介紹一個方便調用RESTful services的Java 開源項目Resty

Resty項目地址在git下找一下應該能找的到。

Resty支援text, XML, JSON, binary。使用非常方便，官網有非常詳細的使用說明。

為了給大家一個感性的認識，下面給一個XML的執行個體，且解決了中文亂碼問題：

        Resty r = new Resty();
        NodeList nl=r.xml("http://218.22.67.142:8080/geoserver/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=wuhu:shuili_hanzhadoumen&maxFeatures=5").get("FeatureCollection/featureMember/shuili_hanzhadoumen/name");
for (int i = 0, len = nl.getLength(); i < len; i++) {
            Node node=(Node)nl.item(i);
            System.out.println(new String(node.getTextContent().getBytes("ISO-8859-1"),"GBK"));
        }

輸出結果：

雙擺渡閘站
犁頭尖站（閘）
王村站閘
保順站閘
