我正在通过.NET的HttpClient调用一个服务错误,尝试通过本地代理(Fiddler)路由请求,但我的代理设置似乎没有生效.

这是我创建客户端的方式:

private HttpClient CreateHttpClient(CommandContext ctx, string sid) {
    var cookies = new CookieContainer();

    var handler = new HttpClientHandler {
        CookieContainer = cookies,
        UseCookies = true,
        UseDefaultCredentials = false,
        Proxy = new WebProxy("http://localhost:8888", false, new string[]{}),
        UseProxy = true,
    };

    // snip out some irrelevant setting of authentication cookies

    var client = new HttpClient(handler) {
        BaseAddress = _prefServerBaseUrl,
    };

    client.DefaultRequestHeaders.Accept.Add(
        new MediaTypeWithQualityHeaderValue("application/json"));

    return client;
}

然后我通过以下方式发送请求:

var response = CreateHttpClient(ctx, sid).PostAsJsonAsync("api/prefs/", smp).Result;

请求直接进入服务器而不尝试命中代理.我错过了什么？
