做内部接口转发时加token验证需要传token值过去，有如下两种方式：
代码语言：c#复制 string jsonContent = JsonConvert.SerializeObject(args);
using(var clientUrl = new HttpClient())
{
var token = "token的值";
// 法①
clientUrl.DefaultRequestHeaders.Add("token", token);
var data = new StringContent(jsonContent, Encoding.UTF8, "application/json");
result = clientUrl.PostAsync(url, data).Result.Content.ReadAsStringAsync().Result;
// 法②
var data = new StringContent(jsonContent, Encoding.UTF8, "application/json");
data.Headers.Add("token", token);
result = clientUrl.PostAsync(url, data).Result.Content.ReadAsStringAsync().Result;
}
