I'm trying to debug my web app, I have a POST request. (using ajax, with xhrFields: { withCredentials: true } ). dataType is 'application/json', my server is tomcat and i set my "Access-Control-Allow-Origin" header manually to "http://localhost:8080".
other headers: response.addHeader("Access-Control-Allow-Credentials", "true"); response.addHeader("Access-Control-Allow-Headers", "x-request-verification-token");
Cant get this to work. this is the error i get:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8080/MysServlet. (Reason: CORS header 'Access-Control-Allow-Origin' does not match 'http://localhost:8080').
thanks ahead!
If you want a configuration that apply to all your requests add in your web.xml the following filter:
<filter>
<filter-name>originfilter</filter-name>
<filter-class>it.damore.web.ApiOriginFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>originfilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
This is the ApiOriginFilter class:
public class ApiOriginFilter implements javax.servlet.Filter {
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
HttpServletResponse res = (HttpServletResponse) response;
res.addHeader("Access-Control-Allow-Origin", "*");
res.addHeader("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT");
res.addHeader("Access-Control-Allow-Headers", "Content-Type");
chain.doFilter(request, response);
}
public void destroy() {
}
public void init(FilterConfig filterConfig) throws ServletException {
}
}
