fetch("https://public-api.solscan.io/transaction/"+JSON.parse(message.data).params.result.value.signature)
.then(response => response.json())
.then(response => console.log(JSON.stringify(response.parsedInstruction[1].params.mint)))
.catch(error => nothing());
but i need
JSON.stringify(response.parsedInstruction[1].params.mint
in a variable so i can make another api request please help me
this is the code where i want to use with the variable
const mintAddress = new PublicKey("7brV5ykCzriKhVhj99kav97LQQrpb18J3kMonGxveML2");

I am using React\NextJS as forntend and Laravel as backend,
Storing data with Axios post as per below,
const storeExpense = async (expenseData) => {
const response = await axios.post('/api/expenses/store/', {expenseData})
return response.data;
}
Now this will be sent as a JSON object to Laravel, I am not sure how can I validate and store this JSON object data to MySQL.
Earlier I was using Jquery AJAX where it was easy to store with Request validation and then with create.
Below is the request payload to the backend,
{"expenseData":{"expense_description":"React","expense_date":"2022-17-4","expense_amount":"123","expense_tax_amount":"14.15","expense_note":"given","expense_receipt_number":"Ok no","taxgroup_id":1,"paymentoption_id":1,"vendor_id":1,"accountcustomtype_id":2,"submit":null}}
Below was Controller and Model, used when sending data as Form
//Controller
public function store(StoreExpenseRequest $request)
{
Expense::storeExpense($request);
return response()->json([
'val' => 1,
'msg' => 'Success',
]);
}
//Model
public static function storeExpense($request)
{
Expense::create([
'vendor_id' => $request->vendor_id,
'accountcustomtype_id' => $request->accountcustomtype_id,
'expense_description' => $request->expense_description,
'expense_date' => Carbon::parse($request->expense_date)->format('Y-m-d'),
'expense_amount' => $request->expense_amount,
'taxgroup_id' => $request->taxgroup_id,
'expense_tax_amount' => $request->expense_tax_amount,
'paymentoption_id' => $request->paymentoption_id,
'expense_receipt_number' => $request->expense_receipt_number,
'expense_note' => $request->expense_note,
]);
}
But now this doesn't work with JSON data,
How can I achieve this with Axios JSON data?
Thank you,
It was resolved by changing Axios request Data,
await axios.post('/api/expenses/store/', expenseData)
componentDidMount() {
fetch("http://localhost:5000/customers/:id")
.then((res) => res.json())
.then((info) => {
this.setState({ info });
})
.then((err) => console.log(err));
}
How to fetch a specific data from database by sending the required ID with URL?
You can use the format string syntax from javascript and add the id to the url-string with that.
const id = 42
fetch(`http://localhost:5000/customers/${id}`)
I'm not able to pick out a certain key/value from a fetched JSON file, and then assign it to a variable.
const fetch = require("node-fetch");
var url = 'https://randomuser.me/api/'
fetch(url)
.then((response) => response.json())
.then((hmm) => console.log(hmm.results))
The above code serves to return info from the top branch, "results", but I can't get any deeper.
Modifying it to .then((hmm) => console.log(hmm.results.gender)) returns undefined.
I'd then like to assign the Value from the "gender" Key to a variable.
results is an array.
You need to do results[0].gender
.then((hmm) => console.log(hmm.results[0].gender))
const fetch = require("node-fetch");
var url = 'https://randomuser.me/api/'
fetch(url)
.then((response) => response.json())
.then(function (hmm) {
var data = hmm.results[0].gender;
console.log(data)
})
What's wrong with this picture ? :-)
I'm trying to pull values from my wordpress JSON objects.
I must not be addressing them the correct/proper way with React-Native.
Can someone direct me as to how to form the correct console log statement ?
As it stands right now, the variable 'theMediaLink' is coming up 'undefined' in the console log. :-(
state={
data:[]
}
fetchData = async() => {
const response = await
//response
fetch('http://example.com/wp-json/wp/v2/posts/')
//posts
const posts = await response.json();
this.setState({data:posts});
const theMediaLink = `https://example.com/wp-json/wp/v2/media/` + `${this.state.data.featuredmedia}`;
console.log('theMediaLink_value: ', theMediaLink);
}
I should add that the fetch is retrieving data as I use it later on with a FLATLIST to pull the posts. My question is I must be misforming the call, but how ?
This is more an issue of understanding of React rather than React Native.
Try this:
fetchData = async () => {
const URL = 'http://example.com/wp-json/wp/v2/posts/'
const response = await fetch(URL)
const posts = await response.json();
return this.setState({ data : posts }, () => {
const { data } = this.state
const theMediaLink = `https://example.com/wp-json/wp/v2/media/${ data.featuredmedia }`;
console.log('theMediaLink_value: ', theMediaLink);
});
}
Since setState is asynchronous, you won't be able to see the state update right away, that's why the callback is for.

Is there any way to determine if a Axios request like the following received an answer and is done?
axios.get('/api')
.then(response => this.data = response.data);
Yes, this is a promise and you can reference and then it:
var req = axios.get('/api')
.then(response => this.data = response.data);
Now I want to react to it being done:
req.then(x => console.log("Done!"));
Or save that state outside:
var isReqDone = false;
req.then(x => isReqDone = true);
