Question

I am attempting to utilize the SkyScanner API from RapidAPI with Angular to find flight cost information. Below is my current implementation:

let requestHeaders = new Headers();
let flightApiUrl: string;

constructor(private httpClient: HttpClient) {
    this.requestHeaders.append('X-RapidAPI-Key', 'MY-KEY');
    this.flightApiUrl = 'https://skyscanner-skyscanner-flight-search-v1.p.rapidapi.com/apiservices/browseroutes/v1.0/IE/EUR/en-GB/{other-parameters-should-go-here}';
}

I am sending values for from, to, day, month, and year through user inputs:

retrieveFlightInfo(departure: string, arrival: string, travelDay: number, travelMonth: number, travelYear: number): Observable<IFlightDetails> {
    return this.httpClient.get<IFlightDetails>(this.flightApiUrl + this.requestHeaders)
    .pipe(
        tap(response => console.log('flightInfo/error: ' + JSON.stringify(response))),
        catchError(this.handleError)
    );
}

However, when I attempt to run the application, I encounter the following error:

401 Unauthorized

Try setting the headers correctly and include them in your HTTP request:

retrieveFlightInfo(departure: string, arrival: string, travelDay: number, travelMonth: number, travelYear: number): Observable { const headers = new HttpHeaders().set('X-RapidAPI-Key', 'MY-KEY'); const url = `${this.flightApiUrl.replace('{other-parameters-should-go-here}', `${departure}/${arrival}/${travelYear}-${travelMonth}-${travelDay}`)}`; 
return this.httpClient.get<IFlightDetails>(url, { headers })
.pipe(
    tap(response => console.log('flightInfo:', response)),
    catchError(this.handleError)
);

}

Ensure MY-KEY is correct and the URL is properly constructed with the necessary query parameters.

To resolve the 401 Unauthorized error while using the SkyScanner API with Angular, ensure your API key is correctly set and headers are properly configured. Here's a way to optimize your function:

import { HttpHeaders, HttpClient } from '@angular/common/http'; import { Observable } from 'rxjs'; import { catchError, tap } from 'rxjs/operators';

retrieveFlightInfo(departure: string, arrival: string, travelDay: number, travelMonth: number, travelYear: number): Observable {
const headers = new HttpHeaders({ ‘X-RapidAPI-Key’: ‘MY-KEY’ });
const url = this.flightApiUrl.replace(‘{other-parameters-should-go-here}’, ${departure}/${arrival}/${travelYear}-${travelMonth}-${travelDay});

return this.httpClient.get<IFlightDetails>(url, { headers })
.pipe(
    tap(response => console.log('flightInfo:', response)),
    catchError(this.handleError)
);

}

Steps to ensure this works:

  • Verify MY-KEY is your actual RapidAPI key.
  • Ensure the URL is built correctly with appropriate parameters like departure, arrival, and formatted date.
  • Use proper error handling to diagnose any other HTTP issues.

These adjustments should help eliminate the unauthorized error and improve system efficiency.

To address the 401 Unauthorized error you are experiencing while integrating the SkyScanner API via RapidAPI with Angular, ensure your configuration includes accurate authentication details. One reason for this error could be incorrect placement or usage of the API key in your request. You also need to ensure that the URL is correctly formatted with appropriate values.

Here is an improved method to handle this integration:

import { HttpClient, HttpHeaders } from '@angular/common/http'; import { Observable } from 'rxjs'; import { catchError, tap } from 'rxjs/operators';

retrieveFlightInfo(departure: string, arrival: string, travelDay: number, travelMonth: number, travelYear: number): Observable<IFlightDetails> {
const headers = new HttpHeaders({ ‘X-RapidAPI-Key’: ‘YOUR-VALID-KEY’ });
const formattedUrl = this.flightApiUrl.replace(‘{other-parameters-should-go-here}’, ${departure}/${arrival}/${travelYear}-${travelMonth}-${travelDay});

return this.httpClient.get&lt;IFlightDetails&gt;(formattedUrl, { headers })
.pipe(
    tap(response => console.log('Flight information:', response)),
    catchError(error => { 
        console.error('Error fetching flight info:', error);
        return this.handleError(error);
    })
);

}

Consider the following points to ensure the function works smoothly:

  • Double-check that YOUR-VALID-KEY is your actual API key for RapidAPI. This is necessary for authentication.
  • Carefully format the endpoint URL by replacing the placeholder with appropriate parameters (e.g., departure, arrival, and date information).
  • Incorporate comprehensive error handling to effectively diagnose any arising issues and log them appropriately.

Following these refined steps should help mitigate the 401 Unauthorized error and promote a more successful API request execution.

To overcome the 401 Unauthorized issue with the SkyScanner API, ensure your API key configuration is correct and headers are properly set. Modify your function as follows:

import { HttpClient, HttpHeaders } from '@angular/common/http'; import { Observable } from 'rxjs'; import { catchError, tap } from 'rxjs/operators';

retrieveFlightInfo(departure: string, arrival: string, travelDay: number, travelMonth: number, travelYear: number): Observable<IFlightDetails> {
const headers = new HttpHeaders({ ‘X-RapidAPI-Key’: ‘YOUR-API-KEY’ });
const formattedUrl = this.flightApiUrl.replace(‘{other-parameters-should-go-here}’, ${departure}/${arrival}/${travelYear}-${travelMonth}-${travelDay});

return this.httpClient.get&lt;IFlightDetails&gt;(formattedUrl, { headers })
.pipe(
    tap(response => console.log('Flight info:', response)),
    catchError(this.handleError)
);

}

Ensure:

  • YOUR-API-KEY is replaced with your actual RapidAPI key.
  • The URL is replaced correctly with departure, arrival, and formatted date.
