一個簡單的Get請求
HttpRequest httpRequest = HttpRequest.get("http://jodd.org"); HttpResponse response = httpRequest.send(); //更簡潔的一種寫法 HttpResponse response = HttpRequest.get("http://jodd.org").send(); System.out.println(response);輸出結果如下：
//下面是響應頭信息 HTTP/1.1 200 OK Accept-Ranges: bytes Cache-Control: max-age=0, public Connection: close Content-Length: 15441 Content-Type: text/html; charset=utf-8 Date: Mon, 04 Jul 2016 14:26:08 GMT Expires: Mon, 04 Jul 2016 14:26:08 GMT Last-Modified: Thu, 24 Mar 2016 23:05:05 GMT Server: nginx/1.10.1 Vary: Accept-Encoding <!DOCTYPE html> <html> ...... </html>//省略部分是訪問頁面的HTML頁面
較為復雜一點的get請求：
HttpRequest request = new HttpRequest(); request .method("GET")//get請求 .protocol("http")//協議使用http .host("jodd.org")//主機地址 .port(80)//端口，沒有寫默認是80 .path("/api/jsonws/user/get-user-by-id");//訪問路徑HttpResponse對象中有下面三個方法：
body() - 返回ISO-8859-1編碼的response返回體（上面的訪問對應的是jodd的html源碼）
bodyText() - 返回與響應頭中相應編碼的response返回體
bodyBytes() - 返回返回體的字節碼
參數
//get訪問中直接在URL中傳遞參數 HttpResponse response = HttpRequest .get("http://srv:8080/api/jsonws/user/get-user-by-id?userId=10194") .send(); //調用方法的方式傳遞參數 HttpResponse response = HttpRequest .get("http://srv:8080/api/jsonws/user/get-user-by-id") .query("userId", "10194") .send(); //或者創建request對象后用以下map的方式傳遞參數 Map<String, Object[]> httpParams = request.query(); httpParams.put("userId", new String[] {"10194"});基本的用戶認證請求
request.basicAuthentication("test", "test");//是不是很方便啊POST請求
HttpResponse response = HttpRequest
.post("http://srv:8080/api/jsonws/user/get-user-by-id") .form("userId", "10194")//這里與get的參數傳遞方式不同 .send();上傳文件
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();還可以設置回調方法監聽上傳的進度等：
HttpResponse response = HttpRequest
.post("http://localhost:8081/hello") .form("file", file) .monitor(new HttpProgressListener() {//監聽上傳的進度 @Override public void transferred(long len) { System.out.println(len/size); } }) .send();請求頭等信息的設置 HttpRequest中提供了header的多種不同方法簽名的傳遞header的方法，還提供headers使用map傳遞header的方法使用起來十分方便。 此為還提供contentType、cookie的等方法操作相關內容【具體可以看HttpRequest的API】
GZIP
有些網站使用了GZIP壓縮技術，這就要求獲得請求的時候使用GZIP解壓才能獲得數據，jodd提供了相關的支持而且使用十分簡單：
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();編碼設置
HttpResponse response = HttpRequest
.get("http://server/index.html") .queryEncoding("CP1251") .query("param", "value") .send();Soket連接
HttpRequest request = HttpRequest.get()...;
request.open();
SocketHttpConnection httpConnection =
(SocketHttpConnection) request.httpConnection();
Socket socket = httpConnection.getSocket();
socket.setSoTimeout(1000); ... HttpResponse response = request.send();長連接
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();
