本文主要介紹了springboot+jwt+微信小程序授權(quán)登錄獲取token的方法實(shí)例，文中通過(guò)示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

前言

我們有時(shí)候在開(kāi)發(fā)中，遇到這樣的問(wèn)題，就是我們需要小程序授權(quán)登錄我們自己的后臺(tái)，通過(guò)小程序的信息換取我們自己后臺(tái)的token，實(shí)現(xiàn)賬號(hào)密碼、小程序授權(quán)登錄的多種登錄方式。

配置

在 SecurityConfig文件中配置

XcxAuthenticationProvider

public class XcxAuthenticationProvider implements AuthenticationProvider {
    private UserDetailsService userDetailsService;

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        XcxAuthenticationToken authenticationToken = (XcxAuthenticationToken) authentication;

        String openId = (String) authenticationToken.getPrincipal();


        XcxUserService service= SpringContextUtil.getContext().getBean(XcxUserService.class);

        UserDetails userDetails = service.loadUserByOpenId(openId);

        // 此時(shí)鑒權(quán)成功后，應(yīng)當(dāng)重新 new 一個(gè)擁有鑒權(quán)的 authenticationResult 返回
        XcxAuthenticationToken authenticationResult = new XcxAuthenticationToken(userDetails, userDetails.getAuthorities());

        authenticationResult.setDetails(authenticationToken.getDetails());

        return authenticationResult;
    }


    @Override
    public boolean supports(Class<?> authentication) {
        // 判斷 authentication 是不是 SmsCodeAuthenticationToken 的子類或子接口
        return XcxAuthenticationToken.class.isAssignableFrom(authentication);
    }

    public UserDetailsService getUserDetailsService() {
        return userDetailsService;
    }

    public void setUserDetailsService(UserDetailsService userDetailsService) {
        this.userDetailsService = userDetailsService;
    }
}

XcxAuthenticationToken

public class XcxAuthenticationToken extends AbstractAuthenticationToken { private static final long serialVersionUID = 420L;
    private final Object principal;

    /**
     * 沒(méi)登錄之前,principal我們使用手機(jī)號(hào)
     * @param openid
     */
    public XcxAuthenticationToken(String openid) {
        super((Collection)null);
        this.principal = openid;
        this.setAuthenticated(false);
    }

    /**
     * 登錄認(rèn)證之后,principal我們使用用戶信息
     * @param principal
     * @param authorities
     */
    public XcxAuthenticationToken(Object principal, Collection<? extends GrantedAuthority> authorities) {
        super(authorities);
        this.principal = principal;
        super.setAuthenticated(true);
    }
    public Object getCredentials() {
        return null;
    }
    public Object getPrincipal() {
        return this.principal;
    }
    public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException {
        if (isAuthenticated) {
            throw new IllegalArgumentException("Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead");
        } else {
            super.setAuthenticated(false);
        }
    }
    public void eraseCredentials() {
        super.eraseCredentials();
    }
}

小程序授權(quán)登錄

@RestController
@RequestMapping("/xcx")
@AllArgsConstructor
@Api(value = "認(rèn)證模塊", tags = "認(rèn)證模塊")
public class XcxAuthController {

    private JwtService jwtService;
    private JwtUserDetail jwtUserDetail;
    private XcxUserService userService;
    private AuthenticationManager authenticationManager;

    @RequestMapping(value = "/login", method = RequestMethod.POST)
    @ApiOperation(value = "登錄", notes = "登錄")
    public Result login(@RequestBody Map<String, Object> map) {
        HashMap<String, Object> hashMap = new HashMap<>();
        String code = String.valueOf(map.get("code"));
        try {
            WxMaService wxMaService = WxMaConfiguration.getWxMaService();
            WxMaJscode2SessionResult session = wxMaService.getUserService().getSessionInfo(code);

            XcxUser user = userService.getOne(Wrappers.<XcxUser>lambdaQuery()
                        .eq(XcxUser::getOpenId, session.getOpenid()), false);
                if (ObjectUtil.isNull(user)) {
                    //過(guò)濾掉表情
                    user = XcxUser.builder()
                            .openId(session.getOpenid())
//                        .nickname(wxMpUser.getNickName())
//                        .avatar(wxMpUser.getAvatarUrl())
                            .build();
                userService.save(user);
            } else {
                userService.updateById(user);
            }
            UserDetails userDetails = jwtUserDetail.loadUserByOpenId(session.getOpenid());
            authenticationManager.authenticate(new XcxAuthenticationToken(session.getOpenid()));
            Map<String, Object> parse = JSON.parseObject(JSON.toJSONString(userDetails), Map.class);
            String token = jwtService.createToken(parse);
            hashMap.put("token", token);
            hashMap.put("user", userDetails);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return Result.success(hashMap);
    }


}
