(六)、引入uni-id用户体系，基于opendb创建schema，向数据库添加新数据【uniapp+uinicloud多用户社区博客实战项目(完整开发文档-从零到完整项目)】

1，uni-id-pages

uni-id-pages链接
提供了一批现成的、开源的、登录注册账户管理相关的前端页面和云端云对象。

1.1 引入uni-id-pages

从dcloud插件市场通过hbuilder导入的方式引入

1.2 云端配置config.json

uni-id的云端配置文件在uniCloud/cloudfunctions/common/uni-config-center/uni-id/config.json中。

config.json

    },
    "univerify": {
      "appid": "",

1.3 切换到登录地址–注册新账号

http://localhost:8080/#/uni_modules/uni-id-pages/pages/login/login-withpwd

注册新账号

1.4 云数据库中查看账号信息（表明已经注册成功）

2，利用opendb创建文章的schema文件

2.1 新建文章schema

2.2 quanzi_articles.schema.json

{

3，向云数据库添加新数据

3.1 添加数据方法

在script中，声明db实列对象

  const db = uniCloud.database()

添加数据方法

      //添加数据到云数据库quanzi_articles
      async addData() {
        await db.collection("quanzi_articles").add({
          ...this.artObj
        }).then(res => {
          uni.hideLoading();
          uni.showToast({
            title: "发布成功"
          })
          setTimeout(() => {
            uni.reLaunch({
              url: "/pages/index/index"
            })
          }, 800)
        })
      },

3.2 测试

添加数据

数据库中查看：
