vue上传文件已经不陌生了,这次主要看python 后端如何接受和element 上传过程有什么注意的

1.前端

<el-upload
                        :limit=limitNum
                        :auto-upload="false"
                        accept=".xlsx"
                        action=""
                        :before-upload="beforeUploadFile"
                        :on-change="fileChange"
                        :on-exceed="exceedFile"
                        :on-remove="removeFile"
                        :file-list="fileList">
                    <el-button  v-if="showFile" type="primary" >选择文件</el-button>
                </el-upload>

    limitNum: 1,  // 上传excell时，同时允许上传的最大数
                fileList: [],   // excel文件列表
                showImport:false,
                showFile:true,
       //文件超出个数限制时的钩子
            exceedFile(files, fileList) {
                // this.$Message.warning(`只能选择 ${this.limitNum} 个文件，当前共选择了 ${files.length + fileList.length} 个`);
                console.log("文件超出个数限制");
            },
            //删除文件钩子
            removeFile() {
                this.fileList=[]
            },
            // 文件状态改变时的钩子
            fileChange(file, fileList) {
                console.log("file change");
                this.fileList=[];
                this.fileList.push(file.raw);
                this.showImport = true;
                // this.showFile = false;
            },
            beforeUploadFile: function (file) {
                //限制的上限为10M
                const isLt10M = file.size / 1024 / 1024 < 5;
                if (isLt10M) {
                    this.uploadFile();
                } else {
                    this.$Message.error('上传文件大小不能超过 5MB!');
                }
                return isLt10M;
            },
            uploadFile() {
                //显示遮罩
                this.listLoadings = true;

                if (this.fileList.length === 0) {
                    this.$message.warning('请选择上传文件');
                } else {
                    let formData = new FormData();
                    formData.append('file', this.fileList[0]);
                    formData.append('project_id', this.$route.params.project_id);
                      $.ajax({
                        type: "post",
                        url: test + "/api/automation/up_case",
                        async: false,
                        data: formData,
                        dataType:"json", //data格式比较重要
                        // ajax2.0可以不用设置请求头，但是jq帮我们自动设置了，这样的话需要我们自己取消掉
                        contentType:false,
                        //取消帮我们格式化数据，是什么就是什么
                        processData:false,
                        headers: {
                            Authorization: 'Token ' + JSON.parse(sessionStorage.getItem('token')),
                        },
                        timeout: 5000,
                        success: function (data) {
                            let self = this;
                            if (data.code === '999999') {
                                self.showDel = true;
                                self.showModify = true;
                                self.getCaseList();
                                self.getHost();
                                self.listLoadings = false;
                                self.showImport = false;
                            } else {
                                self.listLoadings = false;
                                self.$message.error({
                                    message: data.msg,
                                    center: true,

                                })
                            }
                        },
                    })

                }
            },

2.后端接收

    def post(self, request):
        """
        获取用例下载文档路径
        :param request:
        :return:
        """
        project_id = request.POST.get('project_id')
        obj = Project.objects.get(id=project_id)
        # 获取前台传入的文件
        uploadedFile = request.FILES.get('file')
        # 获取execl文件
        wb = load_workbook(uploadedFile)
        # 取第一张表
        sheetnames = wb.get_sheet_names()
        ws = wb.get_sheet_by_name(sheetnames[0])
        # 建立存储数据的字典
        data_list = []
        row_first = ws.max_row  # 行数
        # rows = ws.rows
        print(ws.max_column)  # 列数
        cel_num = dict()
