我正在尝试使用授权标头（基本auth）进行简单的get请求。

我正在使用Spring Boot（1.2.6.RELEASE），这也可能是相关的。我的CORS配置如下所示。

@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() {
}

}

这是客户端的外观

    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);
}

我不断得到：

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

请帮助，我不知道我要缺少什么…我已经检查了很多帖子，但无法到达那里…
