vue element-ui 文件上傳

<el-upload class="upload-demo" action="" :before-remove="beforeRemove" :on-remove="onRemove" multiple :limit="1" :on-exceed="handleExceed" :file-list="fileList" :http-request="uploadSectionFile">
    <el-button size="small" type="primary">點擊上傳</el-button>
    <!-- <div slot="tip" class="el-upload__tip">只能上傳jpg/png文件，且不超過500kb</div> -->
</el-upload>

 

js

接口：

export const uploadFile = params => {
    return axios.post(`${easykp_config.test}/file/upload`, params, { headers: { 'author-token-key': localStorage.getItem('token') } }).then(res => res.data);
};

 

調用：

//文件上傳
        handleExceed(files, fileList) { //超出限制
            this.$message.warning(`當前限制選擇 1 個文件，本次選擇了 ${files.length} 個文件，共選擇了 ${files.length + fileList.length} 個文件`);
        },
        beforeRemove(file, fileList) { //肯定移除

            return this.$confirm(`肯定移除 ${ file.name }？`);
        },
        onRemove(file, fileList) { //刪除清空
            // console.log(file, fileList)
            this.filesId = [];
        },
        uploadSectionFile(param) {
            var fileObj = param.file;
            var formData = new FormData();
            formData.append('file', fileObj);
            // console.log('formData',fileObj.size)可作大小限制等
            uploadFile(formData).then((res) => { //請求數據
                if (res.code == 200) {
                    this.filesId.push(res.body.id);
                    this.$message.success(`上傳成功`);
                } else {
                    this.$message({
                        message: res.message,
                        type: 'error'
                    });
                }
            });
        }
