I have been trying for the past several hours to make an authenticated request to the docker hub api. First of all, let me say that their documentation is very unclear. There are several different subdomains that you have to cycle through. The ones I have seen are index.dockerhub.io, registry-1.docker.io/v1/ auth.docker.com/token. There were others. But you get the point. Its like their api is managed by 30 different people or something and they forgot to have a meeting about how to unify their api. It feels like I have read just about everything I could find on the internet about how to do what I am trying to do, and it still is very unclear to me what I am supposed to do.
Their documentation states that I am supposed to get an auth token before making certain request. Ok. Fine. How do I do that? I got lucky and stumbled across the endpoint, https://auth.docker.io/v2/token/ no thanks to their api. I found it by just guessing. I don't know that version 2 is capable of even doing what I am trying to do.
What steps do I need to take to make authenticated request to the dockerhub api. What I am trying to do more specifically, is I am trying to query information about the given images that are on the hub, like the size of the images, and the basic port information that is available. I know its possible, because I have used services that do it. So, how do you properly authenticate request to get this information?
So after a few more hours of working on this problem, I came across someone who had similar issues and wrote a blog post about exactly how to solve it. The short answer is the endpoint that was missing from the docker api documentation is https://cdn-registry-1.docker.io/v1/. Why didn't they document their api better? I don't know. If anyone wants to read the full article about how this is done, you can find it at http://www.appcontainers.com/requesting-image-information-using-the-public-docker-api/
This was the most helpful article I have found on the subject. Hopefully this will help some other poor soul who is trapped in the confusion known as the docker api.

I would like to make a chat-bot for telegram, which, upon request, gives out a random post from the page of a certain community in vk.com social network.
Could somebody please tell me some thoughts about how to reach the solution?
May be the start question is "Is it possible to download all posts from the community feed in vk.com?"
Thanks!
I really don't know how to approach this problem.
I don't know if this is the right place to ask this question, but I have a problem with the Blockchain API V2, I tried too many times to request it, but never getting an answer nor my API!? I don't know why.
I searched the web looking for people whom having the same problem as I am, but find nothing. Also I didn't find a way to contact them asking about the delay in giving a simple API code!.
So if anyone has a better idea please let me know.
As an addition I am going to use it in a thirdparty software, where I am not able to add other Bitcoin payments instead of Blockchain one.
I don't know why exactly, but they have become extremely strict as to who they give API keys now. Previously it was very easy, and now they heavily investigate the intended usage. I wouldn't be surprised if the reason has to do with gambling sites and scams that were using their API.
As for recommendations you can run your own node on a VPS or use another 3rd party API. The only one that is as easy to use as blockchain.info, but actually gives out API keys is block.io. The catch is the free version is severely limited. There's also blocktrail, and blockcypher.
I'm working on a cloud project and I have to use Contrail it provides a RESTful API to use, but it is documentation is too small. I would like to know how to perform rest requests, especially post requests on "project" resource.
Each Contrail config node provides supported API details(searchable) at http://:8082/documentation/index.html
You could also check here which is a bit old but should serve your project API needs.
Your question is old, but as there are no other answers I thought I would contribute one. Were you interested in an answer or just wanted to share the documentation you'd written? I agree with you that Contrail documentation is very scarce, and every attempt to contribute to it should be appreciated. I had to integrate with Contrail API a while ago, and found out that in some cases I had to call OpenStack APIs to get the job done (Contrail is built on top of OpenStack). Project and user management were some of them.
I wrote a documentation about Contrail api, For each resource I mention the allowed methods and which parameters to integrate on the request body and I test it until I get it to work finally I put an example. I haven't finished the documentation, I stopped working on Open Contrail. The documentation is my personal try maybe it would be useful and maybe it contains some mistakes, Thus, I would like to share it. You can find it here.
I am having a problem here. I am totally new to this concept of servers and web services and being able to get data uploaded and retrieved on different devices, but I want to learn it, say if I want to create an app like Instagram.
But that is EXACTLY what I dont want, a link to a long tutorial on the internet on how to create the most complex app ever, I want to start slow. After doing extensive power searches on Amazon there are basically no books that will help me. So I want to start slow, here is my goal:
Get a great understanding of how web service backends and servers work and be able to apply it in other app ideas I have and want to start developing
I would like to start by being able to create an app that allows a user to enter some text into a field, it uploads to the server, another device can press a button to retrieve the text and display it in a text view.
I do not know php, and every single tutorial I have entered on this website is literal mindeff, the reason for this is because everyone has a different solution, sync web service backend with Core Data, MySQL, parse, Rails and it truly overwhelms me because I do not know which one to pick! And even worse some people provide code but I have no understanding whatsoever, and its like looking at a totally new language!
I am not asking for code, in fact that is the exact opposite. I am asking for someone to really lay out their knowledge, how does it all work? What is the best tool? Some resources and links. Nothing too complex...
I hope you can truly understand my extreme confusion and frustration. I think the reason might be is I might not be ready yet for all this, but I want to push forward and carry out my app idea!
Thank you...
Update:
I have finally decided on a web service I would like to use, it is the Amazon S3 web service, I am still not fully comprehending the full process though, any help or ideas!?
Since you wanted to create an Instagram-type app, look at this: http://www.raywenderlich.com/13511/how-to-create-an-app-like-instagram-with-a-web-service-backend-part-12
This is a good link to servers: http://www.youtube.com/playlist?list=PLC71D7CFB6AF935E6&feature=plcp. Watch the list to get an understanding of servers.
Maybe you want to read up on sql. Understanding sql will help.. Again: http://www.youtube.com/course?list=EC32BC9C878BA72085&feature=plcp. Watch the list to get an understanding of sql...
I can pass you the link and you got to do the work....
Hope this helps...
I am only just starting out with iPhone application development and have been doing some research with regards at getting data into an app using information available via the web.
I understand that I can access web pages using the NSURL* classes. Does anyone know how I might request data from a page that requires user input?
I can understand accessing an actual page, but I am not sure if (or how) I might be able to initiate the request and get the appropriate data back into my app.
Any help / pointers is very much appreciated.
EDIT_001:
I was thinking that I would have to interact with the actual controls on the page, but after a little more investigation I have found that I can simply use the request HTML that the page generates.

This question is really too broad ("how does http networking work"), and if you look around this site you will probably find several questions that will take you in the right direction. As a first stop, check out the ASIHTTPRequest framework. Many people use it, and it makes http networking really simple.
You could also have a look at these links for inspiration:
