API connection error

Question

I cannot believe an API call is giving me errors lol

I really don't know what happening.

I tested to if my Api call was ok, and it is ok

I get 200 status code OK

When I put it in Maui strange things happen

Windows

Android

for Android I made sure to modify the manifest

	<application android:allowBackup="true" android:icon="@mipmap/appicon" android:supportsRtl="true" android:usesCleartextTraffic="true">
		<meta-data android:name="com.google.android.geo.API_KEY" android:value="xxxxx" />
		<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
		
	</application>
	<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
	<uses-permission android:name="android.permission.INTERNET" />
	<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
	<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

My httpServce

    public class HttpService(HttpClient httpClient, IConnectivity connectivity) {
        public async Task<T?> GetAsync<T>(string url) {
            if (connectivity.NetworkAccess != NetworkAccess.Internet) {
                await Shell.Current.DisplayAlert("Error",
                    "No internet connectivity"
                    , "OK");
                return default;
            }
            try {
                var response =
                    await httpClient.GetAsync(url);
                if (response.IsSuccessStatusCode) {
                    var jsonData = await response.Content.ReadAsStringAsync();
                    Console.WriteLine("Received JSON: " + jsonData); // Debugging line
                    var data = await response.Content.ReadFromJsonAsync<T>();
                    return data;
                } else {
                    Console.WriteLine($"Request failed with status code: {response.StatusCode}");
                    await Shell.Current.DisplayAlert("HTTP Error", $"Status code: {response.StatusCode}", "OK");
                }
            } catch (HttpRequestException httpEx) {
                await Shell.Current.DisplayAlert("HTTP Error", httpEx.Message, "OK");
                Console.WriteLine("Request URL: " + url); // Debugging line
            } catch (JsonException jsonEx) {
                await Shell.Current.DisplayAlert("JSON Error", jsonEx.Message, "OK");
            } catch (Exception ex) {
                await Shell.Current.DisplayAlert("Unknown error", ex.Message, "OK");
            }
            return default;
        }
    }
}

viewModel

        private readonly HttpService httpService;

        private ObservableCollection<EnergyNews> NewsList {  get; set; }

        public HomePageViewModel(HttpService httpService) {

            this.httpService = httpService;
            LoadNews();
        }

        private async void LoadNews() {

            var h = await httpService.GetAsync<object>("https://newsapi.org/v2/everything?q=renewable+energy&apiKey=5963dd2ef5ff48b9bfa99e902bd55716");
        }

    }
}

Note: I am living my Api key here, so you can test and see that everything is ok, because this is the first time this happens to me

Hello,

You can get result correctly by adding HttpClient.DefaultRequestHeaders Property in the HttpClient.

Then you can get the data like a web Brower.

You can refer to the following code.

 httpClient.DefaultRequestHeaders.Add("User-Agent", "Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Googlebot/2.1; +http://www.google.com/bot.html)");

 var response =
     await httpClient.GetAsync(url);

Best Regards,

Leon Lu
