我已经在堆栈溢出和Google上搜索了有关此错误的详细信息，但找不到解决我的情况的解决方案。
我正在使用棉花糖对我的api get请求进行序列化/反序列化。
@post_user_blueprint.route('/api/v1/get_current_profile', methods=['GET'])
@login_required
def get_profile():
query_user_by_order = User.query.join(Sample) \
.join(Individual) \
.join(Ordering) \
.join(Family) \
.join(Sequence) \
.filter(User.id == Sample.fk_user_id) \
.filter(Individual.id == Sample.fk_individual_id) \
.filter(Sample.id == Sequence.fk_sample_id) \
.filter(Individual.id == Ordering.fk_individual_id) \
.filter(Family.id == Individual.fk_family_id) \
.filter(User.email == current_user.email)\ ***********
.all()
result = profile_users_schema.dump(query_user_by_order)
return jsonify({'user': result.data})
@login_required
@post_user_blueprint.route('/profile', methods=['GET', 'POST'])
def profile():
response = requests.get('http://127.0.0.1:5000/api/v1/get_current_profile')
response = response.text
data = json.loads(response) $$$$$$$$$$$$$$$$$
return render_template('profile.html', user_object = data)
*****：当我省略此行时，此方法工作正常，我添加该行的唯一原因是显示登录其个人资料的人，而不显示所有人的个人资料。
$$$$$：这是错误所在。

我不明白为什么会这样，在我将@login_required放在def get_profile上方之后，******行没有直接显示其错误。但是当@login_required不存在时，它会抛出
AttributeError: 'AnonymousUser' object has no attribute 'email'
如果可能的话，我想知道一种获取当前用户电子邮件的方法，这样我就可以查询当前用户的个人资料，而不是整个用户的个人资料。另外，我真的很想知道为什么会出现下面的错误。
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
谢谢，
最佳答案
好的，所以我找到了解决方案，我将全部功劳归功于AArias，因为他建议了一种更干净的方式来获取响应数据。因此，由于HTTP返回的是字节而不是字符串，因此您需要将其显式解码为utf-8，并且许多现有的synthax无法正常工作。.我不知道为什么。
下面的代码有效。
response = get_profile().data
data = json.loads(response.decode('utf-8'))
如果有人尝试使用.read（）或.readall（）对其进行解码，则它将不起作用，因为响应对象没有read或readall方法。最好的方法是最简单的方法，只需对其进行解码并使用'loads'而不是'load'。
希望它能帮助某人
