请教 aiohttp clientSession 认证过期带来的重定向问题

使用 aiohttp 的背景:

flask 项目需要访问阿里云上部署的 kubeflow api 服务, 这个 api 参数需要使用 query 传递, 因 query 构造过长报了 413,后考虑拆分 query 并发访问服务.

尝试 1 aiphttp + asyncio

大致代码抽象如下

import asyncio
import json
import re
import functools
from typing import Dict, List

import aiohttp
from loguru import logger


def kubeflow_auth_with_async(func):
    """做 kubeflow 的 auth"""
    @functools.wraps(func)
    async def wrapper(*args, **kwargs):

        async with aiohttp.ClientSession() as session:
            # login
            payload = {
                "username": conf.USERNAME,
                "password": conf.PASSWORD,
            }
            await session.post(conf.AIX_AUTH_URL, data=payload)
            # get req
            # async with session.get(conf.PIPELINE_URL) as response:
            #     text = await response.text()
            response = await session.get(conf.PIPELINE_URL)
            text = await response.text()
            pattern = r"/dex/auth/aix\?req="
            index_beg = re.search(pattern, text).span()
            index_end = text.find('"', index_beg[1])
            req = text[index_beg[1] : index_end]
            params = {"req": req}
            # login kubeflow with aix
            await session.get(conf.DEX_AUTH_URL, params=params)

            return await func(session, *args, **kwargs)

    return wrapper


async def async_get_runs(
    session: aiohttp.ClientSession,
    page_size=1,
    page_token=None,
    experiment_id=None,
    filters=None,
    sort_by="created_at desc",
):

    if not filters:
        filters = {}

    query = {
        "page_size": page_size,
        "page_token": page_token,
        "sort_by": sort_by,
        "resource_reference_key.type": "EXPERIMENT",
        "resource_reference_key.id": experiment_id,
        "filter": json.dumps(filters),
    }
    response = await session.get(
        url=f"{conf.PIPELINE_URL}/apis/v1beta1/runs", params=query
    )  

    # async with session.get(
    #     url=f"{conf.PIPELINE_URL}/apis/v1beta1/runs", params=query
    # ) as response:
    # response.raise_for_status()
    # return await response.json()

    response.raise_for_status()
    return await response.json()


@kubeflow_auth_with_async
async def gather_fetch_runs(
    session: aiohttp.ClientSession,
    runs_lst:List[str],
):
    exp_id = "xxxxx"
    tasks = []
    for sub_runs in runs_lst:
        filters: dict = {
            "predicates": [
                {
                    "key": "id",
                    "op": FILTER_OPERATIONS.IN.value,
                    "string_values": {"values": sub_runs}, 
                },
            ]
        }
        tasks.append(
            async_get_runs(
                session,
                page_size=len(sub_runs),
                experiment_id=exp_id,
                filters=filters,
            )
        )

    return await asyncio.gather(*tasks)


res = []
for r in asyncio.run(gather_fetch_runs(["xxx","xxx","xx"])):
    res.extend(r.get("runs", []))

请教 V 站大佬

出现的报错,不知道怎么贴图,手动概括一下异常

服务稳定运行一段时间后,会出现突然 500 刷新又可以坚挺一段时间
aiohttp.client_exceptions.ContentypTypeError
从报错信息上看像是 session 失效导致的,被 auth 重定向到了登录页. contentType 变成了 text/html
而请求的 url 重定向到了登录的 url,已经不是我传入的那个

因为没试过 async 函数的装饰器,不知道是不是这个问题,
还有就是 clientSession 的连接池是不是保存了 session 的状态. 装饰器每次都重新请求了.这个 session 按道理不应该还是一样的.

尝试 2 gevent + request

也试了,没有这个问题,不过访问次数多起来之后容易莫名 GG,大概率是被自己家部署的 kubeflow 反爬了?
