[英]Java Android: Getting Xml File from Webservice with SOAP
I have a C# Webservice and an Eclipse Android Application project. 我有一个C#Web服务和一个Eclipse Android应用程序项目。 I am trying to get a xml file from the webservice with KSOAP2 version 2.3.
我正在尝试使用KSOAP2 2.3版从Web服务获取xml文件。 The webservice works and gives me back the current xml document and it also seems like i get a connection to the webservice with the android application, but i always get an exception saying that the webservice does not recognize the value of the HTTP Header "SOAPAction".
该Web服务正常工作,并给我返回了当前的xml文档,似乎我也已使用android应用程序连接到该Web服务,但我总是收到一个异常,说该Web服务无法识别HTTP标头“ SOAPAction”的值。
Webservice: 网络服务:
namespace WebService3

[WebService(Namespace = "http://tempuri.org/")]

class DBConnect
{
private MySqlConnection connection;
private string server;
private string database;
private string uid;
private string password;
}
private void Initialize()
{
server = "localhost";
database = "eagles_db";
uid = "root";
password = "";
string connectionString;
connectionString = "SERVER=" + server + ";" + "DATABASE=" +
database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";";
connection = new MySqlConnection(connectionString);
}
public XmlDocument abmeldungen()

XmlDocument doc = new XmlDocument();

List<int> lstIDs = new List<int>();

string conStr = ConfigurationManager.ConnectionStrings["dbstring"].ConnectionString;
string befehl = "Select abmeldung.cf_created, abmeldung.datum, abmeldung.grund, web_users.name From abmeldung Inner Join web_users On abmeldung.cf_user_id = web_users.id Order By abmeldung.cf_created Desc";
MySql.Data.MySqlClient.MySqlCommand cmd = new MySqlCommand(befehl, connection);
connection.Open();
MySql.Data.MySqlClient.MySqlDataReader reader = cmd.ExecuteReader();
root = doc.CreateElement("Abmeldungen");
doc.AppendChild(root);
tempHeader = doc.CreateElement("Abmeldungen"); //doc.CreateElement(reader["reportTitle"].ToString());
root.AppendChild(tempHeader);
while (reader.Read())
{
tempInhalt = doc.CreateElement("Name");
tempHeader.AppendChild(tempInhalt).InnerText = reader["name"].ToString();
tempInhalt = doc.CreateElement("Grund");
tempHeader.AppendChild(tempInhalt).InnerText = reader["grund"].ToString();
tempInhalt = doc.CreateElement("datum");
tempHeader.AppendChild(tempInhalt).InnerText = reader["datum"].ToString();
tempInhalt = doc.CreateElement("erstellt");
tempHeader.AppendChild(tempInhalt).InnerText = reader["cf_created"].ToString();
}
reader.Close();
connection.Close();
return doc;
}
[WebMethod]
public XmlDocument abmeldung()
{
DBConnect con1 = new DBConnect();
return con1.abmeldungen();
}

I used 10.10.2.2 as localhost because on the emulated android device the normal "localhost" would be localhost of the emulated device and 10.10.2.2 is the right localhost. 我使用10.10.2.2作为本地主机,因为在模拟的android设备上,正常的“本地主机”将是模拟设备的本地主机,而10.10.2.2是正确的本地主机。
I hope my question isn't too confusing, i would appreciate it very much if anybody could help me. 我希望我的问题不要太混乱,如果有人可以帮助我,我将不胜感激。 Thank you
谢谢
public static String SOAP_ACTION = "http://10.0.2.2:28266/Service1.asmx/abmeldung";
I think your soap action should be something like, 我认为您的肥皂动作应该是这样的,
"http://tempuri.org/Service1/abmeldung"
You need to check this in your wsdl. 您需要在wsdl中进行检查。
Open your wsdl in browser using, 使用浏览器在浏览器中打开wsdl,
http://10.0.2.2:28266/Service1.asmx
Search wsdl:binding tag in wsdl. 在wsdl中搜索wsdl:binding标记。
Within binding tag search for operation ambeldung 在绑定标签中搜索操作ambeldung
You can find your SOAP Action defined as, 您可以找到定义为的SOAP操作,
<wsdl:binding name="BasicHttpBinding_Service1" type="tns:example">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="ambeldung">
<soap:operation soapAction="http://tempuri.org/examplesoapaction/example" style="document"/>
