如何使用Java Rest客户端在POST有效负载中传递参数'request'？

Question

我从Java rest客户端调用rest api。 geoanalytics

private static void BatchGeoCodingProcess() throws JSONException, ClientProtocolException, IOException {
		  System.out.println("BatchGeoCodingProcess...................................");		
/*
 
 {
  "coder": {
    "addresses": [
      {
        "id": "2824",
        "countrycode": "FR",
        "longitude": "2.33",
        "latitude": "48.88",
        "maxdist": "20000"
      },
      {
        "id": "6404",
        "countrycode": "FR",
        "street": "1598 ROUTE DE QUARANTE SOUS",
        "zipcode": "78630",
        "city": "ORGEVAL"
      }
    ]
  },
  "encoding": "utf-8"
}
 		
 */
		  JSONObject req = new JSONObject();
	
		JSONObject jsonObj = new JSONObject();
		req.put("request", jsonObj);
		
		JSONObject coder = new JSONObject();
		jsonObj.put("coder", coder);
		jsonObj.put("encoding", "utf-8");
		JSONArray addrList = new JSONArray();
		coder.put("addresses", addrList);
		
		// Reverse geo code
		JSONObject addr = new JSONObject();
		addr.put("id", "2824");
		addr.put("countrycode", "FR");
		addr.put("longitude", "2.33");
		addr.put("latitude", "48.88");
		
		addrList.put(addr);
		
		// geo code
		addr = new JSONObject();
		addr.put("id", "6404");
		addr.put("countrycode", "FR");
		addr.put("street", "1598 ROUTE DE QUARANTE SOUS");
		addr.put("zipcode", "78630");
		addr.put("city", "ORGEVAL");
		
		 addrList.put(addr);
		 HttpClient client = new DefaultHttpClient();
	
		 HttpPost request = new HttpPost("http://geowebservices.maporama.com/demo/batchcoder.json?maporamakey=2u7kdn4DnYE=&");
		 request.addHeader("content-type", "application/json");
		 //request.addHeader("Accept", "application/json");
		 
	     System.out.println("test = "+req.toString());
		 StringEntity body = new StringEntity(req.toString());
		 request.setEntity(body);
		 
		  HttpResponse response = client.execute(request);
		  int code = response.getStatusLine().getStatusCode();
		  String reason = response.getStatusLine().getReasonPhrase();
		  String test = EntityUtils.toString(response.getEntity());
		  System.out.println("Code = "+code+" :: Reason = "+reason);
		  System.out.println("Batch geocode");
		  System.out.println("test..."+test);
		  System.out.println("Batch geocode");
		  
	}

使用

List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
        urlParameters.add(new BasicNameValuePair("request", jsonObj.toString()));

和 评论

request.addHeader("content-type", "application/json");
