Python+Flask(3)测试使用ueditor实现富文本图片上传

先看最终实现效果图:

 

 实现步骤如下:

1.网上下载ueditor

        下载地址:http://ueditor.baidu.com/website/download.html#ueditor​

2.项目目录结构如下:

 3.重点文件代码:

         1)app.py

from flask import Flask,render_template
from ueditor import bp
import config
app = Flask(__name__)
app.config.from_object(config)
app.register_blueprint(bp)

@app.route('/')
def index():
    return render_template('index.html')

if __name__ == '__main__':
    app.run(port=9000,debug=True)

2)config.py

import os

#上传到本地
UEDITOR_UPLOAD_PATH = os.path.join(os.path.dirname(__file__), 'static\\images')

3)ueditor.py

    letters = string.ascii_letters

    subffix = os.path.splitext(rawfilename)[-1]
    return filename + subffix

    result = {}
    if action == 'config':

        }
        image.save(os.path.join(UEDITOR_UPLOAD_PATH, save_filename))
        result['state'] = "SUCCESS"
        result['url'] = url_for('ueditor.files', filename=save_filename)
        result['title'] = save_filename
        result['original'] = save_filename

    elif action == 'uploadscrawl':#执行上传涂鸦的action名称
        base64data = request.form.get("upfile")

        }

    return jsonify(result)

@bp.route('/files//')
def files(filename):
    return send_from_directory(UEDITOR_UPLOAD_PATH,filename)
