一、SpringBoot
增加类CORSFilter
@Configuration
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CORSFilterimplements Filter {
private FilterConfigconfig;
public static final StringCREDENTIALS_NAME ="Access-Control-Allow-Credentials";
public static final StringORIGIN_NAME ="Access-Control-Allow-Origin";
public static final StringMETHODS_NAME ="Access-Control-Allow-Methods";
public static final StringHEADERS_NAME ="Access-Control-Allow-Headers";
public static final StringMAX_AGE_NAME ="Access-Control-Max-Age";
@Override
public void destroy() {
}
@Override
public void doFilter(ServletRequest req, ServletResponse resp,
FilterChain chain)throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) resp;
HttpServletRequest request = (HttpServletRequest) req;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "x-requested-with, authorization, Content-Type, Authorization, credential, X-XSRF-TOKEN");
if ("OPTIONS".equalsIgnoreCase(request.getMethod())) {
response.setStatus(HttpServletResponse.SC_OK);
}else {
chain.doFilter(req, resp);
}
}
@Override
public void init(FilterConfig filterConfig)throws ServletException {
config = filterConfig;
}
}
二、SpringCloud
在Gate Application中增加
@Bean
public CorsFiltercorsFilter() {
final UrlBasedCorsConfigurationSource source =new UrlBasedCorsConfigurationSource();
final CorsConfiguration config =new CorsConfiguration();
config.setAllowCredentials(true); // 允许cookies跨域
config.addAllowedOrigin("*");// #允许向该服务器提交请求的URI，*表示全部允许，在SpringMVC中，如果设成*，会自动转成当前请求头中的Origin
config.addAllowedHeader("*");// #允许访问的头信息,*表示全部
config.setMaxAge(18000L);// 预检请求的缓存时间（秒），即在这个时间段里，对于相同的跨域请求不会再预检了
config.addAllowedMethod("OPTIONS");// 允许提交请求的方法，*表示全部允许
config.addAllowedMethod("HEAD");
config.addAllowedMethod("GET");// 允许Get的请求方法
config.addAllowedMethod("PUT");
config.addAllowedMethod("POST");
config.addAllowedMethod("DELETE");
config.addAllowedMethod("PATCH");
source.registerCorsConfiguration("/**", config);
return new CorsFilter(source);
}
