纠错比例 +- 通过设置 `errorLevel` 调整不同的容错等级。 + +```html + +``` + +#### 生成图片 +- 1、通过调用插件的`canvasToTempFilePath`方法生成图片。 + +```html + + + +``` +```js +// vue3 +const qrcodeRef = ref(null) +const onClick = () => { + if(!qrcodeRef.value) return + qrcodeRef.value.canvasToTempFilePath({ + success(res) { + image.value = res.tempFilePath + console.log('success:::', res) + }, + fail(err) { + console.log('err:::',

res.tempFilePath + }, + fail(err: TakeSnapshotFail) { + console.log('err:::', err) + } +}) +``` + +- 2、通过设置`useCanvasToTempFilePath`在`success`事件里接收图片地址 + +```html + + +``` +```js +const image = ref(null) +const success = (img) => { + image.value = img +} +``` + +### 关于vue2的使用方式 +- 插件使用了`composition-api`,

VueCompositionAPI from '@vue/composition-api' +Vue.use(VueCompositionAPI) +``` +另外插件也用到了TS，vue2可能会遇过官方的TS版本过低的问题,找到HX目录下的`compile-typescript`目录 +```cmd +// \HBuilderX\plugins\compile-typescript +yarn add typescript -D +- or - +npm install typescript -D +``` + +### 查看示例 +- 导入后直接使用这个标签查看演示效果 + +```html +// 代码位于 uni_modules/lime-qrcode/compoents/lime-qrcode + +``` + +### 插件标签 +- 默认 l-qrcode 为
