启动Zeep客户端时收到无效的XML内容

Question

当我像这样初始化一个Zeep客户端时

url = 'http://www.filmratings.com/Filmratings_CARA/WebCaraSearch/Service.asmx?wsdl'
client = Client(wsdl = url)

我收到了这个错误信息

XMLSyntaxError: Invalid XML content received (Opening and ending tag mismatch: p line 122 and ul, line 124, column 20)

我尝试了这里提到的解决方案，但都没有成功。我感觉我可能需要通过某个参数来改变XML解析器的工作方式，但由于我对这个库还不太熟悉，所以不太确定。

Answer 1

概述

#1 检查 WSDL

打开浏览器，访问这个网址

https://www.filmratings.com/Filmratings_CARA/WebCaraSearch/Service.asmx?wsdl

应该会显示 XML 内容

#2 获取函数列表

SoapUI 开源工具

把 WSDL 的网址粘贴到这里，然后点击 OK

你可以看到函数列表

#3 测试函数

点击其中一个函数

然后点击 Request1

在 <cara:search> 中输入 Superman

在 <cara:year> 中输入 1978

然后点击 ▶

接着在下一个面板中点击 XML 标签 这就是函数调用的结果

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body>
      <GetExportWithTitleYearResponse xmlns="http://cara.org/">
         <GetExportWithTitleYearResult><![CDATA[<?xml version="1.0" encoding="utf-8"?><SearchResults><title><name><![CDATA[Superman]]]]>><![CDATA[</name><year><![CDATA[1978]]]]>><![CDATA[</year><url><![CDATA[http://www.imdb.com/find?q=Superman]]]]>><![CDATA[</url><rating><![CDATA[PG]]]]>><![CDATA[</rating><ratingReason><![CDATA[]]]]>><![CDATA[</ratingReason><distributor><![CDATA[Warner Bros. Inc.]]]]>><![CDATA[</distributor></title></SearchResults>]]></GetExportWithTitleYearResult>
      </GetExportWithTitleYearResponse>
   </soap:Body>
</soap:Envelope>

#4 测试 zeep

用 zeep 进行相同的函数 保存为 test-function.py 文件名

from zeep import Client

# URL of the SOAP service
url = 'https://www.filmratings.com/Filmratings_CARA/WebCaraSearch/Service.asmx?wsdl'

client = Client(url)

# Call the GetExportWithTitleYear method
response = client.service.GetExportWithTitleYear(search='Superman', year='1978')

print(response) # Print the XML data

在运行之前，你需要先安装依赖。

pip install zeep

运行它

python test-function.py

结果

<?xml version="1.0" encoding="utf-8"?><SearchResults><title><name><![CDATA[Superman]]></name><year><![CDATA[1978]]></year><url><![CDATA[http://www.imdb.com/find?q=Superman]]></url><rating><![CDATA[PG]]></rating><ratingReason><![CDATA[]]></ratingReason><distributor><![CDATA[Warner Bros. Inc.]]></distributor></title></SearchResults>

#5 数据转换

将打印 XML，并提取关键值对为 JSON 格式的数据。

from zeep import Client
import xml.dom.minidom
import xml.etree.ElementTree as ET
import json

# URL of the SOAP service
url = 'https://www.filmratings.com/Filmratings_CARA/WebCaraSearch/Service.asmx?wsdl'

client = Client(url)

# Call the GetExportWithTitleYear method
response = client.service.GetExportWithTitleYear(search='Superman', year='1978')

dom = xml.dom.minidom.parseString(response) # Parse the XML string

pretty_xml = dom.toprettyxml()

print(pretty_xml) # Print the XML data

root = ET.fromstring(response)

data = {}

# Loop through child elements of the root element
for child in root:
    for item in child:
        tag = item.tag
        text = item.text.strip() if item.text else ""
        data[tag] = text

json_data = json.dumps(data, indent=4)

print(json_data) # Print the JSON data

结果

<?xml version="1.0" ?>
<SearchResults>
        <title>
                <name><![CDATA[Superman]]></name>
                <year><![CDATA[1978]]></year>
                <url><![CDATA[http://www.imdb.com/find?q=Superman]]></url>
                <rating><![CDATA[PG]]></rating>
                <ratingReason/>
                <distributor><![CDATA[Warner Bros. Inc.]]></distributor>
        </title>
</SearchResults>
