SSM中通过okhttp3向接口发送xml格式的请求参数

场景

在SSM项目中的后台Controller中需要想asp的接口发送xml格式的请求参数。

依据接口文档示例代码。

入参:

<Request>
  <ServiceCode>get_fight</ServiceCode>
  <Pid>111111</Pid>
  <UserName>badao</UserName>
  <Sign>222222</Sign>
  <Params>
    <DepartCity>SHA</DepartCity>
    <ArriveCity>SIN</ArriveCity>
    <StartDate>2019-07-23</StartDate>
  </Params>
</Request>

实现

项目中引入pom依赖

<dependency>
   <groupId>com.squareup.okhttp3</groupId>
   <artifactId>okhttp</artifactId>
   <version>3.6.0</version>
  </dependency>

实现代码

public static String GJticketBookJsonStr(GJBookParam bookParam) throws ParseException, IOException {
  SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
  Date now = new Date();
  String strNow = sdf.format(now);
  //使用StringBufer来拼接xml格式参数
  StringBuffer sbParams = new StringBuffer();
  //使用append方法来追加公共参数
  sbParams.append("<Flight>");
  sbParams.append("<DepartCity>").append(bookParam.getFlightInfo().getDepartCity()).append("</DepartCity>");
  sbParams.append("<ArriveCity>").append(bookParam.getFlightInfo().getArriveCity()).append("</ArriveCity>");
  sbParams.append("<StartDate>").append(bookParam.getFlightInfo().getStartDate()).append("</StartDate>");
  sbParams.append("<SeqNo>").append(bookParam.getFlightInfo().getSeqNo()).append("</SeqNo>");
  sbParams.append("</Flight>");

  sbParams.append("<PassengerInfo>");
  //通过循环拼接多个参数节点
  for(ParamGJPassenger passenger : bookParam.getPassengerInfo()) {
   sbParams.append("<Passenger>");
   sbParams.append("<SurName>").append(passenger.getSurName()).append("</SurName>");
   sbParams.append("<Name>").append(passenger.getName()).append("</Name>");
   sbParams.append("<PassType>").append(passenger.getPassType()).append("</PassType>");
   sbParams.append("<Sex>").append(passenger.getSex()).append("</Sex>");
   sbParams.append("<IdType>").append(passenger.getIdType()).append("</IdType>");
   sbParams.append("<IdDate>").append(passenger.getIdDate()).append("</IdDate>");
   sbParams.append("<Id>").append(passenger.getId()).append("</Id>");
   sbParams.append("<Country>").append(passenger.getCountry()).append("</Country>");
   sbParams.append("<CountryCode>").append(passenger.getCountryCode()).append("</CountryCode>");
   sbParams.append("<Birthdays>").append(passenger.getBirthdays()).append("</Birthdays>");
   sbParams.append("</Passenger>");
  }
  sbParams.append("</PassengerInfo>");

  //将多个参数节点格式化进请求参数中
  String sign = "%s%s%s%s%s"; 
  sign = String.format(sign, sbParams.toString(), "1111", ShiroHelper.md5Encrypt("111111", null, null, 1).toUpperCase(), strNow, "11111111");
  sign = ShiroHelper.md5Encrypt(sign, null, null, 1).toUpperCase();

  String request = "<Request><ServiceCode>%s</ServiceCode><Pid>%s</Pid><UserName>%s</UserName><Sign>%s</Sign><Params>%s</Params></Request>";
  request = String.format(request, "jiekouName", "111111", "1111111", sign, sbParams.toString());
  System.out.println(request);

  //客户端对象
  OkHttpClient client = new OkHttpClient();
  //请求体
  RequestBody body = RequestBody.create(MediaType.parse("application/xml;charset=utf-8"), request);
  //请求对象 url 请求头 post方式
  Request req = new Request.Builder().url("http://127.0.0.1:8888/test.aspx").header("Content-Type", "application/xml").post(body).build();

     //发送请求并接受收响应
  Response response = client.newCall(req).execute();
  if (!response.isSuccessful())
  {
   throw new IOException("Unexpected code " + response);
  }
  String jsonResult = response.body().string();
  return jsonResult;
 }
