相关疑难解决方法(0)

我正在尝试使用Spring的RestTemplate进行跨源请求.通信是在两个Spring-boot webapps之间完成的,这两个webapp都运行在localhost但不同的端口上.我所做的是:

HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.setOrigin("http://localhost:8083");
httpHeaders.add("Authorization", token);

HttpEntity<Void> httpEntity = new HttpEntity<>(httpHeaders);

ParameterizedTypeReference<List<MyObj>> beanType = new ParameterizedTypeReference<List<MyObj>>() {};
ResponseEntity<List<MyObj>> list = restTemplate.exchange(serviceURL, HttpMethod.GET, httpEntity, beanType);

执行调用,"授权"标题传递得很好,但无论我尝试什么,接收端都没有"Origin"标题.当我使用其他工具(SoapUI,RestClient Chrome插件等)创建一个simillar请求时,标题就像我提供的那样传递.

要在接收端打印所有标头,我正在使用javax.servlet.Filter的实现:

public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)
        throws IOException, ServletException {
    HttpServletRequest request = (HttpServletRequest) req;
    HttpServletResponse response = (HttpServletResponse) res;
    Enumeration<String> headerNames = request.getHeaderNames();
    while (headerNames.hasMoreElements()) {
        String headerName = headerNames.nextElement();
        log.info(headerName + ": " + request.getHeader(headerName));
    }
}

使用RestTemplate时为什么不传递origin头？
