@upload-success="onUploadSuccess"
@upload-error="onUploadError"
>
<button slot="browse">选择文件</button>
</vue-simple-uploader>
</div>
</template>
<script>
import VueSimpleUploader from 'vue-simple-uploader';
export default {
components: {
VueSimpleUploader,
},
data() {
return {
uploadUrl: 'http://example.com/upload',

示例1:使用Vue-Simple-Uploader上传单个文件
以下是使用Vue-Simple-Uploader上传单个文件的示例:
<template>
<div>
<vue-simple-uploader
ref="uploader"
:uploadUrl="uploadUrl"
:headers="headers"
:params="params"
:multiple="false"
:accept="accept"
:maxSize="maxSize"
:maxFiles="1"
:autoUpload="autoUpload"
:withCredentials="withCredentials"
@upload-success="onUploadSuccess"
@upload-error="onUploadError"
>
<button slot="browse">选择文件</button>
</vue-simple-uploader>
</div>
</template>
<script>
import VueSimpleUploader from 'vue-simple-uploader';
export default {
components: {
VueSimpleUploader,
},
data() {
return {
uploadUrl: 'http://example.com/upload',
headers: {
Authorization: 'Bearer ' + localStorage.getItem('token'),
},
params: {
userId: 123,
},
multiple: false,
accept: 'image/*',
maxSize: 1024 * 1024 * 10, // 10MB
maxFiles: 1,
autoUpload: true,

},
methods: {
onUploadSuccess(response) {
console.log('Upload success:', response);
},
onUploadError(error) {
console.error('Upload error:', error);

},
};
</script>
上述代码中,程序设置了multiple为false,maxFiles为1,表示只能上传单个文件。其他属性和事件处理函数与前面的示例相同。
示例2:使用Vue-Simple-Uploader上传多个文件

:multiple="true"
:accept="accept"
:maxSize="maxSize"
:maxFiles="maxFiles"

</vue-simple-uploader>
</div>
</template>
<script>
import VueSimpleUploader from 'vue-simple-uploader';
