我正在使用请求模块创建一个python应用程序。我最近添加了多处理来加快速度，但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。
代码如下所示：
def hometables_one(conn, request, s, hostname, payload, company):
date1 = request.query.get('date1', '')
date2 = request.query.get('date2', '')
prijmyCelk = 0;

neuhrPrijCelk = 0;
neuhrVydCelk = 0;
dph = 0;
dbNazev = company['dbNazev'];
nazev = company['nazev'];

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

def hometables(request):
s = requests.Session()
response = HTTPResponse()
hostname = request.query.get('hostname', '')[0]
auth = request.query.get('auth', '')[0]
p_queue = []
result = []
json_r = {"success": True}
payload = {'authSessionId': request.query.get('auth', '')[0]}
try:

for company in data:
p_queue.append(Process(target=hometables_one, args=(child_conn, request, s, hostname, payload, company))) #create a new process with hometables_one function
p_queue[-1].start()
for p in p_queue:
received_data = parent_conn.recv()
if "success" not in received_data:
result.append(received_data)s
p.join()
else:
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
在这部分
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)
我收到了当前系统中所有公司的JSON请求，然后我为每个公司运行了hometables_one函数。最终的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"}]
或者像这样：
[{"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，如果只有一个项目hometables_one函数运行没有任何问题，但添加另一个项会导致错误[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。另一件事是当我在没有多处理的情况下运行代码时，即hometable_one函数的内容在hometables函数的for循环中，它运行没有任何问题。
为什么我会收到这些错误？请问有人帮帮我吗？
感谢您的回答
答案 0 :(得分：2)
我遇到过类似的问题。我认为此错误是多个进程尝试访问同一SSL连接的结果。您可以尝试的是在每个进程触发请求之前为其引入随机延迟：
time.sleep(random.randrange(10))
r = s.get("%s/c.json" % hostname, params=payload, verify=False)
