jsouphttp's Introduction

JsoupHttp

通过云层接口视频，学习JsoupGet，jsoupPost package com.cloudits.get;

import java.io.IOException;

import javax.swing.plaf.synth.SynthScrollBarUI;

import org.jsoup.Connection; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; import org.omg.Messaging.SyncScopeHelper;

public class JsoupGet { Document doc =null; //无参数get方式 public Document GetUrl(String url){ try { // 抓取页面 doc = (Document) Jsoup.connect(url).get(); } catch (IOException e) {

		e.printStackTrace();
	}
	return doc;
}
//带参数的get方法
public Document GetUrl(String url,String param1,String param2){
	//http://yuedu.baidu.com/search?word=%D4%C6%B2%E3&pbook=0
	//百度阅读，搜索云层，提交的链接。
	try {
		// 
		Connection conn =  Jsoup.connect(url);
		conn.data("word", param1);
		conn.data("pbook", param2);
		doc = conn.get();
		
	} catch (IOException e) {			
		e.printStackTrace();
	}
	return doc;
}	

public static void main(String[] args) {
	
	/* 如果需要使用fiddler的mockserver ，则设置如下
	 * System.setProperty("http.proxySet", "ture");
	 * System.setProperty("http.proxyHost", "127.0.0.1");
	 * System.setProperty("http.proxyPort", "8888");		  
	 * */
	
	
	JsoupGet myGet = new JsoupGet();
	Document doc;
	doc = myGet.GetUrl("http://www.baidu.com");//不带参数方法
			
	//doc = myGet.GetUrl("http://yuedu.baidu.com/search", "云层","0");//带参数方法
	
	//利用css获取内容，用select做断言
	Elements elements = doc.select(".mnav");
	
	//获得第一个元素first，获得指定序列的元素get
	System.out.println(elements.first().toString());
	System.out.println(elements.get(1).toString());
	//获取第一个元素
	Element element =elements.first();
	
	if (element.toString().contains("糯米"))
		System.out.println("断言成功");
	else
		System.out.println("断言失败");
	
	
}
