Is there a way to get the system time (say as long-timestamp) of a Jenkins deploy using the Rest API. In my case I was looking at JSON.
If nothing else, every HTTP response should have a Date header which will be the server-side time. You wouldn't need any authentication for this, a simple HEAD request for the homepage would do the job.

I have a Rails API which can handle requests from the clients. Clients use that API to perform analysis of their data. Client POSTs the data to API, API checks if that data have been analysed before. If so API just respond with analysis result. If the data haven't been analyzed before API:
Tells client that analysis started.
Establishes the connection with analyzing microservice.
Performs asynchronous (or deferred or i don't know) request to the analyzing microservice and waiting for response. The analysis takes much time so neither the API nor the microservice should be blocked while doing it.
When the response from analyzing microservice is returned API hands it to the client.
The main issue for me is to set up things such way that client could receive somehow the message "Your data had been sent to analysis" right after he performed the request. And then when analysis will be done client could receive its result.
The question is what approach I have to use in that case? Async responses, deferred responses, something else? And what known solutions could help me with that? Any gems?
I'm new to that stuff so I'm really sorry if I ask dumb questions.
If using HTTP you can only have one response to every request. To send multiple responses, i.e. "work in progress", then later the "results", you would need to use a different protocol, e.g. web sockets.
Since HTTP is so very common I'd stick with that in combination with background jobs. There are a couple of options which spring to mind.
Polling: The API kicks off a background jobs (to call the microservice) and responds to the client with a URL which the client can ping periodically for the result. The URL would respond with some kind of "work in progress" status until the result is actually ready). The URL would need to include some kind of id so the API can lookup the background job.
The API would potentially have two URLS; /api/jobs/new and /api/jobs/<ID>. They would, in Rails, map to a controller new and show action.
Webhooks: Have the client include a URL of its own in the request. Once the result is available have the background job hit the given URL with the result.
Either way, if using HTTP, you will not be able to handle the whole thing within a request/response, you will have to use some kind of background processing (so request to the microservice happens in a different process). You could look at Sidekiq, for example.
Here is an example for polling:
URL: example.com/api/jobs/new
web app receives client request
generates a unique id for the request, SecureRandom.uuid.
starts a background job (Sidekiq) passing in the uuid and any other parameters needed
respond with URL such as example.com/api/jobs/
--
background job
sends request to microservice API and waits for response
saves result to database with uuid
--
URL: example.com/api/jobs/UUID
look in database for UUID, if not found respond that job is "in progress". If found return result found in database.
Depending on what kind of API you use. I assume your clients interact via HTTP.
If you want to build an asynchronous API over HTTP the first thing that you should do: accept the request, create a job, handle it in the background and immediately return.
For the client to get the response you have to 2 options:
Implement a status endpoint where clients can periodically poll the status of the job
Implement a callback via webhooks. So the client has to provide a URL which you then call after you're done.
A good start for background processing is the sidekiq gem or more general ActiveJob that ships with Rails.
I am creating a rest api with redstone and dart.
Now I need to create a way to send several commands of the api in one POST.
Edit (#Pacane): Yes, the idea is to have one endpoint that can parse several commands within the api. Each command is another endpoint(Route) that can be accessed singularly within the API.
My question is how I can parse, executes the URLs and get the response for each URL using redstone.
I am thinking about using the unittest mock request and mock response. You can see here:
https://github.com/redstone-dart/redstone/wiki/Unit-test
Now I wonder if the mock request and response are different somehow from regular requests, if they use some analysis or something like it that would harm performance.
So, there are 2 questions:
1) is it ok to mock the redstone to parse several URLs?
2) if not, how could I do it?
thanks
I ended up using the MockRequest and MockResponse to achieve the batch commands. You can know more about it at the wiki: https://github.com/redstone-dart/redstone/wiki/Unit-test
Trying to automate my test cases using jmeter. I have used cxf for rest apis on my web server. I have an api which actually takes a java object as parameter. On jmeter I have selected the POST method under HTTP-request and sending json data in Body data. The api gets called fine. However the parameter comes null and hence by api fails. I did try changing the parameter to String object, however I get this string as null.
Is this the right way to call apis via jmeter. Or is this failing because I have used cxf on my server.
Any help is appreciated.
Thanks
Most likely you need to add a HTTP Header Manager and configure it to send Content-Type header with the value of application/json
See Testing SOAP/REST Web Services Using JMeter for detailed explanation on JMeter configuration for REST API testing.
Other thing you could try out is using SoapUI tool to send the request to your CXF endpoint and if it succeeds - inspect the request and configure JMeter accordingly. By the way, SoapUI has some limited load testing capabilities, may be it will be enough for your scenario
We have two jira installations at our company. One that we use for our projects and a second one for testing purposes.
I'm working in a project that needs to use the JIRA REST API. For this purpose I'm connecting to our testing instance.
The problem is that while trying out the REST API, I keep getting 400 errors without a single explanation of what went wrong. I just get an HTML with
Your browser sent a request that this server could not understand
I was a bit desperate and decided to try it into our real JIRA. To my surpirse the same request gave me a different response:
{"errorMessages":[],"errors":{"project":"project is required"}}
In this case, I do get a meaningful error!
I replicated this easily. I would never get a meaningful error from the test instance, but the real one will always give me one.
I cannot keep trying out stuff in our productive JIRA, but I cannot easily continue working without getting meaningful errors. So, what could be wrong in the testing instance? I could not find any configuration about the 'verbosity' of the API responses.
I believe that this error is returned not by JIRA but rather by proxy web server that is part of you production configuration.
I suggest you to compare HTTP headers that are sent with working requests from your browser with headers you pass via curl. Googling for the "Your browser sent a request that this server could not understand" helps too
How to get response of seperate ajax requests in a web page using capybara-webkit?
Is there any particular method available to capture response time of each request?
Note:
Am using capybara with rspec.
For eg: i have 3 Ajax requests in a web page. I need to get separate response time of each request and the response time of entire web page.
Thanks,
Priya
Generally it's not possible since webserver is running in the different process but you could create a custom rack middle-ware and dump all responses to the separate log file. For the beginning you could implement technique described here: https://gist.github.com/2975611 and for dumping headers you could use some code snippets from http://rack.rubyforge.org/doc/Rack/ContentLength.html
