request.form和request.args.get的区别

1、若get请求改为post请求,那么我们在后台使用request.args访问参数id的值,

使用request.form访问params参数集中各参数的值

例如:

前端代码:

<form method="post">
        <tr>
            昵称<input type="text" style="text-align:center" id="username" name="username" maxlength="8" {% if user_list %} value="{{ user_list.username }}" {% endif %}/>
        </tr>

        <tr>
            真实名字<input type="text" style="text-align:center" id="realname" name="realname" maxlength="20" {% if user_list %} value="{{ user_list.realname }}" {% endif %}/>
        </tr>
        <tr>
            &nbsp
        </tr>

        <tr>
            <button type="submit" id="not_null" style="display: none">确定</button>
            <button type="button" onclick="judge_null()">确定</button>
        </tr>
</form>

 

后端代码:

def edit_user():
    if request.method == "GET":
        _id = request.args.get('id')
        user_list = json_util.loads(
            json_util.dumps(MongoHelpMaster('temp_users').database.find_one({'_id': ObjectId(_id)})))
        return render_template('temp_site/peom/backend/edit_user.html', user_list=user_list, session=session["info"])
    elif request.method == "POST":
        username = request.form['username']
        realname = request.form['realname']
        _id = request.args.get('id')
        print(_id)
        result = MongoHelpMaster('temp_users').database.update_one({"_id": ObjectId(_id)}, {
            "$set": {'username': username, 'realname': realname}})

当需要获取前端页面表单传过来的id值的时候,我们就需要用request.args.get,而不能用request.form
