SharePoint WebService Application

SharePoint Comes With WebService, which is generally accessed across servers, because different websites on the same server can access data simply by raising the permission code.

Take reading a list across servers as an example, add "http: // <server-URL>/_ vti_bin/lists to the project. asmx and http: // <server-URL>/_ vti_bin/sitedata. asmx reference.

The two references are named listservice and sitedataservice respectively.

// Access the list library. an XML file is returned through the caml query. The dataset type is assigned directly without parsing.

Public static dataset getitems ()

{
Listservice. Lists listsws = new listservice. Lists ();
// Listsws. Credentials = system. net. credentialcache. defaultcredentials; // This sentence can be replaced by the next sentence in the compiling environment, but the next sentence must be used for cross-server applications.
Listsws. Credentials = new networkcredential (username, password, domain name );
Xmldocument Doc = new system. xml. xmldocument ();
Doc. loadxml ("<document> <query> <where> caml </where> </query> <viewfields/> <queryoptions/> </document> ");
Xmlnode listquery = Doc. selectsinglenode ("// query ");
Xmlnode listviewfields = Doc. selectsinglenode ("// viewfields ");
Xmlnode listqueryoptions = Doc. selectsinglenode ("// queryoptions ");

Guid G = getwebid ();

Xmlnode items = listsws. getlistitems ("listname", String. Empty, listquery, listviewfields, String. Empty, listqueryoptions, G. tostring ());

Nametable Nt = new system. xml. nametable ();
Xmlnamespacemanager nsmgr = new xmlnamespacemanager (NT );
Nsmgr. addnamespace ("W", "http://schemas.microsoft.com/office/word/2003/2/wordml ");
Xmlnode y = items. selectsinglenode ("*", nsmgr );
Dataset DS = new dataset ();
If (y! = NULL)
{
Xmlreader = new xmltextreader (Y. innerxml, xmlnodetype. element, null );
DS. readxml (xmlreader );
}
Return Ds;
}

Private Static guid getwebid ()
{
Sitedataservice. sitedata sitedataws = new sinopecsitedata. sitedata ();
Sitedataws. Credentials = new networkcredential (username, password, domain name );
Sitedataservice. _ swebmetadata webmetadata;
Sitedataservice. _ swebwithtime [] arrwebwithtime;
Sitedataservice. _ slistwithtime [] arrlistwithtime;
Sitedataservice. _ sfpurl [] arrurls;
String roles; string [] roleusers; string [] rolegroups;
Uint I = sitedataws. getweb (Out webmetadata, out arrwebwithtime, out arrlistwithtime, out arrurls, out roles, out roleusers, out rolegroups );
Guid G = new GUID (webmetadata. webid );
Return g;

}

Pay special attention to the following two points for the above Code:

1. Authentication. For web references, you can directly modify the address in webconfig. You can modify the authentication login information in the corresponding code. We recommend that you obtain the information in the configuration file for unified maintenance.

2. Parse XML.
