在本地很够正常执行，发布到服务器上就不行，于是我打印日志发现错误信息是:The SSL connection could not be established, see inner exception.

好像是SLL连接被拒绝了，检查代码发现我是请求了接口的，源码如下

 public RESTResponseEntity RequestGet(string url)
        {
            RESTResponseEntity entity = new RESTResponseEntity();
            try
            {
               
                HttpClient httpClient = new HttpClient();
                if (timeout > 0)
                {
                    httpClient.Timeout = TimeSpan.FromMilliseconds(timeout);
                }
                //httpClient.DefaultRequestHeaders.Add(HEAD_KEY, TOKEN_KEY_PREFIX + " " + tokenKey);
                string strUrl = baseUrl + url;
                HttpResponseMessage hrm = httpClient.GetAsync(strUrl).Result;
                entity.StatusCode = Convert.ToInt32(hrm.StatusCode);
                entity.Data = hrm.Content.ReadAsStringAsync();
            }
            catch (Exception ex)
            {
                throw;
            }
            return entity;
        }

后面查阅后，加如下代码可解决这个问题，改造后

 public RESTResponseEntity RequestGet(string url)
        {
            RESTResponseEntity entity = new RESTResponseEntity();
            try
            {
                var httpClientHandler = new HttpClientHandler
                {
                    ServerCertificateCustomValidationCallback = (message, certificate2, arg3, arg4) => true
                };
                HttpClient httpClient = new HttpClient(httpClientHandler);
                if (timeout > 0)
                {
                    httpClient.Timeout = TimeSpan.FromMilliseconds(timeout);
                }
                //httpClient.DefaultRequestHeaders.Add(HEAD_KEY, TOKEN_KEY_PREFIX + " " + tokenKey);
                string strUrl = baseUrl + url;
                HttpResponseMessage hrm = httpClient.GetAsync(strUrl).Result;
                entity.StatusCode = Convert.ToInt32(hrm.StatusCode);
                entity.Data = hrm.Content.ReadAsStringAsync();
            }
            catch (Exception ex)
            {
                throw;
            }
            return entity;
        }
