WebService学习(十三)——调用webservice的方式（其他方式）

1.使用ajax调用

var xhr;
function invoke(){
    if(window.ActiveXObject){
        xhr = new ActiveXObject("Microsoft.XMLHTTP");
    }else{
        xhr = new XMLHttpRequest();
    }
    //指定请求地址
    var url = "http://127.0.0.1:7777/hello?wsdl";
    //定义请求类型和地址和异步
    xhr.open("POST", url, true);
    //设置Content-Type
    xhr.setRequestHeader("Content-Type", "text/xml;charset=UTF-8");
    //指定回调方法
    xhr.onreadystatechange = back;
 
 
    var textVal = document.getElementById("mytext").value;
    //组装消息体的数据
    var data = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:q0="http://server.hm.com/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">'
    +'<soapenv:Body>'
    +'<q0:sayHello>'
    +'<arg0>'+textVal+'</arg0>'
    +'</q0:sayHello>'
    +'</soapenv:Body>'
    +'</soapenv:Envelope>';
    xhr.send(data);
 
 
}
function back(){
    if(xhr.readyState == 4){
        if(xhr.status == 200){
            var doc = xhr.responseXML;
            alert(doc);
            alert(xhr.responseText);
            var tag = doc.getElementsByTagName("return")[0];
            alert(tag)
 
 
        }
    }
}

2.通过URLConnection调用

//创建url地址
URL url = new URL("http://192.168.1.104:8080/hello");
//打开连接
URLConnection conn = url.openConnection();
//转换成HttpURL
HttpURLConnection httpConn = (HttpURLConnection) conn;
//打开输入输出的开关
httpConn.setDoInput(true);
httpConn.setDoOutput(true);
//设置请求方式
httpConn.setRequestMethod("POST");
//设置请求的头信息
httpConn.setRequestProperty("Content-type", "text/xml;charset=UTF-8");
//拼接请求消息
String data = "<soapenv:Envelope xmlns:soapenv=" +
        "\"http://schemas.xmlsoap.org/soap/envelope/\" " +
        "xmlns:q0=\"http://server.rl.com/\" " +
        "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" " +
        "xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">"
        +"<soapenv:Body>"
        +"<q0:sayHello>"
        +"<arg0>renliang</arg0> "
      +"</q0:sayHello>"
      +"</soapenv:Body>"
      +"</soapenv:Envelope>";
//获得输出流
OutputStream out = httpConn.getOutputStream();
//发送数据
out.write(data.getBytes());
//判断请求成功
if(httpConn.getResponseCode() == 200){
    //获得输入流
    InputStream in = httpConn.getInputStream();
    //使用输入流的缓冲区
    BufferedReader reader = new BufferedReader(new InputStreamReader(in));
    StringBuffer sb = new StringBuffer();
    String line = null;
    //读取输入流
    while((line = reader.readLine()) != null){
        sb.append(line);
    }
    //创建sax的读取器
    SAXReader saxReader = new SAXReader();
    //创建文档对象
    Document doc = saxReader.read(new StringReader(sb.toString()));
    //获得请求响应return元素
    List<Element> eles = doc.selectNodes("//return");
    for(Element ele : eles){
        System.out.println(ele.getText());
    }
}

3、使用jquery调用cxf

$(function(){
        $("#mybutton").click(function(){
            var data = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:q0="http://server.web.cxf.rl.com/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">'
                  +'<soapenv:Body>'
                  +'<q0:sayHello>'
                  +'   <arg0>sss</arg0>'
                  +' </q0:sayHello>'
                  +'</soapenv:Body>'
                  +'</soapenv:Envelope>';
 
 
                $.ajax({
                    url:'http://localhost:8080/cxf-web-server/services/hello',
                    type:'post',
                    dataType:'xml',
                    contentType:'text/xml;charset=UTF-8',
                    data:data,
                    success:function(responseText){
                        alert($(responseText).find('return').text());
                    },
                    error:function(){
                        alert("error");
                    }
                })
        })
    })
