I have a WebAPI service, written in ASP.NET (not Core), for which I am trying to generate documentation, in order to allow other devs to use it. I found Swashbuckle, and installed it. Then, since I also use OData for some of my services, I added Swashbuckle.OData. Then, I modified the CustomProvider setting in SwaggerConfig to use the ODataSwaggerProvider. I also set ResolveConflictingActions(apiDescriptions => apiDescriptions.First()) because I had a few Actions with the same URL path, differing only by query string (I'll need to address that later). So far so good.
Then, I tested it. I started my web app, then added "/swagger/" to then end. I got a message stating that it was loading the resource info. However, after several minutes, I got a browser error debug popup, stating "Error: Not enough storage is available to complete this operation." It asks if I want to debug, and if I do, it takes me to the debugger in IE (the browser I'm using). The only code in the stack is either from jquery-1-8-0-min-js or swagger-ui-min-js (this part confuses me, as there is no "swagger-ui-min-js" file in my project; I'm assuming it's embedded in the dll). There is no part of the stack trace that floats back up to my code, and all the code there is minified, so it's very difficult to debug.
However, I do know that it is at least partially working, as three of the controllers do show up in the resulting page after you close the error popup. You can navigate through them, and all the GETs, POSTs, PUTs, and DELETEs seem to be there, and you can test them.
Is it the case that whenever you navigate to the "/swagger/" url, Swagger hits all the URLs in the service, in order to generate the documentation? I'm wondering if maybe it is hitting an action that is taking a particularly long time to run, or possibly its generated documentation is taking too much disk space (I have plenty of space on my disk, but maybe it is referring to RAM?).
Anyway, even if that were not an issue, how can I get it to generate something, some kind of document file, that I can send off to someone? I see no new files added to my folders, so it would seem that it re-does the whole process every time you navigate to the swagger URL.
When I tried the Chrome browser, I no longer had the issue (I was using IE11 before). Not sure what the problem was, but this was the workaround.

I can't get the Google API to find my service account's credentials. I downloaded the necessary JSON file with the right name into the proper place, and I'm using Python code straight off the API documentation:
import gspread
gc = gspread.service_account()
sh = gc.open("Example spreadsheet (I'll replace this with my actual sheet name later)")
print(sh.sheet1.get('A1'))
The code stops at gc = gspread.service_account() with a FileNotFoundError. I discovered via an error message that this is because it's looking at the complete wrong file path (I think it's thinking I'm on a Mac when I'm actually on a Windows PC??). Overriding the file name, i.e.
gc = gspread.service_account(filename="insert\actual\path\here.json"),
does not work either, which is the mystifying part. I copied that path straight out of my file explorer, doubled the backslashes so Unicode doesn't try to escape it all (that happened once), tried every modification on the file path I could think of (%APPDATA%\gspread\service_account.json instead of the whole thing, etc.) - what could be going wrong?
Edit: #mods, feel free to close the question! I found the issue, which is that I was using the Repl.it online coding environment instead of a local one. I ported everything over to IDLE and it worked fine. I strongly suspect Repl.it just couldn't access my local files at all (I also tried it on Repl.it with a random screenshot in a different place, and it threw the same error).
I've edited some existing visual queries of Blog 4.0 application and when I was debugging it - it worked perfectly. But then on page it stopped working. Any attempt to use key with Data like Data["Posts"] raises System.Collections.Generic.KeyNotFoundException. App.Query["Blog Posts List"]["Posts"] returns something, but any attempt to access its fields raises another exception (don't remember the name, but it said that there's no such member inside that object).
I didn't rename queries, I didn't change application settings. I just edited logic of 2 queries. I renamed 1 wiring endpoint name across 3 queries in whole chain.
How do I debug it? How can I see what does cshtml receive from database so I don't guess and put my crystal ball away?
In general, App.Query["Name of Query"] will get you the streams of data. You usually need to convert it using AsDynamic() or AsList() to something you can work with.
This should help some; What is Data?
If you're just running into problems with field names, you probably forgot the AsList or AsDynamic, just like #accuraty-jeremy mentioned.
For real debugging, go to insights, you'll see what happens - but in your case it probably won't help, because your working with an object that's not dynamic (so doesn't support .FirstName) until you AsList/AsDynamic it.
My bad: I confused two different files - _List.cshtml and _List Paging.cshtml. So I was searching for an error in the code of wrong file.
I kick off 5 uploads (of varying size) via the BackgroundTransferService. I have the following questions about the way it works:
It seems that on the emulator it does 2 uploads at a time. Is this how it works on the actual device? Can I programmatically change this behavior?
Can I count on the uploads going out in the order that I submitted them? I seem to be getting conflicting results in my testing.
When I inspect the BackgroundTransferService in my application, does it contain requests from other apps as well or just mine?
Do I need to reconnect events for all the BackgroundTransferRequest objects when coming back from being tombstoned? What about coming back from being reactivated?
Do I need to disconnect events from the BackgroundTransferRequest when I remove it from the BackgroundTransferService.Requests collection?
When I try to upload a non-existing URL:Port (on the localhost), the TransferStatus is reported as WaitingForNonVoiceBlockingNetwork. The upload never actually completes/fails. Is this how it is on the device? Should I remove the request when it encounters this TransferStatus?
You cannot influence the behaviour of the BTS. If you don't like the way it works you can write the transfer functionality as part of your own application but then you have to handle running in the background yourself.
There is no guarantee on sequence.
