通过HTTP调用Soap Web服务，提供异常“Connection close” [英] Calling Soap web service over HTTP giving exception "Connection close"

问题描述

我通过HTTP调用Web服务，但无法连接。例外是连接关闭。想知道为什么它被关闭虽然相同的SOAP消息在SOAP UI中工作。我可以在从SOAP UI复制时使用URN操作。请说明有什么问题。



我的C＃代码如下。

I am calling Web service over HTTP but it is failing to connect. Exception is connection close. Wondering why it is closed though same SOAP message works in SOAP UI. Can I give Action with URN as I copyed from SOAP UI. Please suggest what is wrong.

My C# code is as follows.

using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;

推荐答案

订单是正确的。我的python代码连接但又在C＃中怎么做。看看它是否有助于你修复。



进口suds

来自suds.client import客户

来自suds.wsse import *

def main（）：



url ='https://webservices.cp.com/webservices/ cphargepoint / services / 4.1'

wsdl ='https://webservices.cp.com/api.wsdl'

#API用户和密码

api_user ='yrewte44'

api_pass ='eg430'



＃创建客户端并在soap标头中添加安全令牌

client =客户端（url = wsdl，location = url）

security =安全（）

token = UsernameToken（api_user，api_pass）

security.tokens.append（令牌）

client.set_options（wsse =安全）

试试：

＃un-comment下面的print语句查看所有已发布的

＃CP服务SOAP方法的列表。

＃print client



＃getPublicStations（）服务方法接受一种'stationSearchRequest'

searchQuery = client.factory.create（'stationSearchRequest'）

#add properties / filter options

searchQuery.Proximity = 10

searchQuery.proximityUnit ='M'

#create goeData，提供起点坐标

geoData = client.factory.create（'geoData'）

geoData.Lat = 37.425758

geoData.Long = -122.097807

searchQuery .Geo = geoData



＃这里是对服务的实际调用

response = client.service.getPublicStations（searchQuery）

＃对数据做任何事情

＃打印回复

除了suds.WebFault详细信息：

打印细节


if __name __ ==__ main__：

main（）

Order is correct. I python code to connect but again how to do in C#. See if it can help in fixing for you.

import suds
from suds.client import Client
from suds.wsse import *
def main():

url = 'https://webservices.cp.com/webservices/cphargepoint/services/4.1'
wsdl = 'https://webservices.cp.com/api.wsdl'
# API user and password
api_user = 'yrewte44'
api_pass = 'eg430'

# create client and add security tokens in the soap header
client = Client(url=wsdl, location=url)
security = Security()
token = UsernameToken(api_user, api_pass)
security.tokens.append(token)
client.set_options(wsse=security)
try:
# un-comment the print statement below to see the list of all published
# CP service SOAP methods.
# print client

# getPublicStations() service method accepts a type of 'stationSearchRequest'
searchQuery = client.factory.create('stationSearchRequest')
# add properties/filter options
searchQuery.Proximity = 10
searchQuery.proximityUnit = 'M'
# create goeData, provide starting point co-ordinates
geoData = client.factory.create('geoData')
geoData.Lat = 37.425758
geoData.Long = -122.097807
searchQuery.Geo = geoData

# here is the actual call to the service
response = client.service.getPublicStations(searchQuery)
# do whatever with the data
# print response
except suds.WebFault as detail:
print detail

if __name__=="__main__":
main()
