I am using Redux-Sagas and here is what I am experiencing.
I am not sure if it is expected or not.
Every time the code trigger saga run a fetch command, it actually is showing two request.
I have custom header for the request.
I did try to remove x-custom-header and it showed one request.
What could be wrong here?
Thanks,
Please see screenshot
The first request is most probably an HTTP 'OPTIONS' (Preflight) request that is automatically done by the browser for cross origin requests.
Please see this article for an explanation: https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS#Preflighted_requests

I am submitting a request for data from the Binanance API as follows:
https://api.bscscan.com/api
?module=logs
&action=getLogs
&fromblock=24726622
&toBlock=24726632
&address=0x94084b7a8d80b2c3cc0dccd87cb6ae3cc67d364d
&topic0=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef
&apikey=JRYDR6FBWRKY5C8NMZJKFB8GEP1QHFQJQT
However, I can't get any data from this URL. I have double-checked, and I know that the parameters are correct.
Here is an example of using Binanace's API, which works well:
https://api.bscscan.com/api
?module=logs
&action=getLogs
&fromBlock=4993830
&toBlock=4993832
&address=0xe561479bebee0e606c19bb1973fc4761613e3c42
&topic0=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef
&apikey=YourApiKeyToken
Why is that working but mine not working?
I would highly suggest using Postman, which you can use to quickly test requests. I ran your request, with api-key, through Postman and was able to get a 200 response with data. See this screenshot.
Please note I blanked out the api key value. I suggest you do the same in your post unless its fake.
I had to remove the line breaks in the code you pasted. Could this possibly be the issue?
I need a tool which gives me a URL to make a HTTP request that will be recorded and it shows me what body was sent, which headers, which parameters, the method...
It's like something kind of opposite of Postman.
I tried to find such type of tool/service but didn't find any. If someone knows something similar, please let me know, thank you.
Actually, Postman has a feature which captures the request:
Enable it and just make the call to the set port (localhost:5555 by default) and it will be saved under the request history.
I am trying to get the (new) body from an edited issue comment. I don't know if I am missing something here, but it seems that the webhook payload returned with an edited issue comment, contains only the old comment... There is no way to tell what was changed.
What I do at the moment, is when I get an issue comment event with an action "edited", to make a get request for this comment in order to retrieve its body.
Is this how it's supposed to be? I find it strange that I need to make a new request for something that should already be in the issue comment payload.
There are some issues with webhook content returning old data, presumably due to caching and/or replication issues in GitHub's backend. GitHub support themselves have confirmed to me that this can happen.
The only workaround right now is to fetch the comment content in a separate API request after some small delay in order to allow the updated comment body to propagate through GitHub's backend (the bug affects API requests as well as webhook events, annoyingly).
I am developing a project which can disable a particular REST URI at runtime so that consumers will get an error. I have created interface/controller for disabling a URI. But I can not figure out how to disable it.
I thought of setting disable flag for the URI and sending blank data, but consumer needs to see an error.
I can not use Response every where.

Implement a ContainerRequestFilter(more on filters), which when a specific criteria is met will call:
ContainerRequestContext.abortWith(javax.ws.rs.core.Response)
with a proper HTTP status code.
I want to capture how parameters are being sent. Usually what I do is to make a request and check on Firebug's params tab what are the parameters sent. However, when I try to do this on the following site (http://www.infraero.gov.br/voos/index_2.aspx), it doesn't work - I can't see what are the parameters in order to repeat this request using curl. How can I get it? I'm not sure but I think that cookies are being used.
EDIT
I was able to get the request content, but couldn't understand it. It seems it uses javascript to generate the proper request. How can I reproduce this request via cURL?
Did you see this previous question cURL post data to asp.net page ? That might answer the question right there (all I did was search "ASP.NET cURL"). And this one: Unable to load ASP.NET page using Python urllib2 talks about Python, but it approaches it in a way that should translate to cURL.
But for my $0.02, I wouldn't bother trying to untangle ASP.NET's and __VIEWSTATE and javascript. Is it an absolute requirement that you use cURL?
I think you would be better off using a client that works more like a real browser and understands javascript. That's a bit of work, but it isn't as bad as it sounds. I've done this before with http://watirwebdriver.com/ and a short Ruby script. Here's how to do it with Python and Mechanize (this is probably a bit more lightweight).
http://phantomjs.org/ is another option that you script using javascript. If you Google "Scraping ASP.NET" you will see that this is a common problem.
You didn't say how you want it done, but you can send the request with curl simply with curl -d name1=contents1&name2=contents2 [TARGETURL] etc.
Note that you probably first need to fetch the main page and extract the "__VIEWSTATE" form field and submit back that (VERY huge) contents to get your submission accepted.
