几个 http 请求是在一个循环中发出的。换句话说，这个函数被多次调用:

import requests
def execute_request(ad_entity, data, url=None):
    data_bytes = json.dumps(data, ensure_ascii=False).encode("utf-8")

    headers = get_headers()

    URL = url or '{}{}/'.format(API_ADDRESS, ad_entity.value.lower())

    response = requests.post(URL, headers=headers, data=data_bytes,
                             verify=False)

这个问题似乎与python本身的线程安全有关。它似乎与 Django 无关。我试图通过在请求之间添加最多 2 秒的 sleep 来解决它。尽我所能，这并没有帮助。

你能在这里踢我吗:
1. 这段代码是什么意思，在哪里可以读到它？
2. 这个问题有什么解决办法吗？
3. 我可以打开更详细的日志记录或在某处找到更深入的日志吗？
4. 无论如何，如何定位这个问题？

Answer 1

这些警告来自 urllib3由于禁用了 HTTPS 证书验证而导致的模块。
对此负责的部分是 verify=False要修复它，只需将其删除或替换为 verify=True (默认)
另一种抑制警告的方法(强烈不推荐)是在导入请求之前添加以下内容:

import urllib3
urllib3.disable_warnings()
