Does YouTube support oEmbed? - youtube

This suggests it does :
https://youtube-eng.googleblog.com/2009/10/oembed-support_9.html
But I'm getting nothing back when I do, say
curl "https://www.youtube.com/oembed" -d 'format=json' -d 'url=https://www.youtube.com/watch?v=uXBDgLglFig'
Does anyone know if the oembed API has been deprecated?

You're making a POST request with those options you're passing to curl. You need to make a GET request instead, like so:
curl 'https://www.youtube.com/oembed?format=json&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DuXBDgLglFig'
Note that the URL parameter must be URL encoded. How you do that depends on what language you're using to make the request.

mediawiki API does not see the csrf token

When running my own mediawiki on localhost I run into a problem with the api endpoint for editing a page. The api works fine otherwise. For instance when querying tokens I get the following output:
$ curl "http://localhost/api.php?action=query&meta=tokens&type=createaccount|csrf|login&format=json"
{"batchcomplete":"","query":{"tokens":{"createaccounttoken":"1e5c2ce3f9e12fdab05a0e6e6352da3162644214+\\","csrftoken":"+\\","logintoken":"35ee2e6ccbbd654bcfada9cddab07f7662634214+\\"}}}
Interestingly the csrftoken has the strange value '+\\', which also seems to be appended to the logintoken.
When posting an edit action (for an existing page called Alice) with this token I get the reponse that the token is missing from the post body. But it's not missing, or is it?
$ curl -X POST "http://localhost/api.php?action=edit&title=Alice&summary=test&text=article&baserevid=0&token=+\\&format=json"
{"error":{"code":"mustpostparams","info":"The following parameter was found in the query string, but must be in the POST body: token.","*":"See http://localhost/api.php for API usage. Subscribe to the mediawiki-api-announce mailing list at <https://lists.wikimedia.org/postorius/lists/mediawiki-api-announce.lists.wikimedia.org/> for notice of API deprecations and breaking changes."}}
Then I followed this advice and added the cookie-jar option to make the curl request from the same session, but it gave the same error response. Any ideas?
By the way I used the docker.io/bitnami/mediawiki:1 docker image together with a mariadb to set up my mediawiki.
The following parameter was found in the query string, but must be in the POST body
I'm not very familiar with curl but it seems that you are sending a post request with the params in the query part. Try sending them in the post body as the error suggests:
curl --data "action=edit&title=Alice&summary=test&text=article&baserevid=0&token=+\\&format=json" http://localhost/api.php

Posting attachments to Slack API

So I just understood that the Slack Web API does not support JSON data over POST. Which means I have to encode my complex and nested JSON object to fit in query parameters over GET. Problem is, the attachements don't seem to work. Does anyone have a solution ?

I'm not sure I follow what you mean. You can certainly use POST. The body of a Slack API call should be form-encoded, but parameter values are sometimes JSON (as is the case for attachments).
Here's a working curl command that uses HTTP POST to post a message with a simple attachment.
$ curl -d token=<REDACTED> -d channel=<REDACTED> \
-d text="This is the main text." \
-d attachments='[{"text": "This is an attachment."}]' \
https://slack.com/api/chat.postMessage
I'd recommend using POST, but GET also works fine. If you fill in the values in https://api.slack.com/methods/chat.postMessage/test, the tool will give you a URL at the bottom that you can use with HTTP GET.

Constructing an HTTP POST request using Curl and Postman

I have been using curl & Postman on Chrome to send http POST requests with one variable to an simple HTTP server I have running and I have noticed that they construct the requests slightly differently. Apologies if I might have used any incorrect terminology in constructing the question - I'm still learning this stuff.
Using Postman, the request is constructed by putting a '?' between the resource name and the variable. E.g.
http://192.168.0.2:9999/1/command?a=b
However, the following curl command:
curl -X POST http://192.168.0.2:9999/1/command --data a=b
does not put a '?' between the resource name and the variable.
The result is that the HTTP server interprets the requests differently.
In the first case, the body of the request is empty and in the second case the body contains a=b.
Which version is correct?
Constructing curl , python request , using HTTP POST
Open postman client and click on code [Below save button ] refer snapshot .
when click on code another window appears . refer snapshot .
similarly you can generate various other request [curl , python ,java , php ] refer snapshot
You can refer below link
http://jmeterblogb.blogspot.in/2016/11/constructing-curl-from-python-http-php.html
POST requests post data as part of the request body and GET requests via URL parameters. If you choose the form data option in postman you can pass it the same way (request body) in postman as well. How are parameters sent in an HTTP POST request? may be worth reading.

pass URL-encoded URL to CURL

How do i pass a URL-encoded URL to CURL?
Ex:
curl "http://live.nwk5.net/secure/v.stream/playlist.m3u8?expiry=kFmysuf%2fLjOqgdXGJWqFQA%3d%3d"
This returns a invalid page.
if I URL decode the parameter as below, Im getting the expected response. Please Help.
curl "http://live.nwk5.net/secure/v.stream/playlist.m3u8?expiry=kFmysuf/LjOqgdXGJWqFQA=="
You're talking in vague terms. curl accepts and expects a URL. You need to provide the correct URL as curl can't guess what you otherwise intended.
If you have the URL encoded into weirdness, you have to first decode it to tell curl the correct URL.
URL-encoding a URL an extra time like you seem to have done partly (because otherwise you would also have encoded the slashes etc), is what I consider "encoded into weirdness".

query string not fully read in rails

i have ruby on rails based api which accepts a get request.
example :
http://localhost:3000/api/search?query=whatis&access_token=324nbkjh3g32423
when i do curl from mac terminal like
curl http://localhost:3000/api/search?query=whatis&access_token=324nbkjh3g32423
i checked in the server with "request.fullpath", it return only "/api/search?query=whatis", the second parameter is missing.
however if i do curl like
curl --data="query=whatis&access_token=324nbkjh3g32423" http://localhost:3000/api/search
it is taking all the parameters.
i understand there is a problem with encoding, but i what to know what difference is there with the two requests.
Thanks in advance
The problem probably is that bash shell sees & as the end of the command.
try quoting the entire querystring like this -
curl "http://localhost:3000/api/search?query=whatis&access_token=324nbkjh3g32423"
