最近通过调用另一个合作公司提供的接口实现方法,借鉴同事之前编写的方法
Models.JSON.Patient类中有各种属性,也可增加属性来满足新需求
public string TakeAppoint(string AppointCode, string RefundAmount, string BusinessSource)
{
try
{
//调用地址
string strUrl = UrlSet.Default.UrlTakeAppoint;
//将参数赋入地址
strUrl = string.Format(strUrl, AppointCode, RefundAmount, BusinessSource);
//调用web
string returnValue = Analytical.Invoke(strUrl);
//解析返回值
Models.JSON.Patient patient = Analytical.AnalyticalJson(returnValue);
if (Analytical.errCode < 1)
{
this.errCode = Analytical.errCode;
this.errMsg = Analytical.errMsg;
return "-1|" + Analytical.errMsg;
}
return "1|" + AppointCode + "|" + RefundAmount + "|" + BusinessSource;
}
catch (Exception ex)
{
this.errCode = -1;
this.errMsg = ex.Message + ex.StackTrace;
Logger.WriteLog(errMsg, true);
return "-1|" + errMsg;
}
}
下面的方法可以从返回的URL串中获取需要的参数
public static string Invoke(string strUrl)
{
string returnValue = string.Empty;
try
{
Logger.FolderName = "CAREATE";
Logger.WriteLog(string.Format(Logger.ProcessHISMessageFormat, "入参", strUrl, "", ""), false);
// 调用接口
System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(strUrl);
System.Net.HttpWebResponse response = (System.Net.HttpWebResponse)request.GetResponse();
System.IO.StreamReader streamRead = new System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8);
returnValue = streamRead.ReadToEnd();
streamRead.Close();
Logger.FolderName = "CAREATE";
Logger.WriteLog(string.Format(Logger.ProcessHISMessageFormat, "出参", strUrl, returnValue, ""), false);
return returnValue;
}
catch (Exception ex)
{
return returnValue;
}
}
解析返回值,赋入Models.JSON.Patient实体中
public static Models.JSON.Patient AnalyticalJson(string returnValue)
{
Models.JSON.Patient patient = new Models.JSON.Patient();
if (string.IsNullOrEmpty(returnValue))
{
errCode = -1;
errMsg = "未获取到数据!";
return patient;
}
// 取result值
JObject jsMessage = JObject.Parse(returnValue);
string returnCode = (string)jsMessage["result"];
if (returnCode == "-1")
{
errCode = -1;
errMsg = (string)jsMessage["message"];
return null;
}
// 解析返回值编码
string msg = AnalyticalCode(returnCode);
if (!string.IsNullOrEmpty(msg))
{
errCode = -1;
errMsg = msg;
return patient;
}
// 返回数据行数
int rows = Convert.ToInt32(jsMessage["data"]["total"].ToString());
if (rows < 0)
{
errCode = -1;
errMsg = "未获取到数据!";
return patient;
}
JArray jar = JArray.Parse(jsMessage["data"]["rows"].ToString());
patient = Deserialize<Models.JSON.Patient>(jar[0].ToString());
errCode = 1;
return patient;
}
