Python請求ssl [Errno 1] _ssl.c：1428：錯誤：1408F10B：SSL例程：SSL3_GET_RECORD：版本號錯誤

Question

我正在使用請求模塊創建一個python應用程序。 我最近添加了多處理以加快它的速度，但我開始得到一些奇怪的錯誤，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 。 代碼如下所示：

def hometables_one(conn, request, s, hostname, payload, company):

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

    nazev = company['nazev'];

    if date1 and date2:

            r = s.get("%s/c/%s/faktura-vydana/(duzpPuv between %s %s)/$sum.json" % (hostname, dbNazev, date1[0], date2[0]), params=payload, verify=False)
            r.raise_for_status()

        p_queue[-1].start()

    for p in p_queue:

            response.write(ujson.dumps(received_data)) #error in hometables_one function
            return response

    json_r["data"] = result
    response.write(ujson.dumps(json_r))
    return response

在這一部分

    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)

我收到了當前處於系統中的所有公司的JSON請求，然后我為每個公司運行了hometables_one函數。 最終data可能如下所示：

[{"createDt":"2014-01-28T00:00:00+01:00","dbNazev":"sveatlo","id":"4","licenseGroup":"null","nazev":"Sveatlo","show":"true","stavEnum":"ESTABLISHED","watchingChanges":"false"}]

或者像這樣：

[{"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"}]

在第一種情況下，當只有一個項目時， hometables_one函數運行沒有任何問題，但添加另一項導致錯誤[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，當我在沒有多處理的情況下運行代碼時，即hometable_one函數的內容在hometables函數的for循環中，它運行沒有任何問題。 為什么我會收到這些錯誤？ 請問有人幫幫我嗎？

謝謝你的回答

我遇到過類似的問題。 我認為此錯誤是多個進程嘗試訪問同一SSL連接的結果。 您可以嘗試的是在每個進程觸發請求之前引入隨機延遲：

time.sleep(random.randrange(10))
r = s.get("%s/c.json" % hostname, params=payload, verify=False)
