WebService access encryption and webservice Encryption

WebService access encryption and webservice Encryption
WebService encryption allows you to set the access username and password for WebService, enhancing the security of WebService so that WebService can only be used by authorized users.

Specific steps:

1. Define a soapheader derived class to verify WebService Access Permissions

1. <Span style = "font-size: 10px;"> using System;
2. Using System. Data;
3. Using System. Configuration;
4. Using System. Web;
5. Using System. Web. Security;
6. Using System. Web. UI;
7. Using System. Web. UI. HtmlControls;
8. Using System. Web. UI. WebControls;
9. Using System. Web. UI. WebControls. WebParts;
11. /// <Summary>
12. /// Summary of MySoapHeader
13. /// </Summary>
14. Public class MySoapHeader: System. Web. Services. Protocols. SoapHeader
15. {
16. Private string _ uname = string. Empty; // webservice access Username
18. Public string Uname
19. {
20. Get {return _ uname ;}
21. Set {_ uname = value ;}
22. }
23. Private string _ password = string. Empty; // webservice Access password
25. Public string Password
26. {
27. Get {return _ password ;}
28. Set {_ password = value ;}
29. }
32. Public MySoapHeader ()
33. {
34. //
35. // TODO: add the constructor logic here
36. //
37. }
38. Public MySoapHeader (string uname, string upass)
39. {
40. Init (uname, upass );
41. }
42. Private void init (string uname, string upass)
43. {
44. This. _ password = upass;
45. This. _ uname = uname;
46. }
47. // Verify whether the user has the right to access the internal interface
48. Private bool isValid (string uname, string upass, out string msg)
49. {
50. Msg = "";
51. If (uname = "admin" & upass = "admin ")
52. {
53. Return true;
54. }
55. Else {
56. Msg = "Sorry! You do not have permission to call this WebService! ";
57. Return false;
58. }
59. }
60. // Verify whether the user has the right to access the external interface
61. Public bool isValid (out string msg)
62. {
63. Return isValid (_ uname, _ password, out msg );
64. }
65. }
68. </Span>

2. Define the WebService to be verified.

1. <Span style = "font-size: 10px;"> using System;
2. Using System. Collections;
3. Using System. Linq;
4. Using System. Web;
5. Using System. Web. Services;
6. Using System. Web. Services. Protocols;
7. Using System. Xml. Linq;
9. /// <Summary>
10. /// Summary of test
11. /// </Summary>
12. [WebService (Namespace = "http://tempuri.org/")]
13. [WebServiceBinding (ConformsTo = WsiProfiles. BasicProfile1_1)]
14. // To allow ASP. net ajax to call this Web service from a script, cancel the comments to the downstream.
15. // [System. Web. Script. Services. ScriptService]
16. Public class test: System. Web. Services. WebService {
18. Public test (){
20. // If you use the designed component, uncomment the following line
21. // InitializeComponent ();
22. }
23. Public MySoapHeader myheader = new MySoapHeader ();
24. [WebMethod]
25. Public string HelloWorld () {// common WebService, no verification required
26. Return "Hello World ";
27. }
28. [SoapHeader ("myheader")] // the WebService with this header needs to be verified. If this header is not added, it is a common WebService and does not need to be verified.
30. [WebMethod (Description = "querying product prices by product number", EnableSession = true)]
32. Public string GetProductPrice2 (string ProductId)
33. {
35. String msg = "";
37. // Verify the access permission
39. If (! Myheader. isValid (out msg ))
40. {
42. Return-1; // return the error message
44. }
46. Return ProductId;
47. }
48. }
49. </Span>

3. Client call Method

Reference WebService definition WebService name: Myservice

1. <Span style = "font-size: 10px;"> using System;
2. Using System. Configuration;
3. Using System. Data;
4. Using System. Web;
5. Using System. Web. Security;
6. Using System. Web. UI;
7. Using System. Web. UI. HtmlControls;
8. Using System. Web. UI. WebControls;
9. Using System. Web. UI. WebControls. WebParts;
10. Public partial class _ Default: System. Web. UI. Page
11. {
12. Protected void Page_Load (object sender, EventArgs e)
13. {
14. Myservice. test te = new abc. test ();
15. Myservice. MySoapHeader myhead = new MySoapHeader ();
16. Myhead. Uname = "admin"; // enter the WebService access Username
17. Myhead. Password = "admin"; // enter the WebService Access Password
18. Te. MySoapHeaderValue = myhead ;//
19. String test = te. GetProductPrice2 ("OK! ");
20. Response. Write (aa); // if the user name and password are entered correctly, the output is OK; otherwise, the output is incorrect.
21. }
22. } </Span>
