當(dāng)從 HTTP 管理器調(diào)用請(qǐng)求時(shí)，應(yīng)用程序會(huì)拋出 NSURL 錯(cuò)誤，表明互聯(lián)網(wǎng)連接已離線。Foundation.NSErrorException: Error Domain=NSURLErrorDomain Code=-1009 "The Internet connection appears to be offline."這種情況僅有時(shí)發(fā)生，每次發(fā)生時(shí)設(shè)備都可以訪問(wèn)互聯(lián)網(wǎng)。在嘗試調(diào)試解決方案時(shí)，似乎其余服務(wù)調(diào)用client.GetAsync沒有返回響應(yīng)。public async Task<T> callGetAsync<T>(string path) {    using(var client = new HttpClient()) {        var result = default(T);        client.BaseAddress = new Uri(url);        client.DefaultRequestHeaders.Accept.Clear();        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));        if (App.User.Context != null)        {            client.DefaultRequestHeaders.Authorization =            new AuthenticationHeaderValue("Bearer", App.User.Context.AccessToken);        }        HttpResponseMessage response = await client.GetAsync(path);        if(response.IsSuccessStatusCode) {            string json = await response.Content.ReadAsStringAsync();            result = JsonConvert.DeserializeObject<T>(json);        }        else {            Console.WriteLine("Error");            Analytics.TrackEvent($"API Failure: {path}");        }        return result;    }}預(yù)期結(jié)果是應(yīng)用程序應(yīng)成功撥打電話并返回所需結(jié)果，而不是應(yīng)用程序建議互聯(lián)網(wǎng)連接已離線。還有其他人看到過(guò)這種行為嗎？如果是這樣，你能解決它嗎？
