支付宝账号登陆小程序

修改application.yml文件

修改ZfbController中的值注入

@Value("${application.alipay.microApp.app-id}")
private String microApp_appId;

@Value("${application.alipay.microApp.public-key}")
private String microApp_publicKey;

@Value("${application.alipay.microApp.private-key}")
private String microApp_privateKey;

@Value("${application.alipay.app.app-id}")
private String app_appId;

@Value("${application.alipay.app.public-key}")
private String app_publicKey;

@Value("${application.alipay.app.private-key}")
private String app_privateKey;

@Value("${application.alipay.gateway}")
private String gateway;

编写ZfbLoginForm.java

@Data
@ApiModel(value = "支付宝登录表单")
public class ZfbLoginForm {
    @ApiModelProperty(value = "临时登陆凭证")
    @NotBlank(message="临时登陆凭证不能为空")
    private String authCode;

    @ApiModelProperty(value = "昵称")
    @NotBlank(message="昵称不能为空")
    private String nickname;

    @ApiModelProperty(value = "头像URL")
    @NotBlank(message="头像URL不能为空")
    private String photo;

}

编写ZfbController.java中的登陆方法

@PostMapping("login")
@ApiOperation("登录")
public R login(@RequestBody ZfbLoginForm form) {
    //表单校验
    ValidatorUtils.validateEntity(form);

    AlipayClient client = new DefaultAlipayClient(gateway, microApp_appId,
            microApp_privateKey, "json", "UTF-8", microApp_publicKey,
            "RSA2");
    AlipaySystemOauthTokenRequest request = new AlipaySystemOauthTokenRequest();
    request.setGrantType("authorization_code");
    request.setCode(form.getAuthCode());
    try {
        AlipaySystemOauthTokenResponse response = client.execute(request);
        if (response.isSuccess()) {
            String userId = response.getUserId();
            UserEntity user = new UserEntity();
            user.setOpenId(userId);
            QueryWrapper wrapper = new QueryWrapper(user);
            int count = userService.count(wrapper);
            if (count == 0) {
                user.setNickname(form.getNickname());
                user.setPhoto(form.getPhoto());
                user.setType(2);
                user.setCreateTime(new Date());
                userService.save(user);
            }
            user = new UserEntity();
            user.setOpenId(userId);
            wrapper = new QueryWrapper(user);
            user = userService.getOne(wrapper);
            long id = user.getUserId();

            String token = jwtUtils.generateToken(id);

            Map<String, Object> result = new HashMap<>();
            result.put("token", token);
            result.put("expire", jwtUtils.getExpire());

            return R.ok(result);
        } else {
            return R.error("登陆授权失败");
        }
    } catch (Exception e) {
        e.printStackTrace();
        return R.error("登陆授权失败");
    }
}

编写小程序登陆代码

my.getAuthCode({
    scopes: "auth_user",
    success: function(resp) {
        let authCode = resp.authCode
        my.getAuthUserInfo({
            success: function(resp) {
                let nickName = resp.nickName
                let avatar = resp.avatar
                uni.request({
                    url: that.url.zfb.login,
                    method: "POST",
                    data: {
                        "authCode": authCode,
                        "nickname": nickName,
                        "photo": avatar
                    },
                    success: function(resp) {
                        console.log(resp)
                        let token = resp.data.token
                        let expire = resp.data.expire
                        console.log(token)
                        uni.setStorageSync("token", token)
                        uni.setStorageSync("expire", expire)
                        uni.switchTab({
                            url: "../index/index"
                        })
                    }
                })
            }
        })
    }
})
