catch(Exception ex)

throw;
}
}
这是拼接Post请求参数
public string getPostStr(string op, string ac, string json)
{
//var jObject = JObject.Parse(json);
string jsonStr = "op=" + op + "&action=" + ac + "&Login_type=chain&data=" + json+"&";
return jsonStr;
}
JSONHelper jsonHelper = new JSONHelper();
string postStr = "";//post 参数
string jsonStr = jsonHelper.getPostStr("", "", postStr);
string retureJson= jsonHelper.HttpPost(jsonStr);
var jObject = JObject.Parse(retureJson);
有看不懂可以直接联系我！
