QQ第三方授权登录+阿里云短信服务

一、简介

目前我们使用的web系统在登陆功能开发时，不仅仅只是单纯的使用表单填写用户注册信息来进行注册，参考我们现在使用的其他软件存在以下登录情况。

1. 使用QQ/微信等第三方平台进行授权登录
2. 使用短信验证码进行登录

常见的就是着两种登录方式，他们使用的频率比单纯的表单填写信息更加的美观。

注意：我们这篇文章只是让我们了解第三方平台账号授权和手机验证码，在此不过多关注和区分登录和注册的逻辑。

二、QQ第三方授权登录

1.获得QQ的权限

进入QQ互联—>点击头像填写个人信息—>应用管理

（审核需要一定的时间）可以参考QQ互联文档资料

2.代码的编写

2.1添加依赖

我们再springboot实现该功能

	<!-- 以下是 qq 登陆需要的相关依赖工具 commons-io， commons-lang3，httpclient，fastjson-->
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-io</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.38</version>
        </dependency>

2.2配置文件信息

填写QQ互联的Appid，key，登录后回调地址（必须和QQ互联填写的一致，QQLogin 对应代码里的接口）

constants.qqAppId=101513767
constants.qqAppSecret=b1d978cefcf405388893d8e686d307b0
constants.qqRedirectUrl=http://127.0.0.1:8080/QQLogin

2.3读取配置信息类

@Component
public class Constants {

	@Value("${constants.qqAppId}")
	private String qqAppId;

	@Value("${constants.qqAppSecret}")
	private String qqAppSecret;

	@Value("${constants.qqRedirectUrl}")
	private String qqRedirectUrl;

	@Value("${constants.weCatAppId}")
	private String weCatAppId;

	@Value("${constants.weCatAppSecret}")
	private String weCatAppSecret;

	@Value("${constants.weCatRedirectUrl}")
	private String weCatRedirectUrl;

	//自行生成set get方法
}

2.4QQ数据实体类

QQ将把返回的信息封装到这里

public class QQUserInfo {

	private Integer ret;
	private String msg;
	private Integer is_lost;
	private String nickname;
	private String gender;
	private String province;
	private String city;
	private String year;
	private String constellation;
	private String figureurl;
	private String figureurl_1;
	private String figureurl_2;
	private String figureurl_qq;
	private String figureurl_qq_1;
	private String figureurl_qq_2;
	private String is_yellow_vip;
	private String vip;
	private String yellow_vip_level;
	private String level;
	private String is_yellow_year_vip;
	
   //自行生成 set get
}

2.5http工具类 HttpClientUtils

2.6url转码工具类 URLEncodeUtil

不管是以何种方式传递url时，如果要传递的url中包含特殊字符，如想要传递一个+，但是这个+会被url会被编码成空格，想要传递&，被url处理成分隔符。所以都会做一下url转码的工作。

public class URLEncodeUtil {

    private final static String ENCODE = "UTF-8";
    /**
     * URL 解码
     */
    public static String getURLDecoderString(String str) {
        String result = "";
        if (null == str) {
            return "";
        }
        try {
            result = java.net.URLDecoder.decode(str, ENCODE);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return result;
    }
    /**
     * URL 转码
     */
    public static String getURLEncoderString(String str) {
        String result = "";
        if (null == str) {
            return "";
        }
        try {
            result = java.net.URLEncoder.encode(str, ENCODE);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        return result;
    }

2.8效果

授权后返回的信息

二、短信授权登录

短信登陆可以参考：微信开放平台官方文档

三、短信验证登录

我们使用阿里云短信服务来完成发送验证码

1.阿里云短息服务

进去阿里云，搜索短信服务，完成学习应该就了解的差不多了

1.添加签名和模板

• 选择左侧的国内消
• 签名管理中选择添加签名（签名就是发送短信时的程序名或公司名）需审核
• 模板管理添加模板（也就是发送短信的内容）需审核

2.获取自己的阿里云私匙

• 左侧点击概览
• 选择AccessKey（获得私匙）

2.代码实现

可以参考OpenAPI Explorer
