几个错误的思考，不知道是否正确。 public static async Task<HttpResponse<T>> HttpPostTaskAsync<T>(string url, object q){try{StringContent content = new StringContent(JsonConvert.SerializeObject(q, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore }));content.Headers.ContentType = new MediaTypeHeaderValue("application/json");var ret = await _HC.PostAsync(url, content);if (!ret...
我正在使用TestServer测试ASP.NET Core应用,并且有些控制器需要Cookie身份验证.我已经创建了这样的测试服务器实例：_testServer = new TestServer(new WebHostBuilder().UseEnvironment(CustomEnvironments.Test).UseContentRoot(currentDirectory) .UseStartup<Web.Startup>().UseUrls("http://localhost/"));ApiClient = _testServer.CreateClient();现在我必须添加身份验证Cookie,但服务器会忽略它.如果可以直接...
三者的区别 HttpWebRequest 命名空间： System.Net，这是.NET创建者最初开发用于使用HTTP请求的标准类。使用HttpWebRequest可以让开发者控制请求/响应流程的各个方面，如 timeouts, cookies, headers, protocols。另一个好处是HttpWebRequest类不会阻塞UI线程。例如，当您从响应很慢的API服务器下载大文件时，您的应用程序的UI不会停止响应。HttpWebRequest通常和WebResponse一起使用，一个发送请求，一个获取数据。HttpWebRquest更...

导读: 仅供使用httpclient库模拟http请求,Post请求头 Content-Type:?application/x-www-form-urlencoded 遇到?非字母或数字的字符 时转义的问题 直接上code:https://github.com/dswyzx/forblogs及结果截图 1:问题:因对接接口,参数内存在字符"+",导致双方对参数进行确认时发生分歧 具体表现为:"+"字符在httpclient 为HttpRequestMessage 请求体封装HttpRequestMessage.Content时,全部参数默认被打包为byte数组,并没有像浏览器默认操...

在我正在使用的ASP.Net MVC 4 Web应用程序中.我有一页基本上通过从SOAP服务获取数据来生成报告. 我的代码基本上是这样的List<CustomThings> serverInfos = ServerInfos; serverInfos.AsParallel().ForAll(srvInfo => {SoapHttpClientProtocol soapProxy = CreateProxy(srvInfo);//call make soap calls through the soap client//store results in the proper places }我在这里做AsParallel的原因是因为以串行方式通过HTTP进行多个...
我在使用HTTPClient的C#中具有以下代码,并且尝试迁移到RestSharp以利用漂亮的反序列化代码 这是我当前的代码：var httpClient = new HttpClient(new HttpClientHandler(){UseDefaultCredentials = true,AllowAutoRedirect = false});var response = httpClient.GetStringAsync(myUrl).Result;这是使用restsharp的等效代码：_client = new RestClient { BaseUrl =new Uri(myUrl) };var request = new RestRequest { Method = method...
我们看到一个问题,即客户点击我们的API并在请求完成之前取消了该请求.我们相信他们也正在关闭连接,因此请求不会被写入IIS日志.我正在尝试创建一个跑步者来复制此行为.我不知道如何强制关闭连接,以使服务器无法将数据发送回去？ 这是我当前的代码：private static async Task RunMe(){var cts = new CancellationTokenSource();cts.CancelAfter(5000);using (var client = new HttpClient()){try{client.DefaultRequestHeaders.Conn...
现在的情况 有一个客户端通过HttpClient.GetAsync执行get请求.不幸的是,由于某种原因,我们需要阻止该调用. 为此,使用此Asynchelper类以避免上下文切换死锁(而不是仅使用.Result).public static class AsyncHelper{private static readonly TaskFactory _myTaskFactory = newTaskFactory(CancellationToken.None,TaskCreationOptions.None,TaskContinuationOptions.None,TaskScheduler.Default);public static void RunSync(Func<Ta...
