When notification is passed to the app after payumoney processing it sends response hash and we need to compute the hash and match it with the passed in response hash.
I use the following code to compute the expected response hash.
Digest::SHA512.hexdigest([
PAYU_SALT,
notification.transaction_status,
notification.user_defined,
notification.customer_email,
notification.customer_first_name,
notification.product_info,
notification.gross,
notification.invoice,
PAYU_KEY].join("|"))
The hash of the following string is computed
"salt|success|||||||||||||Payment|100.0|1|key"
When I print the following hash it gives
Digest::SHA512.hexdigest([
PAYU_SALT,
notification.transaction_status,
notification.user_defined,
notification.customer_email,
notification.customer_first_name,
notification.product_info,
notification.gross,
notification.invoice,
PAYU_KEY].join("|"))
#⇒ e7b3c5ba00b98aad9186a5e6eea65028a[...]
whereas notification.checksum gives
#⇒ 546f5d23e0cadad2d4158911ef72f095d[...]
So the two hashes don’t match.
I am using the following gem: https://github.com/payu-india/payuindia
I appreciate any help as to why the response hash is not matching. Is there any error in my logic to compute the response hash? Thanks!
Where did you come up with that order for the fields in the array?
Looking at PayU's Developer FAQ it seems like the order is the following:
key|txnid|amount|productinfo|firstname|email|||||||||||salt
Please make sure that the hash is calculated in the following format - hashSequence= key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||salt
Please make sure that in the above sequence please use the UDFs which have also been posted to our server. In case you haven't posted any UDFs, the hash sequence should look like this - hashSequence= key|txnid|amount|productinfo|firstname|email|||||||||||salt.
Keep in mind that when computing the hash even a single character out of place will result in a completely different checksum.
little late but Actual Sequence is:
SALT|status||||||udf5|udf4|udf3|udf2|udf1|email|firstname|productinfo|amount|txnid|key
Thanks to Ravi Kant Singh
but additionalCharges| are removed
Tested with live environment
Check your hash in above order and if its match you can process request
ok this was a silly mistake i made. The reason the hash didn't match was beacuse i had a typo with the PAYU test key. At the end i typed small 'u' when it was 'U'. The library is fine and the logic is right. The error was in my side with using wrong key.
Actual Sequence for hash is :
additionalCharges|SALT|status||||||udf5|udf4|udf3|udf2|udf1|email|firstname|productinfo|amount|txnid|key
Actual hash generation for additional charges:
additionalCharges|SALT|status||||||udf5|udf4|udf3|udf2|udf1|email|firstname|productinfo|amount|txnid|key
Without additional charges:
SALT|status||||||udf5|udf4|udf3|udf2|udf1|email|firstname|productinfo|amount|txnid|key

My JSON response from an external service looks like this:
Parameters: {"{\"attributes\":{\"type\":\"Lead\",\"url\":\"/services/lead/2231\"},\"Id\":\"2231\",\"FirstName\":\"Jean\"}"=>nil, "external_id"=>"2231"}
How can I parse the Id and FirstName keys in Rails 5? I've tried everything. I know Rails 5 has the .to_unsafe_h method, that's not my problem. It's more the weird nested formatting that has a value of nil after "Jean" above.
If you pay attention closely, you will see:
"{\"attributes\":{\"type\":\"Lead\",\"url\":\"/services/lead/2231\"},\"Id\":\"2231\",\"FirstName\":\"Jean\"}" is actually a string, a key, and the value value associated to it is nil.
If you want to parse that, just can use parameters.keys[0].to_json; although I will double check first why you are getting the parameters in that incorrect state in the first place.
I am trying to pass multiple values for a parameter in a POST request body as follows
var1=1&var2=2&var34=3,4&var5=5
I've tried several ways to pass var34 as a string of values 3 and 4 but still not working. Need some help.
Thanks!!!
This isn't really a question about Fiddler, so it's not clear what you're asking specifically.
The server interprets POST data according to its own rules, and there's no standard for handling duplicate name/values in urlencoded data.
Some servers would accept var1=1&var2=2&var34=3,4&var5=5 as you've used, while some would prefer var1=1&var2=2&var34=3&var34=4&var5=5.
What error or problem are you encountering?
It turns out that it's the server (I use R) side that I need to adjust the codes to accommodate the POST request. It has nothing to do with the request. Thank you so much for the suggestion!
