接口：
export const uploadFile = params => { return axios.post(`${easykp_config.test}/file/upload`, params, { headers: { 'author-token-key': localStorage.getItem('token') } }).then(res => res.data); }; 调用：
//文件上传 handleExceed(files, fileList) { //超出限制 this.$message.warning(`当前限制选择 1 个文件，本次选择了 ${files.length} 个文件，共选择了 ${files.length + fileList.length} 个文件`); }, beforeRemove(file, fileList) { //确定移除 return this.$confirm(`确定移除 ${ file.name }？`); }, onRemove(file, fileList) { //删除清空 // console.log(file, fileList) this.filesId = []; }, uploadSectionFile(param) { var fileObj = param.file; var formData = new FormData(); formData.append('file', fileObj); // console.log('formData',fileObj.size)可做大小限制等 uploadFile(formData).then((res) => { //请求数据 if (res.code == 200) { this.filesId.push(res.body.id); this.$message.success(`上传成功`); } else { this.$message({ message: res.message, type: 'error' }); } }); } 具体详见官方api,很详细
