使用KAFKA主题中的数据并从中提取字段并使用python存储在MySQL中

Question

我想使用以下命令使用来自 Kafka 主题的数据，如下所示：

kafka-console-consumer.sh引导服务器localhost:9092

然后，这将输出以下内容(只粘贴前2行输出，但它将是许多行...):

&time=1561768216000&gameCategory=PINPOINT&category=ONE&uniqueId=2518Z-0892A-0030O-16H70&transactionType=CRD&familyId=000-222-115-11119&realTs=1561768319000&sortId=1&msg=SET-UP+PRAYER+%26+intercession+begins+in+just+30+minutes.&remoteIpAddress=127.0.0.1&userAgent=HTTP&
&uniqueId=872541806296826880&time=1571988786000&gameCategory=NOTIFY&category=TWO&transactionType=CRD&familyId=401-222-115-89387&sortId=1&realTs=1571988989000&msg=This-is+a+reminder.&remoteIpAddress=127.0.0.1&userAgent=HTTPS&

我想使用输出中的以下内容:

>

房地产经纪人

家庭标识

消息

唯一标识

您可以看到，每个元素都用一个&符号（'

描述测试表；

到目前为止，我有什么？我有一个带有 python 的 mysql 连接器，我可以在其中连接到本地 mysql 等，但我正在努力解析并插入它......

Answer 1

使用Python，您可以使用urllib.parse.parse_qs检索Python字典中的URL查询字符串组件，您可以稍后迭代这些组件以将数据插入MySQL数据库。

例如:

from urllib.parse import parse_qs
line = "&time=1561768216000&gameCategory=PINPOINT&category=ONE&uniqueId=2518Z-0892A-0030O-16H70&transactionType=CRD&familyId=000-222-115-11119&realTs=1561768319000&sortId=1&msg=SET-UP+PRAYER+%26+intercession+begins+in+just+30+minutes.&remoteIpAddress=127.0.0.1&userAgent=HTTP&uniqueId=872541806296826880&time=1571988786000&gameCategory=NOTIFY&category=TWO&transactionType=CRD&familyId=401-222-115-89387&sortId=1&realTs=1571988989000&msg=This-is+a+reminder.&remoteIpAddress=127.0.0.1&userAgent=HTTPS&"

o = parse_qs(line)

print(o)

结果：

{'time': ['1561768216000', '1571988786000'], 'gameCategory': ['PINPOINT', 'NOTIFY'], 'category': ['ONE', 'TWO'], 'uniqueId': ['2518Z-0892A-0030O-16H70', '872541806296826880'], 'transactionType': ['CRD', 'CRD'], 'familyId': ['000-222-115-11119', '401-222-115-89387'], 'realTs': ['1561768319000', '1571988989000'], 'sortId': ['1', '1'], 'msg': ['SET-UP PRAYER & intercession begins in just 30 minutes.', 'This-is a reminder.'], 'remoteIpAddress': ['127.0.0.1', '127.0.0.1'], 'userAgent': ['HTTP', 'HTTPS']}
