Web service with soapheader added to the flex call

1. Write a web service that requires soapheader authentication in. net

Code 1: WebService. CS

Using system. Web. Services;
Using system. Web. Services. Protocols;

[WebService (namespace = "http://www.microsoft.com/")] // namespace, pay attention to the flex call to manually fill in
[Webservicebinding (conformsto = wsiprofiles. basicprofile1_1)]
Public class WebService: system. Web. Services. WebService {

Public WebService (){}

Public authenticationinfo;

[Webmethod]
[Soapheader ("authenticationinfo")] // Add soapheader to the service
Public String helloworld (){
If (authenticationinfo = NULL ){
Return "the verification information cannot be blank ."
}
Else {
If (authentication. Check (authenticationinfo. username, authenticationinfo. Password )){
Return "Hello world! "
}
Else {
Return "failed to verify the user name and password. You have no right to access this service. "
}
}
}
}

// User password verification class
Public class authentication {
Public static bool check (string username, string password ){
Return (username = "user") & (Password = "password "));
}
}

Code 2: authenticationinfo. CS

Using system;
Using system. Data;
Using system. configuration;
Using system. Web;
Using system. Web. Security;
Using system. Web. UI;
Using system. Web. UI. webcontrols;
Using system. Web. UI. webcontrols. webparts;
Using system. Web. UI. htmlcontrols;

/// <Summary>
/// Abstract description of authenticationinfo
/// </Summary>
Public class authenticationinfo: system. Web. Services. Protocols. soapheader {
Public authenticationinfo (){}
Public authenticationinfo (string username, string password ){
This. Username = username;
This. Password = password;
}
Public String username;
Public String password;
}

2. Net calls the Web service using the soapheader

Code 3: form1.cs

Using system;
Using system. Collections. Generic;
Using system. componentmodel;
Using system. Data;
Using system. drawing;
Using system. text;
Using system. Windows. forms;

Namespace windowsapplication1 {
Public partial class form1: FORM {
Public form1 (){
Initializecomponent ();
}
Private void button#click (Object sender, eventargs e ){
Localhost. WebService Service = new windowsapplication1.localhost. WebService ();
Localhost. authenticationinfo Au = new windowsapplication1.localhost. authenticationinfo ();
Au. Username = textbox1.text;
Au. Password = textbox2.text;
Service. authenticationinfovalue = AU;
Label3.text = service. helloworld ();
}
}
}

3. Call this web service in flex

Code 4: soapheadertest. mxml

<? XML version = "1.0" encoding = "UTF-8"?>
<Mx: Application xmlns: MX = "http://www.adobe.com/2006/mxml" layout = "absolute" fontfamily = "simsun" fontsize = "12">
<Mx: SCRIPT>
<! [CDATA [
Import MX. rpc. Events. faultevent;
Import MX. rpc. Events. resultevent;

Private function invoke (): void {
WS. clearheaders (); // clear it first
VaR auinfo: authentication = new authentication (txtuser. Text, txtpassword. Text );//
WS. addheader (auinfo); // Add
WS. helloworld (); // call the service
}
Private function wsresult (Event: resultevent): void {
Lblinformation. Text = event. Result. tostring ();
}
Private function wsfault (Event: faultevent): void {
Lblinformation. Text = event. Message. tostring ();
}
]>
</MX: SCRIPT>
<Mx: WebService id = "ws" WSDL = "http: // localhost: 4443/websites/WebService. asmx? WSDL"
Result = "wsresult (event)" fault = "wsfault (event)"/>
<Mx: textinput id = "txtuser" x = "98" Y = "94"/>
<Mx: textinput id = "txtpassword" x = "98" Y = "124"/>
<Mx: Label x = "29" Y = "98" text = "User:"/>
<Mx: Label x = "29" Y = "128" text = "Password:"/>
<Mx: button x = "193" Y = "166" label = "INVOKE" Click = "INVOKE ()"/>
<Mx: Label x = "29" Y = "213" text = "label" id = "lblinformation"/>
</MX: Application>

Code 5: authenticationinfo.

Package {
Public class authenticationinfo {// The field name must be consistent with that of. net.
Public var Username: string;
Public var password: string;
}
}

Code 6: authentication.

Package {
Import MX. rpc. Soap. soapheader;

Public class authentication extends soapheader {
Public var Username: string;
Public var password: string;
Public Function authentication (User: String, password: string ){
VaR content: authenticationinfo = new authenticationinfo ();
Content. Username = user;
Content. Password = password;
VaR QNAME: QNAME = new QNAME ("http://www.microsoft.com/", "authenticationinfo ");
Super (QNAME, content );
}
}
}
