简单HttpClient 发送post json请求

直接上代码

构建post请求

    public static String post(String url, JSONObject json, int timeOut) throws UnsupportedEncodingException {
        PostMethod method = new PostMethod(url);
        method.setRequestEntity(new StringRequestEntity(json.toJSONString(), "application/json", StandardCharsets.UTF_8.name()));
        return request(method, timeOut);
    }

发送请求

   public static String request(HttpMethod method, int timeOut) {
        HttpClient httpClient = new HttpClient();
        HostConfiguration hc = new HostConfiguration();
//      hc.setProxy(ip, port);代理
        httpClient.setHostConfiguration(hc);
        httpClient.getParams().setConnectionManagerTimeout(timeOut * 1000);
        httpClient.getParams().setSoTimeout(timeOut * 1000); // 120s timeout
        try {
            int statusCode = httpClient.executeMethod(method);
            if (statusCode != HttpStatus.SC_OK) {
                throw new RuntimeException("request status code error: " + statusCode);
            }
            return method.getResponseBodyAsString();
        } catch (Exception e) {
            throw new RuntimeException("request exception："+e.getMessage(), e);
        } finally {
            method.releaseConnection();
        }
    }
