I am asking about the scenario of a RESTful service in a particular case. Assume that this is a file delevery service. Users submit an order then after a period of time ( 1-10 min ) a pdf file is ready for them to download. So the basics I came with:
user submits an order using GET method to the webservice ( edit: OR POST )
webservice returns an orderid via json or xml
some background and human process takes place ( 1 - 10 mins )
user checks the status of the order by passing the orderid to the webservice
if the order is ready then an statusCode and a pdfLink is returned to user
else only the statusCode is returned (i.e still proccessing, failed, etc)
Now, the question about this scenario is that how often the user ( other website ) should try to fetch the status of one specific order?
Do we need to stablish a double side webservices ? like:
server A submits the order to B
B informes A that the order is ready to get
A requests B for the pdfLink
A transferes the pdf file from server B to A
When server A submits an order to B, it could also specify an url on which it expects a call if the order is ready. This way service B does not need to know the specifics of service A. It just calls the url specified by service A.
The response service B gives to service A, could also contain a url where to download the order.
This prevents polling from server A to server B, which significantly reduces the load on service B.

I am using Google API Client for fitness to retrieve user fitness data using the PHP Client library.
My usecase: To get users Total run time for the day, and also distance.
I am using the following code (sample code with key steps):
$service = new Google_Service_Fitness($google_client);
$dataSets = $service->users_dataset;
..
$aggBy->setDataTypeName("com.google.activity.segment");
..
$aggregates = $dataSets->aggregate('me',$aggReq);
I am using com.google.activity.segment as datatypename:
I get a response with run type with data
Activity type: 8
runtime : value in msec
no of segment: 2
Now i want to get the total distance travelled during running session,
From above response i can make out that user had 2 separate running activity, then how i can get the combined distance done by the particular activity?
Also how i can retrieve details about these in 2 running segment in details?
As said i am using PHP Client API.
I am new to Jmeter and doing a POC to do a load test on a web application.
What I am trying to do:
I have a total of 4 user logins(surgeons). Each Login is associated with 'n' number of patients.
I've created 2 CSV files
1. one with the user login and password for surgeons
2. another CSV file that contains the PatientName, PatientID and the Surgeon associated with that Patient like below.
PatientName,PatientId,loginName
Pa1,PID1,user1
Pa2,PID2,user1
Pa3,PID3,user1
Pa4,PID4,user1
Pa5,PID5,user2
Pa6,PID6,user2
Pa7,PID7,user3
Pa8,PID8,user4
My Scenario:
Login as User.
Navigate to Each Patient Dashboard as per their associations.
log out of the application.
My Testplan
Thread Group (4 users, Ramp up time as 1 sec, 1 loop)
-csv1(with username, password )
-Login Page and Navigate to the Main page
- RunTime Controller (To sustain the load of a set amount of time)
-- While Loop(to loop between the patient dashboard of the surgeon/user logged in)
---CSV2 (the data as shown above)
----Navigate to Dashboard
----Navigate to Main
-Log out of the Application
What I want to achieve:
I want to use the single thread group and run it concurrently for all the 4 users. In this process, once the user login, the user should only those patient data from the CSV which are associated.
For Ex:
When the Thread1 is running with User1 login, he should only able to loop through Pa1, Pa2, Pa3, Pa4 users
When the thread2 is running with User2 login, user should only read the Pa5, Pa6 data.
Like this, each user login should only pick those users as per their associations mentioned above.
Is there any way, I can use this single CSV2 file and achieve this task? so that I don't have to create n number of the thread of n numbers of logins with n number CSV files each containing the data specific to the user login.
According to JMeter Test Elements Execution Order
0. Configuration elements
Pre-Processors
Timers
Sampler
Post-Processors (unless SampleResult is null)
Assertions (unless SampleResult is null)
Listeners (unless SampleResult is null)
Being a Configuration Element CSV Data Set Config is initialized once and before anything else therefore you won't be able to use the current variable from 1st CSV Data Set Config in 2nd CSV Data Set Config.
The solution is using __CSVRead() function instead, JMeter Functions are evaluated in the place where they appear in the Test Plan so you can use any hardcoded value or JMeter Variable or another function there.
More information: How to Pick Different CSV Files at JMeter Runtime
1. CSV Data Set Config for Surgeon credentials (loginNameSurgeon & Password)
2. Login Request (take first surgeon credentials from CSV)
3. While ${__jexl3("${loginNameSurgeon}" != "${loginName}")}
a. CSV Data Set Config for patient data w.r.t surgeons (PatientName,PatientId,loginName)
b. If Controller - ${__jexl3("${loginName}" != "<EOF>")} // to check if we have any more loginName left
c. Dashboard request
d. Debug Sampler // Just to validate if the variables are in place.
4. Logout request
I send to my telegram bot a few photos as group. How I can get the file_id all of my uploaded photos?
I use webhooks, but response is not contain any data about all photos, just some data about last uploaded photo and media_group_id. How I can get all file_id's of my uploaded group photos
response:
The Telegram Bot API does not give to your web-hook any reliable information about the order of each item in a media group. https://core.telegram.org/bots/api#message
Suggestions:
If bot is in a private chat, save the incoming file_id against their media_group_id. Whenever media_group_id changes you would have all you need to use. Engage the user in some other way so that you can quickly determine the media_group_id change and respond quickly from that processing.
If bot is in a group chat, save incoming file_id against the users id as well as media_group_id and similarly monitor changes to media_group_id and user id to take action.
