Erstellen eines Webdienstes mit FastReport.Service.dll
We have an easy way to implement a web service using the library FastReport.Service.dll (WCF Service Library), which is supplied with FastReport .Net.
Our example is based on creating a simple web application with a web service functions, but you can modify your existing project based on .NET Framework 4.0 or newer.
Run Visual Studio and create a new ASP.NET Web Application project under .NET Framework 4.0.
Add references on libraries FastReport.dll, FastReport.Bars.dll, FastReport.Service.dll
Create a new text file with name ReportService.svc in site root.
Add next lines in file:
<%@ ServiceHost Service="FastReport.Service.ReportService" %> <%@ Assembly Name="FastReport.Service" %>
Open web.config and add next sections in <configuration>:
<appSettings> <!-- path to folder with reports --> <add key="FastReport.ReportsPath" value="C:\Program files\FastReports\FastReport.Net\Demos\WCF" /> <!-- name of connection string for reports --> <add key="FastReport.ConnectionStringName" value="FastReportDemo" /> <!-- Comma-separated list of available formats PDF,DOCX,XLSX,PPTX,RTF,ODS,ODT,MHT,CSV,DBF,XML,TXT,FPX. You can delete any or change order in this list. --> <add key="FastReport.Gear" value="PDF,DOCX,XLSX,PPTX,RTF,ODS,ODT,MHT,CSV,DBF,XML,TXT,FPX" /> </appSettings> <connectionStrings> <add name="FastReportDemo" connectionString="XsdFile=;XmlFile=C:\Program Files\FastReports\FastReport.Net\Demos\Reports\nwind.xml"/> </connectionStrings> <system.serviceModel> <services> <service behaviorConfiguration="FastReportServiceBehavior" name="FastReport.Service.ReportService"> <endpoint address="" binding="wsHttpBinding" contract="FastReport.Service.IFastReportService"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="FastReportServiceBehavior"> <serviceMetadata httpGetEnabled="True" /> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <basicHttpBinding> <binding messageEncoding="Mtom" closeTimeout="00:02:00" openTimeout="00:02:00" receiveTimeout="00:10:00" sendTimeout="00:02:00" maxReceivedMessageSize="67108864" maxBufferSize="65536" transferMode="Streamed"> <security mode="None"> <transport clientCredentialType="None" /> </security> </binding> </basicHttpBinding> </bindings> </system.serviceModel>
The key "FastReport.ReportsPath" should contain a path to folder with reports. You can set demo folder «\FastReport.Net\Demos\WCF» for example.
The key "FastReport.ConnectionStringName" should contain connection string name. This line should be registered in section <connectionStrings>.
Let's run our site and check the availability of a Web service by access to a file ReportService.svc.
When you deploy the project on the server, be sure to check for files FastReport.dll, FastReport.Bars.dll, FastReport.Service.dll in the folder /bin.
Examples of client programs can be found in the folder \FastReport.Net\Demos\C#\WCFClient and \FastReport.Net\Demos\C#\WCFWebClient. Open each project in Visual Studio and right click on ReportService and select Configure Service Reference.
Specify the address of an existing web service in configuration window.
To be continued.
