每次我尝试使用邮递员测试我的注册 Api 时，我都会收到内部服务器错误作为返回的错误消息，而在我的终端上我会收到此错误
[2020-01-05 07:14:52,933] ERROR in app: Exception on /register [POST]

以下是我的注册和用户检查代码
class Register(Resource):
def post(self):
postedData = request.get_json()
username = postedData["username"]
password = postedData["password"]
if UserExist(username):
retJson = {
"status code": 301,
"message": "Invalid username"
}
return jsonify(retJson)
hashed_pw = bcrypt.hashpw(password.encode('utf8'), bcrypt.gensalt())
users.inser({
"Username": username,
"Password": hashed_pw
})
retJson = {
"status code": 200,
"message": "successfully registered"
}
return jsonify(retJson)
def UserExist(username):
count = db.users.count_documents({"Username": username})
if count <= 0:
return False
else:
return True
我已经尝试了我能想到的每一个技巧，请知道出了什么问题以及如何解决这个问题，谢谢。
【问题讨论】：
-
我们需要了解您是如何创建 db 变量以及您传递给 MongoClient 的参数
-
检查mongodb服务器是否正在运行？？
-
@vikas 是的，我的 mongodb 服务器正在运行
-
@Belly 这里是我创建数据库的方式 client = MongoClient("mongodb://:27017") db = client.SimDB users = db["Users"] # for admin admin = db[ “管理员”]
-
你有没有通过 api.add 为此创建路由？？
