vue js 代码

changeFile(file, fileList) {
      this.fileList = fileList; // 再一次赋值
    },
    removeFile(file, fileList) {
      this.fileList = fileList; // 再一次赋值
    },
    submitUpload(id) {
        let formData = new FormData()
        for (let i = 0; i < this.fileList.length; i++) {
          formData.append("files", this.fileList[i].raw) // formdata 添加数组的独特方式
        }
        formData.append("id", id)
        formData.append("type", 'image')
        formData.append("typeClass", "sourceCode")
        let self = this
        this.$axios({
          method: 'post',
          url: '/upload',  // 后端接口地址
          headers: {'Content-Type': 'multipart/form-data'},
          data: formData
        }).then((res) => {
          debugger
          if (res.data == "success") {
            self.$message({
              showClose: true,
              message: "项目截图上传成功",
              type: "success",
              duration: 5000,
            });
          }
        }).catch(function (ex) {
          console.error(ex)
         self.$message({
              showClose: true,
              message: "上传失败",
              type: "error",
              duration: 5000,
            });
        });
    }

python  代码：

 @app.route('/file/upload', methods=['POST'])
    def fileUpload():
        data = request.form

        base = app.config['IMG_ROOT']
        for f in request.files.getlist("files"):
            fi = File()
            t = time.time()
            ...
        return 'success'
