httpclient 获取表单提交返回数据(取table 中的数据)

以http://haoma.imobile.com.cn/index.php?mob= 为例

mob 是手机号码参数.

 

通过 httpClient 进行页面的请求,并返回结果页面的源码:

View Code

public class SimpleHttpClient {

    public static void main(String[] args) throws HttpException, IOException,
            ParserException {
        HttpClient client = new HttpClient();
        client.getHostConfiguration().setHost("haoma.imobile.com.cn", 80,
                "http");

        System.out.println("method:" + getPostMethod().getStatusLine());
        HttpMethod method = getPostMethod();
        client.executeMethod(method);
        String response = new String(method.getResponseBodyAsString().getBytes(
                "gbk"));
    }
        
    private static HttpMethod getPostMethod() {
            PostMethod post = new PostMethod("/index.php");
            NameValuePair simcard = new NameValuePair("mob", "13979146891");
            post.setRequestBody(new NameValuePair[] { simcard });
            return post;
        }
    
}

返回的页面:

接下来，通过htmlparser ,解析源码中的table内容:

    /**
     * html源码处理
     * @param response
     * @throws ParserException
     */
    private static void deal_resource(String response) throws ParserException {

        Parser parser = Parser.createParser(response, "gbk");
        HtmlPage page = new HtmlPage(parser);

        parser.visitAllNodesWith(page);

        NodeList nodeList = page.getBody();

        NodeFilter filter = new TagNameFilter("table");

        nodeList = nodeList.extractAllNodesThatMatch(filter, true);

        TableTag tag = (TableTag) nodeList.elementAt(0);

        for (int i = 0; i < tag.getChildCount(); i++) {
            NodeList nodelist1 = tag.getChild(i).getChildren();
            if (nodelist1 != null) {
                for (int j = 0; j < nodelist1.size(); j++) {
                    System.out.println("nodeList.elementAt(i).toHtml():"
                            + nodelist1.elementAt(j).toPlainTextString());
                }
            }
        }
    }
