从同一服务器调用Django rest framework终结点时出错

Question

我有一个API端点，比如说sampleapi.domain.com/api/v1/1，它在本地(127.0.0.1)和在线sampleapi-dev.domain.com的开发中工作得很好，但是当我从进行调用的服务器sampleapi.domain.com调用同一个端点sampleapi.domain.com/api/v1/1时，我得到了

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

这是不寻常的，因为相同的代码在开发和在线工作。返回的HTTP代码是500而不是200（对于本地测试和开发服务器中的相同API调用返回的代码）

当我改变开始的方式时gunicorn

从gunicorn --certfile=crt --keyfile=key --bind 0.0.0.0:8000 a.wsgi

到gunicorn --certfile=crt --keyfile=key --bind 0.0.0.0:8000 a.wsgi -w 1 --threads 2

这似乎解决了错误，但我不完全确定为什么会这样

是因为单个线程忙于加载API所在的页面，所以无法调用API吗？ 如果这不是原因，原因可能是什么

get_api

def get_api():
    url = 'https://sampleapi.domain.com/api/v1/1'
    params = {'Authorization': 'Token ' + os.environ.get("token")}
    try:
        response = requests.get(url, headers=params)
    except requests.exceptions.RequestException:
        return "Could not grab api text."

    return response.json()

试着使用它

gunicorn Config.wsgi:application  bind 0.0.0.0:8000 -w 3
