Answered 2021-Mar-29 at 14:04So I ended up writing a simple jquery plugin to handle this, and it is shared here on github.

It does not care about whether an image is on screen or not, because for my use-case it is nice to have, not need to have.

In order to satisfy a security audit, I need to implement a feature where a user can have at most 3 attempts of login per 5 minutes
fortunately, it is now built-in Symfony 5.2: https://symfony.com/blog/new-in-symfony-5-2-login-throttling
As the parameter max_attempts
is not enough for me (it's per 1 minute), I want to use the second option to provide my owner limiter
so I use this https://symfony.com/blog/new-in-symfony-5-2-rate-limiter-component
my configuration looks like this

it's the vizier of dynamic memory allocation reporting in again. I know it's generally frowned upon to provide the entire example, but I've been working through several problems on leetcode, and have found that I always have the same problem, and that is shadow bytes. I haven't been able to identify exactly what it is I'm doing wrong, because the error messages, and their driver program for the testcases is somewhat hidden, but if someone, for this simple example, could explain what I'm doing wrong, it would be appreciated:

QUESTION
In Spring cloud Gateway request timeout for path in not working as expected.
I tried to specify global timeout, but its not working as expected.
I am trying to call a microservice A. In A microservice I have added an delay to 5 sec.
Now in path if I add response timeout as more than 5s, it should wait for the response, but currently circuit breaker is opened and currently its returning the fallback message in 1000ms
I have configured resilience4j circuit breaker in gateway.
I am not able to understand why response timeout for Path and global timeout not working.
application.yml
...ANSWER
Answered 2020-Dec-03 at 06:04I found that we need to define Timelimiter with Circuit Breaker, and default timeout is 1 Sec

ANSWER
Answered 2020-Oct-25 at 12:49I know two options:
- Create a rate limiter with 1,000,000,000 points. Consume depending on usage plan: freemium consumes 10,000,000 points per request, silver plan consumes 1,000,000 per request, gold plan consumes 1,000 points per request, etc. Delete previously consumed points by IP, when a new plan bought.
- Create separate rate limiter for each plan with different amount of points. Consume from appropriate rate limiter depending on user's plan.
QUESTION
I am writing an API wrapper in TypeScript. I would like the code to be asynchronous in order to maximally meet the rate limit of the API in question. The API wants requests to be submitted at a maximum rate of 1/second.
I intend to implement an API wrapper which is instantiated once, and allows the use of objects to reach the different endpoints. For instance, within the greater API there is a post
and pool
endpoint. I would like to access them like post_object.post.submit_request(argument1, ...)
or post_object.pool.submit_request(argument1, ...)
.
I have created an object called state_info
which is passed between the various objects, within which is contained a user-agent header, login information if provided, and a rate-limiter object from the Bottleneck library.
The issue I'm running into while testing is that my program doesn't seem to actually be limiting the rate of requests; no matter what I change the limit to in the arguments for Bottleneck, the requests all happen in about .600 seconds every time.
I am thinking this has something to do with passing around the rate-limiter object, or in accessing it from multiple places, but I'm unsure.
First, here is the code for the Model
object, which represents access into the API.

It turns out, in the "gotchas" section of the bottleneck API reference they note:
If you're passing an object's method as a job, you'll probably need to bind() the object:

QUESTION
I'm trying to make several requests to the BoardGameGeek (BGG) API and after a certain amount of requests within a certain time frame, I get timed out (status code 429). I've tried a couple of libraries to try and get this to work.
I've tried using the simple-rate-limiter library as below, but this didn't work because BGG seems pretty aggressive with their rate limiting and they don't publish official limits anyways.
...ANSWER
Answered 2020-Jul-29 at 00:14This solution is specifically for the BoardGameGeek API.
So instead of doing a bunch of individual requests such as:
/xmlapi2/thing?stats=1&id=188920
/xmlapi2/thing?stats=1&id=174476
You can batch them all into one request like this:
/xmlapi2/thing?stats=1&id=188920,174476
This means that you're only sending off 1 request and will not get rate limited.
I did find out that this still does fail if you attach over ~1200 game ids though. The server responds with 414 Request-URI Too Large
.
Here's an example of that error.
If you need more then 1200 then you'll probably have to split the game ids and make multiple requests so that you only request 1200 at a time.

I have seen similar questions but nothing I have seen in the documentation or stackoverflow describes what I am trying to do. I am new to javascript and just started using jest, I have read through the jest documentation but I have not seen an example that mocks a named export of an external library. The library I am trying to mock is rate-limiter-flexible. I want to mock the named export RateLimiterRedis. I need to mock a couple of RateLimiterRedis functions, including get, consume, and delete.
For example when I mocked a function from redis all I had to do was:

Answered 2020-Jun-24 at 20:54The export of rate-limiter-flexible
is an object that is supposed to have RateLimiterRedis
function that returns an instance that has get
method.
"I have tried" snippet is wrong because it makes RateLimiterRedis
function to return another function, and RateLimiterRedis
itself isn't a spy so it cannot be asserted.
It should be:
QUESTION
I'm using socket.io and used rate-limiter-flexible and limiter to limit request rate, but I noticed the route /socket.io isn't receiving 429 from either, in fact, I can't log any requests coming from this route by using app.use('/socket.io')..
I think socket.io is doing some treatment on this route under the hood, is that correct? If so, how can I make sure requests to /socket.io also receive 429 after the limit is reached?
Rate limiter on Connect:
...ANSWER
Answered 2020-May-15 at 18:01Socket.io attaches itself to your http server by inserting itself as the first listener to the request
event (socket.io code reference here) which means it totally bypasses any Express middleware.
If you're trying to rate limit requests to /socket.io/socket.io.js
(the client-side socket.io code), then you could create your own route for that file in Express using your own custom router with a different path and have your client just use the Express version of the path and you could then disable serving that file through socket.io (there's an option to disable it).
If you're trying to rate limit incoming socket.io connections, then you may have to modify your rate limiter so it can participate in the socket.io connect event.
Now that I think of it, you could hack the request
event listener list just like socket.io does (you can see the above referenced code link for how it does it) and you could insert your own rate limiting before it gets to see the request. What socket.io is doing is implementing a poor man's middleware and cutting to the front of the line so that they can get first crack at any incoming http request and hide it from others if they have handled it. You could do the same with your rate limiter. Then, you'd be in an "arm's race" to see who gets first crack. Personally, I'd probably just hook the connect
event and kill the connection there if rate limiting rules are being violated. But, you could hack away and get in front of the socket.io code.

Install rate-limiter
You can use rate-limiter like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the rate-limiter component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
