Question

我正在尝试向以下代码添加令牌机制。我尝试了很多方法，但下面一种似乎是实现 jwt 的更简单方法。但是当我运行代码时，在 from security import authenticate, identity

处出现模块错误

我也尝试通过创建单独的 requirements.txt 但它不起作用。

这是我的代码

from flask import request
from flask import Flask
#from jsonify.convert import jsonify
from flask import jsonify
from pyspark.shell import spark
from pyspark.sql import SparkSession
from pyspark.sql.types import StructType, StructField, StringType, IntegerType

#from flask_jwt_extended import create_access_token

import base64
from flask_jwt_extended import jwt_required
from flask import Flask
from flask_jwt import JWT
from security import authenticate, identity

app = Flask(__name__)
app.secret_key = "righdata"  # Make this long, random, and secret in a real app!
jwt = JWT(app, authenticate, identity)
app.config['JWT_ALGORITHM'] = 'HS512'
#jwt = JWTManager(app)
spark = SparkSession.builder.master("local").appName("DX_STATS").enableHiveSupport().getOrCreate()
spark.sql("SHOW TABLES").show()

class User(object):
    def __init__(self):
        self.id = id
        self.username = "abc"
        self.password = "password"

    def __str__(self):
        return "User(id='%s')" % self.id

users = [
    User(1, 'abc', 'password'),
]

username_table = {u.self.username: u for u in users}
userid_table = {u.id: u for u in users}

def authenticate():
    username = "abc"
    password = "password"
    user = username_table.get(username, None)
    if user and safe_str_cmp(user.password.encode('utf-8'), password.encode('utf-8')):
        return user

def identity(payload):
    user_id = payload['identity']
    return userid_table.get(user_id, None)

app = Flask(__name__)
app.debug = True
app.config['SECRET_KEY'] = 'secret_key'

jwt = JWT(app, authenticate, identity)

# if __name__ == '__main__':
#     app.run()
@app.route('/analyze', methods=["POST"])
@jwt_required()
def analyze():
    print(request.is_json)
    content = request.get_json()
    print(content)
    dir = content["preview"]
    print(dir)
    sql = "select * from " + tablename + " limit " + str(content["previewCount"])
    df = spark.sql(sql)
    data = df.toPandas()
    stats = data.describe(include=['object'])
    df2 = data.isnull().sum()
    notnull = data.notnull().sum()
    zero = (data == 0).sum(axis=0)
    nonzero = (data != 0).sum(axis=0)
    null_result = json.loads(df2.to_json(orient="index"))
    not_null = json.loads(notnull.to_json(orient="index"))
    stats_result = json.loads(stats.to_json(orient='index'))
    zero_result = json.loads(zero.to_json(orient="index"))
    non_zero = json.loads(nonzero.to_json(orient='index'))
    
    return json.dumps(stats_result, indent=4)

if __name__ == '__main__':
    app.run(debug=True)  # host = "0.0.0.0",port = specific port0

我收到此错误：

Traceback (most recent call last):
  File "new.py", line 19, in <module>
    from .security import authenticate, identity
ModuleNotFoundError: No module named '__main__.security'; '__main__' is not a package
^C
[1]+  Exit 1                  python new.py
$ python3 -m security
/bin/python3: No module named security
$~/myproject$

实际错误：回溯（最近一次调用最后一次）：文件“new.py”，第 19 行，在从安全进口认证，身份 ModuleNotFoundError: 没有名为“安全”的模块

而且我也遇到了以下错误：

错误 1：

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
flask-jwt 0.3.2 requires PyJWT<1.5.0,>=1.4.0, but you have pyjwt 2.1.0 which is incompatible.
flask-appbuilder 3.3.0 requires Flask-JWT-Extended<4,>=3.18, but you have flask-jwt-extended 4.2.1 which is incompatible.
flask-appbuilder 3.3.0 requires PyJWT<2.0.0,>=1.7.1, but you have pyjwt 2.1.0 which is incompatible.

错误 2：

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
flask-jwt 0.3.2 requires PyJWT<1.5.0,>=1.4.0, but you have pyjwt 1.7.1 which is incompatible.

这些总是安装最新版本。如何安装特定版本。

我正在尝试将 jwt 合并到我的代码中，但出现模块错误
