我使用请求模块创建了一个Python应用程序。我最近添加了多处理以加快速度，但是我开始遇到一些奇怪的错误，例如[Errno 1] _ssl.c:1428: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number或[Errno 1] _ssl.c:1428: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac。代码看起来像这样：

date2 = request.query.get('date2', '')

def hometables(request):

p_queue = []

在此部分
try:
r = s.get("%s/c.json" % hostname, params=payload, verify=False)
r.raise_for_status()
except requests.exceptions.RequestException as err:
response.write(ujson.dumps({ "success": False, "errors": { "reason": str(err)}}))
return response
obj = r.json()
data = obj['companies']['company']
data = make_list(data)
我收到了当前在系统中的所有公司的JSON请求，然后我为每个公司运行hometables_one函数。最终的data看起来像这样：
[{"createDt":"2014-01-28T00:00:00+01:00","dbNazev":"sveatlo","id":"4","licenseGroup":"null","nazev":"Sveatlo","show":"true","stavEnum":"ESTABLISHED","watchingChanges":"false"}]
或喜欢：
[{"createDt":"2014-01-28T00:00:00+01:00","dbNazev":"sveatlo","id":"4","licenseGroup":"null","nazev":"Sveatlo","show":"true","stavEnum":"ESTABLISHED","watchingChanges":"false"},{"createDt":"2014-01-28T00:00:00+01:00","dbNazev":"sveatlo1","id":"4","licenseGroup":"null","nazev":"Sveatlo1","show":"true","stavEnum":"ESTABLISHED","watchingChanges":"false"}]
在第一种情况下，当只有一个项目时， hometables_one函数在没有任何问题的情况下运行，但是添加另一个项目会导致错误 [Errno 1] _ssl.c:1428: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number或 [Errno 1] _ssl.c:1428: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac。另一件事是，当我在不进行多处理的情况下运行代码时，即HOMETABLE_ONE函数的内容在于居家函数中的for循环时，它会毫无问题运行。为什么我会遇到这些错误？有人可以帮我吗？
感谢您的任何答案
我也遇到了类似的问题。我认为此错误是试图访问相同SSL连接的多个过程的结果。您可以尝试的是在每个过程发出请求之前为每个过程引入一个随机延迟：
time.sleep(random.randrange(10))
r = s.get("%s/c.json" % hostname, params=payload, verify=False)
