[英]Consume data from KAFKA topic and extract fields from it and store in MySQL using python
I want to consume data from a Kafka topic with the following command as follows:我想使用以下命令使用来自 Kafka 主题的数据,如下所示:
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic myTestTopic --from-beginning bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic myTestTopic --from-beginning
Then this will output the following (just pasting top 2 lines output, but it will be many lines...):然后这将输出以下内容(仅粘贴前 2 行输出,但它将是多行...):
&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&
I want to consume the following from the output:我想从输出中使用以下内容:
realTs房地产
familyId家庭 ID
msg留言
uniqueId唯一身份
and you can see that each element is seperated by an ampersand ('&').并且您可以看到每个元素都由与号 ('&') 分隔。 They are not always in same index/place so I'm not sure if I need a regex?它们并不总是在相同的索引/位置,所以我不确定是否需要正则表达式? Eventually when I do the query on a local running MySQL, i'd see this:最终,当我在本地运行的 MySQL 上进行查询时,我会看到:
describe testTable;描述测试表;
+----------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------+--------------+------+-----+---------+-------+
| realTs | bigint(20) | YES | | NULL | |
| familyId | varchar(255) | YES | | NULL | |
| msg | text | YES | | NULL | |
| uniqueId | varchar(255) | YES | | NULL | |
+----------+--------------+------+-----+---------+-------+
4 rows in set (0.00 sec)
SELECT * FROM testTable; SELECT * FROM testTable;
+---------------+-------------------+-----------------------------------------------------------+-------------------------+
| realTs | familyId | msg | uniqueId |
+---------------+-------------------+-----------------------------------------------------------+-------------------------+
| 1561768319000 | 000-222-115-11119 | SET-UP+PRAYER+%26+intercession+begins+in+just+30+minutes. | 2518Z-0892A-0030O-16H70 |
| 1571988989000 | 401-222-115-89387 | This-is+a+reminder. | 872541806296826880 |
+---------------+-------------------+-----------------------------------------------------------+-------------------------+
What do I have so far?到目前为止我有什么? I have a mysql-connector with python where I can connect to a local mysql etc, but i'm struggling with parsing this and inserting it...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,但是我正在努力解析它并插入它......
With Python, you can use urllib.parse.parse_qs
to retrieve URL query string components in a Python dictionary that you can iterate later to insert data in your MySQL database.使用 Python,您可以使用urllib.parse.parse_qs
在 Python 字典中检索 URL 查询字符串组件,您可以稍后迭代以在 MySQL 数据库中插入数据。
For instance: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)
Result: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']}
