Java模拟HTTP/POST方式请求接口

Java模拟HTTP/POST方式请求接口：

java模拟http/post方式请求接口方法主体：

public String sendPost(JSONObject json, String url){
    String result = "";
    HttpPost post = new HttpPost(url);
    try{
        CloseableHttpClient httpClient = HttpClients.createDefault();
        post.setHeader("Content-Type","application/json;charset=utf-8");
        post.addHeader("Authorization", "Basic YWRtaW46");
        StringEntity postingString = new StringEntity(json.toString(),"utf-8");
        post.setEntity(postingString);
        HttpResponse response = httpClient.execute(post);

        InputStream in = response.getEntity().getContent();
        BufferedReader br = new BufferedReader(new InputStreamReader(in, "utf-8"));
        StringBuilder strber= new StringBuilder();
        String line = null;
        while((line = br.readLine())!=null){
            strber.append(line+'\n');
        }
        br.close();
        in.close();
        result = strber.toString();
        if(response.getStatusLine().getStatusCode()!= HttpStatus.SC_OK){
            result = "服务器异常";
        }
    } catch (Exception e){
        System.out.println("请求异常");
        throw new RuntimeException(e);
    } finally{
        post.abort();
    }
    return result;
}

接口调用方法：

 public String sendPostTest() {
    JSONObject jsonObject = new JSONObject();
    //添加参数，参数为JSON格式
    jsonObject.put("namecode", "zhouxf4110");
    String url = "http://localhost/***/userMassage/queryUserByList";
    //调用接口，返回字符串,返回值自行处理
    String str = sendPost(jsonObject, url);
    System.out.println(str);
    return str;
}
