title: Multiple Parameters in React Router
body: <p>my application works fine with one parameter - id. How do I add more parameters in the routes, for example, campus, subject, etc. ?</p>
  
  <pre><code> const Routing = () =&gt; ( 
      &lt;HashRouter&gt;
        &lt;Route path='/course/:id' component={Parameters} /&gt; 
        &lt;Route path='/course/:CAMPUS_NAME' component={Campus} /&gt;
        &lt;Route  path="/" component={App} /&gt;
      &lt;/HashRouter&gt;
    &lt;/&gt;
  );
  
  export default Routing;
  </code></pre>
  
  <p>Parameters.js</p>
  
  <pre><code>...
  componentDidMount(){
                const {id} = this.props.match.params.id ;            
                  this.runSearch();          
    }
  ...
  </code></pre>
