以下是使用 Spring Boot 框架实现使用 API 密钥进行接口访问授权的示例代码:
1. 首先需要在 Spring Boot 应用程序中添加依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
```
2. 在 Spring Boot 应用程序中定义一个 Security 配置类,用于配置 API 访问授权规则:
```java
@Configuration
@EnableWebSecurity
public class ApiSecurityConfig extends WebSecurityConfigurerAdapter {
private static final String API_KEY_HEADER = "X-Api-Key";
private String[] allowedApiKeys = {"api-key-1", "api-key-2"};
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.antMatchers("/api/**").hasAnyAuthority(allowedApiKeys)
.anyRequest().permitAll()
.and()
.httpBasic();
}
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers(HttpMethod.OPTIONS);
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
for (String apiKey : allowedApiKeys) {
auth.inMemoryAuthentication()
.withUser(apiKey)
.password("{noop}")
.authorities(apiKey);
}
}
@Bean
public ApiKeyAuthFilter apiKeyAuthFilter() throws Exception {
return new ApiKeyAuthFilter(API_KEY_HEADER);
}
}
```
3. 定义一个 API Key 认证过滤器,用于检查 API Key 是否合法:
```java
public class ApiKeyAuthFilter extends OncePerRequestFilter {
private final String headerName;
public ApiKeyAuthFilter(String headerName) {
this.headerName = headerName;
}
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
String apiKey = request.getHeader(headerName);
if (StringUtils.isEmpty(apiKey)) {
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Missing API Key");
return;
}
if (!Arrays.asList("api-key-1", "api-key-2").contains(apiKey)) {
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Invalid API Key");
return;
}
filterChain.doFilter(request, response);
}
}
```
4. 在 Spring Boot 应用程序中注册 API Key 认证过滤器:
```java
@Configuration
public class ApiKeyFilterConfig {
@Bean
public FilterRegistrationBean<ApiKeyAuthFilter> apiKeyAuthFilterRegistration(ApiKeyAuthFilter filter) {
FilterRegistrationBean<ApiKeyAuthFilter> registrationBean = new FilterRegistrationBean<>();
registrationBean.setFilter(filter);
registrationBean.addUrlPatterns("/api/*");
registrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE);
return registrationBean;
}
@Bean
public ApiKeyAuthFilter apiKeyAuthFilter() {
return new ApiKeyAuthFilter("X-Api-Key");
}
}
```
5. 在 Spring Boot 应用程序中编写一个 API 接口,用于演示 API 访问授权:
```java
@RestController
@RequestMapping("/api")
public class ApiController {
@GetMapping("/hello")
public String hello() {
return "Hello, API!";
}
}
```
以上就是使用 Spring Boot 框架实现使用 API 密钥进行接口访问授权的示例代码。
