ASP 调用Web Service 异常

ASP 调用Web Service 错误

VB code

Dim url,host,method,xmlns,soapAction,soapRequest,xmlDocument 
 host = "www.caohejing.web" 
 url = "http://www.caohejing.web/webservice/news/Default.asmx" 
 method = "POST" 
 xmlns = "http://www.caohejing.com/NewsService/" 
     soapAction = "http://www.caohejing.com/NewsService/NewsAction" 
  
 'xmlDocument = CreateXmlDocument() 
     xmlDocument="new" 
  
 '拼接请求字符串 
 soapRequest = "<?xml version='1.0' encoding='utf-8'?>" 
 soapRequest = soapRequest & " <soap12:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap12='http://www.w3.org/2003/05/soap-envelope'> " 
 soapRequest = soapRequest & " <soap12:Body>" 
 soapRequest = soapRequest & " <NewsAction xmlns='"& xmlns &"'>" 
 soapRequest = soapRequest & " <newsXML>"& xmlDocument &"</newsXML>" 
     'soapRequest = soapRequest & " <newsXML>test msg</newsXML>" 
 soapRequest = soapRequest & " </NewsAction> " 
 soapRequest = soapRequest & " </soap12:Body>" 
 soapRequest = soapRequest & " </soap12:Envelope>" 
     response.Write(soapRequest) 
  
 '创建XMLHttp连接,并传输数据 
 Set xmlhttp = server.CreateObject("Msxml2.XMLHTTP") 
 xmlhttp.Open "POST",url,false 
 xmlhttp.setRequestHeader "Content-Type", "text/xml;charset=utf-8" 
 xmlhttp.setRequestHeader "HOST", host 
 xmlhttp.setRequestHeader "Content-Length",LEN(soapRequest) 
 xmlhttp.setRequestHeader "SOAPAction", soapAction 'WEBSERVICE的命名空间+ "/" + 调用的方法名称 
 xmlhttp.Send(SoapRequest)

Web Service 调用的例子

VB code

POST /webservice/news/Default.asmx HTTP/1.1Host: www.caohejing.webContent-Type: text/xml; charset=utf-8Content-Length: lengthSOAPAction: "http://www.caohejing.com/NewsService/NewsAction"<?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>    <NewsAction xmlns="http://www.caohejing.com/NewsService/">      <newsXML>string</newsXML>    </NewsAction>  </soap:Body></soap:Envelope>

执行结果:400 Bad Request


[解决办法]

400?

就是不存在这个东西。。。

应该首先去确定一下是不是路径有问题。。
[解决办法]
完全按照下面的 拼凑字符串，然后用xmlhttp发送能行吗？

看你2段代码 ，前面的是soap12:Envelope
[解决办法]
客气了
首先 你asp代码中
url = "http://www.caohejing.web/webservice/news/Default.asmx"
这个地址从我这是打不开的
如果是有其他测试地址，先把这里改过来 ws完整的测试地址 

你下面ws的post调用例子里 写的是相对地址POST /webservice/news/Default.asmx HTTP/1.1


[解决办法]
哦 
但是你asp代码里的调用地址写的是带域名的
第三行
url = "http://www.caohejing.web/webservice/news/Default.asmx"
倒数第六行

xmlhttp.Open "POST",url,false

你把这个url改成 本地的测试地址应该就行了
[解决办法]
CreateXmlDocument() 这个函数拼凑的xml应该需要编码才能加入 原始soap字串中

具体怎么做你可以 使用c#写个客户端调用你的ws 然后用fiddler等监听下请求

我这截获的http post调用的原始请求是：
