Sitebricks :: CORE Frames' security and protection measures
Sitebricks is a lightweight web framework based on Google Guice, which aims to simplify building high -performance, safe and reliable web applications.This article will introduce the security and protective measures of the SiteBricks Core framework and provide examples of Java code.
1. Authentication and authorization
The SiteBricks Core framework provides a mechanism for authentication and authorization to ensure that users can only access its authoritative resources.Authentication can be implemented in different ways, such as forms based on forms and basic certifications of HTTP.The following is an example code based on form certification:
@At("/login")
public class Login {
@Inject
private Auth auth;
@Get
public Reply<Form> login() {
return Reply.with(new Form());
}
@Post
public Reply<Form> login(@In Form form) {
if (auth.authenticate(form.getUsername(), form.getPassword())) {
return Reply.saying().redirect("/dashboard");
} else {
return Reply.with(form).flash("error", "Invalid username or password");
}
}
}
public class Form {
private String username;
private String password;
// getters and setters
}
In the above code, `@at ("/login ")` annotations indicate that the request path of this type of processing is "/login", `@inject` annotations are used to inject instances of` auth`Post` annotations represent the processing of get and post requests, respectively.`AUTH` is responsible for authentication of identity, and authentication according to the username and password provided in the form.If the certification is successful, return to "/dashboard"; if the certification fails, return the login form with error messages.
Second, cross -site script attack (XSS) protection
The SiteBricks Core framework has an automatic HTML righteousness on the page output to prevent XSS attacks.This means that if you use the output method provided by the SiteBricks Core framework, there is no need to manually rotate HTML characters.The following is an example:
@At("/hello")
public class Hello {
@Post
@At("/:name")
public Reply<?> sayHello(@Named("name") String name) {
String message = "Hello, " + name + "!";
return Reply.with(message);
}
}
In the above code, `@at ("/hello ")` `Note indicates that the request path of this type of processing is"/hello ", and the annotation of`@post` indicates the processing request.`@At ("/: name ")` `` Name "name" variables in the URL path, such as "/Hello/World", "Name" will be bound to "World".In the `Sayhello` method,` Reply.with (Message) `will automatically turn the value of Message for HTML to prevent XSS attacks.
3. CSRF Protection
The SiteBricks Core framework provides a built -in CSRF protection mechanism, which can prevent cross -site request forged attacks.By default, Sitebricks Core will add a CSRF token to each form and verify the effectiveness of the token request for each post.The following is an example:
@At("/transfer")
public class Transfer {
@Inject
private CsrfToken csrfToken;
@Post
public Reply<?> transfer(@Header("X-Csrf-Token") String token, @Param("amount") double amount) {
if (csrfToken.isTokenValid(token)) {
// Treatment of transfer logic
return Reply.saying().ok();
} else {
return Reply.saying().unauthorized();
}
}
}
In the above code, `@at ("/transfer ")` annotations indicate that the request path for this type of processing is "/transfer", and `@inject` annotations are used to inject instances of` CSRFTOKEN`.In the `Transfer` method, the CSRF token in the request head is injected into the` token` parameter through the note through the `@Header (" X-CSRF-TOKEN ")` `` `Then use the `CSRFTOKEN.ISTOKENVALID (token)` method to verify the effectiveness of the token. If valid, process the transfer logic, otherwise the unauthorized response will be returned.
In summary, the Sitebricks Core framework provides security characteristics such as authentication, authorization, XSS protection, and CSRF protection, which can help developers build safe and reliable web applications.
