I'm getting 403 with HttpClient on Portable Class Library

c#, portable-class-library, web-services, windows-8, windows-phone

Solution

It seems you need credentials and to point at the api instead , that's why its "Forbiden"

Try calling it like a browser : from this other question "HttpClient Request like browser"

void Main()
{

    GetIP("http://www.ip-adress.com/");

}

async void GetIP(string url){
    try{
    "Looking Up".Dump("OK");
    var x = await  GetResponse(url);
    x.Dump();
    }
    catch(Exception e){
        e.Dump("Problems:");
    }
}

private static async Task<string> GetResponse(string url)
{
    var httpClient = new HttpClient();

    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "text/html,application/xhtml+xml,application/xml");
    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Accept-Encoding", "gzip, deflate");
    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("User-Agent", "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0");
    httpClient.DefaultRequestHeaders.TryAddWithoutValidation("Accept-Charset", "ISO-8859-1");

    var response = await httpClient.GetAsync(new Uri(url));

    response.EnsureSuccessStatusCode();
    using (var responseStream = await response.Content.ReadAsStreamAsync())
    //using (var decompressedStream = new System.IO.Compression.GZipStream(responseStream, CompressionMode.Decompress))
    using (var streamReader = new StreamReader(responseStream))
    {
        return streamReader.ReadToEnd();
    }
}

//Note :I commented out the compression,

Problem

I have a PCL, WP and WinStore projects. In the PCL project I have a class with this method: ``` private async Task<string> GetIpAddress() { const string url = "http://www.ip-adress.com/"; const string buscar = "<h3>Your IP address is:"; var client = new HttpClient(); var data = await client.GetStringAsync(url); if (data.IndexOf(buscar, StringComparison.Ordinal) <= -1) return; var IpAddress = data.Remove(0, data.IndexOf(buscar, StringComparison.Ordinal) + buscar.Length + 1); IpAddress = IpAddress.Remove(IpAddress.IndexOf("</h3>", StringComparison.Ordinal)); return IpAddress; } ``` When I invoke the method on the Windows Phone project works perfectly, but not in the Windows Store project. Instead, I'm getting this error message:
