java的Jsoup登录有验证码网页获取登录后的cookie
首先是jar仓库：
dependency
groupIdorg.seleniumhq.selenium/groupId
artifactIdselenium-java/artifactId
version[3.0.1,)/version//获取最新的版本库
/dependency
dependency
groupIdorg.jsoup/groupId
artifactIdjsoup/artifactId
version1.8.2/version
typejar/type
/dependency
代码：
public static void getIndex2() {
//之前运行程序发现生成了N多个chrome driver进程，搞不懂为什么会有那么多进程产生，网上查了下，说起这个service有用，拿来试下，效果未知
ChromeDriverService service = new
ChromeDriverService.Builder().usingDriverExecutable(new
File("./driver/chromedriver.exe")).usingAnyFreePort().build();
try {
service.start();
} catch (IOException ex) {
Logger.getLogger(kechengbiaoIndex.class.getName()).log(Level.SEVERE, null, ex);
}
//end
//正式开始
//先定义浏览器驱动，我用chrome浏览器，网上下载一个chromedriver.exe，启动时需要加载
System.getProperties().setProperty("webdriver.chrome.driver", "./driver/chromedriver.exe");
如何用js向cookie中保存数据，取数据。
可以使用jquery.cookie.js扩展包，先到网络上下载好
使用方法：
前后html省略
script src="/js/jquery.cookie.js"/script
script
//设置cookie
//test为键名，1为键值，第三个参数是失效时间
$.cookie("test", "1", { expires: 7 }); // 存储一个带7天期限的 cookie
//读取cookie
$.cookie("test");
//删除cookie
$.cookie("test", "1", { expires: -1 }); //设置过期时间为负就失效了
/script
如何用js向cookie中保存数据、取数据？
用js向cookie中保存数据、获取数据的方法如下：
function GetCookieVal(offset)
//获得Cookie解码后的值
{
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
//---------------------------
function SetCookie(name, value)
//设定Cookie值
{
var expdate = new Date();
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc 2) ? argv[2] : null;
var path = (argc 3) ? argv[3] : null;
var domain = (argc 4) ? argv[4] : null;
var secure = (argc 5) ? argv[5] : false;
if(expires!=null) expdate.setTime(expdate.getTime() + ( expires * 1000 ));
document.cookie = name + "=" + escape (value) +((expires == null) ? "" : ("; expires="+ expdate.toGMTString()))
+((path == null) ? "" : ("; path=" + path)) +((domain == null) ? "" : ("; domain=" + domain))
+((secure == true) ? "; secure" : "");
}
//---------------------------------
function DelCookie(name)
//删除Cookie
{
var exp = new Date();
exp.setTime (exp.getTime() - 1);
var cval = GetCookie (name);
document.cookie = name + "=" + cval + "; expires="+ exp.toGMTString();
}
//------------------------------------
function GetCookie(name)
//获得Cookie的原始值
{
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i clen)
{
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return GetCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
SetCookie("username1",99);
alert(GetCookie("username1"));
