我在发出Http请求时收到System.Threading.Tasks.TaskCanceledException
。
public async Task<CommonResult<T>> GetRequest<T>(TokenModel token, string url)
{
using (var client = new HttpClient())
{
client.MaxResponseContentBufferSize = int.MaxValue;
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(token.TokenType, token.AccessToken);
var response = await client.GetAsync(url);
if (response.IsSuccessStatusCode)
{
return await OK<T>(response);
}
else
{
//The response is authorized but some other error.
if (IsAuthorized(response.StatusCode))
return Error<T>(response.StatusCode.ToString());
//Unable to refresh token.
if (!await RenewToken(token))
return Error<T>("Fail to refresh token");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(GlobalData.Token.TokenType, GlobalData.Token.AccessToken);
response = await client.GetAsync(url);
if (response.IsSuccessStatusCode)
{
return await OK<T>(response);
}
else
{
return Error<T>(response.StatusCode.ToString());
}
}
}
}
当我调试服务器代码而不是继续时,会发生这种情况。这是自然行为还是我在客户端代码中遗漏了什么?
答案 0 :(得分:4)
这是预期的行为,默认情况下HttpClient
设置timeout of 100 seconds。
HttpClient超时
您可以调整HttpClient
并设置自定义超时持续时间。例如,您可以设置InfiniteTimeSpan
以防止发生超时。
client.Timeout = Timeout.InfiniteTimeSpan;
HttpClient请求超时
您还可以使用CancellationTokenSource
为每个请求定义超时using (var cts = new CancellationTokenSource(Timeout.InfiniteTimeSpan))
{
await client.GetAsync(url, cts.Token).ConfigureAwait(false);
}
