使用Suds的Soap客户端

Question

Python中的SOAP调用

你好，上面是我之前关于SOAP的问题。在那里，我传递了一个一维数组。现在我的问题是，我需要将一个二维数组传递给以下SOAP结构。

请求结构

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <CalculateWeb2DObjectArray xmlns="http://tempuri.org/">
      <HCID>string</HCID>
      <jaggedobjDataMICRO>
        <ArrayOfAnyType>
          <anyType />
          <anyType />
        </ArrayOfAnyType>
        <ArrayOfAnyType>
          <anyType />
          <anyType />
        </ArrayOfAnyType>
      </jaggedobjDataMICRO>
      <numeratorID>int</numeratorID>
    </CalculateWeb2DObjectArray>
  </soap:Body>
</soap:Envelope>

响应结构

 <?xml version="1.0" encoding="utf-8"?>
    <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <soap:Body>
        <CalculateWeb2DObjectArrayResponse xmlns="http://tempuri.org/">
          <CalculateWeb2DObjectArrayResult>
            <ArrayOfAnyType>
              <anyType />
              <anyType />
            </ArrayOfAnyType>
            <ArrayOfAnyType>
              <anyType />
              <anyType />
            </ArrayOfAnyType>
          </CalculateWeb2DObjectArrayResult>
        </CalculateWeb2DObjectArrayResponse>
      </soap:Body>
    </soap:Envelope>

我的代码

from suds.xsd.doctor import Import, ImportDoctor
from suds.client import Client

# enable logging to see transmitted XML
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)

# fix broken wsdl
# add <s:import namespace="http://www.w3.org/2001/XMLSchema"/> to the wsdl
imp = Import('http://www.w3.org/2001/XMLSchema',
             location='http://www.w3.org/2001/XMLSchema.xsd')
imp.filter.add('http://tempuri.org/')
wsdl_url = 'http://204.9.76.243/nuCast.DataFeedService/Service1.asmx?WSDL'
client = Client(wsdl_url, doctor=ImportDoctor(imp))

# make request
arrayofstring1 = client.factory.create('ArrayOfString')
arrayofstring1.string = [1,2]
arrayofstring2 = client.factory.create('ArrayOfString')
arrayofstring2.string = [5,6]
arrayofstring = client.factory.create('ArrayOfString')
arrayofstring.string = [arrayofstring1,arrayofstring2]


print client.service.CalculateWeb2DObjectArray(1073757, arrayofstring, 99)

但是我在输出中得到了空值。请帮我解决这个问题。

谢谢

Answer 1

你传给 CalculateWeb2DObjectArray() 函数的参数不对。

要了解 CalculateWeb2DObjectArray() 函数接受什么类型的参数，你可以在你的脚本中添加：

print client

输出结果会包含：

CalculateWeb2DObjectArray(xs:string HCID,
                          ArrayOfArrayOfAnyType jaggedobjDataMICRO,
                          xs:int numeratorID, )

所以第二个参数应该是 ArrayOfArrayOfAnyType，你可以用 client.factory 来创建它：

aoaoat = client.factory.create('ArrayOfArrayOfAnyType')

要了解如何填充 aoaoat，你只需打印它：

print aoaoat

输出结果：

(ArrayOfArrayOfAnyType){
  ArrayOfAnyType[] = <empty>
}

对 ArrayOfAnyType 重复同样的步骤，你会得到：

(ArrayOfAnyType){
  anyType[] = <empty>
}

把这些信息整合在一起：

aoaoat = client.factory.create('ArrayOfArrayOfAnyType')
lst = aoaoat.ArrayOfAnyType = []
for L in [[1,2], [5,6]]:
    aoat = client.factory.create('ArrayOfAnyType')
    aoat.anyType = L
    lst.append(aoat)
response = client.service.CalculateWeb2DObjectArray(1073757, aoaoat, 99)
print response
