-- from-date 形式的数据也能传
public static StringBuffer httpSaveFromDate(Map<String, Object> map, String uri, JSONObject jsonObject) {
HttpClient httpClient = new HttpClient();
//设置请求头的编码格式为UTF-8(这部分很重要要不然数据传递到接口中是乱码的) httpClient.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
//设置代理模式 httpClient.getHostConfiguration().setProxy (jsonObject.get("proxyHost").toString(), //第三方接口ip Integer.parseInt(jsonObject.get("proxyPort").toString())); //接口端口 httpClient.getParams().setAuthenticationPreemptive(true); HttpConnectionManagerParams managerParams = httpClient.getHttpConnectionManager().getParams(); //设置请求连接超时时间(毫秒值) managerParams.setConnectionTimeout(15000); //设置读取资源超时时间(毫秒值) managerParams.setSoTimeout(35000); //定义请求方式为post请求数据 PostMethod postMethod = new PostMethod(uri); String response = null; StringBuffer buffer = new StringBuffer(); try { //传入需要填写的请求的参数个数,比如接口要求 传递参数为5,那么new NameValuePair[5] NameValuePair[] par = new NameValuePair[Integer.parseInt(jsonObject.get("paramNumber").toString())]; int index = 0; for (String key : map.keySet()) { par[index++] = new NameValuePair(key, map.get(key).toString()); } postMethod.setRequestBody(par); int code = httpClient.executeMethod(postMethod); //判断响应状态是否为200 if (code != HttpStatus.SC_OK) { //抛出异常信息 throw new IllegalStateException("request error" + postMethod.getStatusLine()); } //定义一个bufferReader BufferedReader bufferedReader = null; bufferedReader = new BufferedReader(new InputStreamReader(postMethod.getResponseBodyAsStream(),StandardCharsets.UTF_8));
while ((response = bufferedReader.readLine()) != null) {
buffer.append(response);
}
} catch (Exception e) {
throw new IllegalStateException(e.getMessage());
} finally {
//关闭资源链接
postMethod.releaseConnection();
}
return buffer; //获取到的是服务器的响应参数
}
--- 获取当前时间将当前时间往后延长自定义天数
public static String plusDay(int numberDay){ Date date = new Date(); SimpleDateFormat simp = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Calendar calendar = Calendar.getInstance(); // num为增加的天数,可以改变的 calendar .add(Calendar.DATE, numberDay); date = calendar.getTime();
return format.format(date);
}
//例如:plusDay(5) --返回得到的是第五天的时间
ps:多嘴说下
httpSaveFromDate(Map<String,Object>map,String uri,JsonObject jsonObject) 这个方法的用法 如下:
public static void main(String[] args){
String uri ="http://localhost:8080/...." Map<String,Object> map =new HashMap<>(); map.put("key","value") map.put("key","value") JsonObject json =new JsonObject(); json.put("proxyHost","127.0.0.1"); jsonObject.put("proxyPort","8080"); jsonObject.put("paramNumber","5"); StringBuffer stringBuffer =httpSaveFromDate(map, uri, jsonObject); System.out.println(stringBuffer); }
感谢:.....找不到那个参考的博客了但是还是感谢大佬吧...
