HttpPut,HttpPost,HttpDelete,HttpGet请求

1，HttpPut

CloseableHttpClient httpclient = HttpClientFactory

.createBasicHtppClient();

HttpPut put = new HttpPut(url+"?"+concatParams(map));

StringEntity params =new StringEntity(JSONObject.fromObject(map).toString(),"utf-8");

put.setHeader("Content-type", "application/json");

put.setEntity(params);

HttpResponse response = httpclient.execute(put);

System.out.println("Response Code:"+response.getStatusLine().getStatusCode());

BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

StringBuffer result = new StringBuffer();

String line = "";

while ((line = rd.readLine()) != null) {

result.append(line);

}

System.out.println("result:"+result);

2，HttpPost

CloseableHttpClient httpclient = HttpClientFactory

.createBasicHtppClient();

StringPostRequest stringPostRequest=new StringPostRequest(url);

stringPostRequest.setQueryMap(map);

stringPostRequest.setContentType("application/json");

stringPostRequest.setContent(JSONObject.fromObject(map).toString());

String request=stringPostRequest.execute(httpclient);

System.out.println(request);

3,HttpDelete

CloseableHttpClient httpclient = HttpClientFactory.createBasicHtppClient();

HttpDelete httpDelete = new HttpDelete(url+"?"+concatParams(map));

HttpResponse response = httpclient.execute(httpDelete);

System.out.println("Response Code:"+response.getStatusLine().getStatusCode());

BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

StringBuffer result = new StringBuffer();

String line = "";

while ((line = rd.readLine()) != null) {

result.append(line);

}

System.out.println("result:"+result);

4,HttpGet

CloseableHttpClient httpclient = HttpClientFactory.createBasicHtppClient();

HttpGetRequest httpGet = new HttpGetRequest(url);

                httpGet.setQueryMap(map);

String repose = httpGet.execute(httpclient);

System.out.println(repose);

参数用&链接并按字母排序

public static String concatParams(Map<String, String> params2) {

        Object[] key_arr = params2.keySet().toArray();

        Arrays.sort(key_arr);

        String str = "";

        for (Object key : key_arr) {

            String val = params2.get(key);

            str += "&" + key + "=" + val;

        }

        return str.replaceFirst("&", "");

    }
