春季安全性，启用Oauth2时出现cors错误

查询我的oauth / token端点时出现错误。

我已经为我的资源配置了cors enable，也尝试允许所有资源，但是没有任何作用。

XMLHttpRequest无法加载http：// localhost：8080 / oauth /

token。对预检请求的响应未通过访问控制检查：请求的资源上不存在“

Access-Control-Allow-Origin”标头。因此，不允许访问源’ http：//

localhost：1111 ‘。响应的HTTP状态码为401。

有了邮递员，一切都完美无缺。

我的cors安全性配置：

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedHeaders("*")
                .allowedMethods("*")
                .allowCredentials(true);
    }
}

还尝试在允许的来源中添加http：// localhost：1111

邮递员中的代码：

require 'uri'
require 'net/http'
url = URI("http://localhost:8080/oauth/token")
http = Net::HTTP.new(url.host, url.port)
request = Net::HTTP::Post.new(url)
request["content-type"] = 'application/x-www-form-urlencoded'
request["authorization"] = 'Basic Y2hhdHRpbzpzZWNyZXRzZWNyZXQ='
request["cache-control"] = 'no-cache'
request["postman-token"] = 'daf213da-e231-a074-02dc-795a149a3bb2'
request.body = "grant_type=password&username=yevhen%40gmail.com&password=qwerty"
response = http.request(request)
puts response.read_body

回答：

经过很多努力后，我重写了类 WebSecurityConfigurerAdapter的configure（WebSecurity web）方法

，因为授权服务器自行配置了此方法，而我还没有找到其他解决方案。另外，您还需要允许所有“ /oauth/token”Http.Options方法。我的方法：

__

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers(HttpMethod.OPTIONS, "/oauth/token");
}

此后，我们需要添加cors过滤器以将Http状态设置为OK。现在我们可以感知Http.Options方法了。

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
@WebFilter("/*")
public class CorsFilter implements Filter {
    public CorsFilter() {
    }
    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        final HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with, authorization");
        response.setHeader("Access-Control-Max-Age", "3600");
        if ("OPTIONS".equalsIgnoreCase(((HttpServletRequest) req).getMethod())) {
            response.setStatus(HttpServletResponse.SC_OK);
        } else {
            chain.doFilter(req, res);
        }
    }
    @Override
    public void destroy() {
    }
    @Override
    public void init(FilterConfig config) throws ServletException {
    }
}
