Question

我正在设置一个使用API的程序，最近我刚刚设法使该程序将请求发送到服务器并成功接收到响应，但是我无法使用该响应，可能我知道它是如何工作的？

我试图直接从python文件中从响应中检索值，并将它们放在两个不同位置的两个独立文件中，但是这两种方法都失败了。

import requests
import xml.etree.ElementTree as ET

    def sendRequest():
        request =""" 

        <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://website">
         <soapenv:Header/>
         <soapenv:Body>
              <eter:test1>
                <!--Optional:-->
                <eter:_user>luac</eter:_user>
                <!--Optional:-->
                <eter:_pwd>124</eter:_pwd>
              </object>
         </soapenv:Body>
        </soapenv:Envelope>"""
    #encoded_request = request.encode('utf-8')
        headers = {"Host": "172.54.21.14",
               "Content-Type": "text/xml",
               "Content-Length": "length"}

        response = requests.post(url="http:/website\?",
                             headers = headers,
                             data = request)
        print (response.text)
        print (response.status_code)
        with open("testSave.xml", "w") as f:
            f.write(response.text)

    def getValue():
        tree = ET.parse('testSave.xml')
        root = tree.getroot()
        print (root.tag)
        print (root.attrib)
        for mdv in root:
            print (mdv)

    sendRequest()
    getValue()

期望put能够显示变量及其值。

实际输出是tree = ET.parse('testSave.xml')处的nameError

这是我尝试使用的响应xml

    <?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><GetAvailableMetadeviceListResponse xmlns="http://www.etere.eu/EtereWSApi"><GetAvailableMetadeviceListResult><?xml version="1.0" encoding="utf-8"?>

<WSApiResponse>

<Function Name="MD_GetAvailableMetadeviceList">

<mdv id_metadevice="3" description="LOWRES"/><mdv id_metadevice="16" description="ETX-G"/><mdv id_metadevice="18" description="subs"/><mdv id_metadevice="23" description="ARCHIVE"/><mdv id_metadevice="32" description="System Storage"/>

</Function>

</WSApiResponse>

</GetAvailableMetadeviceListResult></GetAvailableMetadeviceListResponse></soap:Body></soap:Envelope>

Answer 1

这里

import xml.etree.ElementTree as ET

xml = ''' <?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><GetAvailableMetadeviceListResponse xmlns="http://www.etere.eu/EtereWSApi"><GetAvailableMetadeviceListResult>

<WSApiResponse>

<Function Name="MD_GetAvailableMetadeviceList">

    <mdv id_metadevice="3" description="LOWRES"/>
    <mdv id_metadevice="16" description="ETX-G"/>
    <mdv id_metadevice="18" description="subs"/>
    <mdv id_metadevice="23" description="ARCHIVE"/>
    <mdv id_metadevice="32" description="System Storage"/>

</Function>

</WSApiResponse>

</GetAvailableMetadeviceListResult></GetAvailableMetadeviceListResponse></soap:Body></soap:Envelope>


'''
#
# Assuming all we care about is under <Function>
#
start_idx = xml.index('<Function')
end_idx = xml.index('</Function>')
xml = xml[start_idx:end_idx + 11]
root = ET.fromstring(xml)
mdv_list = root.findall('.//mdv')
for mdv in mdv_list:
    print('{} --> {}'.format(mdv.attrib.get('id_metadevice'),mdv.attrib.get('description')))

输出

3 --> LOWRES
16 --> ETX-G
18 --> subs
23 --> ARCHIVE
32 --> System Storage

Answer 2

with open("testSave.txt", "r+") as f:
    f.write(response.text)

with open("testSave.txt", "r+") as f:
    content= f.read()
    f.seek(0)
    f.truncate()
    f.write(content.replace('&lt;','<'))

with open("testSave.txt", "r+") as f:
    content= f.read()
    f.seek(0)
    f.truncate()
    f.write(content.replace('&gt;','>'))


with open('testSave.txt', 'r') as f2:
    data= f2.read()
    print(data)
    start_idx = data.index('<Function')
    end_idx = data.index('</Function>')
    data = data[start_idx:end_idx + 11]
    root = ET.fromstring(data)
    mdv_list = root.findall('.//mdv')
    for mdv in mdv_list:
        print('{} --> {}'.format(mdv.attrib.get('id_metadevice'),mdv.attrib.get('description')))

我找到了解决方案，这使我可以编写响应，更改所有的“＆lt;”和'＆gt;'到“ <”和“>”，然后使用@balderman提供的代码，提取所需的数据！谢谢！
