二.WindowsAzureSQLReporting应用程序集成

DeviceinformationsettingsinSSRSareusedtopassparameterstoarenderingextension.Formoreinformationregardingdeviceinformationsettingsinreportingservices,seePassingDeviceInformationSettingstoRenderingExtensions.

ForSQLReporting,noneoftheoptionsspecifiedintheabovearticlearefeasible.Weseealotofscenarioswherewewouldwanttomodifythesesettings,andrender/exportthereportintheformatthatwearelookingfor.

ForSQLReportingreports,wecanexploretheSOAPAPIsinmodifyingthesedeviceinformationsettingsattheruntime.IfwehaveintegratedSQLReportingwithinourapplications,thisapproachisreallyeasy,byjustcreatingaseparatefunction.

Herearesomestepstoachievethis:

GeneratetheproxyclassforReportExecution2005.asmx.

Inthebrowser,gotothepathforyourendpoint.Forexample:https://<INSTANCE_NAME>.report.int.mscds.com/ReportServer/ReportExecution2005.asmx

Ifpromptedforcredentials,typeyourSQLReportingusernameandpasswordandclickSignIn.AWSDLfilewillbedisplayedinthebrowser.

OpentheVisualStudioCommandPromptandrunthewsdl.execommandtogeneratetheproxyclass.Forexample:wsdl/language:CS/n:"ReportExecution2005"https://<INSTANCE_NAME>.report.int.mscds.com/ReportServer/ReportExecution2005.asmx

Nowyouhavethefilenamed:ReportExecutionService.cs.AddthefiletoyourWindowsAzureProject.Youcanuseafunctionsimilartotheoneprovidedbelow:

publicvoidRender_Export()

ReportExecutionServicers=newReportExecutionService();

rs.Url=String.Format("https://{0}:443/ReportServer/reportExecution2005.asmx",ConfigurationManager.AppSettings["SERVER_NAME"]);

rs.CookieContainer=newCookieContainer();

rs.LogonUser(ConfigurationManager.AppSettings["USERNAME"],ConfigurationManager.AppSettings["PASSWORD"],ConfigurationManager.AppSettings["SERVER_NAME"]);

byte[]result=null;

stringreportPath="/SSRSReport/Report5";

stringformat="CSV";

stringhistoryID=null;

//Settingthedeviceinfoparameters

stringdevInfo=@"<DeviceInfo><FieldDelimiter>;</FieldDelimiter></DeviceInfo>";

stringencoding;

stringmimeType;

stringextension;

Warning[]warnings=null;

string[]streamIDs=null;

ExecutionInfoexecInfo=newExecutionInfo();

ExecutionHeaderexecHeader=newExecutionHeader();

rs.ExecutionHeaderValue=execHeader;

execInfo=rs.LoadReport(reportPath,historyID);

StringSessionId=rs.ExecutionHeaderValue.ExecutionID;

//codesnippettosettheDataSourcecredentials.

if(execInfo.CredentialsRequired)

List<DataSourceCredentials>credentials=newList<DataSourceCredentials>();

foreach(DataSourcePromptdspinexecInfo.DataSourcePrompts)

DataSourceCredentialscred=newDataSourceCredentials();

cred.DataSourceName=dsp.Name;

cred.UserName=ConfigurationManager.AppSettings["USERNAME"];

cred.Password=ConfigurationManager.AppSettings["PASSWORD"];

credentials.Add(cred);

Console.WriteLine("Settingdatasourcecredentials...");

execInfo=rs.SetExecutionCredentials(credentials.ToArray());

//Codesnippettorenderthefiletoaspecifiedformat.

try

result=rs.Render(format,devInfo,outextension,outencoding,outmimeType,outwarnings,outstreamIDs);

execInfo=rs.GetExecutionInfo();

catch(Exceptionex)

throwex;

//CodesnippettowritethefiletoaspecificlocationusingFileStreamobject

try

FileStreamstream=File.Create(@"D:\report.csv",result.Length);

Console.WriteLine("Filecreated.");

stream.Write(result,0,result.Length);

Console.WriteLine("Resultwrittentothefile.");

stream.Close();

catch(Exceptionex)

Console.WriteLine(ex.Message);

YoucanuseaconfigfiletostoretheUsername,PasswordandSQLReportingservername.Theconfigfilewillhaveinformationasspecifiedbelow:

<appSettings>

<addkey="SERVER_NAME"value="SQLReportingServer.reporting.windows.net"/>

<addkey="USERNAME"value="UserName"/>

<addkey="PASSWORD"value="Password"/>

</appSettings>

ModifythevaluesasperyourSQLReportingserverdetails.

YoumightneedtoextendthedefaultReportingServicesproxyclasstoenablecookiemanagement,becauseSQLReportingusesformsauthentication.
