  • C#中请求接口代码,并将返回报文解析

    工作中用到的,记录下!

    //接口调用
    private string InterfaceRequest(string url,string reqmsg,ref string errormsg)
    {
      try
      {
        Logger.WriteLine("[TsCustomer][CustomerPortrait][InterfaceRequest] url={0},reqmsg={1},errormsg={2}",url,reqmsg,errormsg);
        //按照utf8进行编码
        Encoding enc = Encoding.UTF8;
        byte[] info = enc.GetBytes(reqmsg);
        //调用
        HttpWebRequest hwr=HttpWebRequest.Create(url) as HttpWebRequest;
        hwr.Timeout = 30000;//超时时间
        hwr.Method = "POST";//提交方式
        hwr.ContentType = "application/json";//请求类型
        hwr.UserAgent = "Interact AppServer";
        hwr.ContentLength = info.Length; //内容长度
        Stream st = hwr.GetRequestStream(); //获取请求流
        st.Write(info, 0, info.Length);
        st.Close();
        //读取结果,向接口发送请求
        HttpWebResponse response = hwr.GetResponse() as HttpWebResponse;
        StreamReader reader = new StreamReader(response.GetResponseStream(), enc);

        string respmsg = reader.ReadToEnd();
        reader.Close();
        Logger.WriteLine("[CustomerPortrait][InterfaceRequest] url=[{0}] recvmsg=[{1}]",url,respmsg);
        return respmsg;
      }
      catch(Exception ex)
      {
        LogBlockWriter lbw=Logger.BeginWriteBlock();
        lbw.WriteLine("[CustomerPortrait][InterfaceRequest]Exception");
        lbw.WriteLine(ex);
        Logger.EndWriteBlock(lbw);
        errormsg = ex.Message;
        return "";
      }
    }

    //respmsg 接口返回报文

    //RecreationClubPresent_url 接口地址(接口地址是放在数据库里的,方便更改)

    //errormsg (如果请求接口有错误,用来传递报错信息)

    string respmsg = InterfaceRequest(RecreationClubPresent_url,reqmsg,ref errormsg);

    //解析报文

    private string PersonalCenterPresent_msgParse(string respmsg,string PersonalCenterPresent_url)
    {
      DataRecordSet drs = new DataRecordSet();
      string errormsg="";
      try
      {

        //转换返回报文的数据类型
        JsonObject joret = JsonObject.Decode(respmsg);
        if (joret == null)
        {
          errormsg = "读取接口返回结果失败";
          Logger.WriteLine("[CustomerPortrait][GetPortrait] error:读取返回结果失败");
          drs.SetAttribute("result", errormsg);
          return drs.ToXmlDocument().OuterXml;
        }

        //获取报文中“header”节点的数据
        JsonObject header = joret["header"].ObjectValue();
        if(header["resMsg"].ToString().Length > 0 && !header["resMsg"].ToString().Equals("查询到数据"))

        {
          errormsg = header["resMsg"].ToString();
          drs.SetAttribute("result", errormsg);
          return drs.ToXmlDocument().OuterXml;
        }

        //body节点值
        JsonObject body = joret["body"].ObjectValue();
        if(body == null)
        {

          Logger.WriteLine("[CustomerPortrait][GetPortrait] error:读取接口返回结果失败");
          drs.SetAttribute("result", errormsg);
          return drs.ToXmlDocument().OuterXml;
        }
         //获取"body"节点中的"physicalGifts"数组节点
        JsonKeyValue physicalGifts = body["physicalGifts"];

        if(physicalGifts != null && physicalGifts.ToString() != "")
        {  

          //physicalGifts转换类型
          ArrayList physicalGiftsList = physicalGifts.ArrayValue();
          if(physicalGiftsList.Count > 0)
          {

            //循环把数据取出转换成DataRecord类型
            for(int i = 0;i<physicalGiftsList.Count;i++)
            {
              DataRecord physicalGift = new DataRecord("physicalGift");
              JsonObject physicalGiftj = physicalGiftsList[i] as JsonObject;
              physicalGift.AddField("activityName",physicalGiftj["activityName"].ToString());
              physicalGift.AddField("giftName",physicalGiftj["giftName"].ToString());
              physicalGift.AddField("useDateStr",physicalGiftj["useDateStr"].ToString());
              drs.AddRecord(physicalGift);
            }
          }

      }

      catch(Exception ex)
      {

        lbw.WriteLine("[CustomerPortrait][PersonalCenterPresent_msgParse]Exception");
        lbw.WriteLine(ex);

      }
