python用suds 调用webservice方法的时候报错。

Posted 2023-05-16

from suds.client import Client
from suds.transport.https import HttpAuthenticated

def main():
url = '此处省略/ConfWebServiceInterface.wsdl'
client = Client(url,faults=False)
#print client
result = client.service.DelBlackList(1117,1133)
print result

if __name__=="__main__":
main()

client获取没有问题。一般这种错误是什么错误，我用这个调过公共webservice没有问题，我想是不是这个webservice有什么不一样有什么或者是区分什么东西，求懂的大神！

报错：

参考技术A 其实用Python进行webservice通信进行数据交换，就是拼接字符串，没必要用第三方的库。

Python调用webservice接口

python调用webservice接口，这里我们使用suds包

如果没有直接cmd命令安装subs包 

pip suds install 

安装成功会有提示成功字样。

 

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－

首先导入包

先查看一下webservice提供哪些类型及方法，之后我们才知道怎么调用，传哪些参数。

from suds.client import Client
from suds.transport.https import HttpAuthenticated #webservice需要安全难证

t = HttpAuthenticated(username=‘RFCATUSER‘,password=‘q123456‘) #安全验证所需用户，密码
url = "http://hqxt1.sinopec.com:50000/dir/wsdl?p=sa/65bd52bd76de381daf15736a37d13ab1"
test = Client(url,transport=t)
print test

下面开始调用传参：

#coding=utf-8

#导入包
from suds.client import Client
from suds.transport.https import HttpAuthenticated #webservice需要安全难证

 

#安全验证，获取service服务

t = HttpAuthenticated(username=‘RFCATUSER‘,password=‘q123456‘) #安全验证所需用户，密码

url = "http://hqxt1.sinopec.com:50000/dir/wsdl?p=sa/65bd52bd76de381daf15736a37d13ab1"
test = Client(url,transport=t)
print test

 

#用test.factory.create创建实例

request=test.factory.create(‘DT_IPM_SEND_PSBUDGET_REQ‘)

IPM_MSG_HEAD = test.factory.create(‘MSG_HEAD‘)

request.IS_MSG_HEAD = IPM_MSG_HEAD

IPM_MSG_HEAD.SENDTIME = ‘20170421102908‘
IPM_MSG_HEAD.RECIVER = ‘ECC‘
IPM_MSG_HEAD.SENDER = ‘IPM‘
IPM_MSG_HEAD.INTERFACE_ID = ‘PROJECT_CREATE‘
IPM_MSG_HEAD.SPRAS = None
IPM_MSG_HEAD.OPERATOR = None
IPM_MSG_HEAD.SYSTEM_ID = None
IPM_MSG_HEAD.PROXY_ID = None
IPM_MSG_HEAD.GUID = None
IPM_MSG_HEAD.MANDT = None
request.IV_BUKRS = "X060"
request.IV_TESTRUN = "X"

request.IT_PSBUDGET=[]

#用test.service.XXXXX去调用方法
m=test.service.SI_IPM_SEND_PSBUDGET_REQ_A_OUT(request)
print IPM_MSG_HEAD
print request
