setting页面点击用户资料跳转到user_info页面，别忘了在pages.json注册新页面

<navigator url="../user_info/user_info">
    个人资料
</navigator>

user_info页面对头像做点击事件，点击弹出ActionSheet

<image :src="avatar" class="avatar" @tap="showActionSheet"></image>

js部分的data数据

data() {
        return {
            nickname: uni.getStorageSync('login_key').nickname,
            avatar: uni.getStorageSync('login_key').avatar,
            userId: uni.getStorageSync('login_key').userId
        };
    }

showActionSheet函数

showActionSheet: function() {
            var _this = this;
            uni.showActionSheet({
                itemList: ['拍照', '从相册选择'],
                success: function(res) {
                    console.log('选中了第' + (res.tapIndex + 1) + '个按钮');
                    //选择的是拍照功能
                    if (res.tapIndex == 0) {
                        uni.chooseImage({
                            count: 1,
