Obtaining Weather Data From NOAA - weather

I am trying to use the API to return data from the Chagrin Falls station in Ohio. I can get the data from the website so I know there is data, but the API does not return any values.
I have a valid token and the examples in the documentation work, but if I try any to alter the examples in any way I get nothing back just any empty json object {}.
Example I am trying to use:
https://www.ncdc.noaa.gov/cdo-web/api/v2/data?datasetid=GSOM&stationid=GHCND:US1OHGG0014&units=standard&startdate=2020-08-01&enddate=2020-08-01&limit=1000
Data from the website:
https://www.ncdc.noaa.gov/cdo-web/datasets/GHCND/stations/GHCND:US1OHGG0014/detail

I don't exactly know how you are going to achieve this since you haven't told us what programming language you are using. However, with python I use a module called urllib to extract raw html data from a url that can be seen from the browser using ctrl+u.

Converting CSV to JSON to send POST From React to Flask API

I am attempting to send a POST request to my API from my React app and am figuring out how to change a CSV from input to JSON format so no downloading needs to take place. I have seen people use Papaparse but from what I saw was that it hadn't been updated in a while so I am looking for other options.
const handleSubmit = async (event) => {
event.preventDefault();// from elements property
console.log(event.target.returns.value)
console.log(await axios.post('http://127.0.0.1:5000/ratios', event.target.returns.value))
setShow(true)
};
If I just send like this I get a 500 error and the first line of my POST function on Flask is
df = request.get_json()
maybe there's an easier way but let me know if you have any insight or advice. Thank you in advance
Your question is somewhat confusing and I think it's due to your understanding of how csv and json would interact. CSV is essentially a way to send tables of data, it doesn't have an inherent key pair structure so you need to do a little work to convert it. I'm not familiar with flask specifically but it looks like df = request.get_json() is trying to parse what it expects to be json but is instead csv. You are right that you need to convert that. Papaparse seems like an excellent option and is still under active development. However I don't think that really matters since csv and json are formats that haven't changed in a long time so the task of converting them hasn't changed. So whether or not there has been recent development doesn't matter.
If you decided to roll your own you could probably get close by taking each row and turning that into an object then matching each row entry with a first row key label or just with saved constants. Depend on how your csvs are structured.

How do get the result from REST website that returns only text?

I'm trying to use a REST web service from Geonames.org. When I try to manually put in the url with the parameters, it would only return the Country Code. I've tried to search for ways to implement it, but most of what I've seen return JSON text with multiple keys and data. I feel like the answer should be pretty simple, but I'm unsure.
I'm trying to use this for a React project I'm working on.
Here is an example of what the url returns
Just looked into the docs of that API, and it says if you want to receive JSON responses simply add JSON keyword to the endpoint. Like here for given endpoint you have:
http://api.geonames.org/countryCodeJSON?formatted=true&lat=47.03&lng=10.2&username=demo
so just change countryCode to countryCodeJSON.

Need help parsing through JSON Object in JMETER

I'm testing an application that calls one API, gets a bunch of work orders, then only the work order ID's are passed to another API to display on the page.
The format they need to be in is: {"workOrderIds":["12345","123456"]}
I'm using the JSON Extractor with the following Path Expressions:
$..workOrderNumber
then I'm using the JSR223 PostProcessor and using the following script:
props.put("workOrderNumber", "${workOrderNumber}";
The problem is, that its creating the object like so when I add the variable into the POST Request body of the second request:
{"workOrderIds":["12345, 123456"]}
essentially, I just need to make sure that each value has quotations, but not sure how to make this happen. Sorry if this seems simple, I'm fairly new to QA and have spent several hours trying to figure this out.
We cannot provide a comprehensive answer without seeing the source JSON, maybe it worth trying explicitly casting the filtering result to an Integer like:
vars.put('workOrderIds', new groovy.json.JsonBuilder(new groovy.json.JsonSlurper().parse(prev.getResponseData()).findResults { entry -> entry.workOrderNumber as int }).toPrettyString())

ValueError("No JSON object could be decoded") Python googlemaps

I am using Google app engine (v1.9.24) with flask (v0.10.1) and python (v2.7.5).
I'm trying to get the googlemaps (v2.2) API to work with my app.
I know the JSON returned is badly formatted but I don't why.
My code is below:
import googlemaps
gmaps = googlemaps.Client(key='API_KEY')
geocode_result = gmaps.geocode('6b, oko awo, victoria island, lagos')
return geocode_result
This works perfectly, but returns a badly formatted JSON string (I confirmed this by running the same code on my local machine).
I used JSON validator to validate the JSON it returned. And because of the badly fomatted JSON my flask app crashes and gives me a ValueError.
I don't know a way around this and I'd appreciate any help.
The problem is not with the JSON. Actually,
gmaps.geocode('6b, oko awo, victoria island, lagos')
doesn't return JSON at all, it returns a list that holds the value of "result" as documented in the google docs, as you can see here in the source code for googlemaps library.
What is actually returned is a list object filled with data. All the string values inside this list are unicode strings. That means they look like u'hello' instead of plain "hello" (note the double quotes) that json.loads() expects (I assume that is how you are trying to load the JSON).
This probably means that the problem you're trying to solve a non existing problem. You don't have to load the JSON, because it already is a python list object.
You can confirm by doing
json.loads(json.dumps(geocode_result))
it works fine, meaning there is no problem with the JSON structure.

Getting $http.put() to send correctly formatted data, instead of JSON object

So, I spent some time and built a quick API for a project that I'm doing for myself.
I used the Postman add-on for Chrome to mimic PUT and DELETE quests to make sure everything worked correctly. Really happy I did that, as I learned a lot about PHP's shortcomings with PUT and DELETE requests.
Using the API I've had working with Postman, I started moving everything over to AngularJs controllers and such.
I'm trying to get a user to claim a row in a database as the login information for the users is different than this particular information. I couldn't figure out why the put requests to claim the row in my database wasn't working. Lo and behold, the data being parsed from my parsestr(file_get_contents('php://input')) had 1 array key, which was a JSON string.
I've looked, and I can't seem to find a solid answer either through Stackoverflow or Google (maybe I missed it somewhere in the config options), So my question is this: is there any way I can get the $http.put call send the data to the server correctly?
Thanks to user Chandermani for pointing me to the link at this URL which answered the base of my question.
From the above link, I found myself on This Blog post submitted by another user. In the end, what I ended up doing was the following:
taking param() function from the above link, as well as implementing these lines of code:
var app = angular.module('ucpData', [] , function($httpProvider){
$httpProvider.defaults.transformRequest = [function(data) {
return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
}];
});
Is how I worked around the problem. For some developers, you may actually want to keep the default transformRequest settings, but for the project I am doing I know that I will end up forgetting to call param() at some point, and my server doesn't naturally accept json data anyway. I would caution future developers to consider what they are attempting to do before they alter the transformRequest array directly.
