让我先说我对 SOAP 以及事情应该如何工作仍然很陌生。我正在使用垂直响应 API。

我在获取 suds 以正确构造请求的 xml 时遇到问题。这是一些代码：

from suds.client import Client

url = 'https://api.verticalresponse.com/wsdl/1.0/VRAPI.wsdl'
client = Client(url)
vr = client.service
...
test_list = (
    (
        {
            'name' : 'email_address',
            'value' : login['username'],
        },
        {
            'name' : 'First_Name',
            'value' : 'VR_User',
        }
    ),
    (
        {
            'name' : 'email_address',
            'value' : 'api-support@verticalresponse.com',
        },
        {
            'name' : 'First_Name',
            'value' : login['username'],
        },
    ),
)

# sid and cid are correctly retrieved prior to this point
print "Sending test message..."
vr.sendEmailCampaignTest({
    'session_id' : sid,
    'campaign_id' : cid,
    'recipients' : test_list,
})

在这种情况下 login['username'] 只是一个电子邮件地址。

该代码引发此错误：

suds.WebFault: Server raised fault: 'Application failed during request deserialization: Too many elements in array. 4 instead of claimed 2 (2)

这里是 sendEmailCampaignTest 的定义：http: //developers.verticalresponse.com/api/soap/methods/campaigns/sendemailcampaigntest/

这是记录输出的 xml。 此 XML 不正确且不起作用（我删除了 session_id 和 list_id 以便在此处显示）：

我正在基于以下 ruby​​ 脚本（由 Vertical Response 提供）移植我的脚本：

test_list = [
           [{
              'name' => 'email_address',
              'value' => $username
            },
            {
              'name' => 'First_Name',
              'value' => 'VR_User'
            }
           ],
           [{
              'name' => 'email_address',
              'value' => 'api-support@verticalresponse.com'
            },
            {
              'name' => 'First_Name',
              'value' => $username
            }
           ]
          ]
print "Sending test message...\n"
temp0 = vr.sendEmailCampaignTest({
                                 'session_id' => sid,
                                 'campaign_id' => cid,
                                 'recipients' => test_list,
                               })

它输出以下 xml。 这个 XML 是正确的并且可以工作（我删除了 session_id 和 list_id）：

我了解错误在于收件人的构造。它应该包含两个项目，每个项目包含两个项目，但我使用 suds 的 python 脚本将其设置为包含四个未嵌套的项目。所以我的问题是我怎样才能得到正确构造 xml 的泡沫？

编辑：我尝试过的：

>>> url = 'https://api.verticalresponse.com/wsdl/1.0/VRAPI.wsdl'
>>> client = Client(url)
>>> args = client.factory.create('ns0:sendEmailCampaignTestArgs')  
>>> args
(sendEmailCampaignTestArgs){
   session_id = None
   campaign_id = None
   recipients = 
      (ArrayOfNVDictionary){
         _arrayType = ""
         _offset = ""
         _id = ""
         _href = ""
         _arrayType = ""
      }
 }

在我看来，suds 没有正确构造 ArrayOfNVDictionary（它没有可以保存 NVDictionary 的实际数组元素），任何有助于确定你会很棒。

SOAP 的全部意义在于远程方法调用和参数应该看起来像您选择的语言的本机方法和对象。

为了避免错误，请始终使用特定的 SOAP 类型，如此（未经测试）代码段中所示：

>>> recipient_list = [ 
...     ('root@eruditorum.org', 'Enoch'), 
...     ('billg@microsoft.com', 'Bill'), 
... ]
>>> client = suds.client.Client('https://api.verticalresponse.com/wsdl/1.0/VRAPI.wsdl')
>>> args = client.factory.create('ns0:sendEmailCampaignTestArgs')
>>> for email, first_name in recipient_list:
...     recipient = client.factory.create('ns0:NVDictionary')
...     recipient['email_address'] = email
...     recipient['First_Name'] = first_name
...     args.recipients.append(nvdict)
>>> args.session_id = sid
>>> args.campaign_id = cid
>>> client.service.sendEmailCampaignTest(args)

恕我直言，像上面这样的显式代码更干净，更易于维护。

当然你可以忽略我的建议，在这种情况下我猜test_list应该是这样的：

test_list = [ 
    { 
        'email_address': 'josh@cartme.com', 
        'First_Name': 'Josh' },
    },
    { 
        'email_address': 'josh.cartme@gmail.com', 
        'First_Name': 'Josh' },
    },
]
