http 请求工具

import org.apache.http.client.fluent.Form;import org.apache.http.client.fluent.Request;

publicString post(String url, Map<String,String> param) throws Exception{   Form form = Form.form();   for(String key : param.keySet()){      form.add(key, param.get(key));   }   return Request.Post(url).connectTimeout(CONNECT_TIMEOUT).socketTimeout(SOCKET_TIMEOUT).
bodyForm(form.build(), utf8).execute().returnContent().asString(utf8);}
get方式同理
public static String get(String url, Map<String,String> param) throws Exception{   StringBuilder sb = new StringBuilder(url + "?");   if(param != null && !param.isEmpty()){      for(String key : param.keySet()){         sb.append(key).append("=").append(param.get(key)).append("&");      }      sb.deleteCharAt(sb.length() - 1);   }   return Request.Get(url).execute().returnContent().asString(utf8);}

返回不同的方式,有以下方式
// Read String objectString stringResult = Request.Get("http://ip:port").execute().returnContent().asString();System.out.println(stringResult);// Read String object with CharsetString stringResultWithCharset = Request.Get("http://ip:port").execute().returnContent().asString(Charset.defaultCharset());System.out.println(stringResultWithCharset);// Read Stream ObjectInputStream is = Request.Get("http://ip:port").execute().returnContent().asStream();// Handle the input streamis.close();// Read raw bytesbyte[] bytes = Request.Get("http://ip:port").execute().returnContent().asBytes();System.out.println(bytes.length);// Read int variableint intResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.IntConverter());System.out.println(intResult);// Read long variablelong longResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.LongConverter());System.out.println(longResult);// Read float variablefloat floatResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.FloatConverter());System.out.println(floatResult);// Read double variabledouble doulbeResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.DoubleConverter());System.out.println(doulbeResult);// Read BigDecimal objectBigDecimal bitDecimalResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.BitDecimalConverter());System.out.println(bitDecimalResult);// Read BeanStudent beanResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.Json2BeanConverter(Student.class));System.out.println(beanResult);// Read Bean ListList<Student> beanListResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.Json2BeansConverter(Student.class));System.out.println(beanListResult);// Read XML Document objectDocument documentResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.Xml2DocumentConverter());System.out.println(documentResult.toString());// Read JSONObject objectJSONObject jsonObjectResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.Json2ObjectConverter());System.out.println(jsonObjectResult.toJSONString());// Read JSONObject object arrayJSONArray jsonObjectArrayResult = Request.Get("http://ip:port").execute().handleResponse(HttpHelper.Json2ObjectsConverter());System.out.println(jsonObjectArrayResult.toJSONString());
