Hi,

I was working on below challenge again

http://codingbat.com/prob/p151359
public String withoutX2(String str) {
  
  if(str.length()==1&&str.charAt(0)=='x'){
    return "";
  }
  if(str.length()>=2){
  if ( str.charAt(0)=='x' && str.charAt(1)=='x' ){
  return str.substring(2);
  }else if(str.charAt(0)=='x'){
      return str.substring(1);
  }else if(str.charAt(1)=='x'){
      return str.substring(0,1)+str.substring(2);
  }
  }
  return str;
}

Open in new window

below code passes all tests
Expected      Run            
withoutX2("xHi") → "Hi"      "Hi"      OK      
withoutX2("Hxi") → "Hi"      "Hi"      OK      
withoutX2("Hi") → "Hi"      "Hi"      OK      
withoutX2("xxHi") → "Hi"      "Hi"      OK      
withoutX2("Hix") → "Hix"      "Hix"      OK      
withoutX2("xaxb") → "axb"      "axb"      OK      
withoutX2("xx") → ""      ""      OK      
withoutX2("x") → ""      ""      OK      
withoutX2("") → ""      ""      OK      
withoutX2("Hello") → "Hello"      "Hello"      OK      
withoutX2("Hexllo") → "Hexllo"      "Hexllo"      OK      
withoutX2("xHxllo") → "Hxllo"      "Hxllo"      OK      
other tests
OK      

But if i have input say z what would be output and my code fails in that scenario right

withoutX2("z") → z
public class WithoutX2 {

	public static void main(String[] args) {
		
		// TODO Auto-generated method stub
		System.out.println("Value is"+withoutX2("z"));//should get true but getting false
	}
	
	public static String withoutX2(String str) {
		  
		  if(str.length()==1&&str.charAt(0)=='x'){
		    return "";
		  }
		  if(str.length()>=2){
		  if ( str.charAt(0)=='x' && str.charAt(1)=='x' ){
		  return str.substring(2);
		  }else if(str.charAt(0)=='x'){
		      return str.substring(1);
		  }else if(str.charAt(1)=='x'){
		      return str.substring(0,1)+str.substring(2);
		  }
		  }
		  return str;
		}

I am trying to call REST services deployed on Tomcat 8 from Angular 4. Since both these are running on separate domains, CORS issue is expected. So, in the tomcat/conf/web.xml, I have added the below filter
<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
  <init-param>
    <param-name>cors.allowed.origins</param-name>
    <param-value>*</param-value>
  </init-param>
  <init-param>
    <param-name>cors.allowed.methods</param-name>
    <param-value>GET,POST,HEAD,OPTIONS,PUT</param-value>
  </init-param>
  <init-param>
    <param-name>cors.allowed.headers</param-name>
    <param-value>Content-Type,X-Requested-With,accept,Origin,Access-Control-Request-Method,Authorization,Access-Control-Request-Headers</param-value>
  </init-param>
  <init-param>
    <param-name>cors.exposed.headers</param-name>
    <param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
  </init-param>
</filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

Open in new window


This is how I am sending the GET request from Angular
var basicOptions:RequestOptionsArgs = {
  url: 'http://server3:7000/myrest/info',
  method: RequestMethod.Get,
  search: null,
  headers: new Headers(
    {'Authorization': 'Basic AG1hZG1pbjpkZW1vLmRlbW8=' },
    ),
  body: null
};

basicOptions.headers.append('Content-Type', 'application/json');

var reqOptions = new RequestOptions(basicOptions);
var req = new Request(reqOptions);
return this.http.request( req );

Open in new window


Since, I am sending the Authorization header, it is also added in the 'cors.allowed.headers' param in Tomcat.

When I call the REST service from Chrome, it always gives me a 'Invalid CORS request' error (Network tab -> Preview). Below is the error in browser console
XMLHttpRequest cannot load http://server3:7000/myrest/info. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 403.

Is there something else that I need to do to make it work?
