使用

1、初始化

HttpUtil.init("UTF-8", null);

2、发送GET请求

byte[] result = HttpUtil.send(null, "http://172.27.108.74:8080/UCenter", null, HttpUtil.GET);
String str = new String(result, "UTF-8");

3、发送POST请求

String str = "{hOpCode: 20, userName: \"admin\", userPassword: \"123456\"}";
HashMap<String, String> headMap = new HashMap<String, String>();
headMap.put("hOpCode", "20");
headMap.put("sendType", "sendTypeJson");
headMap.put("receiveType", "receiveTypeJson");
byte[] result = HttpUtil.send(str, "http://172.27.108.74:8080/UCenter/s", headMap, HttpUtil.POST);
String returnStr = new String(result, "UTF-8");

4、发送文件

String tokenId = "38bfecab619b48db8466ea7dd064f0d8";
String str = "{hOpCode: 10, userName: \"dianbaer333\", userPassword: \"123456\"}";
HashMap<String, String> headMap = new HashMap<String, String>();
headMap.put("hOpCode", "10");
headMap.put("sendType", "sendTypeFileSaveSession");
headMap.put("receiveType", "receiveTypeJson");
headMap.put("token", tokenId);
headMap.put("packet", URLEncoder.encode(str, HttpUtil.ENCODE));
File file = new File("C:\\Users\\admin\\Desktop\\github\\grain\\trunk\\grain-httpclient\\src\\test\\resources\\k_nearest_neighbors.png");
byte[] result = HttpUtil.sendFile(file, "http://172.27.108.74:8080/UCenter/s", headMap, HttpUtil.POST);
String returnStr = new String(result, "UTF-8");
