我使用flask-peewee制作一个API,如果用户不存在于表中,我想返回一个404 json但看起来好像是在抛出500错误而不是404错误json：
这是我得到的错误：
UserDoesNotExist: instance matching query does not exist:
sql: SELECT t1.`id`,t1.`username`,t1.`password`,t1.`email`,t1.`token`,t1.`join_date`,t1.`active`,t1.`admin` FROM `user` AS t1 WHERE ((t1.`active` = %s) AND (t1.`username` = %s))
[Wed Sep 18 20:26:24 2013] [error] [client 173.225.41.154] PARAMS: [True,u'fery3']
码：
@app.route('/api/login/',methods=['POST'])
def authenticate1():
if request.method == 'POST' and request.form['username']:
active = User.select().where(User.active==True)
user2 = User.select().where(User.username==request.form['username']).get()
try:
user = active.where(User.username==request.form['username']).get()
except exceptions: # includes simplejson.decoder.JSONDecodeError
return make_response(jsonify( { 'error': 'Bad request' } ),400)
else:
if not user.check_password(request.form['password']):
return make_response(jsonify( { 'error': 'Bad request','message': 'Wrong Username or Password'} ),400)
return make_response(jsonify( { "Meta":{'model':'login','code':'200','status':'ok','message':'successfully loggedin'},'objects':[{'username': user2.username,'email':user2.email,'token' : user2.token }] } ),200)
最佳答案
active = User.select().where(User.active == True)
try:
user = active.where(User.username == request.form['username']).get()
except User.DoesNotExist:
return make_response(jsonify({'error': 'Bad request'}),400)
else:
if not user.check_password(...)