When a solution starts getting too complex for my liking, I prefer to go back to the basic reason for my need and perhaps find out that I do not need to do something an API doesn't afford like "Get all uploaded photos by media_group_id". Maybe I can just process them individually as the updates stream in.
Tip: If the media group has a caption and you only care about the first media item in the group, then monitoring the media_group_id and caption of an incoming message should be sufficient.
if(message.caption != null && message.media_group_id != null){
// first item in new group received
}
Okay, this way is not simple and not elegant but it's working.
We need to see in webhook response media_group_id element - this means that this is a group of media.
If the first point is true - save the data about this media on own server (data must be contain media_group_id)
example: ["media_group_id" => [[some data about photo]]]
When next webhook is come, we need to see his media_group_id, if it's the same - ok, add him to array...
example: ["media_group_id" => [[some data about photo],[some data about photo]]]
if not - ok, make a new element of array:
example: ["media_group_id" => [[some data about photo]], "media_group_id2" =>
[[some data about photo]]]
So we got an array that contains all data about the photos of the one(or more) group.
hmmm... I don't like this way, but how make better?
In Pyrogram, we can use the get_media_group function, https://docs.pyrogram.org/api/methods/get_media_group.html#pyrogram.Client.get_media_group. in my opinion, it is much better than using BOT API.
The SQL engine hides away all nifty details on what API calls are being done. However, some cloud solutions have pricing per API call.
For instance:
select *
from transactionlines
retrieves all Exact Online transaction lines of the current company, but:
select *
from transactionlines
where financialyear = 2016
filters it effectively on REST API of Exact Online to just that year, reducing data volume. And:
select *
from gltransactionlines
where year_attr = 2016
retrieves all data since the where-clause is not forwarded to this XML API of Exact.
Of course I can attach fiddler or wireshark and try to analyze the data volume, but is there an easier way to analyze the data volume of API calls with Invantive SQL?
First of all, all calls handled by Invantive SQL are logged in the Invantive Cloud together with:
the time
data volume in both directions
duration
to enable consistent API use monitoring across all supported cloud platforms. The actual data is not logged and travels directly.
You can query the same numbers from within your session, for instance:
select * from exactonlinerest..projects where code like 'A%'
retrieves all projects with a code starting with 'A'. And then:
select * from sessionios#datadictionary
shows you the API calls made:
You can also put a query like to following at the end of your session before logging off:
select main_url
, sum(bytes_received) bytes_received
, sum(duration_ms) duration_ms
from ( select regexp_replace(url, '\?.*', '') main_url
, bytes_received
, duration_ms
from sessionios#datadictionary
)
group
by main_url

Tinkering around with verifying a couple of domains and found the manual process rather tedius. My DNS controller offers API access so I figured why not script the whole thing.
Trick is I can't figure out how to access the required TXT & CNAME records for DKIMS verification from boto, when I punch in
dkims = conn.verify_domain_dkim('DOMAIN.COM')
it adds DOMAIN.COM to the list of domains pending verification but doesn't provide the needed records, the returned value of dkims is
{'VerifyDomainDkimResponse': {
'ResponseMetadata': {'RequestId': 'REQUEST_ID_STRING'},
'VerifyDomainDkimResult': {'DkimTokens': {
'member': 'DKIMS_TOKEN_STRING'}}}}
Is there some undocumented way to take the REQUEST_ID or TOKEN_STRING to pull up these records?
UPDATE
If you have an aws account you can see the records I'm after at
https://console.aws.amazon.com/ses/home?region=us-west-2#verified-senders:domain
tab: Details:: Record Type: TXT (Text)
tab: DKIM:: DNS Record 1, 2, 3
these are the records required to add to the DNS controller to validate & allow DKIM signatures to take place
This is how I do it with python.
DOMINIO = 'mydomain.com'
from boto3 import Session
session = Session(
aws_access_key_id=MY_AWS_ACCESS_KEY_ID,
aws_secret_access_key=MY_AWS_SECRET_ACCESS_KEY,
region_name=MY_AWS_REGION_NAME)
client = session.client('ses')
# gets VerificationToken for the domain, that will be used to add a TXT record to the DNS
result = client.verify_domain_identity(Domain=DOMINIO)
txt = result.get('VerificationToken')
# gets DKIM tokens that will be used to add 3 CNAME records
result = client.verify_domain_dkim(Domain=DOMINIO)
dkim_tokens = result.get('DkimTokens') # this is a list
At the end of the code, you will have "txt" and "dkim_tokens" variables, a string and a list respectively.
You will need to add a TXT record to your dns, where the host name is "_amazonses" and the value is the value of "txt" variable.
Also you will need to add 3 CNAME records to your dns, one for each token present in "dkim_tokens" list, where the host name of each record is of the form of [dkimtoken]._domainkey and the target is [dkimtoken].dkim.amazonses.com
After adding the dns records, after some minutes (maybe a couple of hours), Amazon will detect and verify the domain, and will send you an email notification. After that, you can enable Dkim signature by doing this call:
client.set_identity_dkim_enabled(Identity=DOMINIO, DkimEnabled=True)
The methods used here are verify_domain_identity, verify_domain_dkim and set_identity_dkim_enabled.
You may also want to take a look a get_identity_verification_attributes and get_identity_dkim_attributes.
I think the get_identity_dkim_attributes method will return the information you are looking for. You pass in the domain name(s) you are interested in and it returns the status for that identity as well as the DKIM tokens.
