下面就是调用webservice时,网络上大家发送的数据包了
client请求数据:
post /webhelloz5/service1.asmx http/1.1
host: localhost
content-type: text/xml
content-length: length
soapaction: "http://tempuri.org/helloworld"
<?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>
<helloworld xmlns="http://tempuri.org/">
<narg>int</narg>
<strarg>string</strarg>
</helloworld>
</soap:body>
</soap:envelope>
server回应数据:
http/1.1 200 ok
content-type: text/xml; charset=utf-8
content-length: length
<?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>
<helloworldresponse xmlns="http://tempuri.org/">
<helloworldresult>string</helloworldresult>
</helloworldresponse>
</soap:body>
</soap:envelope>
vc7下的自动生成的代理类,如下所示:
template <typename tclient>
inline hresult cservice1t<tclient>::helloworld(
int narg,
bstr strarg,
bstr* helloworldresult
)
{
hresult __atlsoap_hr = initializesoap(null);
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_initialize_error);
return __atlsoap_hr;
}
cleanupclient();
ccomptr<istream> __atlsoap_spreadstream;
__cservice1_helloworld_struct __params;
memset(&__params, 0x00, sizeof(__params));
__params.narg = narg;
__params.strarg = strarg;
__atlsoap_hr = setclientstruct(&__params, 0);
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_outofmemory);
goto __skip_cleanup;
}
__atlsoap_hr = generateresponse(getwritestream());
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_generate_error);
goto __skip_cleanup;
}
__atlsoap_hr = sendrequest(_t("soapaction: \"http://tempuri.org/helloworld\"\r\n"));
if (failed(__atlsoap_hr))
{
goto __skip_cleanup;
}
__atlsoap_hr = getreadstream(&__atlsoap_spreadstream);
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_read_error);
goto __skip_cleanup;
}
// cleanup any in/out-params and out-headers from previous calls
cleanup();
__atlsoap_hr = beginparse(__atlsoap_spreadstream);
if (failed(__atlsoap_hr))
{
setclienterror(soapclient_parse_error);
goto __cleanup;
}
*helloworldresult = __params.helloworldresult;
goto __skip_cleanup;
__cleanup:
cleanup();
__skip_cleanup:
resetclientstate(true);
memset(&__params, 0x00, sizeof(__params));
return __atlsoap_hr;
}
流程为:
1 初始化参数列表( setclientstruct(&__params, 0);)
|
v
2.生成发送数据请求(generateresponse(getwritestream());sendrequest(_t("soapaction: \"http://tempuri.org/helloworld\"\r\n"));)
|
v
3.接收和解析回应数据(beginparse(__atlsoap_spreadstream);)
|
v
4.清理工作
python代码:

return ret
def hello_world(self,argl):

header[soapaction]=\"%s/%s\"%(self.xmlns,func)
conn=httplib.httpconnection(addr[1])
print self.gen_request(func,self.xmlns,argd)
conn.request(post,/webhelloz5/service1.asmx,self.gen_request(func,self.xmlns,argd),header)
resp=conn.getresponse()
dataxml=resp.read()
def start_element(name, attrs):
pass
def end_element(name):
if name==helloworldresult:
self.ret=self.data
#elif name==ourputarg:
# argl[0]=self.temp
def char_data(data):
self.data=data
pxml=xml.parsers.expat.parsercreate()
pxml.startelementhandler = start_element
pxml.endelementhandler = end_element
pxml.characterdatahandler = char_data
pxml.parse(dataxml, 1)
except:
return none
return self.ret
def test():
a=zfive5web("http://127.0.0.1/webhelloz5/service1.asmx","http://tempuri.org")
l=[1,121]
ret=a.hello_world([1,121])
if __name__ == __main__:
assert test()
流程与上差不多如果实现分析.asmx?wdsl文件就完全可以vs中的添加web引用的功能，这里
剩下的主要是特殊符号的处理和类型转化工作。
