So I am making a request to an API endpoint. When I print JSONBody which is the variable data passed to POSTRequest(), I get the JSON I created printed to the log, however when I then try and JSON.Stringify() it, I get returned an empty object?
Was just wondering what I am doing wrong and how to fix it :)
getFileData()
const getFileData = () => {
var data = {}
// DO SOME STUFF HERE TO data
POSTRequest(data);
}
POSTRequest()
const POSTRequest = async (JSONBody) => {
console.log(JSONBody)
console.log(JSON.stringify(JSONBody))
try {
const response = await fetch(API_ENDPOINT, {
method: 'POST',
body: JSON.stringify(JSONBody),
headers: { 'Content-Type': 'application/json' }
});
response.json()
.then(function (res) {
Promise.resolve(res)
.then(function (finalData) {
console.log(finalData);
props.setData(finalData);
});
});
} catch (error) {
console.log(error);
}
}
You're not waiting for the response from the fetch call correctly, try this:
const POSTRequest = async (JSONBody) => {
console.log(JSONBody)
console.log(JSON.stringify(JSONBody))
await fetch(API_ENDPOINT, {
method: 'POST',
body: JSON.stringify(JSONBody),
headers: { 'Content-Type': 'application/json' }
}).then((response) => {
console.log(response);
props.setData(response);
}).catch((error) => {
console.log('POSTRequest error: ' + error)
})
});
