Use Delphi to develop Web Service database programs-general Linux technology-Linux programming and kernel information. The following is a detailed description. Step 1: Write server applications
First, select "File | New | Other…" in Delphi IDE ...", Then select the Soap Server Application icon on the WebServices page.
Then, in the New Soap Server Application dialog box, select Web App Debugger executable.
After you click OK, Delphi will automatically generate a WebModule, which contains three WebServices controls.
Then select the Soap Server Data Module icon on the WebServices page. After OK, the Soap Data Module Wizard dialog box is displayed in Delphi.
In Class Name, enter the Class Name: D6DBDataModule1. After you click OK, Delphi will automatically generate a SOAP data module. In this module, add the TdataBase, Tquery, and TdataSetProvider controls.
The properties of each control are basically the same as those of previous Delphi Database applications. TdataSetProvider is a DataAccess control that supports remote calls.
Compile and execute the application to register it. Complete the application design on the server.
Step 2: Compile the client application
Add a new application project, and add the TDBNavigator and TDBGrid controls in the Form.
Add a data module, and add the TSaopConnection, TclientDataSet, and TdataSource controls.
The TSaopConnection control uses the SOAP protocol to connect to the remote server.
Http: // WebServer address/WebService Application name/soap/SoapServerDataModule name
Set the properties of the TclientDataSet control, set the RemoteServer property to the name of the TsaopConnection control, and click ProviderName.
Next, add the following code to the unit where the form is located:
