python - Flask报错ValueError：无效的键'昵称”

Question

提出一个问题，也顺便记录一下~，因为涉及到的文件比较多，所以只贴部分代码：
下面是views文件：

from flask import render_template, flash, redirect, session, url_for, request, g
from flask_login import login_user, logout_user, current_user, login_required
from app import app, db, lm, oid

from .models import User


@lm.user_loader
def load_user(id):
    return User.query.get(int(id))


@app.before_request
def before_request():
    g.user = current_user


@app.route('/')
@app.route('/index')
@login_required
def index():
    user = {'nickname': 'anryan'}
    posts = [
        {
            'author': {'nickname': 'Anryan'},
            'body': u'这地方不错~'
        },

            'body': u'玩王者荣耀也不错。'
        }
    ]
    return render_template('index.html',
                           title='Home',
                           user=user,

    return render_template('login.html',
                           title=u'点击进入',
                           form=form,
                           providers=app.config['OPENID_PROVIDERS'])

        user = User(nicknickname=nicknickname, email=resp.email)
        db.session.add(user)
        db.session.commit()
    remember_me = False
    if 'remember_me' in session:
        remember_me = session['remember_me']
        session.pop('remember_me', None)
    login_user(user, remember=remember_me)
    return redirect(request.args.get('next') or url_for('index'))


@app.route('/logout')

    logout_user()

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:
