我正在尝试使用 wsdl 文件向网络服务器发送同步肥皂消息。我根据 IronPython 中的说明为 wsdl 文件创建了一个 cs 文件和 dll 以在 IronPython 中加载。我已经创建了我的肥皂消息（网络服务需要），但我认为我没有正确构建我的 webRequest。

这是我的代码：

    import clr
clr.AddReference("System")
clr.AddReferenceToFileAndPath("C:\\Temp\MeetingSpaceService.dll")
clr.AddReference("System.Xml")
clr.AddReference("System.Web.Services")

from MeetingSpaceService import MeetingSpaceService
service = MeetingSpaceService()
from System.Net import WebClient
from System.IO import StreamWriter
from System.IO import StreamReader
from  System.IO import StringWriter

from System import Uri
from System.Xml import XmlTextWriter
from System.Xml import Formatting
from System.Web.Services import *
from System.Net import HttpWebRequest
import System.Object

import System.Byte
from System.Xml import XmlDocument
from System.IO import File
from System.Object import ToString
#from System.ServiceModel.Description import WsdlImporter as wsdl 
from System.Web.Services.Description import (ServiceDescription,     ServiceDescriptionImporter)
from System.Web.Services.Protocols import SoapHttpClientProtocol
from System.IO import MemoryStream
from System.Net import WebClient

readerboard = ''' <?xml version="1.0" encoding="utf-8"?>

"'''

uriString = "https://ice-services.starwoodhotels.com/readerboard‏"
uri = Uri(uriString)

try: 
webRequest = HttpWebRequest.Create(uri)
webRequest.ContentType = "text/xml;charset=\"utf-8\""
webRequest.Accept = "text/xml"
webRequest.ContentLength = readerboard.Length
webRequest.Timeout = 1000000000
webRequest.Method = "POST"
webRequest.GetRequestStream()
webRequest.Write(readerboard)
webRequest.GetResponse()
except Exception, e:
    print (9)

我在这里进行了更改，现在这就是我得到的。Web 服务是同步的，所以我相信正在发生的是，当您发送请求时，响应会自动返回。在点

rqt = webRequest.GetRequestStream() 在读取下一行之前大约有 1.5 到 2.5 秒的延迟。这模仿了 SOAPUi 中的行为，其中在发送消息后通常会有一秒左右的延迟，然后返回的 XML 数据显示在响应框中。我在想，在 rqt= webRequest 之后，我需要以某种方式读取流而不要求响应。我可以将我创建的用于导入 WSDL 的 cs 文件和 dll 发送给您，看看您的想法。那时您应该能够访问服务器并在 IDE 中看到我在说什么。我感谢您的帮助。太感谢了。

以下是上述操作之后发生的情况：

>>> rqt = webRequest.GetRequestStream()
>>> rqt.Write(byte1,0,byte1.Length)
>>>
>>>     #get the response here
>>> rsp = webRequest.GetResponse()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
SystemError: The remote server returned an error: (500) Internal Server Error.
>>>     #create a stream reader to convert the raw response into UTF8 for text
>>> readStream = StreamReader(rsp.GetResponseStream(), System.Text.Encoding.UTF8
)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'rsp' is not defined
>>>     #read the data from the stream into a string
>>> data = readStream.ReadToEnd()

当您发出请求以表示 SOAPAction 时，您需要添加一个标头。

所以像：

webRequest.Headers.Add('SOAPAction', '"http://myservice.com/1/poll"')

调用 Web 服务的完整代码如下。在这种情况下http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL

import clr

from System.Net import WebClient
from System.IO import StreamReader
import System.Text
from System import Uri
from System.Net import HttpWebRequest

#This is the SOAP Payload 
#Just build it with basic concats
readerboard = """<?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>
    <GetCityWeatherByZIP xmlns="http://ws.cdyne.com/WeatherWS/">
      <ZIP>10011</ZIP>
    </GetCityWeatherByZIP>
  </soap:Body>
</soap:Envelope>"""


uriString = "http://wsf.cdyne.com/WeatherWS/Weather.asmx"
uri = Uri(uriString)

try: 
    webRequest = HttpWebRequest.Create(uri)
    webRequest.ContentType = "text/xml;charset=\"utf-8\""
    webRequest.Accept = "text/xml"
    webRequest.Timeout = 1000000000
    webRequest.Method = "POST"
    #We set the SOAPAction Header - this tells the end point what service to run
    webRequest.Headers.Add('SOAPAction', '"http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP"') 

    #we turn the payload into a byte array to allow us to write it to the request stream
    encoding = System.Text.UTF8Encoding();
    byte1 = encoding.GetBytes(readerboard);
    #write the bytes above to the request
    rqt = webRequest.GetRequestStream()
    rqt.Write(byte1,0,byte1.Length)
    #get the response here
    rsp = webRequest.GetResponse()
    #create a stream reader to convert the raw response into UTF8 for text
    readStream = StreamReader(rsp.GetResponseStream(), System.Text.Encoding.UTF8)
    #read the data from the stream into a string
    data = readStream.ReadToEnd()
    readStream.Close()
    rsp.Close()
    #Do stuff with the data here
    print data
except System.Net.WebException, we:
    print "Web Exception:", we.Message
    if we.Status == System.Net.WebExceptionStatus.ProtocolError: 
        print int(we.Response.StatusCode), we.Response.StatusDescription
        print (StreamReader(we.Response.GetResponseStream(), System.Text.Encoding.UTF8)).ReadToEnd()
except Exception, e:
    print e