The BTS may be handling requests from other apps but you won't be able to see the details. Requests() will only return details for your app.
Surely a quick test will tell you this.
It's good practice to.
Have you checked the TransferError property whe you reach this situation? This is a perfectly valild status in other situations and so you shouldn't treat this as a automatic fail.
Im pretty new to struts2 and Ajax ,Actually i have a drop down menu in JSP lets say first.jsp, When user select a choice from dropdown menu,I am calling a function of Action class lets say Method1.In this method i am fetching some value from DB(lets say:a,b,c) and one value from java memory lets say d.Then I am forwarding to second.jsp and display all the parameters(a,b,c and d) in tabular format.
Now problem is that the parameter d is dynamic ,this is updating by some other application and if its change then I have to show it on JSP wihout any action.
One solution is I use in second.jsp , so after interval of 10 second again Mehod1 will call and it will fetch value(a,b,c) from db and updated value of d from java memory. and disply it to second.jsp.But in this case i am unnecessary retrieving value from db while my purpose is just to get value d from memory.This is working but this is causing my application to slower.
Can any body suggetst some other solution? or can i do it using ajax and how?
Any other advice? any help is appreciated.try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic :I have spend hours trying to play around with this but have got nowhere
Okay... What you're asking is a little fuzzy so let me rephrase:
You have a user (USER1) who opens a web page and sees some data.
You have a second user (USER2) (who may be an application) who is able set a value from time to time.
When USER2 updates that value you want USER1 to see it change in their open browser window?
If this is the case you need to understand basic ajax. For that get these demo applications working:
This example uses dojo and perhaps the S2 ajax tag lib I don't remember I prefer not to use ajax tags (as they are deprecated and prefer jquery for ajax):
http://struts.apache.org/2.x/docs/struts-2-spring-2-jpa-ajax.html
This example here shows a very similar application but using jquery, no tag library, upgraded to Spring 3, it still needs polish:

Now that you know how to get data via ajax, look at the request with firebug. You'll see that the request is just like a typical function call, the browser keeps waiting for the data to come back.
What you do is simply not return from the action until new data is provided. This is called long polling see: http://en.wikipedia.org/wiki/Comet_%28programming%29#Ajax_with_long_polling
If you have not written a simple chat program, using just terminal windows I recommend you do so. Two windows per client (client-send, client-receive windows) and you'll need a server program. I remember hacking one together in a few hours using _Thinking In Java 2nd Edition (Later books took out the networking section if I remember correctly). Anyways between understanding client server interaction and long polling will let you get things working. It would be fun to extend the simple terminal based chat application to a S2 ajax chat application. Would make an awesome tutorial! PS: This is just an application of the producer/consumer problem (If you understand that then I guess you don't need to do the fun exercise).
The interfaces would look very pretty if the server was managed by spring. I know there must be nice servers already written but I am not familiar with any, but would love to hear of one.
I have written a Firefox extension that catches when a particular URL is entered and does some stuff. My main app launches Firefox with this URL. The URL contains sensitive information so I don't want it being stored in the history.
I'm concerned about the case where the extension is not installed. If its not installed and Firefox gets launched with the sensitive URL, it will get stored in history and there's nothing I can do about it. So my idea is to use a bookmarklet.
I will launch Firefox with "javascript:window.location.href='pleaseinstallthisplugin.html'; sensitiveinfo='blahblah'".
If the extension is not installed they will get redirected to a page that tells them to install it and the sensitive info won't get stored in the history. If the extension IS installed it will grab the information in the sensitiveinfo variable and do its thing.
My question is, can the bookmarklet call a method in the extension to pass the sensitive info (and if so, how) or can the extension catch when javascript is being called in the bookmarklet?
How can a bookmarklet and Firefox extension communicate?
p.s. The alternative means of getting around this situation would be for my main app to launch Firefox and communicate with the extension using sockets but I am loath to do that because I've run into too many issues over the years with users with crazy firewalls blocking socket communication. I'd like to do everything without sockets if possible.
As far as I know, bookmarklets can never access chrome files (extensions).
Bookmarklets are executed in the scope of the current document, which is almost always a content document. However, if you are passing it in via the command line, it seems to work:
/Applications/Namoroka.app/Contents/MacOS/firefox-bin javascript:alert\(Components\)
Accessing Components would throw if it was not allowed, but the alert displays the proper object.
You could use unsafeWindow to inject a global. You can add a mere property so that your bookmarklet only needs to detect whether the global is defined or not, but you should know that, as far as I know, there is no way to prohibit sites in a non-bookmarklet context from also sniffing for this same global (since it may be a privacy concern to some that sites can detect whether they are using the extension). I have confirmed in my own add-on which injects a global in a manner similar to that below that it does work in a bookmarklet as well as regular site context.
If you register an nsIObserver, e.g., where content-document-global-created is the topic, and then unwrap the subject, you can inject your global (see this if you need to inject something more sophisticated like an object with methods).
Here is some (untested) code which should do the trick:
var observerService = Cc['#mozilla.org/observer-service;1'].getService(Ci.nsIObserverService);
observerService.addObserver({observe: function (subject, topic, data) {
var unsafeWindow = XPCNativeWrapper.unwrap(subject);
unsafeWindow.myGlobal = true;
}}, 'content-document-global-created', false);
See this and this if you want an apparently easier way in an SDK add-on (not sure whether SDK postMessage communication would work as an alternative but with the apparently same concern that this would be exposed to non-bookmarklet contexts (i.e., regular websites) as well).
