响应总是空的，但是当通过curl调用API时，返回主体内容。

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("https://localhost:5008/Accounts/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "ACCESSTOKENHERE");

    //GET Method  
    HttpResponseMessage httpResponse = await client.GetAsync("searchKeyword=" + searchKeyword);

    try
    {
        AccountListResponse response = await httpResponse.Content.ReadAsAsync<AccountListResponse>();
    }
    catch (Exception)
    {
    }

}
