在 werkzeug test_client get 方法的 header 中传递 JWT 令牌

Passing JWT token in the header of werkzeug test_client get method

我目前正在为我的 Flask REST API 编写单元测试。我正在测试的端点需要一个令牌,我成功地从另一个端点获取了该令牌。将此标记传递给 test_client.get() 方法时,出现无法解决的错误。

这是我的单元测试代码:

def test_get_all_users(self):
        # encoding credentials of a user inserted in setup method of test class
        credentials = b64encode(b"user1@mail.com:1234").decode('utf-8')
        # fetch the token using test_client().get()
        # note: self.test_api is my werkzeug test_client() instantiated beforehand
        result = json.loads(self.test_api.get("/users/api/v1/token", headers={"Authorization": f"Basic {credentials}"}).data)
        # encode the token so I can pass it to the get method
        token_encoded = b64encode(bytes(result['token'], 'utf-8')).decode('utf-8')
        # error happens at the next line because of headers?
        result = json.loads(self.test_api.get("/users/api/v1/user", headers={"Authorization": f"JWT {token_encoded}"}).data)
        assert result.status_code == 200
        # ...

被测端点代码:

@api.route("/users/api/v1/user", methods=['GET'])
@token_required
def get_all_users(token):
    """ Function for retrieving all users in db """
    # checking if current user role is valid
    output = []
    # fetching all users
    users = User.query.all()
    # building output dict
    for user in users:
        output.append(dict(user))
    return jsonify({'users' : output})

当我运行测试时,出现以下错误:

        # nominal test
        credentials = b64encode(b"user1@mail.com:1234").decode('utf-8')
        result = json.loads(self.test_api.get("/users/api/v1/token", headers={"Authorization": f"Basic {credentials}"}).data)
        print(result['token'])
        #token_encoded = bytes(result['token'], 'utf-8')
        token_encoded = b64encode(bytes(result['token'], 'utf-8')).decode('utf-8')
        result = json.loads(self.test_api.get("/users/api/v1/user", headers={"Authorization": f"JWT {token_encoded}"}).data)

我很确定错误出在 get 方法的 headers 中,因为 result 似乎是空的。我尝试了几个不同的选项,例如 'x-access-token'、'X-Auth' 等。但是 none 似乎有效,因为我遇到了同样的错误。

你们知道我的代码有什么问题吗?有人可以给我在这个 get() 方法的 headers 中声明令牌的正确方法吗?我上网查了一下,但找不到适合我的东西...

提前致谢!

所以我找到了解决问题的方法。我使用 flask-jwt-extended 模块重写了端点。它使用 Bearer 令牌 headers 所以我的测试现在很容易编写并且全部通过!
