I have successfully send ARQC to host, In response I have field 55 (ISO 8583) with different tagged data, I want to just clarify it by comparing it to sample field 55 response data. Can any one provide me sample response data of field 55 ?
In ISO8583 standard DE55 is allocated for EMV related data in request and response. In the response you can receive [ARPC][ARC] or [ARPC][CSU]. At times you can see template 71 or 72 which are issuer scripts with tag 9F18 optionally to identify the issuer script. Refer the payment scheme documentation for exact implementation details.
I run some load tests (all endpoints) and we do have a known issue in our code: if multiple POST requests are sent in the same time we do get a duplicate error based on a timestamp field in our database.
All I want to do is to count timeouts (based on the message received "Service is not available. Request timeout") in a variable and accept this as a normal behavior (don't fail the tests).
For now I've added a Response Assertion for this (in order to keep the tests running) but I cannot tell if or how many timeout actually happen.
How can I count this?
Thank you
I would recommend doing this as follows:
Add JSR223 Listener to your Test Plan
Put the following code into "Script" area:
if (prev.getResponseDataAsString().contains('Service is not available. Request timeout')) {
prev.setSampleLabel('False negative')
}
That's it, if sampler will contain Service is not available. Request timeout in the response body - JMeter will change its title to False negative.
You can even mark it as passed by adding prev.setSuccessful(false) line to your script. See Apache Groovy - Why and How You Should Use It article fore more information on what else you can do with Groovy in JMeter tests
If you just need to find out the count based on the response message then you can save the performance results in a csv file using simple data writer (configure for csv only) and then filter csv based on the response message to get the required count. Or you can use Display only "errors" option to get all the errors and then filter out based on the expected error message.
If you need to find out at the runtime then you can use aggregate report listener and use "Errors" checkbox to get the count of failure but this will include other failures also.
But, if you need to get the count at the run time to use it later then it is a different case. I am assuming that it is not the case.
Thanks,
I'm trying to get data from a spreadsheet (59 sheets) using this get request:
https://sheets.googleapis.com/v4/spreadsheets/{spreadsheetId}/values:batchGet
I have noticed that 40 ranges (sheets) is the limit before I get illegal request.
Does anyone know if this is normal behaviour and where it is documented?
I just found out that the issue has to do with the length of the url request. I shortened the name of the sheets and I could fit more into the request.
I've read conflicting and somewhat ambiguous replies to the question "How is a multipart HTTP request content length calculated?". Specifically I wonder:
What is the precise content range for which the "Content-length" header is calculated?
Are CRLF ("\r\n") octet sequences counted as one or two octets?
Can someone provide a clear example to answer these questions?
How you calculate Content-Length doesn't depend on the status code or media type of the payload; it's the number of bytes on the wire. So, compose your multipart response, count the bytes (and CRLF counts as two), and use that for Content-Length.
See: http://httpwg.org/specs/rfc7230.html#message.body.length
The following live example should hopefully answer the questions.
Perform multipart request with Google's OAuth 2.0 Playground
Google's OAuth 2.0 Playground web page is an excellent way to perform a multipart HTTP request against the Google Drive cloud. You don't have to understand anything about Google Drive to do this -- I'll do all the work for you. We're only interested in the HTTP request and response. Using the Playground, however, will allow you to experiment with multipart and answer other questions, should the need arise.
Create a test file for uploading
I created a local text file called "test-multipart.txt", saved somewhere on my file system. The file is 34 bytes large and looks like this:
We're testing multipart uploading!
Open Google's OAuth 2.0 Playground
We first open Google's OAuth 2.0 Playground in a browser, using the URL https://developers.google.com/oauthplayground/:
Fill in Step 1
Select the Drive API v2 and the "https://www.googleapis.com/auth/drive", and press "Authorize APIs":
Fill in Step 2
Click the "Exchange authorization code for tokens":
Fill in Step 3
Here we give all relevant multipart request information:
Set the HTTP Method to "POST"
There's no need to add any headers, Google's Playground will add everything needed (e.g., headers, boundary sequence, content length)
Request URI: "https://www.googleapis.com/upload/drive/v2/files?uploadType=multipart"
Enter the request body: this is some meta-data JSON required by Google Drive to perform the multipart upload. I used the following:
{"title": "test-multipart.txt", "parents": [{"id":"0B09i2ZH5SsTHTjNtSS9QYUZqdTA"}], "properties": [{"kind": "drive#property", "key": "cloudwrapper", "value": "true"}]}
At the bottom of the "Request Body" screen, choose the test-multipart.txt file for uploading.
