Jodd HTTP的使用

来源：互联网发布：windows截屏编辑：程序博客网时间：2024/06/10 21:55

一个简单的Get请求

HttpRequest httpRequest = HttpRequest.get("http://jodd.org");HttpResponse response = httpRequest.send();//更简洁的一种写法    HttpResponse response = HttpRequest.get("http://jodd.org").send();System.out.println(response);

输出结果如下：

//下面是响应头信息HTTP/1.1 200 OKAccept-Ranges: bytesCache-Control: max-age=0, publicConnection: closeContent-Length: 15441Content-Type: text/html; charset=utf-8Date: Mon, 04 Jul 2016 14:26:08 GMTExpires: Mon, 04 Jul 2016 14:26:08 GMTLast-Modified: Thu, 24 Mar 2016 23:05:05 GMTServer: nginx/1.10.1Vary: Accept-Encoding<!DOCTYPE html><html>......</html>

//省略部分是访问页面的HTML页面
较为复杂一点的get请求：

HttpRequest request = new HttpRequest();request    .method("GET")//get请求    .protocol("http")//协议使用http    .host("jodd.org")//主机地址    .port(80)//端口，没有写默认是80    .path("/api/jsonws/user/get-user-by-id");//访问路径

HttpResponse对象中有下面三个方法：

body() - 返回ISO-8859-1编码的response返回体（上面的访问对应的是jodd的html源码）
bodyText() - 返回与响应头中相应编码的response返回体
bodyBytes() - 返回返回体的字节码
参数

//get访问中直接在URL中传递参数HttpResponse response = HttpRequest    .get("http://srv:8080/api/jsonws/user/get-user-by-id?userId=10194")    .send();//调用方法的方式传递参数HttpResponse response = HttpRequest    .get("http://srv:8080/api/jsonws/user/get-user-by-id")    .query("userId", "10194")    .send();//或者创建request对象后用以下map的方式传递参数Map<String, Object[]> httpParams = request.query();httpParams.put("userId", new String[] {"10194"});

基本的用户认证请求

request.basicAuthentication("test", "test");//是不是很方便啊

POST请求

HttpResponse response = HttpRequest    .post("http://srv:8080/api/jsonws/user/get-user-by-id")    .form("userId", "10194")//这里与get的参数传递方式不同    .send();

上传文件

HttpRequest httpRequest = HttpRequest    .post("http://srv:8080/api/jsonws/dlapp/add-file-entry")    .form(        "repositoryId", "10178",        "folderId", "11219",        "sourceFileName", "a.zip",        "mimeType", "application/zip",        "title", "test",        "description", "Upload test",        "changeLog", "testing...",        "file",new File("d:\\a.jpg.zip")    );HttpResponse httpResponse = httpRequest.send();

还可以设置回调方法监听上传的进度等：

HttpResponse response = HttpRequest    .post("http://localhost:8081/hello")    .form("file", file)    .monitor(new HttpProgressListener() {//监听上传的进度        @Override        public void transferred(long len) {            System.out.println(len/size);        }    })    .send();

请求头等信息的设置 HttpRequest中提供了header的多种不同方法签名的传递header的方法，还提供headers使用map传递header的方法使用起来十分方便。此为还提供contentType、cookie的等方法操作相关内容【具体可以看HttpRequest的API】
GZIP
有些网站使用了GZIP压缩技术，这就要求获得请求的时候使用GZIP解压才能获得数据，jodd提供了相关的支持而且使用十分简单：

HttpResponse response = HttpRequest    .get("http://www.liferay.com")    .acceptEncoding("gzip")    .send();System.out.println(response.unzip());

body

HttpResponse response = HttpRequest    .get("http://srv:8080/api/jsonws/invoke")    .body("{'$user[userId, screenName] = /user/get-user-by-id' : {'userId':'10194'}}")    .basicAuthentication("test", "test")    .send();

编码设置

HttpResponse response = HttpRequest    .get("http://server/index.html")    .queryEncoding("CP1251")    .query("param", "value")    .send();

Soket连接

HttpRequest request = HttpRequest.get()...;request.open();SocketHttpConnection httpConnection =    (SocketHttpConnection) request.httpConnection();Socket socket = httpConnection.getSocket();socket.setSoTimeout(1000);...HttpResponse response = request.send();

长连接

HttpRequest request = HttpRequest.get("http://jodd.org");    HttpResponse response = request.connectionKeepAlive(true).send();    // next request    request = HttpRequest.get("http://jodd.org/jodd.css");    response = request.keepAlive(response, true).send();    ...    // last request    request = HttpRequest.get("http://jodd.org/jodd.png");    response = request.keepAlive(response, false).send();    // optionally    //response.close();
