Python 将芹菜工人与烧瓶一起使用时出现协议错误

我在用烧瓶管理远程芹菜工人。flask中的配置是redis用于后端，rabbitmq用作消息代理

Flask使用多个线程运行，芹菜get（）用于两个位置

@app.routes("/route1")
def method1():
    result1_obj = remote_method_1.apply_async()
    result1 = result1_obj.get()

@app.routes("/route2")
def method2():
    result2_obj = remote_method_2.apply_async()
    result2 = result2_obj.get()

因此，每当method1（）和method2（）下的两个不同线程同时调用get（）时

错误日志如下所示：-

有没有关于如何解决此错误的建议？

这是芹菜库中的一个错误

现在后端对象不是线程安全的

您需要在没有线程的情况下运行Flask应用程序，例如，

uwsgi--processs 12--threads 1--http 0.0.0.0:5000--module server:app

显示的是完整的错误回溯@美元。我已经添加了错误日志。您是否在线程之间共享一个redis连接？@klauds。是的，我使用一个redis连接作为后端，我应该使用多个redis连接吗？
