Question

在处理基于UDP的java项目时，我遇到了一个非常奇怪的问题。总结一下，当我通过DataPacket收到请求时，我将其转换为新的字符串，然后当我去检查字符串值时，它继续返回false。代码如下。

<ion-side-menus>

  <ion-side-menu side="left">

            <!--**** This works**** -->
<ion-header-bar  ng-class="myvar">
  <h1 class="title">Menu</h1>
</ion-header-bar>

    <ion-content>
        <ion-list>
          ...
        </ion-list>
    </ion-content>

  </ion-side-menu>

  <ion-side-menu-content>

          <!--**** This doesn't work**** -->
    <ion-nav-bar ng-class="myvar" >
          <!--**** If i change it for class={{myvar}}, it doesn't refresh**** -->
             ...
    </ion-nav-bar>
    <ion-nav-view name="menuContent"></ion-nav-view>
  </ion-side-menu-content>
</ion-side-menus>

尝试修剪你的信息，也许它包含空格。

    DatagramPacket request = new DatagramPacket(buffer, buffer.length);
    aSocket.receive(request);
    String message = new String(request.getData()).trim();
    System.out.println("Received: " + new String(request.getData()));
    System.out.println(message); //Prints out "11" without quotes when I send it
    String a = "11";
    System.out.println("Received: " + message);
    if(message.equals("11")){
        System.out.println("Got 11.");
    }
