官网给的例子action都是绝对地址，我现在需要上传到自己后台的地址，只有一个路由地址/task/upload

根据 config/index.js配置，那么action要写成/api/task/upload，另外也可以传入函数来返回地址:action="uploadUrl()"。

另外一个问题就是此插件不会默认带上token，需要手动传递。

<el-upload class="upload-demo" action="/api/task/upload" :multiple="false" name="jarfile" :file-list="fileList"accept="application/java-archive" :on-success="onUploadSuccess" :headers="{'Auth-Token': tokenValue}"><el-button size="small" type="primary">点击上传</el-button><span slot="tip" class="el-upload__tip" style="margin-left: 10px;">不要重复上传文件，按需上传</span>
</el-upload>

<script>import store from '@/store'export default {data() {return {tokenValue: store.getters.user.token,fileList: []}},computed: {},components: {},created() {},methods: {onUploadSuccess(response, file, fileList) {this.fileList = []if (response.code === 0) {this.form.command = response.data// this.fileList = [{ name: response.data, url: response.data, status: 'success' }]} else {this.$message.error(response.message)}}}
}
</script>
