vue3 文件转base64

在Vue3中,可以使用以下代码将文件转换为Base64:
```javascript
async function fileToBase64(file) {
return new Promise((resolve, reject) => {
const reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = () => {
resolve(String(reader.result));
};
reader.onerror = (error) => {
reject(error);
};
});
}
```
这个函数接受一个文件作为参数,将文件转换为Base64格式,并返回一个Promise对象。你可以在你的Vue3组件中调用这个函数,如下所示:
```javascript
fileToBase64(param.file).then((base64) => {
// 将base64赋值给你需要的变量
});
```
请注意,你需要将`param.file`替换为你实际的文件对象。通过调用`fileToBase64`函数,你可以将文件转换为Base64格式并在Vue3中使用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
