vue的图片上传

关于vue3的图片上传，这里记录一下，有兴趣的朋友可以参考。。。。
 

 <van-uploader:after-read="afterRead"v-model="headImg":max-count="1"class="picture"/>

const fileList = ref();const afterRead = (file) => {let img = file.file;const form = new FormData();form.append("file", img, img.name);console.log(file, 123456);File(form, { id: 23 }).then((arr) => {console.log(arr);fileList.value = arr.data.url;console.log(fileList.value);}).catch((err) => {console.log(err);});
};const headImg = ref([]);
function publish() {console.log(item);console.log(uid.id);console.log(number.value);console.log(content.value);Scenicom({scenic_id: item,user_id: uid.id,score: number.value,content: content.value,img: fileList.value,},{ id: 23 }).then((arr) => {showSuccessToast("评论成功");console.log(arr);}).catch((err) => {console.log(err);});
}
// 假设您有一个方法来检查图片是否已上传  
function isImageUploaded() {  return fileList.value !== null && fileList.value !== undefined;  
}
