[英]Extract SOAP body from a SOAP message
我想從SOAP消息中提取SOAP主體,我在SOAP主體中有一些數據,我必須在日期庫中解析,所以這是代碼:
public string Load_XML(string SoapMessage)
{
//check soap message
if (SoapMessage == null || SoapMessage.Length <= 0)
throw new Exception("Soap message not valid");
//declare some local variable
int iSoapBodyStartIndex = 0;
int iSoapBodyEndIndex = 0;
//load the Soap Message
//Učitaj string XML-a i pretvori ga u XML
XmlDocument doc = new XmlDocument();
try
{
doc.Load(SoapMessage);
}
catch (XmlException ex)
{
WriteErrors.WriteToLogFile("WS.LOAD_DOK_LoadXML", ex.ToString());
throw ex;
}
//search for the "http://schemas.xmlsoap.org/soap/envelope/" URI prefix
string prefix = string.Empty;
for (int i = 0; i < doc.ChildNodes.Count; i++)
{
System.Xml.XmlNode soapNode = doc.ChildNodes[i];
prefix = soapNode.GetPrefixOfNamespace("http://schemas.xmlsoap.org /soap/envelope/");
if (prefix != null && prefix.Length > 0)
break;
}
//prefix not founded.
if (prefix == null || prefix.Length <= 0)
throw new Exception("Can't found the soap envelope prefix");
//find soap body start index
int iSoapBodyElementStartFrom = SoapMessage.IndexOf("<" + prefix + ":Body");
int iSoapBodyElementStartEnd = SoapMessage.IndexOf(">", iSoapBodyElementStartFrom); -> HERE I HAVE AN ERROR!!!!
iSoapBodyStartIndex = iSoapBodyElementStartEnd + 1;
//find soap body end index
iSoapBodyEndIndex = SoapMessage.IndexOf("</" + prefix + ":Body>") - 1;
//get soap body (xml data)
return SoapMessage.Substring(iSoapBodyStartIndex, iSoapBodyEndIndex - iSoapBodyStartIndex + 1);
}
我在這里收到錯誤:
int iSoapBodyElementStartEnd = SoapMessage.IndexOf(">", iSoapBodyElementStartFrom);
錯誤:
指數超出范圍。 必須是非負數且小於集合的大小。
如果有人知道如何解決這個問題?
對於這樣的請求:
String request = @"<?xml version=""1.0"" encoding=""UTF-8""?>
<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance""
xmlns:soapenc=""http://schemas.xmlsoap.org/soap/encoding/""
xmlns:xsd=""http://www.w3.org/2001/XMLSchema""
xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
<soap:Body>
<ResponseData xmlns=""urn:Custom"">some data</ResponseData>
</soap:Body>
</soap:Envelope>";
以下代碼完成了解包數據並獲取<ReponseData>
xml內容的工作:
XDocument xDoc = XDocument.Load(new StringReader(request));
var unwrappedResponse = xDoc.Descendants((XNamespace)"http://schemas.xmlsoap.org/soap/envelope/" + "Body")
.First()
.FirstNode
Linq2Xml更易於使用。
string xml = @"<?xml version=""1.0"" encoding=""UTF-8"" ?>
<soap:envelope xmlns:xsd=""w3.org/2001/XMLSchema"" xmlns:xsi=""w3.org/2001/XMLSchema-instance"" xmlns:soap=""schemas.xmlsoap.org/soap/envelope/"">;
<soap:body>
<order> <id>1234</id> </order>
</soap:body>
</soap:envelope>";
XDocument xDoc = XDocument.Load(new StringReader(xml));
var id = xDoc.Descendants("id").First().Value;
- 編輯 -
循環body
元素:
XDocument xDoc = XDocument.Load(new StringReader(xml));
XNamespace soap = XNamespace.Get("schemas.xmlsoap.org/soap/envelope/");
var items = xDoc.Descendants(soap+"body").Elements();
foreach (var item in items)
{
Console.WriteLine(item.Name.LocalName);
}
您可以使用GetElementsByTagName
來提取soap請求的正文。
private static T DeserializeInnerSoapObject<T>(string soapResponse)
{
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml(soapResponse);
var soapBody = xmlDocument.GetElementsByTagName("soap:Body")[0];
string innerObject = soapBody.InnerXml;
XmlSerializer deserializer = new XmlSerializer(typeof(T));
using (StringReader reader = new StringReader(innerObject))
{
return (T)deserializer.Deserialize(reader);
}
}
簡單的解決方案,如果身體有多個孩子,你只需要刪除信封:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(placeYourXmlHere);
if (xmlDoc.DocumentElement.Name == "soapenv_Envelope")
{
string tempXmlString = xmlDoc.DocumentElement.InnerXml;
xmlDoc.LoadXml(tempXmlString);
}
如果要刪除Envelope和body,其中body僅包含一個子節點:
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(placeYourXmlHere);
while (xmlDoc.DocumentElement.Name == "soapenv_Envelope" || xmlDoc.DocumentElement.Name == "soapenv_Body")
{
string tempXmlString = xmlDoc.DocumentElement.InnerXml;
xmlDoc.LoadXml(tempXmlString);
}
現在xml被縮減為Body的內容
