Postman中Basic Auth验证

也可以直接在Headers中新增一个Key: Authorization, Value: Basic xxxx：

如下图所示：

同理：如果是JWT Token验证，写法为：

request.AddHeader("Authorization", "Bearer " + token.AccessToken);

Basic 后面为user:password形式的Base64加密字符串，中间有一个空格：

Base64加密：

var plainTextBytes = Encoding.UTF8.GetBytes("admin:1234");
            string baseResult= System.Convert.ToBase64String(plainTextBytes);

Base64解码：

var base64EncodedBytes = System.Convert.FromBase64String("YWRtaW46MTIzNA==");
            string test = System.Text.Encoding.UTF8.GetString(base64EncodedBytes);

C# .net core后台请求接口：

 string url = "http://127.0.0.1:8080/api/v5/clients/mqttx_c47a6ca6";
using HttpRequestMessage reqMsg = new HttpRequestMessage(HttpMethod.Get,url);
reqMsg.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
reqMsg.Headers.Authorization = new AuthenticationHeaderValue("Basic", "YWRtaW46MTIzNA==");

HttpResponseMessage responseMessage = await httpClient.SendAsync(reqMsg);
if (responseMessage.IsSuccessStatusCode)
{
   string json =await responseMessage.Content.ReadAsStringAsync();
   JObject obj = JObject.Parse(json);
   JToken token = obj.SelectToken("$.data");
}
