如何为SOCRATA休息呼叫处理太大的requestUri？

Question

我正在使用RESTful调用socrata数据门户来获取数据。

HttpClient client = new HttpClient();            
client.BaseAddress = new Uri(WebConfigurationManager.AppSettings["APIEndPointHost"]);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
string userName = WebConfigurationManager.AppSettings["UserName"];
string password = WebConfigurationManager.AppSettings["PassWord"];
string credentials = userName + ":" + password;
var byteArray = Encoding.ASCII.GetBytes(credentials);
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));
client.DefaultRequestHeaders.Add("X-App-Token", WebConfigurationManager.AppSettings["AppToken"]);

 HttpResponseMessage response = new HttpResponseMessage();
string searchCondition = "resource/xxxx-xxxx.json?$where=column1='something'AND column2='something';
 response = client.GetAsync(searchCondition).Result;

问题在于，有时候＆＃39; searchCondition＆＃39;可以说非常大，超过5000个字符，然后在执行时会出现以下错误。

  

发送请求时发生错误。

     

服务器提交了协议违规。节= ResponseStatusLine

这是因为我发送了一个大的requestUri，还是这与socrata限制搜索条件限制有关？
