flask-uploads上传插件上传文件

安装插件：
pip install flask-uploads
创建上传文件对象：
from flask_uploads import UploadSet
#在这里限制允许上传类型
from flask_uploads import TEXT,IMAGES
uploads=UploadSet(“UPLOADS”,extensions=TEXT+IMAGES)

导出
from .ext_uploads import uploads
加载三方对象 在app.py
from exts import uploads
from flask_uploads import configure_uploads
from flask_uploads import patch_request_class

configure_uploads(app,uploads)
#配置上传文件的大小,默认64M,size也可以设置None,这时会读取配置文件中的MAX_CONTENT_LENGTH里面的值
#patch_request_class(app,size=None)
patch_request_class(app,210241024)
配置

备注：BASE_DIR=os.path.dirname(os.path.dirname(os.path.abspath(file)))#是工程目录

if request.method==“GET”:
return render_template(“upfile.html”)