Press the "Send the request" button
The request and response
Google's OAuth 2.0 Playground miraculously inserts all required headers, computes the content length, generates a boundary sequence, inserts the boundary string wherever required, and shows us the server's response:
Analysis
The multipart HTTP request succeeded with a 200 status code, so the request and response are good ones we can depend upon. Google's Playground inserted everything we needed to perform the multipart HTTP upload. You can see the "Content-length" is set to 352. Let's look at each line after the blank line following the headers:
--===============0688100289==\r\n
Content-type: application/json\r\n
\r\n
{"title": "test-multipart.txt", "parents": [{"id":"0B09i2ZH5SsTHTjNtSS9QYUZqdTA"}], "properties": [{"kind": "drive#property", "key": "cloudwrapper", "value": "true"}]}\r\n
--===============0688100289==\r\n
Content-type: text/plain\r\n
\r\n
We're testing multipart uploading!\r\n
--===============0688100289==--
There are nine (9) lines, and I have manually added "\r\n" at the end of each of the first eight (8) lines (for readability reasons). Here are the number of octets (characters) in each line:
29 + '\r\n'
30 + '\r\n'
'\r\n'
167 + '\r\n'
29 + '\r\n'
24 + '\r\n'
'\r\n'
34 + '\r\n' (although '\r\n' is not part of the text file, Google inserts it)
31
The sum of the octets is 344, and considering each '\r\n' as a single one-octet sequence gives us the coveted content length of 344 + 8 = 352.
Summary
To summarize the findings:
The multipart request's "Content-length" is computed from the first byte of the boundary sequence following the header section's blank line, and continues until, and includes, the last hyphen of the final boundary sequence.
The '\r\n' sequences should be counted as one (1) octet, not two, regardless of the operating system you're running on.
If an http message has Content-Length header, then this header indicates exact number of bytes that follow after the HTTP headers. If anything decided to freely count \r\n as one byte then everything would fall apart: keep-alive http connections would stop working, as HTTP stack wouldn't be able to see where the next HTTP message starts and would try to parse random data as if it was an HTTP message.
\n\r are two bytes.
Moshe Rubin's answer is wrong. That implementation is bugged there.
I sent a curl request to upload a file, and used WireShark to specifically harvest the exact actual data sent by my network. A methodology that everybody should agree is more valid than on online application somewhere gave me a number.
--------------------------de798c65c334bc76\r\n
Content-Disposition: form-data; name="file"; filename="requireoptions.txt"\r\n

wxPython

Curl, which everybody will agree likely implemented this correctly:
Content-Length: 250
> len("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")
500
(2x250 = 500, copied the hex stream out of WireShark.)
I took the actual binary there. The '2d' is --- which starts the boundary.
Please note, giving the wrong count to the server treating 0d0a as 1 rather than 2 octets (which is insane they are octets and cannot be compound), actively rejected the request as bad.
Also, this answers the second part of the question. The actual Content Length is everything here. From the first boundary to the last with the epilogue --\r\n, it's all the octets left in the wire.
I want to test how hotrod python client works. While testing i am facing an issue where i am not able to store any element whose message id in request header is 128. While checking the code of remotecache.py and init.py i found that HEADER_RES_FMT is set to ">BBBBB" for magic, msg_id, op_code, status and topology_mark. what i believe after going through documentation of hotrod protocol is, this format should be ">BLBBB" as datatype of message id vLong.
Also, i tried changing the format ">BLBBB", but then also it didn't work.
Any help will be appreciated.
Thanks,
Sonal
Looks like a bug in the client, already reported here: https://github.com/infinispan/python-client/issues/6
L won't work because the message id has a variable length (1 up to 9 bytes). I don't think struct.unpack can handle that, so the client should read the bytes one by one.