How do I pass array of parameters through Get method in rails? Currently my URL loocs like this:
http://localhost:3000/jobs/1017/editing_job_suites/1017/editing_member_jobs/new?ids[]=1025&ids[]=1027
How can I pass the array with Get method but avoid ?ids[]=1025&ids[]=1027 part.
Request is being sent with javascript window.open method. Is there any workaround to send not ajax Post request.
You should stick to using a GET request if you are not changing the state of anything, and all you want to to access a read only value.
To send an array of ids to rails in a GET request simply name your variable with square brackets at the end.
//angular snippet
$http.(method:'GET',
...
params: {'channel_id':2, 'product_ids[]': productIds}
//where productIds is an array of integers
...
)
Do not concatenate your ids as a comma separated list, just pass them individually redundantly. So in the url it would look something like this:
?channel_id=2&product_ids[]=6900&product_ids[]=6901
url encoded it will actually be more like this:
?channel_id=2&product_ids%5B%5D=6900&product_ids%5B%5D=6901
Rails will separate this back out for you.
Parameters: {"channel_id"=>"2", "product_ids"=>["6900", "6901"]}
No, GET can only put variables on the url itself. If you want the URL to be shorter, you have to POST. That's a limitation feature of HTTP, not Rails.
I recently wanted to do this and found a workaround that is a little less complex, and so has some complexity limitations but may also be easier to implement. Can't speak to security, etc.
If you pass your array values as a string with a delimiter, e.g.
http://example.com/controller?job_ids=2342,2354,25245
Then you can take the result and parse it back to what you want:
job_ids = params[:job_ids].split(',')
Then do whatever:
job_ids.each do |job_id|
job = Job.find(job_id.to_i)
end
etc
#Homan answer is valid for using an external client (e.g curl or angular). Inside Rails test cases though, you should not use []. Here's an example:
get get_test_cases_url(**path_params), params: {case_ids: ["NON-9450", "NON-12345", "NON-9361"]}
This is using new format where get_test_cases is name of route and you pass to the method all params needed to construct the URL path. Query params are a separate hash.
FYI if I use [] like case_ids[], then instead of ["NON-9450", "NON-12345", "NON-9361"] I'm getting it parsed to [["NON-9450"], ["NON-12345"], ["NON-9361"]]
With a request to Twitter for example:
https://api.twitter.com/1/users/show.json?screen_name=stephenfry&include_entities=true
I can extract an element like followers_count using result["followers_count"]
I've tried a similar request to LastFM but their JSON is structured differently as it's a translation of their default XML.
With their demo request:
http://ws.audioscrobbler.com/2.0/?method=artist.getinfo&artist=Cher&api_key=b25b959554ed76058ac220b7b2e0a026&format=json
How would I get the listeners value?
I've tried
result["listeners"]
result["artist.listeners"]
result["artist.stats.listeners"]
I understand I need to access a node, but have no idea how to go about it.
Can anyone help?
It's a nested hash, so you can reach it with:
result["artist"]["stats"]["listeners"]
Example:
require('open-uri')
require('json')
result = JSON.parse(open('http://ws.audioscrobbler.com/2.0/?method=artist.getinfo&artist=Cher&api_key=b25b959554ed76058ac220b7b2e0a026&format=json').read)
result["artist"]["stats"]["listeners"].to_i
The Last.fm data is a series of nested hashes, so you need to access them as such. Give the following a try, it should do the trick:
result["artist"]["listeners"]
I have a simple problem for that I'd like to hear your thoughts:
I have this URL in Rails http://example.com/hosts/show/somehost
I'm getting the 'somehost' part via params[:id]. I'm calling URI.encode on 'somehost' but this does not encode '.' characters. Rails won't recognize ID parts with points in it so I tried to replace the points with '%2E' - That works, but Firefox (and I guess other browsers too) changes the '%2E' back to points right after the request. This makes copy&paste impossible and will lead to a lot of problems.
I'd like to encrypt and decrypt the 'somehost' part in an URL-safe way - Any suggestions? I can't call by an numeric primary key because of the underlying architecture. I have to look up by name.
Thank you all very much!
You could use base64 encoding, but it would be better to fix the actual problem you are having. This issue is described here. You need to set a :requirements key for your routes file with a regex that includes the dot.
