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.

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
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.
I see a lot of useful methods in the API, but I don't find any method to list all my Posts, or all the posts from within a publication. Is this intentional?
Thought it would be something really obvious to exist in the API. Or am I missing something?
Got it, just use the RSS feed instead.
I wrapped a Github package by #mark-fasel into a Clay microservice that enables you to do exactly this:
Simplified Return Format:
https://clay.run/services/nicoslepicos/medium-get-users-posts-simple
What Medium actually returns at the endpoint
https://clay.run/services/nicoslepicos/medium-get-users-posts
I put together a little fiddle, since a user was asking how to use the endpoint in HTML to get the titles for their last 3 points:
https://jsfiddle.net/h405m3ma/1/
You can call the API as:
curl -i -H "Content-Type: application/json" -X POST -d '{"username":"nicolaerusan"}' https://clay.run/services/nicoslepicos/medium-get-users-posts-simple
You can also use it easily in your node code using the clay-client npm package and just write:
Clay.run('nicoslepicos/medium-get-users-posts-simple', {"username":"usernameValue"}) .then((result) => {
// Do what you want with returned result console.log(result);
})
If you need to generally pull down an RSS feed, here's a microservice for that:

Is it possible to send a GET and POST request using curl through a linux terminal?
Essentially, I'm trying to understand what these guys are doing in this tutorial but I don't understand how to add additional GET parameters to their tutorial's example.
For instance, in their tutorial (http://valeriobasile.github.io/candcapi/), they use the example of:
curl -d 'Every man loves a woman' 'http://gingerbeard.alwaysdata.net/candcapi/proxy.php/raw/pipeline?semantics=fol'
It works but I want a graphical representation of this. They also mention this in their example Here.
"An entry point to generate a PNG image...
$CANDCAPT/drg
"The URL accepts the same GET parameter as pipeline."
So I tried to send this but it doesn't get a PNG file:
curl -d 'Every man loves a woman&pipeline' 'http://gingerbeard.alwaysdata.net/candcapi/proxy.php/raw/pipeline?semantics=drs&roles=verbnet'
This actually breaks their system.
curl -d 'Every man loves a woman' 'http://gingerbeard.alwaysdata.net/candcapi/proxy.php/raw/pipeline?semantics=drs&roles=verbnet%20%#d%2dbox'
So my question is, I'm not too sure what the developers mean when they say the url accepts the same GET parameters and how would I add that in? Please let me know if you have any ideas, thanks.
EDIT 1 -
I tried adding drg instead of pipeline but it returns a message saying, "not found"
curl -d 'Every man loves a woman' 'http://gingerbeard.alwaysdata.net/candcapi/proxy.php/drg?semantics=fol'
I read through the GitHub documentation, and at the bottom it describes how to obtain graphical output:
The C&C/Boxer API provides an entry point to generate a PNG image of the DRG of a given text:
$CANDCAPI/drg
The URL accepts the same GET parameter as pipeline and returns a raw PNG file.
Based on this, your GET url should look something like this:
http://gingerbeard.alwaysdata.net/candcapi/proxy.php/drg?semantics=fol
Using the "same" GET parameters means that whatever you passed to the pipeline after the question mark can also be passed to the drg web service.
Modified anwser:
Here's the correct command from the same example:
curl -d 'Every man loves a woman' 'http://gingerbeard.alwaysdata.net/candcapi/drg?semantics=fol'
And for people who are beginners like me, here's to save the png file:
curl -d 'Every man loves a woman' 'http://gingerbeard.alwaysdata.net/candcapi/drg?semantics=fol' >> image.png
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.
