSellable
Endpoint: https://psproductdata100-stg.pcna.online

使用验证器时,输入以下xml:

<GetProductSellableRequest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/">
  <wsVersion xmlns="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/">1.0.0</wsVersion>
</GetProductSellableRequest>

我得到了这个反应体

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header />
  <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <GetProductSellableResponse xmlns="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/">
      <ErrorMessage xmlns="http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/">
        <code>110</code>
        <description>Authentication Credentials Required</description>
      </ErrorMessage>
    </GetProductSellableResponse>
  </s:Body>
</s:Envelope>

这个回答是有效的,因为我没有提供我的un/pw。如果我提供了凭据,我会得到完整的响应。下面是我的浏览器中发生的情况的屏幕截图。

然而,当我使用Savon提出同样的请求时

#!/usr/bin/env ruby

require 'savon'
require 'awesome_print'
require 'byebug'
require 'pry'

endpoint = 'https://psproductdata100-stg.pcna.online'
path = 'psProductData.svc?singleWsdl'
wsdl = "#{endpoint}/#{path}"

args = {
  wsdl: wsdl,
  log: true,
  log_level: :debug,
  pretty_print_xml: true,
  element_form_default: :qualified
}

client = Savon.client(args) do
  convert_request_keys_to :lower_camelcase
end

message = { ws_version: '1.0.0' }
response = client.call(:get_product_sellable) do
  message(message)
end

ap response

响应没有按预期返回。XML看起来关验证程序发送的内容,但不准确。

这是请求

      <tns:wsVersion>1.0.0</tns:wsVersion>

</env:Envelope>

以及回应

        <description>Version mismatch.</description>
      </ErrorMessage>
    </GetProductSellableResponse>
  </s:Body>
</s:Envelope>

以及Savon的输出

    :get_product_sellable_response => {
        :error_message => {
                   :code => "110",

多亏了这条线上的其他答案,我发现 this 邮递我了解了名称空间的工作原理,以及链接的XSD文件。通过将我的新知识与那篇文章相结合,我能够构建如下内容:

require 'savon'
require 'awesome_print'
require 'byebug'
require 'pry'

endpoint = 'https://psproductdata100-stg.pcna.online'
path = 'psProductData.svc?singleWsdl'
wsdl = "#{endpoint}/#{path}"

args = {
  wsdl: wsdl,
  log: false,
  log_level: :debug,
  pretty_print_xml: true,
  element_form_default: :qualified
}

client = Savon.client(args) do
  convert_request_keys_to :lower_camelcase
  namespaces 'xmlns:shar' => 'http://www.promostandards.org/WSDL/ProductDataService/1.0.0/SharedObjects/'
end

message =  {
  'shar:wsVersion' => '1.0.0',
  'shar:id' => 'REDACTED',
  'shar:password' => 'REDACTED'

}
response = client.call(:get_product_sellable) do
  message(message)
end

ap response.body[:get_product_sellable_response][:product_sellable_array][:product_sellable][0..2]

现在在晚宴上和我聊天更有趣了。

命名空间存在类似问题 ruby savon and wsdl namespacing .我相信你也有同样的问题。

附加说明:尝试使用SOAP UI调试从WSDL生成的XML,并查看差异。还要将XML更改为从代码生成的XML,并在SOAP UI中验证XML。它将显示SOAP UI中的错误(如果有),这将使调试更快,错误更容易理解。

我认为您的问题是名称空间问题。wsVersion位于共享对象命名空间“ins0”内。它不在“tns”命名空间中。尝试更改您的请求,使其如下所示:

<env:Body>
  <tns:GetProductSellableRequest>
    <ins0:wsVersion>1.0.0</ins0:wsVersion>
  </tns:GetProductSellableRequest>
</env:Body>
