使用Ajax和HttpURLConnection發送webservice請求（cxf3）

其實質就是向webservice放送soap信息，好比上一篇的soap信息爲

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Header><daidao><name>kevin</name><password>123456</password></daidao></soap:Header>
    <soap:Body><ns2:selectByPrimaryKey xmlns:ns2="http://service.cxf.rain6.com/"><arg0>143347</arg0></ns2:selectByPrimaryKey>
    </soap:Body>
</soap:Envelope>

1.Ajax（會有跨域的問題）

　主要就是js代碼

$("#btn").click(function(){ //回調函數
            var name = document.getElementById("name").value; var data = 'soap信息'; $.ajax({ type : "post", url : "http://localhost:8092/webservice/testService", data : data, success : function(msg){ alert("------"); var $Result = $(msg); var value = $Result.find("return").text(); alert(value); }, error : function(msg) { //alert("-----"+msg);
 }, dataType : "xml" }); });

2.HttpURLConnection

　　1)簡單點，直接web.xml配置該sevlet

<servlet>
        <description></description>
        <display-name>HttpURLConnectionServlet</display-name>
        <servlet-name>HttpURLConnectionServlet</servlet-name>
        <servlet-class>httptows.HttpURLConnectionServlet</servlet-class>
</servlet>
<servlet-mapping>
        <servlet-name>HttpURLConnectionServlet</servlet-name>
        <url-pattern>/HttpURLConnectionServlet</url-pattern>
</servlet-mapping>

　　2)HttpURLConnectionServlet.java

public class HttpURLConnectionServlet { private static final long serialVersionUID = 1L; protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String name = request.getParameter("name"); System.out.println("doPost "+name); String data = "soap信息";
　　　　　//localhost建議改成ip地址 URL url = new URL("http://localhost:8092/webservice/testService"); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("POST"); connection.setDoOutput(true); connection.setDoInput(true); connection.setRequestProperty("Content-Type", "text/xml;charset=utf-8"); OutputStream os = connection.getOutputStream(); os.write(data.getBytes("utf-8")); int responseCode = connection.getResponseCode(); if(responseCode==200) { InputStream is = connection.getInputStream();//String xml
            System.out.println("return "+is.available()); response.setContentType("text/xml;charset=utf-8"); ServletOutputStream outputStream = response.getOutputStream(); byte[] buffer = new byte[1024]; int len = 0; while((len=is.read(buffer))>0) { outputStream.write(buffer, 0, len); } outputStream.flush(); } } }

 　　3)前端調用

$("#btn2").click(function(){ var name = document.getElementById("name").value; $.post( "HttpURLConnectionServlet", "name="+name, function(msg) { //alert(msg);
               var $Result = $(msg); var value = $Result.find("return").text(); alert(value); }, "xml" ); });
