Bootstrap 3 发生了很多变化。您需要指定输入的宽度。您可以尝试类似...

<div class="navbar navbar-fixed-top">
      <div class="container">
        <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".nav-collapse">
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand" href="#">Brand</a>
        <div class="nav-collapse collapse">
          <ul class="nav navbar-nav pull-right">
            <li class="dropdown">
              <a href="#" class="dropdown-toggle" data-toggle="dropdown">User <b class="caret"></b></a>
              <ul class="dropdown-menu">
                <li><a href="#">Action</a></li>
                <li><a href="#">Another action</a></li>
                <li><a href="#">Something else here</a></li>
                <li class="divider"></li>
                <li class="nav-header">Nav header</li>
                <li><a href="#">Separated link</a></li>
                <li><a href="#">One more separated link</a></li>
              </ul>
            </li>
          </ul>
          <form class="navbar-form">
            <button type="submit" class="btn btn-default glyphicon glyphicon-search"></button> 
            <input type="search" class="form-control pull-left" style="width:70%;"> 
          </form>
        </div><!--/.nav-collapse -->
      </div>
    </div>
