suds英文什么意思,suds是什么的缩写

1. 查看服务接口

import sudsclient=suds.client.Client('xxxx_webservice_url') def get_all_methods(client): return [method for method in client.wsdl.services[0].ports[0].methods]

 

2. 查看某个具体接口的传输参数及类型

def get_method_args(client, method_name): method = client.wsdl.services[0].ports[0].methods[method_name] input_params = method.binding.input return input_params.param_defs(method)

 

3. 调用接口服务

client.service.xxx_function(....)

 

4. 关于调试

输出之前调用服务接口时发送了什么soap报文，以及收到什么样的soap报文

print 'last sent:n', client.last_sent()print 'last recv:n', client.last_received()

 当服务器返回报文格式不规范时(非wsdl中定义的），client.last_received()为None。这个时候显然对联调极为不利。

 那就利用suds自身的日志记录看看咯。设定如下：

import sys
import logginglogger = logging.getLogger('suds') logger.setLevel(logging.DEBUG) logger.addHandler(logging.StreamHandler(sys.stdout))

如果只关心传输了什么，则可以限定logger为“suds.transport.http“

import syslogger = logging.getLogger('suds.transport.http') logger.setLevel(logging.DEBUG) logger.addHandler(logging.StreamHandler(sys.stdout))

 5. 异常的捕捉和输出

try: client.service.xxx_func(*args, **kwargs)except suds.WebFault,ex: print ex.fault print ex.document

 

 

 

后记：对于第三方库莫名其妙的问题，果断及时拿源码过来剖析（至少debug）

 

DEMO

 来个demo说明如何运用，如下：

>>> import suds>>> url='http://www.gpsso.com/webservice/kuaidi/kuaidi.asmx?wsdl'>>> client = suds.client.Client(url) >>> print get_all_methods(client) [KuaidiQuery] >>> print get_method_args(client, 'KuaidiQuery') [(Compay, <Element:0x7f6c55bc43d0 name="Compay" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />), (OrderNo, <Element:0x7f6c55bc4450 name="OrderNo" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />)] >>> print client.service.KuaidiQuery(Company='EMS', OrderNo='1111') (KuaidiQueryResult){ API = (API){ RESULTS = "0" MESSAGE = "接口查询成功" } } >>> print client.last_sent() <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:ns0="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://gpsso.com/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header/> <ns0:Body> <ns1:KuaidiQuery> <ns1:OrderNo>1111</ns1:OrderNo> </ns1:KuaidiQuery> </ns0:Body> </SOAP-ENV:Envelope> >>> print client.last_received() <?xml version="1.0" encoding="UTF-8"?> <soap:Envelope> <soap:Body> <KuaidiQueryResponse xmlns="http://gpsso.com/"> <KuaidiQueryResult> <API> <RESULTS>0</RESULTS> <MESSAGE>接口查询成功</MESSAGE> </API> </KuaidiQueryResult> </KuaidiQueryResponse> </soap:Body> </soap:Envelope>
