python用httplib直接实现soap协议

1.先拿一段php的soap代码来看：

<?php 
$client = new SoapClient("http://ws.sb.com/messageservice.asmx?wsdl",Array('trace'=>True)); 
// 参数转为数组形式传递 
$aryPara = array('sender' => 'dantezhu', 
    'receiver' => 'dantezhu', 
    'title' => 'OZ评论消息提醒', 
    'msgInfo' => 'sss', 
    'messageType'=>0); 
// 调用远程函数 
$ret = $client->SendRTX($aryPara); 
var_dump($ret); 
echo $client->__getLastRequest(); 
?>

这段代码是能够正确的发送请求的，通过__getLastRequest打出发送包，如下：

<?xml version="1.0" encoding="UTF-8"?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://ws.sb.com/common/message"> 
    <SOAP-ENV:Body> 
        <ns1:SendRTX> 
            <ns1:sender>dantezhu</ns1:sender> 
            <ns1:receiver>dantezhu</ns1:receiver> 
            <ns1:title>OZ评论消息提醒</ns1:title> 
            <ns1:msgInfo>sss</ns1:msgInfo> 
            <ns1:messageType>0</ns1:messageType> 
        </ns1:SendRTX> 
    </SOAP-ENV:Body> 
</SOAP-ENV:Envelope>

2.再来看一下用suds的代码：

from suds.client import Client 
def SendRtx(target,title,content): 
    url = "http://ws.sb.com/messageservice.asmx?wsdl" 
    client = Client(url) 
    client.service.SendRTX( 
            sender = 'dantezhu', 
            receiver = target, 
            title = title, 
            msgInfo = content, 
            messageType = 0  
            )    
    senddata = client.last_sent() 
    recvdata = client.last_received() 
    f = file('ss.txt','wb') 
    f.write(str(senddata)) 
    f.close() 
    print senddata 
    print '--------------------------------' 
    print recvdata 
SendRtx('dantezhu',u'OZ我的天','ss')

发送包XML如下：

   <SOAP-ENV:Header/> 
   <ns1:Body> 
      <ns0:SendRTX> 
         <ns0:sender>dantezhu</ns0:sender> 
         <ns0:receiver>dantezhu</ns0:receiver> 
         <ns0:title>OZ我的天</ns0:title> 
         <ns0:msgInfo>ss</ns0:msgInfo> 
         <ns0:messageType>0</ns0:messageType> 
      </ns0:SendRTX> 
   </ns1:Body> 
</SOAP-ENV:Envelope>

3.仔细对比，发现确实发送的XML是不一样的，但是看了半天也没有发现suds的client有能够手工修改的地方。于是最终决定用urllib或者httplib直接实现。
比较幸运的是找到了这个链接，里面针对不同的webservice提供了不同的方法：

我们只要模拟一下php的发送的XML，用python来发送就可以啦~
而我们使用的webservice是.net2.0,所以代码如下：

        </SOAP-ENV:Body> 
    </SOAP-ENV:Envelope>''' 
    SoapMessage = SENDTPL % (target,title,content) 
    webservice = httplib.HTTP("ws.sb.com") 
    webservice.putrequest("POST", "/messageservice.asmx") 
    webservice.putheader("Host", "ws.sb.com") 
    webservice.putheader("User-Agent", "Python Post") 
    webservice.putheader("Content-type", "text/xml; charset=\"UTF-8\"")

    webservice.putheader("SOAPAction", "\"http://ws.sb.com/common/message/SendRTX\"") 
    webservice.endheaders() 
    webservice.send(SoapMessage) 
    # get the response 
    statuscode, statusmessage, header = webservice.getreply() 
    print "Response: ", statuscode, statusmessage 
    print "headers: ", header 
    print webservice.getfile().read() 
SendRtx('dantezhu',"素材管理系统","您的单")

OK，问题解决~果然底层是最靠谱的呀~
