When I try to make a simple POST request from my VueJS application to the Twilio API for sending an SMS, I encounter an error message:
"Access to XMLHttpRequest at 'https://api.twilio.com/2010-04-01/Accounts/AC42exxxxxxxxxxcfa9c48/SMS/Messages' from origin 'http://localhost:8080' has been blocked by CORS policy: Request header field username is not allowed by Access-Control-Allow-Headers in preflight response."The code causing this error is as follows:
sendTwilio(){
const accountSid = process.env.TWILIO_ACCOUNT_SID;
const authToken = process.env.TWILIO_AUTH_TOKEN;
const sFromNumber = process.env.TWILIO_NUMBER;
const sBaseURL = 'https://api.twilio.com';
const phoneNumber = parsePhoneNumberFromString(this.sms.to_number,'US')
const headers = {
'Content-Type': 'application/json',
'Authorization': `Bearer ${authToken}`,
'username': `${accountSid}`
},
sBodyText='Test'
this.SmsUrl = sBaseURL + '/2010-04-01/Accounts/' + accountSid + '/SMS/Messages';
if (phoneNumber.isValid()){
this.sms.formattedPhone = phoneNumber.number;
this.postData = 'From=' + sFromNumber
+ '+To=' + phoneNumber.number
+ '+Body=' + sBodyText
axios.post(`${this.SmsUrl}`, this.postData, {
headers: headers
})
.then((response) => {
console.log(response)
})
.catch((error) => {
console.log(error)
})
}
},
Do you think the issue lies with the username format in the header or could it be related to my CORS settings?
This is how my CORS settings are configured:
CORS_ORIGIN_ALLOW_ALL = True
CORS_ORIGIN_WHITELIST = [
'http://localhost:8000',
'http://localhost:8080',
'http://127.0.0.1:8000'
]
