最近工作中用到Vue.js加上一直在用的Flask,所以準備寫個小小的demo鞏固下。

ps：之前一直用unpkg的各種包，發(fā)現會出問題，所以demo中將所有需要用到的js包放在本地當中。

項目使用到Flask+flask_jsglue+vue.js+element-ui+data-table.js+axios.js

demo很簡單，最基本的flask應用加上幾個api方法

index.py:

app = Flask(__name__)
jsglue = JSGlue()
jsglue.init_app(app) # 讓js文件中可以使用url_for方法
@app.route('/')
def index():
    return render_template('index.html')
@app.route('/get_data')
def get_base_data():
    return jsonify({'results': results})
@app.route('/add', methods=['POST'])
def add():
    name = request.json.get('name')
    results.append({'name': name, 'index': str(uuid1())})#uuid讓index不唯一，實際開發(fā)中可以通過數據庫的id來代替
    return jsonify({'message': '添加成功！'}), 200
@app.route('/update', methods=['PUT'])
def update():
    name = request.json.get('name')
    index = request.json.get('index')
    for item in results:
        if item['index'] == index:
            item['name'] = name
            break
    return jsonify({'message': '編輯成功！'}), 200
@app.route('/delete', methods=['DELETE'])
def delete():
    name = request.args.get('name')
    index = request.args.get('index')
    results.remove({'name': name, 'index': index})
    return jsonify({'message': '刪除成功！'}), 200
if __name__ == '__main__':
    app.run(debug=True)

template

因為demo比較簡單，數據存在內存中，僅僅用于展示，讀者可自行結合數據庫
