输入框，绑定了 <code>question</code> 变量，当我们输入的时候，会触发 <code>question</code> 的变化，执行 <code>watch question</code> 中的逻辑，执行 <code>this.debouncedGetAnswer</code> 方法，实际上就是 <code>debounce</code> 执行了 <code>getAnswer</code> 方法，发送请求。</p> <p>我们通过 <code>import axios from 'ts-axios-new'</code> 去加载 <code>ts-axios</code> 库，实际上就是引入了 <code>node_modules/ts-axios-new/dist/axios.es5.js</code>，因为 <code>ts-axios-new</code> 的 <code>package.json</code> 文件中配置的 <code>module</code> 字段是 <code>dist/axios.es5.js</code>，在 <code>webpack</code> 中优先 <code>import</code> 优先会找 <code>module</code> 字段，其次是 <code>main</code> 字段。</p> <blockquote><p>小技巧：当我们引入某个库运行时出现问题时候，我们就可以调试 node_modules 中对应引入的代码。</p></blockquote> <p>注意我们这里先使用了 <code>axios.create()</code> 方法创建了一个 <code>instance</code>，然后添加了一个请求拦截器，会在每次发送请求前，添加了一个 <code>_t</code> 参数，值为时间戳。然后执行 <code>instance.get</code> 发送一个请求。</p> <p>我们可以看到整个 demo 是可以正常运行的，并且没有任何类型相关的问题，说明我们的库打包后的代码和类型声明文件都是没有问题的。</p> <h2
