.net webservice 概览 阅读asp.net的QuickStart
1、定义WebService
2、WS-I Basic Profile 1.1 支持
3、禁用压缩
4、使用Session
5、Schema 验证
6、service的异步调用
7、客户端调用时动态配置WebService的url
8、在Service中抛出SOAP的异常
9、使用SOAP Headers 添加附加信息(如:身份信息)
10、使用默认的网络身份验证
1、定义WebService
页面上
使用WebService命令指定页面的类型为WebService和实现Service的类
<%@ WebService Language="C#" CodeBehind="~/App_Code/BaseOne.cs" Class="BaseOne" %>
类定义
使用WebService属性表示定义的Service Class
[WebService(Namespace = "http://test.com/webservice")]
使用WebMethod属性定义Service 方法
[WebMethod(Description="test description!",MessageName="HelloWorld2")]
2、WS-I Basic Profile 1.1 支持
asp.net 2.0 实现了对 WS-I Basic Profile 1.1 Conformance 的支持,只需要在service class上使用WebServiceBinding 属性标示一下就可以了,虽然看了一会那个BP1.1也没看到什么所以然
[WebServiceBinding(ConformsTo=WsiProfiles.BasicProfile1_1, EmitConformanceClaims=true)]
3、禁用压缩
在客户端使用代理时设置
EnableDecompressionService service = new EnableDecompressionService();
service.EnableDecompression = true;
4、使用Session
//On the client you must add the following code (for session state only):
serviceName.CookieContainer = new System.Net.CookieContainer();
//Setting EnableSession to true allows state to be persisted per Session
[WebMethod(EnableSession=true)]
public String UpdateSessionHitCounter() {
//update the session "HitCounter" here
return Session["HitCounter"].ToString();
}
5、Schema 验证
//create the validating reader
XmlTextReader tr = new XmlTextReader(input, XmlNodeType.Document, null);
XmlValidatingReader vr = new XmlValidatingReader(tr);
//add the schema and set the validation type to schema
XmlSchemaCollection schemas = new XmlSchemaCollection();
schemas.Add("Microsoft.Samples.Web.Services", "insert location here...");
vr.Schemas.Add(schemas);
vr.ValidationType = ValidationType.Schema;
//add our event callback function to the event handler in case there is a validation error
vr.ValidationEventHandler += new ValidationEventHandler (ValidationHandler);
try
{
//if there is an error we will fall out of this while loop and our callback function will be called
while (vr.Read())
{
//do nothing
}
}
catch (Exception exception)
{
//an exception will be thrown if there are non-validation errors, e.g. in the case of malformed XML
}
6、service的异步调用
//First implement the HelloWorldCompleted method using the following signature:
//public void HelloWorldCompleted(object sender, HelloWorldCompletedEventArgs args)
//Create the Web service
HelloWorldWaitService service = new HelloWorldWaitService();
//Add our callback function to the event handler
service.HelloWorldCompleted += this.HelloWorldCompleted;
//Call the Web service asynchronously
service.HelloWorldAsync("first call");
//when the Web service call returns the HelloWorldCompleted method will be called
7、客户端调用时动态配置WebService的url
<configuration>
<appSettings>
<add key="WSUrl" value="insert location here..." />
</appSettings>
</configuration>
HelloWorldService service = new HelloWorldService();
//Change the location of the Web service in machine.config if desired
service.Url = System.Configuration.ConfigurationSettings.AppSettings["WSUrl"];
output.Text = service.HelloWorld();
8、在Service中抛出SOAP的异常
//assume that there was an error validating the SOAP Message
if(true)
{
XmlDocument doc = new XmlDocument();
//insert your own XML into the XmlDocument,
//this will go into the Detail element of the SOAP fault
string errorMsg = "An error was received...";
//the SOAP fault will contain a human-readable error message,
//the fault code, the SOAP actor, and the detail element
SoapException exc = new SoapException(errorMsg, SoapException.ClientFaultCode, "", detail);
throw exc;
}
9、使用SOAP Headers 添加附加信息(如:身份信息)
客户端调用
// On the server, create the AuthHeader class which extends from SoapHeader
public class AuthHeader : SoapHeader {
public string Username;
public string Password;
}
// On the client, create a new instance of the AuthHeader class
AuthHeader myHeader = new AuthHeader();
//WARNING: This sample is for demonstration purposes only. Username/password information is sent in plain text,
//which should never be done in a real application. It is not secure without modification.
