Vue+Flask实现图片传输功能

//这是封装的请求
export const upload = (file) => {
  return request({
    url: "/api/uavprp/upload",
    data: file,
    method: "post",
    headers: { 
      "Content-Type": "multipart/form-data"
     },
  })
}

#请求中获取到上传的图片
a = request.files.get("file")
#限制文件后缀名必须为图片的类型
allowed_filename = set(["png", "jpg", "JPG", "PNG"])
isallowed = "." in filename and filename.rsplit(".", 1)[1] in allowed_filename
path = basedir + "/image/"  #这里的image是自己创建的保存图片文件夹路径
img_name = change_file_name(a.filename,ImgID)#这是我自己定义的一个方法 为了修改图片的名字为随机生成的唯一ID，同时不修改后缀名
file_path = path + img_name#完整的保存路径加图片名
a.save(file_path)#保存

//封装的图片请求
export const getImg = (imgID) => {
  return request({
    url: "/api/ferchoosen/getFerImg",
    method: "get",
    responseType:"blob",
    params: {
      imgID
    }
  })
}

imgID = request.args["imgID"]
    if imgID == None:
        return output(msg="该图片不存在")
    path = basedir + "/image/"
    image_data = open(os.path.join(path, "%s" % imgID), "rb").read()
    respOnse= make_response(image_data)
    response.headers["Content-Type"] = "image/png"#返回的内容类型必须修改
    return response
