拦截器顾名思义，是在框架方法执行的各个环节（包含：拦截前触发、成功回调拦截、失败回调拦截、完成回调拦截）
|
||||
插入逻辑，篡改参数或终止运行。
|
||||
#### 优势
|
||||
- 这种方式相当于改写了api的内部逻辑，相比语法糖他更加直观，不影响ide的代码提示。
|
||||
- 将常规固定的逻辑封装到框架的api内，且支持个性化设计。如你可以在本插件路径:`/uni_modules/json-interceptor-chooseImage/js_sdk/main.js`修改弹出框元素，绘制更漂亮的样式和文字说明。
|
||||
|
||||
#### 使用示例，App.vue页代码如下：
|
||||
```
|
||||
<script>
|
||||
// #ifdef APP-PLUS
|
||||
import interceptorChooseImage from '@/uni_modules/json-interceptor-chooseImage/js_sdk/main.js';
|
||||
// #endif
|
||||
export default {
|
||||
onLaunch: function() {
|
||||
console.log('App Launch')
|
||||
// #ifdef APP-PLUS
|
||||
interceptorChooseImage()
|
||||
// #endif
|
||||
},
|
||||
onShow: function() {
|
||||
console.log('App Show')
|
||||
},
|
||||
onHide: function() {
|
||||
console.log('App Hide')
|
||||
}
|
||||
}
|
||||
</script>
|
||||
```
