不知什么时候 ，出现了这样的一个奇怪问题，简单的httpClient.GetAsync("xxxx")居然报错了。...一、问题描述 把原来的程序从2.0升级到2.1，突然发现原本正常运行的httpClient.GetAsync("xxxx")居然不工作了。...为了排除项目中其他引用的干扰，新建了一个干净的2.1的项目，Main里直接调用 var client = new HttpClient(); var task = client.GetAsync(url

GetAsync(string key) { return await _permissionStore.GetByKeyAsync(key); } 这样在 RolePermissionManager...AddRolePermission(TRole role, string permissionKey) { var permission = await _permissionManager.GetAsync...InvalidOperationException($"Role not found:{roleId}"); } var permission = await _permissionManager.GetAsync

如果请求成功 // */ //} var result2 = await httpClient.GetAsync...// httpclient 已经携带 Cookie ，可以多次使用 // var result3 = await httpClient.GetAsync...(url3); // var result4 = await httpClient.GetAsync(url4); httpClient.Dispose...对于 GetAsync、PostAsync等请求方法，使用过程类似，下面是使用示例 public async void Request(string url) {...(url); // Task.Result 可以获取异步结果 result = httpClient.GetAsync(url).Result

cts.CancelAfter(3000); HttpClient client = new HttpClient(); var res = await client.GetAsync...client.Dispose(); } 在上面的代码中，首先定义了一个 CancellationTokenSource 对象，然后马上发起了一个 HttpClient 的 GetAsync...请求（注意，这种使用 HttpClient 的方式是不正确的，详见我的博客 HttpClient的演进和避坑 ；在 GetAsync 请求中传入了一个取消令牌，然后立即发起了退出请求 Console.WriteLine...; Console.WriteLine("cts1:{0}", result); var res2 = await new HttpClient().GetAsync...Console.WriteLine("cts2:{0}", result2); var res3 = await new HttpClient().GetAsync
using (var client = new FlurlClient()) { var response = client.GetAsync...using (var client = new FlurlClient()) { var response = client.GetAsync
示例代码： using (HttpClient client = new HttpClient()) { HttpResponseMessage response = await client.GetAsync...response.Content.ReadAsStringAsync(); Console.WriteLine(responseBody); } 在上面的示例中，我们首先创建了一个HttpClient实例，并使用GetAsync...httpClient = _httpClientFactory.CreateClient(); HttpResponseMessage response = await httpClient.GetAsync...httpClientFactory.CreateClient("ExampleClient"); HttpResponseMessage response = await httpClient.GetAsync...public async Task GetData() { HttpResponseMessage response = await _httpClient.GetAsync
将其下载下来，代码如下 var httpClient = new HttpClient(); using var httpResponseMessage = await httpClient.GetAsync...以上代码的另一个细节是请求的时候带上了 HttpCompletionOption.ResponseHeadersRead 参数，带上这个参数将告诉 HttpClient 不要等待内容都拉取完了再让 GetAsync...这一点对下载文件来说，比较有优化，大部分下载的文件的文件长度都不小，全等待下载完成再让 GetAsync 返回，再拷贝到文件，这个逻辑相对来说是比较亏的。...ToUpperInvariant() + age.ToString())}/{pdbName}"; using var httpResponseMessage = await httpClient.GetAsync
