#先导入次此处需要用到的库：
from flask_uploads import UploadSet, IMAGES, configure_uploads, ALL,patch_request_class# 配置文件上传到的路径，以及限制上传文件的类型
app.config['UPLOADED_PHOTO_DEST'] = os.path.dirname(os.path.abspath(__file__))
app.config['UPLOADED_PHOTO_ALLOW'] = IMAGES# 实例化 UploadSet 对象
photos = UploadSet('PHOTO')# 将 app 的 config 配置注册到 UploadSet 实例 photos
configure_uploads(app, photos)photo.py
from flask import Blueprint,jsonify,render_template,request
from flask import request, Flask, redirect, url_for, render_template,abortimport os
from app import cache, photosphoto = Blueprint('photo', __name__)# 上传图片页央
@photo.route("/upload/", methods=['GET'])
def photo_upload():# 得到post参数return render_template('photo/upload.html')# 接收上传图片
@photo.route("/uploaded/", methods=['POST'])
def photo_uploaded():# 得到post参数filename = photos.save(request.files['photo'])return redirect(url_for('photo.photo_show', name=filename))@photo.route("/show/<name>", methods=['GET'])
def photo_show(name):if name is None:abort(404)url = photos.url(name)return render_template('photo/show.html', url=url, name=name)upload.html