myHeader.Username = "JaneDoe";
myHeader.Password = "password";
// Set the AuthHeader public member of the Web service instance to myHeader
service.AuthHeaderValue = myHeader;
// Call the Web service, which automatically sends the header with the request
string answer = service.HelloWorld();
服务器端接收
// AuthHeader class extends from SoapHeader
public class AuthHeader : SoapHeader {
public string Username;
public string Password;
}
[WebService(Description="Simple sample to demonstrate use of SOAP Headers", Namespace="Microsoft.Samples.XmlMessaging.WebServices")]
public class HeaderService {
public AuthHeader sHeader;
[WebMethod(Description="This method requires a custom soap header set by the caller")]
[SoapHeader("sHeader")]
public string SecureMethod() {
if (sHeader == null)
return "ERROR: Please supply credentials";
string usr = sHeader.Username;
string pwd = sHeader.Password;
if (AuthenticateUser(usr, pwd)) {
return "SUCCESS: " + usr;
}
else {
return "ERROR: Could not authenticate";
}
}
private bool AuthenticateUser(string usr, string pwd) {
if ((usr != null)&&(pwd != null)) {
// could query a database here for credentials...
return true;
}
return false;
}
}
10、使用默认的网络身份验证
UseDefaultCredentialsService service = new UseDefaultCredentialsService();
service.UseDefaultCredentials = true;
使用XmlSchema验证xml的正确性
XmlValidatingReader
XmlSchemaCollection
ValidationType = ValidationType.Schema;
vr.ValidationEventHandler += new ValidationEventHandler (ValidationHandler);
code in quickstart from asp.net
<%@ Webservice Language="C#" Class="MessageValidationService" %>
using System;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Xml;
using System.Xml.Serialization;
using System.Xml.Schema;
using System.IO;
[WebService(Namespace="Microsoft.Samples.XmlMessaging.WebServices")]
public class MessageValidationService {
private string returnMessage = "Success! Validation was successful.";
[WebMethod]
public string SendToValidator(string input)
{
XmlTextReader tr = new XmlTextReader(input, XmlNodeType.Document, null);
XmlValidatingReader vr = new XmlValidatingReader(tr);
XmlSchemaCollection schemas = new XmlSchemaCollection();
schemas.Add("Microsoft.Samples.Web.Services", "http://66.129.71.130/quickstartv20/ webservices/samples/ MessageValidation/Book.xsd");
vr.Schemas.Add(schemas);
vr.ValidationType = ValidationType.Schema;
vr.ValidationEventHandler += new ValidationEventHandler (ValidationHandler);
try
{
while (vr.Read())
{
//do nothing
}
}
catch (Exception exception)
{
returnMessage = "Failure. An Exception was received, most likely indicating malformed XML. Message: " + exception.Message;
}
return returnMessage;
}
public void ValidationHandler(object sender, ValidationEventArgs args)
{
returnMessage = "Failure. Validation was not successful. Message: " + args.Message;
}
}

sql中使用指定字符分离长字符串,并以table形式输出
以前记得有这么一个方法,但是找不到了 所以只好自己写一个了
sql中使用指定字符分离长字符串,并以table形式输出
例子
select * from SplitString('abc,aadd,asdf,,asdf,,asdf',',')
结果
substr
------------------------------------------------------------------------------------------------------------------------abc
aadd
asdf
asdf
asdf
(5 row(s) affected)
--------------------------------------
方法代码
-----------------
Create FUNCTION SplitString
(
@string as nvarchar(2048),
@split as nvarchar(50)
)
RETURNS @reports TABLE(substr nvarchar(2048))
AS
begin
declare @start_location as int
declare @begin as int
declare @end as int
declare @substr as nvarchar(255)
set @start_location=0
while(len(@string)>0)
begin
select @begin=Charindex(@split,@string,@start_location)
select @end=Len(@split)
if(@begin>0)
begin
select @substr = Substring(@string,0,Charindex(@split,@string,@start_location))
select @string = Substring(@string,@begin+@end,len(@string))
end
else
begin
select @substr=@string
select @string='';
