安卓第三方百度网盘下载,百度网盘第三方登录

简单介绍实现过程：服务器通过网站访问创建的项目-项目返回到包含登录按钮的页面-服务器单击返回到项目跳转页面，并在后台获取代码值-提示服务器将access_token-后台获取的附加信息(如用户登录的ID、密码等)返回给服务器-服务器进行显示

具体实现过程：百度互联网开发者中心搜索

稍后点击登录，没有百度账户的收件人注册

点击申请记录

点击百度云官网

出现再次登录的画面，登录后出现提示，充实信息

当系统提示激活时，单击“创建项目”

输入工程名称，后两个不选择，根据需要选择

创建成功后显示

单击左侧的“安全设置许可证”

输入发布服务器的服务器信息。不能选择以下访问限制：你需要保证和自己的项目一致

例如：

完成后会显示提示

打开eclipse，然后打开web项目、servlet文件(例如BaiDu.)

新建jsp（如：index.jsp）文件，写入：

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<script type="text/javascript">
function bdlogin(){
location.rel="external nofollow" href="https://openapi.baidu.com/oauth/2.0/authorize?response_type=code&client_id=4wdxaiHN6vzfGC2fiINDkT4p&redirect_uri=http://www.tanaixing.top/venu/BaiDuServlet&display=popup";
}
</script>
<body>
<input type="button" value="百度登录" οnclick="bdlogin()">
</body>
</html>

再新建一个jsp文件（服务器输出信息），写入：

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<%=request.getAttribute("message") %>
</body>
</html>
