c# - “UTF8”不是受支持的编码名称

Question

所以我只是在玩弄 Spotify 的 Web API，我正在尝试访问我最常播放的轨道。尽管我遇到了几个小时以来一直试图解决的问题，但我找不到答案。

当我尝试反序列化我的响应时，出现以下错误:

'UTF8' is not a supported encoding name. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method. Parameter name: name The character set provided in ContentType is invalid. Cannot read content as string using an invalid character set.

内容类型是application/json；字符集=UTF8

有什么想法吗？

这是我的请求代码:

private static HttpClient GetHttpClient()
{
    HttpClientHandler handler = new HttpClientHandler() {
        AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
    };
    var httpClient = new HttpClient(handler);
    httpClient.DefaultRequestHeaders.Add("Accept", "application/json");
    return httpClient;
}

public async Task<SearchArtistResponse> GetSelfTopAsync(string type, string userName)
{
    var httpClient = GetHttpClient();
    httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", GetAccessToken(userName));

    var sb = new StringBuilder();
    sb.Append(ApiUrl);
    sb.Append($"/me/top/{type}");
    var query = sb.ToString();
    var response = await httpClient.GetAsync(query);

    var spotifyResponse = JsonConvert.DeserializeObject<SearchArtistResponse>(await response.Content.ReadAsStringAsync());
    return spotifyResponse;
}

您使用的是 .net 核心吗？

您将需要添加以下代码以使 .NET 桌面中的编码在您的环境中可用:

System.Text.EncodingProvider provider = System.Text.CodePagesEncodingProvider.Instance;
Encoding.RegisterProvider(provider);
