How to customize WebService in Moss

All WebServices provided in Moss are placed in virtual directory _ vti_bin, and the corresponding physical directory isC: \ Program Files \ common files \ microsoft shared \ Web Server Extensions \ 12 \ ISAPI. You may think the directory _ vti_bin name is a bit strange. The name is from Vermeer technologies inconfigurated of the company. The company's only product is FrontPage, which was acquired by Microsoft in 1996.

The following steps are required to implement a WebService:

1. Create a WebService Project

1. Use vs2005 to create a webserivce project to implement our WebService. Then I add a class library to implement the logic of WebService. The project structure is as follows:

Sign the mosslibrary2 class library. The project "right-click --- properties --- signature --- isProgramSet signature ", no password is used. Service. CS is the logic of the actual WebService,CodeAs follows:

 Using System; Using System. Web; Using System. Web. Services; Using System. Web. Services. Protocols; Using Microsoft. SharePoint; Using Microsoft. Sharepoint. Utilities; [WebService (namespace =" Http://tempuri.org/ ")] [Webservicebinding (conformsto = wsiprofiles. basicprofile1_1)] Public   Class Service: system. Web. Services. WebService { Public Service ()
{} [Webmethod] Public   String Helloworld ()
{ Return "Hello World ";} [Webmethod] Public   String Getsitelistcount () {spweb myweb = spcontext. Current. Web; splistcollection lists = myweb. lists; Return (Myweb. Title +" Contains "+ Lists. Count. tostring () +" Web sites. ");}}

2. Add the mosslibrary2 class library to GAC.

There are two methods:

1.Drag mosslibrary2.dll in the bin directory% WINDOWS % \ assemblyFolder.
2. Open the command line tool vs2005and use the gacui.exe tool. The command is as follows:
Gacutil.exe-if "<full file system path to DLL>".

III:Modify the service. asmx File

 
<% @WebService Language="C #"Class="Myserviceclass,Myserviceassembly,Version=1.0.0.0,
Culture=Neutral,Publickeytoken=8f2dca3c0f2d0131"%>
 

You can find mosslibrary2.dll in the % WINDOWS % \ Assembly folder and right-click it to view its properties.The logic file of the specified service. asmx uses the code in service. Cs in the mosslibrary2 project.

4. Generate the service. disco and WebService description files service. WSDL.

1. Copy Service. asmxC: \ Program Files \ common files \ microsoft shared \ Web Server Extensions \ 12 \ template \ layouts directory, open the command line tool of vs2005, and use the following command:

Disco http: // carysun/_ layouts/service. asmx

The service. disco and service. WSDL files are generated.

 
2. Set <? XML version ="1.0"Encoding ="UTF-8"?>Replace the statement with the following statement:
 

<% @ Page Language ="C #"Inherits ="System. Web. UI. Page"%>
<% @ Assembly name ="Microsoft. Sharepoint, version = 12.0.0.0, culture = neutral,
Publickeytoken = 71e9bce111e9429c"%>
<% @ Import namespace ="Microsoft. Sharepoint. Utilities"%>
<% @ Import namespace ="Microsoft. SharePoint"%>
<% Response. contenttype ="Text/XML"; %>
 

In fact, the original pure XML is transformed into a page for parsing. In addition, the parsing of this page is processed by moss.

3. Set

 <  Contractref   Ref =Http: // carysun/_ layouts/service. asmx? WSDL  
 Docref = "Http: // carysun/_ layouts/service. asmx"   Xmlns = Http://schemas.xmlsoap.org/disco/scl"   />  <  Soap   Address = "Http: // carysun/_ layouts/service. asmx"   Xmlns : Q1 = Http://tempuri.org/  
Binding = "Q1: servicesoap"   Xmlns = Http://schemas.xmlsoap.org/disco/soap"   />  <  Soap   Address = "Http: // carysun/_ layouts/service. asmx"   Xmlns : Q2 = Http://tempuri.org/  
 Binding ="Q2: servicesoap12"   Xmlns = Http://schemas.xmlsoap.org/disco/soap"   /> 

Replace:

 <  Contractref   Ref = <%   Sphttputility . Addquote ( Sphttputility . Htmlencode ( Spweb . Originalbaseurl
 ( Request ) + "? WSDL "), Response . Output ); % >  
Docref = < % Sphttputility. addquote (sphttputility. htmlencode (spweb. originalbaseurl (request )),
Response. Output); % > Xmlns = "http://schemas.xmlsoap.org/disco/scl/"/>
 <  Soap   Address = <%   Sphttputility . Addquote ( Sphttputility . Htmlencode ( Spweb . Originalbaseurl ( Request )),
 Response . Output ); % > Xmlns: Q1 = "http://tempuri.org/" binding = "Q1: helloworld"
Xmlns = "http://schemas.xmlsoap.org/disco/soap/"/>
<  Soap   Address = <%   Sphttputility . Addquote ( Sphttputility . Htmlencode ( Spweb . Originalbaseurl ( Request )),
 Response . Output ); % > Xmlns: q2 = "http://tempuri.org/" binding = "Q2: servicesoap12"
Xmlns = "http://schemas.xmlsoap.org/disco/soap/"/>












4. Set



 















<  Soap : Address   Location = "Http: // carysun/_ layouts/service. asmx"   /> And<  Soap12 : Address   Location = "Http: // carysun/_ layouts/service. asmx"   /> 

Replace:
< Soap : Address Location = <% Sphttputility . Addquote ( Sphttputility .Htmlencode ( Spweb . Originalbaseurl
( Request )), Response . Output ); % > />
And < Soap12 : Address Location = <% Sphttputility . Addquote ( Sphttputility . Htmlencode ( Spweb . Originalbaseurl
( Request )), Response . Output ); % > />

 
The changes to contractref and soap address are actually re-encoded with the soap query URL on the page.
Moss-hosted web services can be correctly located based on dynamic requests during runtime.
 

5. Rename service. disco and service. WSDL to servicedisco. aspx and servicewsdl. aspx.

5. Deploy WebService

Copy servicedisco. aspx, servicewsdl. aspx, and service. asmxC: \ Program Files \ common files \ microsoft shared \ Web Server Extensions \ 12 \ ISAPI directory. Then we can check whether the deployment is successful through the following address.Http: // carysun/_ vti_bin/service. asmx.

For example:

Vi. Client call

Create a window application, add the WebService application, and add the following code when you click an event in the button:

 
Carysun. Service Se =NewWindowsapplication1.carysun. Service ();
Se. usedefacrecredentials =True;
MessageBox. Show (SE. getsitelistcount ());
 

Se. usedefacrecredentials = true; this code sets trust. Otherwise, an error indicating no permission is reported.

The final effect is:
