Question

我抓住了pyscopg2+flask+uwsgi的奇怪行为。我试图用apache bench测试一个烧瓶api。对于前2-3个请求，我一直收到此错误：

DatabaseError: SSL error: decryption failed or bad record mac

此后又抛出两个错误：

OperationalError: SSL SYSCALL error: EOF detected

然后请求开始正常工作。我正在使用这个ab命令：

ab -n 100 -c 10 "my_url"

以下是我与pyscopg2建立联系的方式：

from contextlib import contextmanager
from psycopg2.pool import ThreadedConnectionPool

pool = ThreadedConnectionPool(
1, 20,
dbname=pg_name,
user=pg_username,
host=pg_host,
password=pg_password)

@contextmanager
def get_db_connection():
    """
    psycopg2 connection context manager.
    Fetch a connection from the connection pool and release it.
    """
    try:
        connection = pool.getconn()
        yield connection
    finally:
        pool.putconn(connection)


@contextmanager
def get_db_cursor(commit=False):
    """
    psycopg2 connection.cursor context manager.
    Creates a new cursor and closes it, commiting changes if specified.
    """
    with get_db_connection() as connection:
        cursor = connection.cursor()
        try:
            yield cursor
            if commit:
                connection.commit()
        finally:
            cursor.close()

with get_db_cursor() as cur:
    cur.execute("myquery1")
    cur.execute("myquery2")
    cur.execute("myquery3")

最后我为uwsgi运行此命令：

uwsgi --http 0.0.0.0:8081 --wsgi-file my_api.py --master --processes 4 --threads 2 --callable app

谁能告诉我我做错了什么？
