I wrote a simple API which will return request.query as a response.
The behavior is little different than what I am expecting.
redirectto -- I am getting the only name as part of response redirectto param.
id -- I am getting an array in response.
Why is this behaviour?
Query parameters that contain reserved characters should be URL encoded or they will fail to parse correctly.
The properly encoded URL should look something like this:
http://localhost:8082/redirect?requesttype=click&id=79992&redirectto=http%3A%2F%2Flocalhost%3A8081%2Fredirect%3Fname%3Djohn%26id%3D123

I am using mockoon for API simulation. I created 2 routes there with method GET and its body contains(responds with) JSON object. I noticed that my express app is not able to parse one of the routes. But the route that has JSON object in body which contains ARRAY is getting parsed. I tested both routes with Express(by console.log) and in chrome browser(I have JSON formatter extension) and it is behaving the same meaning response that does not contain ARRAY is not getting parsed but the response with array is getting parsed(behaving normally). Let me show the screenshots:
Express(by console.log):
With array:
Without array:
Chrome(JSON Formatter extension):
With array(extension is able to parse):
Without array(extension is not able to parse):
I tried adding Header(Content-Type: application/json) to the route in mockoon. But still, I am not aware of what is going on here. Someone please explain
The express code:
const iabs_client = await axios.get(
"http://localhost:3001/iabs-client
);
Here is the route created in Mockoon(without array inside JSON):
P.S mockoon is a program that creates endpoints in localhost, useful for API simulation when developing front-end without having backend yet
The trailing comma after "something" is not valid JSON. Edit your Mockoon body to remove the comma and it should work.
I'm trying to send a request to my Nestjs application, with just plain string in the request body, for example:
test23+Se5+345
Then in my application, I have a middleware, where I need to do something with this string.
The problem is when I access request body in middleware const requestBody = Object.keys(req.body)[0];, this string looks like this:
test23 Se5 345
All of the + symbols are substituted by
I don't have additional convertings before this, and I know that middleware runs first in the request lifecycle. I think maybe there is some issue with body-parser, but I don't know yet how to fix this.
This is because symbol + is treated as space, so before send it, you need to encode your + characters to %2b. More here: How to encode the plus (+) symbol in a URL
I'm trying to make a query to Here Maps API with JavaScript to calculate a route with waypoints, where the waypoints are of type "passThrough", the actual produced URL is (I just removed the API key):
https://router.hereapi.com/v8/routes?xnlp=CL_JSMv3.1.21.3&apikey={API_KEY_HERE}&routingMode=fast&transportMode=truck&origin=25.900672%2C-80.253709&destination=40.213615%2C-97.188347&unit=imperial&truck=%5Bobject%20Object%5D&return=polyline%2CtravelSummary&via=40.052839%2C-87.410475!passThrough%3Dtrue
This query returns an error response, even when I'm following the documentation. Here is the problem I found,
If I paste this URL in the browser and remove "%3D" after "passThrough" from the URL, and explicitly change it to "=", the API then returns the expected response. Have to clarify that the URL from above works with curl -X GET. So I really think that the Here Maps API is not decoding the URL, even when they say that special characters have to be encoded.
Any clue on this?
Am I wrong?
I'm having an issue with a NodeJS REST api created using express.
I have two calls, a get and a post set up like this:
router.get('/:id', (request, response) => {
console.log(request.params.id);
});
router.post('/:id', (request, response) => {
console.log(request.params.id);
});
now, I want the ID to be able to contain special characters (UTF8).
The problem is, when I use postman to test the requests, it looks like they are encoded very differently:
GET http://localhost:3000/api/â outputs â
POST http://localhost:3000/api/â outputs â
Does anyone have any idea what I am missing here?
I must mention that the post call also contains a file upload so the content type will be multipart/form-data
You should encode your URL on the client and decode it on the server. See the following articles:
What is the proper way to URL encode Unicode characters?
Can urls have UTF-8 characters?
Which characters make a URL invalid?
For JavaScript, encodeURI may come in handy.
It looks like postman does UTF-8 encoding but NOT proper url encoding. Consequently, what you type in the request url box translates to something different than what would happen if you typed that url in a browser.
I'm requesting: GET localhost/ä but it encodes it on the wire as localhost/ä
(This is now an invalid URL because it contains non ascii characters)
But when I type localhost/ä in to google chrome, it correctly encodes the request as localhost/%C3%A4
So you could try manually url encoding your request to http://localhost:3000/api/%C3%A2
In my opinion this is a bug (perhaps a regression). I am using the latest version of PostMan v7.11.0 on MacOS.
Does anyone have any idea what I am missing here?
yeah, it doesn't output â, it outputs â, but whatever you're checking the result with, think you're reading something else (iso-8859-1 maybe?), not UTF-8, and renders it as â
Most likely, you're viewing the result in a web browser, and the web server is sending the wrong Content-Type header. try doing header("Content-type: text/plain;charset=utf-8"); or header("Content-type: text/html;charset=utf-8"); , then your browser should render your â correctly.
I am using url module, which basically splits a web address into readable part.
var data = url.parse(request.url).pathname
the output of request.url is C:\AppFolder\dropbox\videos\myVideo8#.MP4. After its get parsed, I dont understand why its not returing the value with "#.MP4"
I dont understand why its not returing the value with "#.MP4"
Because #.MP4 is the fragment and not the path component of the URL. (You can read up on URL syntax f.e. on WikiPedia, if you are not sure: https://en.wikipedia.org/wiki/URL#Syntax)
You want to look at hash, not pathname https://nodejs.org/docs/latest/api/url.html#url_url_hash
