怎么写响应http请求的代码并返回参数？

RequestBody body = RequestBody.create(MediaType.parse("text/xml;charset=UTF-8"), soapRequestData);
       Request request = new Request.Builder()
               .url("https:api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack")
               .post(body)
               .build();
       //为http请求设置证书
       SSLSocketFactory socketFactory = getSSL().getSocketFactory();
       X509TrustManager x509TrustManager = Platform.get().trustManager(socketFactory);
      OkHttpClient okHttpClient = new OkHttpClient.Builder().sslSocketFactory(socketFactory, x509TrustManager).build();
      // 得到输出内容
       Response response = okHttpClient.newCall(request).execute();
      String content = response.body().string();

我想把url换成本地的127.0.0.1，编写一个运行在Tomcat的代码，响应上面那个请求并返回参数，请问该怎么写啊？
