java调用asmx的webservice

使用apache的httpclient组件进行调用。

需要的包：commons-codec-1.5.jar, commons-httpclient-3.1.jar, commons-logging-1.1.jar

调用代码如下：

    private static void clientDemo() throws HttpException, IOException {
        HttpClient httpClient = new HttpClient();
        // httpClient.getHostConfiguration().setProxy("127.0.0.1", 8888);
        //接口地址。后面的TestMethod表示方法名
        String url = "http://xxx.xxx.xxx.xxx:8089/service1.asmx/TestMethod";    
        PostMethod postMethod = new PostMethod(url);
        
        //编码设为UTF-8
        postMethod.getParams().setParameter(
                HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");    
        
        //NameValuePair 名值对。传入webservice的参数
        NameValuePair[] data = {
                new NameValuePair("name", "admin"),
                new NameValuePair("password", "admin"),
                new NameValuePair("message", "测试测试"),
        };
        postMethod.setRequestBody(data);
        //调用webservice，返回statuscode。200表示成功。
        int statusCode = httpClient.executeMethod(postMethod);    
        System.out.println(statusCode);
        //返回的Response文本。
        String soapRequestData = postMethod.getResponseBodyAsString();    
        System.out.println(soapRequestData);
    }
