DEVOPS : Slack : How to Upload File to Slack using Python

DEVOPS : Slack : How to Upload File to Slack using Python

Slack Vineet Sachdeva   February 14, 2020

When uploading files to slack using Webhook - it is not possible. You need to use Slack API.
Below is sample code which can be used to put files to slack.

The key thing here is the token. You need to request a new token from Slack which you can do from Below URL - 

https://api.slack.com/legacy/custom-integrations/legacy-tokens

Sample Code - 

import requests
token  = "xxxxxxx"my_file = {
  'file' : ('/tmp/temp_file.out', open('/tmp/temp_file.out', 'rb'), 'txt')
}
payload={
  "filename":"temp_file.out",
  "token":token,
  "channels":['#channel-name'],
}
r = requests.post("https://slack.com/api/files.upload", params=payload, files=my_file)

Amazon Web Services (AWS): Boto3 SQS Operations

Amazon Web Services (AWS): Boto3 SQS Operations

Boto3 Vineet Sachdeva   February 08, 2020

In this blog I am going to cover on how to run multiple SQS Operations using Boto3. 
Note - all the response from which are printed will give HTTP Status Code 200 which signifies that the operation which you had performed had completed successfully.
Create Queue

import boto3

QName = "MyNewFIfoQueue.fifo"Attr = {'FifoQueue': 'true'}
sqs = boto3.resource('sqs')
response = sqs.create_queue (QueueName = QName, Attributes = Attr)
print (response)import boto3

QName = "MyNewFIfoQueue.fifo"Attr = {'FifoQueue': 'true'}
sqs = boto3.resource('sqs')
response = sqs.create_queue (QueueName = QName, Attributes = Attr)
print (response)

And the response 

sqs.Queue(url='https://queue.amazonaws.com/<accid>/MyNewFIfoQueue.fifo')

You can verify the same from Console or AWS CLI

$ aws sqs list-queues
{
    "QueueUrls": [
        "https://queue.amazonaws.com/<accid>/MyNewFIfoQueue.fifo"    ]
}

Send Messages to Queue

import boto3
import uuid

QName = "MyNewFIfoQueue.fifo"
sqs = boto3.client('sqs')
QUEUE_URL = sqs.get_queue_url(QueueName = QName)['QueueUrl']
response = sqs.send_message(
                           QueueUrl=QUEUE_URL,
                           MessageBody="TestMessage",
                           MessageGroupId="TestGroup",
                           MessageDeduplicationId=str(uuid.uuid4()))
print(response)


And the response
{u'MD5OfMessageBody': '08ff08d3b2981eb6c611a385ffa4f865', 'ResponseMetadata': {'RetryAttempts': 0, 'HTTPStatusCode': 200, 'RequestId': 'b18d5e81-a666-541b-aaa4-0839850e0a6e', 'HTTPHeaders': {'x-amzn-requestid': 'b18d5e81-a666-541b-aaa4-0839850e0a6e', 'date': 'Sat, 08 Feb 2020 02:47:04 GMT', 'content-length': '431', 'content-type': 'text/xml'}}, u'SequenceNumber': '18851513359964655616', u'MessageId': '3a9b64ad-4eb3-4606-9eec-c9c5369d4304'}






Receive messages From Queue




import boto3
QName = "MyNewFIfoQueue.fifo"
sqs = boto3.client('sqs')
QUEUE_URL = sqs.get_queue_url(QueueName = QName)['QueueUrl']
response = sqs.receive_message(
                           QueueUrl=QUEUE_URL,
                           MaxNumberOfMessages=1                           )['Messages'][0]
print(response)


And the response 
{u'Body': 'TestMessage', u'ReceiptHandle': 'AQEBmnx4wSlS0Qf/kramgeBUr8lMEHrWkILeK3SIoxMjfnMjRGrXtm8w8BUXiiKJQSaFYaGYnJF6kpFrYeFPoGlrVcJgn6Ci3WpM+pVm1Ih0XT4SkHQBjH2CIxKfx21t+oyej7mYi3PwNENOHJI125BNuAVnfSAys64uBFPXgEPgRy/OFBVK2CcueJy18I8sPm6dNV5CCzxfzZE3csd/TBOQsnhtAPt3sro3MfZUUUc5d3iIrhGjVa/xNXiNNHECMu5ZifCTU8U1pX2lX1EwV3CYzrlnr2mie/R6SkJqEvPjsfc=', u'MD5OfBody': '08ff08d3b2981eb6c611a385ffa4f865', u'MessageId': '3a9b64ad-4eb3-4606-9eec-c9c5369d4304'}






Purge and Delete Queue

import boto3

QName = "MyNewFIfoQueue.fifo"
sqs = boto3.client('sqs')
QUEUE_URL = sqs.get_queue_url(QueueName = QName)['QueueUrl']
response = sqs.purge_queue(QueueUrl=QUEUE_URL)
print(response)
response = sqs.delete_queue(QueueUrl=QUEUE_URL)
print(response)

And the response

{'ResponseMetadata': {'RetryAttempts': 0, 'HTTPStatusCode': 200, 'RequestId': '364d9e6a-9b1b-555e-b5af-c8d2bd4abe6a', 'HTTPHeaders': {'x-amzn-requestid': '364d9e6a-9b1b-555e-b5af-c8d2bd4abe6a', 'date': 'Sat, 08 Feb 2020 02:59:29 GMT', 'content-length': '209', 'content-type': 'text/xml'}}}
{'ResponseMetadata': {'RetryAttempts': 0, 'HTTPStatusCode': 200, 'RequestId': '75808c73-aac5-5dec-b3a4-dacb8c9446d8', 'HTTPHeaders': {'x-amzn-requestid': '75808c73-aac5-5dec-b3a4-dacb8c9446d8', 'date': 'Sat, 08 Feb 2020 02:59:29 GMT', 'content-length': '211', 'content-type': 'text/xml'}}}

Amazon Web Services (AWS): Installing and Configuring AWSCLI

Amazon Web Services (AWS): Installing and Configuring AWSCLI

AWSCLI Vineet Sachdeva   February 07, 2020

In this short blog, I am going to cover on quickly how to configure awscli.

Step 1 : Install awscli
pip3.7 install awscli --upgrade --user
(if you have different verison of pip like pip3, pip2.7) you can use that as well


Step 2: Configure API Access
The first thing is that you should know your API keys, to do that you can use the URL. 

Step 3: Conifgure CLI
Add awscli to your Path.
For MAC it is generally : 
export PATH=$PATH:/Users/<username>/Library/Python/3.7/bin

Then do configure , keep your key and secret access key handy.

aws configure 

AWS Access Key ID []: ****************rMFO

AWS Secret Access Key [****************rE0P]: f****************rUWbzxpt

Default region name []: us-east-1

Default output format []: json

Look at the files ~/.aws/credentials and configure.

You will find what you had entered configured in these files.

So, yo u can change anytime you want from these files as well.
