Micro-micro-service gateway --- call other services

 

First, a write filter inherit ZuulFilter, and wherein the rewriting run () method, 

an access to information request object:

CTX = RequestContext.getCurrentContext the RequestContext (); 
the HttpServletRequest request ctx.getRequest = (); 
String servletPath request.getServletPath = (); 
information can be obtained after the get request object request:

String accessSys = request.getParameter("accessSys");
String paramData = getRequestBody(request);

private String getRequestBody(HttpServletRequest request) {
   try {
      InputStream v_inputstream = request.getInputStream();
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
      int x = 0;
      while ((x = v_inputstream.read()) != -1) {
         baos.write(x);
      }
      baos.flush();
      return new String(baos.toByteArray(), UTF_8);
   } catch (Exception e) {
      logger.error(e.getMessage(), e);
   }
   return "";
}

　2, the routing information in the routing routes traversing configuration information is as follows:

@ConfigurationProperties(prefix="application.myroutes")
public class MyRoutesConfig {

	
	private Map<String, String> routes;

	public Map<String, String> getRoutes() {
		return routes;
	}

	public void setRoutes(Map<String, String> routes) {
		this.routes = routes;
	}
}

Configuration files are as follows: 

# custom filter routes Reference: RestFaceFilter.java 
file application: 
   myroutes: 
     routes: { 
     -Service: 'ePassport-Platform', 
     ProxyService: 'ePassport-exservice' 
   }

 if (routes != null) {
            Set<String> keySet = routes.getRoutes().keySet();
            for (String str : keySet) {
//                logger.info("get route key: {}", str);
                if (servletPath.startsWith("/" + str + "/")) {
                    restface_forward = routes.getRoutes().get(str);
                    break;
                }
            }
        }
