I'm a newbie and have little knowledge, I apologise in advance.
I have been trying to find examples on making subsequent post requests using data from the first request.
Scenario, making a request to obtain an auth token which will then be used on subsequent requests in the header.
E.g. request 1 is a POST and returns an access_token object
request 2 is a POST and requires the access_token object from request 1 in the headers.
I have successfully made the request 1 with request-promise but don't know how to pass that to the 2nd requests options.
Thanks
Look into "promise chaining". You should make the second request in the .then((resp) => ...) callback, where you have access to the response data from the first request. If you return the second request promise, you can continue the chain.

Currently building a RESTful API with express on my web server, and some routes like the delete route for a document with mongoose ex. await Note.findByIdAndRemove(request.params.id) response.status(204).end() send response statuses with end()
Why do I need to add the .end()? What in these cases, and why cant one just send response.status(204)
With some responses that return json, the response.status(201).json works fine
Only certain methods with Express or the http interface will send the response. Some methods such as .status() or .append() or .cookie() only set state on the outgoing response that will be used when the response is actually sent - they don't actually send the response itself. So, when using those methods, you have to follow them with some method that actually sends the response such as .end().
In your specific example of:
response.status(204)
You can use the Express version that actually sends the response:
response.sendStatus(204)
If you choose to use .status() instead, then from the Express documentation, you have to follow it with some other method that causes the response to be sent. Here are examples from the Express documentation for .status():
res.status(403).end()
res.status(400).send('Bad Request')
res.status(404).sendFile('/absolute/path/to/404.png')
Since all three of these other methods will cause the response to be sent and when the response goes out, it will pick up the previously set status.
I am trying to get data from Uni Stats API by sending a get request. Following is my code:
import requests
dt = requests.get(url='https://API_TOKEN#data.unistats.ac.uk/api/v4/KIS/Institution/10007856.json')
print(dt)
Whenever I run this code it returns me <401 Response> but If I try the same url https://API_TOKEN#data.unistats.ac.uk/api/v4/KIS/Institution/10007856.json in the Postman software it returns correct data in json format.
So I wanted to know how can I send a get request with requests which can return correct data?
requests.get('https://data.unistats.ac.uk/api/v4/KIS/Institution/10007856.json', auth=('user', 'pass'))
401 is an authorization error, provide authorisation to the request.get method.
Depending on your user agent, you may be able to include the access token in the url as in the following examples:
https://accesstoken#data.unistats.ac.uk/api/v4/KIS/Institution/{ukprn}/Course/{kisCourseId}
Emphasis added.
I have the koa-router-forward-request set up. I make an axios call to it and that call is forwarded onto an API. I can do get requests and retrieve the information. I can't get post requests working. I want to forward the post request body from the original axios call onto the API how do I do that?
I have const composeRequest = body;
and in the request I have composeBody: composeRequest as an attribute but that does not seem to be working.
This is super late but I think what you are looking for is maybe to 1. ensure you are using bodyParser() i.e. router.use(bodyParser()) and 2. when hitting the Koa route pull any params you pass via Axios by ctx.request.body, all params should be stored in there to pull out.
I defined my_function inside app.post('/someRoute',my_function) in nodejs which is used for making an http-request(posting data) to another server.
However it seems that my_function will run twice when I do not defined any response to the browser inside my_function.
What will be the reason for this? And is it required to send a response in every request no matter GET or POST in nodejs?
Thanks!
Whenever you do not define a response to a function/route handling get or post requests, the request response cycle will not end and thus the request keeps running until it times out because it took too long to get a response from the server. It is thus important to define a response to every request.
I'm trying to validate a webhook via facebook. So facebook hits my url my-url/facebook/receive within my route in nodejs i'd do res.send(req.query['hub.challenge']); to send an http response.
I'm using KoaJS. From what i understand, Koajs merges the request and response object into ctx but when reading through the docs I can't find anything along the lines of ctx.send or similar to send a http response.
Can anyone give me some direction or links.
Thanks.
To send the body of a response, you can simply do ctx.response.body = 'Hello'. There are many aliases attached to ctx, so you don't necessarily have to reference the response or request yourself. Doing ctx.body = 'Hello' would be the same as the code above.
If you wanted to set headers, you would use the ctx.set() method. For example: ctx.set('Content-Type', 'text/plain').
To access the query parameters, you would use ctx.request.query['some-key'] (or simply the alias ctx.query['some-key']).
All of the different request/response methods are documented pretty well at the Koa website along with a list of aliases attached to ctx. I highly recommend you give it a read.
