预检的响应具有无效的HTTP状态代码401 - Spring [英] Response for preflight has invalid HTTP status code 401 - Spring

问题描述

大家。
我是Angular 2和Spring Framework的新手。
我正在尝试一个带有授权头（基本auth）的简单的get请求。

everyone. I'm new to Angular 2 and Spring Framework. I'm trying a simple get request with an authorization header (basic auth).

我使用Spring Boot（1.2.6.RELEASE）这也可以是相关的。
我的CORS配置看起来像这样。

I'm using Spring Boot (1.2.6.RELEASE), which can also be relevant. My CORS configuration looks like this.

@Component
public class SimpleCorsFilter implements Filter {

private final Logger log = LoggerFactory.getLogger(SimpleCorsFilter.class);

public SimpleCorsFilter() {
    log.info("SimpleCORSFilter init");
}

@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {

    HttpServletRequest request = (HttpServletRequest) req;
    HttpServletResponse response = (HttpServletResponse) res;

    response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));
    response.setHeader("Access-Control-Allow-Credentials", "true");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me, authorization, x-auth-token");

    chain.doFilter(req, res);
}

@Override
public void init(FilterConfig filterConfig) {
}

@Override
public void destroy() {
}

}

喜欢从客户端

    this.headers.append('Authorization', 'Basic dXNlcjphZG1pbg==');
    return this.http
            .get(`http://localhost:8080/api/login?username=${username}`, {headers : this.headers} )
            .map(response => response.json().data as any);
}

我得到：

XMLHttpRequest无法加载
http：// localhost ：8080 / api / login？username = user 。对预检的响应
具有无效的HTTP状态代码401

XMLHttpRequest cannot load http://localhost:8080/api/login?username=user. Response for preflight has invalid HTTP status code 401

请帮助，我不知道我错过了什么。 ..
我检查了很多帖子已经，但不能到那里...

Please help, i don't know what i'm missing... I checked around a lot of posts already but couldn't get there...

推荐答案

并在http方法为OPTIONS时设置状态200

avoid filtering and set status 200 when http method is OPTIONS

if("OPTIONS".equalsIgnoreCase(request.getMethod())) {
    response.setStatus(HttpServletResponse.SC_OK);
} else {
    chain.doFilter(req, res);
}
